Portugal

Basics
Portugal (including the Azores and Madeira Islands) has three network providers operating in the country: MEO is market leader with the best coverage in the country, followed by Vodafone in 2nd spot and NOS as smallest network.
 * MEO (formerly tmn)
 * Vodafone (formerly telecel)
 * NOS (formerly Optimus)

2G is on 900 and 1800 MHz, 3G is on 2100 MHz with MEO and NOS and on 900 MHz with Vodafone. 4G/LTE was launched in 2012 on all three networks on the 800, 1800 and 2600 MHz bands. It already reaches the majority of population and is open for prepaid on all network providers.

All three networks are available too in the Portugese branches of The Phone House: store locator and Worten.

Top-ups can be made in every Payshop agency: store locator. Worten does top-ups as well (at least MEO deducts 0.60 € from the top-up, even if done in MEO stores). Minimum top-up is 5 € every 6 months (3 months with Lycamobile).

Portuguese SIM cards don't need to be registered. In the last years the prices for data have dropped considerably in the country. Portugal is part of the EU, where from June 2017 new international roaming rules are enforced. In most European countries you can now 'roam like at home' at domestic rates rather than excessive roaming rates. Portuguese operators seem to implement the regulation mostly without restrictions, but may only cap large data packages. For specifics about the new rules check the European Union chapter and every provider below.

MEO (formerly tmn)


MEO, called "tmn" not so long ago and now owned by Dutch Altice Group, has the best coverage incl. 4G/LTE in the country: MEO coverage map and it gives it out to prepaid costumers without a surcharge. It is market leader with a 40% share. MEO implements Roam like home on most plans without restrictions.

Availability
The SIM card is available from MEO stores (store locators) or Phone House (see above) for 9.99 €. You can even order it online for free, but you have to send it to a Portuguese postal address. It includes 5 € for calls to other MEO lines, but not for data.

The sell different tariff lines called "Top", "Start", "Link" and "Flex", but that doesn't matter which base product you are on as the data packages are all the same.

Top-ups can be made in many shops e.g. Payshop that has many agencies in Portugal (see Basics).

Data feature packs
MEO offers these monthly data packs open for 4G/LTE in Portugal and the EU/EEA: Subscribe by texting the name of package to 12399. If you activate the LIGHT plan for the first time, 2 GB will be given to you as a free bonus on top of the regular 200 MB in an ongoing promotion. These packs recur every month and it is possible to go into negative credit, which will cause the internet to stop until a positive credit is reached again (even if an add-on is still valid).
 * 200 MB: 5.49 €
 * 500 MB: 7.49 €
 * 2 GB: 12.99 €
 * 6 GB: 21.49 €
 * 15 GB: 30.99 €

You can check your data consumption and allowance anytime on your personal account. To query credit, call *#123*, this should return the "universal" credit that can be used for any calls and data plus the "extra" credit that is only valid for calls to MEO and fixed lines; the online credit information does not distinguish between the two, so is practically useless. The online usage information is not always recent (and in the case of add-on data might not even appear), so another way to query it is by calling this number (a message will come back): *#123*99#

The following add-ons called "plafond adicionais" can be booked on existing packs for more data, valid for 30 days: To add volume, text EXTRA 200MB, EXTRA 1GB, EXTRA 5GB or EXTRA 15GB to 12399.
 * 200 MB: € 3.99
 * 1 GB: € 7.99
 * 5 GB: € 16.49
 * 15 GB: € 26.99

After pack data runs out (at least for the Start SIM card) it reverts to default rate of 1.99 € for 60 MB per day. Beware: the pack data runs out silently. SMS sent to inform you might be delayed and the online information of remaining data is not real-time either.

Combo plans
Their combo plan is called TOP and contain a fixed domestic voice call, text and data quota. It's based on a weekly rate. That's why it can be the better alternative for visitors. You have to set your SIM to TOP plan from the beginning. It comes in two varieties for voice and texts: Both options can be added by these data packages valid for one week: This way you get cheaper prices for a weekly usage, but without the chance to upsize.
 * TOP 96: unlimited domestic calls to MEO and landlines included plus 100 mins/SMS to other networks for one week
 * TOP TOTAL: 500 mins/SMS to all networks included for one week
 * 200 MB: 2.80 €
 * 1 GB: 3.30 €
 * 3 GB: 4 €

Tourist SIM
MEO has introduced the Connected Holidays plans for tourists visiting Portugal for the summer season 2016 in two plans: Both plans can only be topped up with 30 GB for another 15 days at 15 €. They are available only in a few MEO stores mentioned here (in the middle of the page).
 * Connected Holidays Smartphone: 60 mins voice, 500 SMS and 2 GB mobile internet for 15 €, valid for 15 days. Calls/SMS are domestic, to the EU, US, Canada, Angola, Brazil and Israel.
 * Connected Holidays Data: SIM card costs 15 €, also valid for 15 days, and includes 15 GB (in promotions 30 GB) mobile data.

Data-only SIM
For modems and tablets, MEO has released new data-only SIM cards without voice called "Enjoy" at 15 € loaded with 15 GB (in promotions 30 GB) valid for 15 days. There is a FUP of 3.5 for EU roaming. [update/note: your contributor's MEO Enjoy SIM bought September 2017 could not roam in Spain, is not even locking on any network, could someone please verify this is the norm.]

The "Enjoy" plans are topped up like this: for each 10 € top-up you are given 20 GB valid for 5 more days up to a max. of 36 days. Minimum top-up is 10 €. Billing increments is in 100 Kb units. Data will be shut off, if depleted or time has run out.

For Enjoy and Connected Holidays Data MEO states 30 GB data volume on their website, but some shops are reported to sell only 15 GB for a start. Try to print out the offer and show it in the shop.
