India

Basics
India has the fastest growing telecom market in the world with almost 1 billion subscribers. It's also one of the most chaotic to foreigners. A lot of operators used to share the market:

Bharti Airtel (in merger talks with Tata and bought Telenor), Vodafone India (to be merged with Idea), Idea Cellular (to be merged with Vodafone), Reliance JIO (on 4G/LTE-only), Aircel (to be merged with RCom), Reliance Communications (RCom) (to be merged with Aircel), Telenor India (sold to Airtel), BSNL (to be merged with MTNL), Tata DoCoMo (in merger talks with Airtel), MTNL (to be merged with BSNL).

Operators and mergers
Jio shook the market when it arrived on the scene with predatory pricing in 2016/7. The reaction is a wave of consolidation, with mergers planned or done between: Vodafone India and Idea Cellular; Reliance Communications (RCom) and Aircel with the new company Aircom; and Airtel with Telenor India. The government is also expected to merge state-owned operators BSNL and MTNL, but no plans have been confirmed. Should the current raft of mergers all be completed, the nation’s mobile market would slim down from 11 to only 5 operators with the following market shares (based on subscriber totals in 2017):
 * Vodafone + Idea Cellular: 35%
 * Bharti Airtel + + Telenor India: 32%
 * Aircom: Reliance Comm. + Aircel: 15%
 * Reliance Jio: 9%
 * BSNL + MTNL: 9%

Frequencies
Besides GSM networks, WIMAX and CDMA is used too, but not part of this survey. CDMA is progressively shut down and the spectrum is refarmed to LTE. So it usually makes no sense to activate CDMA subscriptions.
 * 2G/GSM
 * 900 MHz (Band 8): used by Airtel, Vodafone, Idea, Aircom, MTNL/BSNL
 * 1800 MHz (Band 3): used by all operators (except Jio)
 * 3G/UMTS/HSPA
 * 2100 MHz (Band 1): used by all major providers (except Jio)
 * 4G/LTE
 * 700 MHz (Band 28): freed from digital TV, prepared for LTE
 * 850 MHz (Band 5): previously CDMA, re-auctioned to Jio, Aircom, Tata, MTNL/BSNL
 * 1800 MHz (Band 3): used by Airtel, Vodafone, Idea and Jio
 * 2300 MHz (Band 40 - TDD-LTE): used by Jio, Airtel, Idea
 * 2600 MHz (Band 41 - TDD-LTE): used by Vodafone and Idea, intended for BSNL

Coverage
India is diverted into 22 mobile telephone markets called circles. All licenses were given out per circle. So there is a considerate fragmentation especially when it comes to 4G/LTE. Some spectrum was re-auctioned in 2016 and the current holdings per circle can be found here.

You can never really rely on one network only as blackouts and congestions are frequent. At other times and places, you may also get worldclass speed and coverage.

All major operators (except Jio) have coverage in all circles when it comes to 2G/3G. The 4G market is much more fragmented. Only Jio, Idea and Airtel have started in major towns in all circles by 2017, but often on unusual TDD-LTE bands, Vodafone is expected to follow soon.

Legal requirements
It's theoretically easy to get a prepaid SIM card in India as a foreigner, you just have to make sure you have all the proper documents and they'll probably want photocopies of them too. These documents you'll probably need: You will need to present these, along with your original passport document, to the SIM vendor. The Indian Government has recently put in restrictions that puts a 3 month limit on prepaid SIM connectivity for foreign visitors to India. Cellphone vendors cannot sell SIM cards with longer than 3 months validity.
 * make a copy of the photo / name page of your passport ,
 * a copy of the Indian visa page in your passport (or your OCI card),
 * and a  passport sized picture  as well.
 * Get a proof of where you're staying in India . If you're in a hotel, you should be able to get a letter from the frontdesk verifying that you are indeed staying there.
 * If your passport doesn't have a home address, try to show something which looks official with it.

As of November 2012, there has been a significant tightening of regulations around the purchase and activation of SIM cards. Some operators are saying that it will take at least 4 days to activate a SIM card once purchased. Officially, this process takes 24-48 hours. In practice, some SIMs are activated within 12 hours since the rule has changed, and other SIMs have taken almost a week to activate. And, just to make things more difficult, there is very little rhyme, reason or logic to how long any of these things take.

In 2015 the process seems mostly to be a bit swifter. Many people report that their SIM cards were activated within 2 days. For latest reports and updates check this forum. But you still have to be prepared that it takes quite a while and you may be called to confirm your identity or local address. Some users finally gave up during the lenghty process.

Miracously, there are also opposite reports especially from tourist locations, where users needed to pay some extra fees like Rs. 700 to bypass the paperwork and skip activation time. These SIM cards usually work for 30 days only. In 2017 the goverment and the national tourist office stated that tourists need to wait for 5-6 hours on average for activating a new SIM Card, and after providing all relevant documents. So things seem to have speeded up.

Effective February 2017 state-run provider BSNL started to offer pre-activated SIM cards to tourists after some relaxing in activation done by the government. These are given out at 15 airports in the country to tourists of 161 countries on eVisas. For more info see BSNL section below.

Because of the legal hassle at the end of this article a travel solution for India with a phone rental including data SIM is added. With Trabug you'll pay a heavy surcharge, but can pre-arrange your SIM and can be sure that it will work in the country rightaway.

Availability
Most international airports in India have counters where you can buy SIM cards. These counters are usually located right after you clear customs. For the most part, if you have the above documents in order, you should be able to get your card in 15-20 minutes after you fill out the required documentation.

If you don't get one at the airport, you should be able to get a prepaid SIM card at a local, independent cellphone dealer. If you have all the documents in place, it will make it much easier for them and will lead to less hassle.

Regional organization
When starting up, be sure to enable (domestic) roaming as the networks are organized on a state (circle) level. Different prices and offers apply to every circle in India. Jio started with agressiv princing in 2016/7 and so far most operators have announced to scrap all domestic roaming charges within India by 2017.

Special rules for Jammu and Kashmir state
A prepaid SIM card bought and registered somewhere in India, can be used all over the union, except in Jammu and Kashmir (State of North India) this is because of the fear of terrorism. Only a new prepaid SIM, bought in J&K works in this state. There the restrictions are even higher: you will need 4 passport photos, copies of your passport and your local sponsor (hotel manager or local counterpart) and expect that activation takes even longer. J&K SIM cards have reduced functionality: You can't receive or send text messages and the number of the prepaid subscriber from Jammu and Kashmir won't work outside the state. This restriction has been extended to 2018.

Survey of providers
Unlike most other countries, in the following list no survey of data rates is given. This is because India has become a very dynamic market with many special offers which often differ between circles. Therefore we characterize every provider and link to their data plans instead. Links on this Wiki have the problem of getting broken as soon as the provider redesigns its website. So for a general survey of all providers, circles and mobile plans check on reload.in or compare plans on komparify.com/operators.

Airtel (Bharti Airtel)
Airtel (a.k.a. as Bharti Airtel) is the biggest provider in India. It has about 280 million mobile subscribers in 2017 and still the widest coverage. In 2017 it plans to take over Telenor which is getting all the required approvals and it's in talks with Tata to do the same as the latter is trying to exit the Indian market. This would build the second biggest mobile provider aside of Vodafone/Idea soon with sharply falling revenues. Airtel has about 35% revenue market share in 2017 and gained by the exit of as smaller telcos the acquisition of Telenor.

Airtel offers 2G/3G in all circles partly through roaming agreements. 4G/LTE is available in 591 cities so far in all circles, but it's open for prepaid in only in a part of them: Airtel's 4G cities. Note, that Airtel uses mostly 2300 MHz (on band 40, in unpaired TDD-LTE), but lately the more common 1800 MHz (band 3) for LTE too.

The incumbents have come under extreme pressure because of Jio's agressive pricing in 2016/7. Airtel announced scrapping all national roaming charges for voice, SMS and data from April 2017. Users recommend Airtel especially for the metropolitan areas.

Availability
An Airtel SIM card costs Rs. 50-100, some vendors may charge more. Lifetime validity requires a recharge of Rs. 49. Swapping a 3G SIM to a 4G SIM is free.

Activation takes two hours up to some days. 3G/4G activation takes up another four hours after intial SIM card activation. When you buy the card, initially you will have no network; after some hours, you'll notice network availability; call 59059 to activate. You'll need to give the last four digits of your ID.

Any Airtel number will be released, if not logged into the network for 30 days. Credit balance check: *123#, remaining data check: *123*11# . Click here for many other useful codes.

Data offers
Default data depending on prepaid tariff line and region and is mostly around 4p per 10 KB.

Airtel always offers promotions for new customers and their first time recharge. So ask for it. Afterwards 3G/4G data "normal" recharge price applies and they differ between circles. There are no manual activations as such, once the credit is added the data package is activated automatically, with a SMS notification. So every top-up correspondents with a certain allowance. Be sure to top-up the right amount exactly to get the right bundle.

As the top-up face prices and packages sizes differ for every circle, it's not useful to give prices here as they will be changed to a totally different package in a different circle: 4G/LTE is available for prepaid in about 100 towns so far in 2016 like Mumbai, Kolkata, Delhi and many others. To counter Jio's offensive, Airtel has come up with some remarkable deals:
 * for 2G packages (less useful): select "prepaid" and circle and check here
 * for 3G packages: select circle and check here
 * for 4G/LTE packages: select city and check here (scroll down to red boxes)
 * Airtel is offering a prepaid plan of Rs 799 focussed for high volume data users. The Rs 799 plan offers 3 GB per day of 2G/3G/4G data and unlimited local and STD calls (= calls between circles) to any network for 28 days.


 * Airtel’s Rs 399 plan gives users unlimited local and STD calls plus 1 GB 4G data per day with a validity of 70 days. Airtel users should be able to check for the plan in ‘Best offers for you’ category in MyAirtel app. It's available on the company’s website as well.


 * Airtel has a couple of other good deals as well. For example, the Rs 345 plan gives users unlimited local and STD calls as well as 2 GB data per day for 28 days. For high-end data users, Airtel has a Rs 549 plan with unlimited local and STD calls plus unlimited data (2.5 GB per day) for 28 days.

To apply a feature data pack, you can ask at any shop showing the Airtel logo, which are very widespread. Contrary to most countries, don't just buy the airtime - you need to buy and apply data packs separately.
 * There are Airtel’s data-only plans for Rs 29 and Rs 98. The Rs 29 plan offers 200 MB 3G/4G data for 30 days, while users will get 1 GB 2G data for 28 days if they recharge with Rs 98.

There are lots of special offers, and data packs can be shared with up to five 'family' members. It's worth downloading the My Airtel app to see all offers and easily apply them; this is only available on the Indian App and Play stores, but hot to install it on a device from outside is shown here.

Domestic roaming has to be switched on to use internet outside the state you purchased the SIM from. But there are no extra charges for this domestic data roaming, but for phone calls there are roaming charges.

Vodafone India (to be merged with Idea)
Vodafone has the 2nd most subscribers in India with 200 million customers in 2016 and is one of the better networks for metropolitan coverage. Some locals consider its 3G as fastest and most reliable in India recommended for the cities.

Vodafone has 2G/3G coverage in all circles partly through roaming agreements with Idea. In 2015 4G/LTE on 1800 MHz (Band 3) has started in Kochi and has spread to Mumbai, Delhi, Bengaluru and Kolkata and more places in 2016.

In March 2017 Vodafone India agreed to a merger with Idea Cellular, through which the two will create a combined entity with a market share of over 35% and thereby India's largest operator. The merger would also help both the telecom operators withstand intense price competition brought by Jio. The combined entity of Vodafone India and Idea Cellular will have a more balanced subscriber mix, as Vodafone is strong in urban areas whereas Idea focuses more on the rural mass market. The brand strategy of the new company will be determined at a later date.

Availability
SIM card costs: Rs. 50-100, various vendors may charge whatever they feel like. Recharges are made in their shops or online from Rs. 111 for a credit of Rs. 105 to Rs. 1000.

The most useful USSD codes to manage a Vodafone SIM can be found [http://www.imobileandroid.com/vodafone-ussd-codes-check-balance-offer-plan-alert/#! here.]

Data offers
Default rate outside of packs is on most prepaid tariffs and circles is around 4p per 10 KB. For prepaid they 4G/LTE, 2G and 3G is widespread available. Like Airtel, their rates and package sizes differ very much from circle to circle. So it doesn't make sense to quote prices here. Some special offers may be available: pack from a Vodafone outlet as the plan is not available on the Vodafone website and MyVodafone app.
 * 2G, 3G and 4G/LTE packages: select and circle here on top right
 * Vodafone has launched a Rs 352 prepaid recharge pack that provides customers 1 GB data per day for 56 days. In addition to this, you get unlimited local and STD calls to any network during the validity period. To avail the benefits of the pack, you need to buy the recharge
 * Later Vodafone announced a Rs 19 recharge pack that offered one day of validity with 100 MB of 4G data and unlimited local and STD calls to Vodafone network only. Vodafone also launched Rs 49 and Rs 89 recharge plans that offered 7 days of validity with 250 MB of 4G data and unlimited local and STD calls on other networks for 100 minutes.
 * In June 2017, Vodafone launched the Rs 29 recharge pack, meant only for data usage in the night 1am-6am, that offered unlimited Internet 3G/ 4G data to the users.


 * Later Vodafone unveiled a Rs 445 plan which was later discounted to Rs. 244. The plan offers 1 GB data per day, matching rival operators plans, "unlimited" Vodafone to Vodafone voice calls valid for 70 days. So, you can enjoy voice calls and 1 GB data per day for 70 days at US$ 7.

International roaming offers
Vodafone has the best international roaming offer on the Indian market called iRoam Free. These roaming plans come in different time frames beween 1 day at Rs 500 and 30 days at Rs 5000 (for full list see here). These packages are valid in 40 countries. In the USA, Singapore and UAE calls and data, both incoming and outgoing while travelling in these countries are completely surcharge free. In 37 further countries: France, Germany, Italy, Ireland, Spain, Greece, Switzerland, Singapore, Australia, Hong Kong, Thailand, Malaysia, Turkey, Belgium, Netherlands, Norway, Denmark, Czech Republic, Portugal, Romania, Albania, Hungary, Luxembourg, Canada, Saudi Arabia, Oman, Qatar, Kuwait, Sri Lanka, New Zealand, Japan, Korea, Russia, Taiwan, Mauritius, and Morocco all incoming calls are free, and data plus outgoing calls being nominally charged at Rs 1 per MB and Rs 1 per minute respectively.

Idea Cellular (to be merged with Vodafone)
Idea is the 3rd provider in India with 189 million subscribers in 2017. It has 3G licences in 11 circles and offers services in all circles through network sharing with Vodafone and Aircel. For a survey, check their website or here.

In 2015 it started with 4G/LTE and in 2017 it already covers 200 cities in about 10 circles (list) on 1800 MHz (band 3) where it has own coverage and is considered to be particulary strong.

As 2nd incumbent after Airtel Idea announced the drop of all national roaming charges on voice, SMS and data from April 2017 as a reaction to Jio's agressive pricing.

In March 2017 Idea Cellular agreed to a merger with Vodafone India, through which the two will create a combined entity with a market share of over 35% and India's largest operator. The merger will end in both companies having a 50% share. The brand strategy of the new company will be determined at a later date (see Vodafone above).

Availability
SIM card costs Rs.10 + 1.10 tax, various vendors may charge whatever they feel like. Default data rate is around 3p per 10 KB. For USSD codes that can be used to manage your SIM, [http://www.imobileandroid.com/ussd-code-idea-cellular/#! check here].

For 2G/3G you need to check their website here and first select circle on the right. Idea is besides of Airtel and Jio the only provider offer 4G in all circles. For 4G prices and packages check their website here and first select circle.
 * Idea Cellular entered the data tariff war in March 2017. In June, Idea came up with a recharge pack worth Rs 396 with a 70-day validity that offered 1GB 3G/4G (varies with circle) data per day. Additionally, the customers also received unlimited calls for the 70-day validity period, but only to other Idea numbers. Un-billed calls to other networks were capped at 3,000 minutes for the whole validity.


 * In summer 2017 Idea is giving 6 GB 3G data at Rs. 96 for 28 days. Apart from this, the Rs. 396 is still available for Idea prepaid customers. he Rs. 297 plan has been revised to Rs. 244 with 1GB data per day for 70 days on a 4G SIM and 4G smartphone. The offer comes with voice airtime. There's also a Rs 197 recharge plan that will give you unlimited local and STD calls along with just 1 GB of monthly data for 28 days.


 * The latest Idea offer to take on Jio is the new Rs 453 prepaid pack, which provides 84 GB of data for 84 days, with a 1 GB daily data cap. The data is limited to 3G speeds, and the buyer also gets bundled calls (300 minutes per day and 1,200 minutes per week) for the validity period.

Reliance Communications (RCom) soon to be Aircom
Reliance Communications (RCom) is still the 4th provider in India holding licenses in all 22 circles on 2G or 3G only. It runs a CDMA network too (which is incompatible to GSM) that is about to be shut down. It's 4G is only through network sharing with Jio (see below).

In September 2016 it was announced that it has acquired Aircel (see below) to be merged to their network soon. RCom also adopted MTS India. The Aircel merger is supposed to be completed by the end of 2017 and the new company was unveiled as '''Aircom. '''They will have the second-largest spectrum among all the players in the country.

Availability
SIM card costs: Rs. 50-100, various vendors may charge whatever they feel like. USSD codes to manage the SIM can be found here.

Data offers
Their pay as you go rate is a pretty high 10 Rs. per 10 KB.

For some states, they have special plans, packages and offers you can check here.

It looks like RCom learnt a lesson for not launching attractive tariff plans when incumbent operators such as Jio, Bharti, Airtel, etc. were luring customers.
 * RCom is now offering 1 GB of 2G data per day for 365 days with a recharge of Rs 365. The recharge amount might differ from circle to circle, and so does the validity. The 2G data seems to be a huge letdown because other operators are providing 4G data at the same price. But none of the operators have been offering it for 365 days like RCom.
 * Recently, RCom launched a new plan of Rs 193 for its prepaid customers, where it is offering 1 GB of 4G data per day for 28 days, which is on par with other telecom operator plans.

Reliance Jio
Reliance Jio Infocomm (RJIL), the mobile arm of petrochemical giant Reliance Industries Ltd. (RIL) owned by India's richest man Mukesh Ambani, started its new 4G-only network in 2015/6 nationwide.

This is the company everybody is afraid of. In 2016 RJIL started a price war with their new 4G/LTE network. The operator currently covers 90% of the population with 4G/LTE in all circles. It has twice as many towers for 4G than all its competitors combined, but on Jio, there is no fallback to 2G or 3G. You'll need to have a device capable of LTE on 2300 MHz in TDD-LTE (band 40). Jio claims to have the double average speed with 16 Mbps compared to its competitors, but Open Signal tests proved otherwise and showed slower speeds than Aircel, Vodafone and Idea.

It's recommended to take Jio only for data or if you have a VoLTE enabled device as the voice service is completely based on VoLTE.

The start
Under it's welcome offer, all Jio services including voice, apps, and 4G/LTE data were available free until March 2017 (up to 4 GB per day). Long lines have been building up in front of their stores already. It's the fastest growing technology firm with 100 million customers gained in just 170 days, that's 7 customers per second. As Jio is expected to see a dip in its subscriber base once it begins charging for services in April 2017, they were offering every existing customer Prime membership for once-off Rs. 99. Prime members will be paying only Rs. 303 per month for unlimited data until April 2018.

By the end of March 2017 Jio had 108 million subscribers of which 72 million customers had opted to become Prime members. Jio announced that it would be adding to its more than 100,000 LTE tower sites 100,000 new sites by the end of the year, targeting mobile 4G coverage of 95% of the population.

Availability
As their SIM cards are in high demand, expect delays and problems like overcrowding of their network. Jio faces a blockade of the other carriers e.g. through interconnection issues with the other networks. Jio claims a call failure rate of 175 calls per 1000 calls due to anti-competitive behaviour of the other providers. In 2017 their data download rates which were unreliable at first, seemed to have stabilised nationwide.

Top-up vouchers are sold from Rp. 10-5000 or top-up online. The best way to monitor your consumption is to install their MyJio app.

Data plans
Reliance Jio, which claims to be the world's largest mobile data network, continues to bring about paradigm shifts in the Indian telecom market. Jio has launched new plans to ensure customers get the best deals:
 * First off, there's the Rs 399 pack for another 84 days by providing 1 GB data per day, along with all the other services like free SMS, calls and apps.
 * The other new Jio plan, priced at Rs 349, provides users with 20 GB data for 56 days, with no daily limit on data consumption; however, users will get 10 GB data for the first 28 days and the remaining 10 GB for the other 28 days with this plan, instead of 20 GB together.

All of these plans require Prime membership for Rs. 99. They include free calls (VoLTE only) local, STD and roaming, free SMS to all operators and a data quota: Prices are the same in all circles. Exceeding the FUP, speed will be throttled to 128 kbps.
 * The Rs. 309 and Rs. 509 Jio plans come with 56-day validities, with 1 GB and 2 GB daily data consumption, respectively. The Rs 999 and Rs 1,999 plans, which come with 90 days (90nGB) and 120 days (155 GB) validity. The Rs. 4,999 and Rs. 9,999 plans have been upgraded to provide 210-day (380 GB) and 390-day (780 GB) validities as well.

BSNL
BSNL for Bharat Sanchar Nigam Limited is an Indian state-owned telecommunications company. It operates in all circles except the cities of Mumbai and New Delhi where MTNL operates instead (see below). This provider is seen generally as not so reliable in the cities, but is in some provinces the only available 3G option. So better make a network scan before you buy a SIM card. BSNL holds spectrum for 4G on the unusual 2500 MHz TDD-LTE (band 41) only, but hasn't launched it by now.

It's expected that the state will eventually merge BSNL with MTNL, but no date has been fixed yet.

Availability
They sell a prepaid data SIM with voice for Rs. 20 with a 96 Rs. voucher as a normal SIM or for Rs. 59 as USIM. This includes 500 MB vaild for 30 days. These packages below can be booked for 2G and 3G.

For SIM card management, check out these USSD codes.

Data options
State-owned telco BSNL is not aloof from the ongoing battle amongst the private industry players either. For other plans and latest offers check their website here.
 * In June 2017 the company launched the Rs 444 plan, under which the prepaid subscribers could get 4 GB data per day with a validity of 90 days.
 * In a matter of days, BSNL launched the Sixer 666 pack, priced at Rs 666. It came with 120 GB data bundled with unlimited calls for the prepaid subscribers with a validity of 60 days.

Tourist SIM
In February 2017 BSNL and the government of India launched an initiative to provide tourists a free SIM card at airports. This SIM card comes already pre-activated skipping the lenghty activation process. It is made available at the Indira Gandhi International Airport (T3 Terminal) in New Delhi and over 15 international airports to tourists of 160 countries who are elegible for an eVisa.

Tourists will now be only required to present a copy of their eVisa and the first page of the passport for proof to get the SIM card. The SIM will be loaded with a call credit of Rs. 50 and 50 MB data. It will be active for a month, and tourists will be able to avail the 24-hour helpline in 12 languages.

The initial validity of SIM will be 30 days and there is no international roaming facility. It's unknown if validity can be extended or the SIM can be reloaded. Initially this SIM will have only facility of sending SMS only, not receiving SMS. The customers needs to send a SMS of format ACT  to 9440087000 for an activation of incoming, outgoing voice, data and other facilities on SIM.

However, BSNL having a rather unreliable network without 4G/LTE, it can be still a good option on arrival while activating a SIM of the major private providers, that still takes hours or days.

Aircel (to be mergerd with RCom, soon to be Aircom)
Aircel is the 6th largest mobile provider in India with a market share of about 8%. It's mostly owned by Malaysian Maxis. It has 3G licences for 13 circles and started 4G/LTE as TDD-LTE on 2300 MHz (Band 40) in 2014, that is not available for prepaid yet. You should check 3G availability before on their map.

In September 2016, RCom and Maxis Communications announced that they would merge their mobile network operators. The brand Aircel will eventually be dropped and Aircom will be the new brand.

Availability
Their start-up kit is available where they have a 3G coverage. So you don't find it in Mumbai or Dehli, but in Kolkata. Check aircel coverage map first. It's sold for 28 Rs. including taxes. Top-ups are available Rs. 10-1500. For online recharges, Airtel offers 20% data bonus. To manage your SIM, try these USSD codes.

Data options
Data by default is 15p per MB. Internet packages are called Pocket Internet. For circles and places, check their website and adjust circle on top first.

Aircel has not been as frenzied in launching plans with high bundled data as Airtel, Vodafone, Idea and BSNL to compete with Jio, but has recently released a few to make sure it remains attractive to buyers. All of their offers differ heavily between circles.

TaTa DoCoMo (about to closed down)
Tata Group is planning to close down the wireless operations of its unit in India, which operates via several brands, including Tata DOCOMO and Tata Indicom.

Tata’s loss-making and heavily-indebted telecoms arm initially launched a CDMA network in 2002 before switching on a parallel GSM system in 2008 and later adding W-CDMA in 2010. Despite an injection of capital from a new partner in late 2008/early 2009 in the form of Japan’s NTT DOCOMO, the firm struggled to keep pace with its competitors: its market share peaked at just under 12% in late 2010, and has gradually fallen over the subsequent years, to less than 4% by mid-2017. Tata had considered filing for bankruptcy for the beleaguered unit, but decided against the move due to the potential impact it could have on other Tata companies. The company instead sought to exit the market via a merger or takeover, but talks with a number of prospective buyers including market leader Bharti Airtel, also proved unsuccessful.

TTSL is expected to try and sell the spectrum it won through auctions to other providers to help mitigate its losses, but will likely have to return any administratively awarded frequencies to the government. The company has yet to make an official statement confirming its planned closure, but the cellco has ceased taking on new subscribers in several circles, and a number of senior officials have discussed the group’s exit plan for its roughly 5,000-strong workforce with the press.

Telenor India (to be taken over by Airtel)
Telenor as a branch of the Norwegian provider joined by local Unitech Group is one of the smaller providers in India with only 54 million customers. They only operate in 7 circles across the states of Uttar Pradesh (East and West), Uttarakhand, Bihar, Jharkhand, Maharashtra, Goa, Gujarat, Andhra Pradesh, Madhya Pradesh and Telangana. They currently hold a 1800 MHz license for 2G and 4G/LTE in these circles. It sells SIM cards in their stores (locator) in these circles.

In February 2017 Telenor India agreed to be bought by market leader Airtel (see above). Telenor India's operations will continue as normal, until the transaction is completed by the end of 2017.

Data options
Data packages differ between circles and are given here for 2G data: change circle on top right.

In 2017 4G/LTE on 1800 MHz is active in the cities of Vizag, Vijayawada, Eluru, Tenali, Bhimavaram, Warangal, Guntur, Cuddapa, Rajahmundry, Karimnagar and Hyderabad. 4G data plans for prepaid differ again between circles and can be checked here: change circle on top right. While placing a call, Telenor network shifts from 4G to 2G. Given the network quality and presence in only 7 circles as of today, Telenor poses no significant threat to any of the incumbents. But after the Airtel-Telenor deal is completed, Telenor plans will be closely watched by every user. Airtel-Telenor combine will try to retain existing customers with its attractive plans.
 * Telenor’s two new plans of Rs 116 and Rs 146 are giving a tough fight to Reliance Jio and other operators. Seeing the growing demand for unlimited data, Telenor has launched two 1 GB 4G data per day packs. One is priced at Rs 116, and the other one is priced at Rs 146. Both packs offer unlimited Telenor to Telenor calling. However, to enjoy voice calling to another network, users have to recharge with the Rs 146 plan because of the Rs 116 plan offers just Telenor to Telenor calling. Also, for the Rs.146 prepaid plan, calls to other networks are capped at 400 mins. The Rs.116 pack lacks free intra-operator calling.n Both the packs lack free SMS and free roaming.
