Cambodia

Basics
The number of providers in Camboda decreased in the last years from 10 to 5: Three more operators are not anymore on the list, as Excell ran an incompatible CDMA network and closed down in 2015, Cootel is on 2G and WiFi only and Cambodian Beeline was sold to Metfone in 2015.
 * Metfone (by Viettel)
 * Smart (by Axiata)
 * Cellcard (by Mobitel)
 * qb
 * Seatel (4G/LTE only)

2G/GSM is on 900 and 1800 MHz, 3G on 2100 MHz and 4G/LTE has started on Metfone, Smart and Cellcard so far on 1800 MHz and Seatel started with LTE in 17 provices in 2015 on 850 MHz.

Up to a few years ago, tourists were not allowed to buy prepaid SIM cards but only at special and overpriced tourist rates. In 2006 the governement even prohibited the deployment of 3G networks to prevent the distribution of "offensive" contents.

These times are gone and today Cambodia has a very competitive market with many operators, quite low rates, a pretty good coverage and fast speeds mainly in the cities. Each operator has different levels of coverage around the country (although all work well in Phnom Penh and Siem Reap) and differently priced packages. To complicate matters, making cross-network calls can be expensive and difficult, which is why you’ll often see Cambodians with three or even four cellphones in hand, which is considered to be cool.

Buying a SIM card
You can buy SIM cards at any of the phone shops in Cambodia, but it’s best to get them directly from the mobile provider. Carriers are required to keep a copy of your passport on file, but many of the small shops don’t bother with this requirement, but you risk being shut off. Additionally, phone shops charge a large surcharge on SIM cards; ones that will cost $1-2 at the carrier office can be up to $10 at a shop.

To purchase a SIM card, you need officially bring a passport with a valid visa to the office. You’ll be offered a variety of cards starting at around $1 only. More expensive cards don’t actually have more value, just supposedly lucky combinations of digits in the phone number. Top-ups can be made at lot of street vendors all around the country.

In 2015 the governement tried to crack down on retailers who are still selling SIM cards without the required IDs. But major telecom companies have done little to curtail the practice: Smart continues to offer free SIM cards to passengers on flights bound for Cambodia, while Metfone advertises free SIMs to arriving passengers at the country’s international airports.

In 2016 the regulator has decided that all unregistered SIM cards in Cambodia will be deactivated by November 2016. Service providers are required to alert users with unregistered SIM cards "seven times within seven days" according to the regulator. If no action is taken, "there must be a full suspension" by 1st of November. This SIM deactivation measure could affect nearly 10% of Cambodia's SIM cards or 2 million phone users that haven't registered their SIM cards yet

Metfone
Metfone is the market leader right now in Cambodia with about 1/2 of all customers after they acquired Beeline in 2015. It's backed by Vietnamese Viettel group and is said to have the best coverage outside of major towns in the provinces, even if they don't provide a map.

4G/LTE started in summer 2016 on 1800 MHz and Metfone claims LTE coverage in 90% of urban areas in Cambodia already..

The latter line is often offered to tourists, but all need the same data packages. For 4G/LTE you need a new 4G-enabled SIM card. Old 3G SIM cards can be changed for free in their stores.
