Prepaid Data SIM Card Wiki

Brazil is a world of its own. Very chaotic and not easy to handle for foreigners. Don’t expect anyone to speak or understand English. The state of the service industry and mobile providers in particular are reason for many complaints by locals too. But with a few guidelines, you can make it through the country, though prices for data on prepaid remain high compared to other Latin American countries.

Basics Edit

Operators Edit

There are 4 national operators, that share 97% of the mobile market in Brazil:

  • Vivo (Telefónica Brazil, owned by Spanish Telefónica)
  • TIM (owned by Telecom Italia)
  • Claro (owned by Mexican América Móvil)
  • Oi (Brasil Telecom, incl. Amazônia Celular)

Furthermore, there are some regional providers:

  • Nextel (no prepaid)
  • Algar Telecom (formerly CTBC) in Minas Gerais state
  • Sercomtel in Paraná state

Nextel has an own very limited coverage on 3G and 4G/LTE in some cities on 1800 MHz, but is not mentioned further as they don't offer prepaid plans on the market.

MVNOs have been pretty useless in Brazil. Up to 2015, they cater almost exclusively for M2M companies (for tracking vehicles, portable credit card machines or insurance companies) like the biggest MVNO Porto Seguro Conecta using TIM network. The national regulator ANATEL invented a special scheme in 2014 to facilitate access and in October 2015 the first public MVNO started with Mais AD.

Finally, two companies currently offer 4G/LTE subscriptions only to fixed connections through modems:

  • On Telecom
  • SKY (acquired by AT&T)

Both companies operate on the 2600 MHz band and don’t show intention of extending their services to mobile devices. Services are available only to select regions like some municipalities of the São Paulo state at On Telecom, while SKY is available in DF and certain states of the North, Northeast and South East regions. As they are not for prepaid, they are not mentioned any further.

Regulations Edit

Up to 2012, the mobile market was hardly accessible to foreigners. To get a prepaid SIM card in Brazil, a CPF (Cadastro de Pessoa Fisica) number was required, that corresponds to a tax ID or Social Security Number. Every Brazilian resident has one, but the hurdles of getting one for visitors have been steep.

The government changed rules in 2012 for the upcoming Football World Cup: mobile providers are now supposed to accept passport data from foreigners instead of their CPF. This makes it now much easier to get a local SIM card.

It took a while until the shops realized the new rules, and it still can raise eyebrows when you tell them that you want to get you SIM card without having a CPF (“nao tem CPF”). But most of the employees are familiar with it by now (see Registration below) as long as you show your passport.

Frequencies Edit

Besides GSM in 2G, 3G and 4G/LTE, other systems are in use too, like iDEN and CDMA/EVDO. But they are slowly phased out and stay incompatible to GSM. The mobile industry in Brazil is organized according to regional zones called DDD. The same provider can be on different frequencies according to their licences in the state you are in.

Operator 2G (MHz) 3G/HSDPA (MHz) 4G/LTE (MHz) FDD-LTE
Vivo 850, 1800, (1900§) 850, 2100 2600 (B7), (700*)
TIM 850, 1800 850, 2100 2600 (B7), 1800 (B3)#, (700*)
Claro 850, 1800 850, 2100 2600 (B7), (700*)
Oi 850, 1800 2100 2600 (B7), (700*)

(700*) = The 700 MHz frequency for 4G/LTE will be deployed as soon as analog TV has left this band in 2018 or later.

(1900§): Vivo's 1900 MHz frequency has been realigned to 3G (as uplink for 2100 MHz) in most parts of the country and is used for 2G only in the Northeastern region anymore

1800 (B3)# = TIM's LTE on 1800 MHz (B3) is only avaliable in 4 cities in the interior of Rio de Janeiro, other cities use 2600 MHz (B7).

All operators have now opened 4G/LTE for all of their prepaid plans without surcharges.

Coverage Edit

You have coverage in all states on the 4 major providers Vivo, TIM, Claro and Oi. This is also true to Nextel up to 3G thanks to a roaming agreement. The local providers at the end of the list only have a very limited coverage in their own region and are not recommended for travelling.

The four major players are pretty equal. Vivo is the overall market leader, thanks to a strong post-paid share, TIM and Oi are the pre-paid leaders and Claro leads in the Mobile Broadband section.

As a golden rule: The richer your area is, the better your coverage and speed will be. This applies on a state-wide as well on a local level to all providers. As you know, the gap is huge in Brazil ranging from non-existent to hyper speed. For more infomation, check each provider.

Availability Edit

SIM cards are called chips and cost around R$8 to R$10, sometimes discounted a RS$5 in promotions mostly without credit. You can get it a many locations, but better stick to the mobile provider shops, as they can do or may help with registrations without CPF. There you need to show your passport and give a local address (like hotel address). Try to make clear that you need a prepaid which is called pré-pago (pronounced: pray pah go).

Claro, TIM and Oi sell tourist SIM cards which are not available for local residents. Generally, they give good rates, but have been proven to be hard to find sometimes.

Recharges Edit

You can refill accounts almost everywhere like in operator stores, drugstores, supermarkets, newsstands, convenience stores, post offices or by online agencies like, iCelex and Onepay. Most prepaid SIM cards need to be topped up at least every 60 days to stay alive.

Registration Edit

While newsstand and street sellers offer SIM cards too, you'd better go to an official store, if you don’t have a CPF. Otherwise, you need to contact the operators special service for non-Brazilian residents, which require to give passport data, a local address (can be your hotel), and a local phone number in order to activate over the phone.

The regular registration with CPF is shown HERE. During the registration process you can select your telephone region called DDD, which the card number will be assigned to like in the US. It does not make any difference for data, but a huge one for voice rates. Generally, you should select the region where you are going to use it most, if you want to make domestic voice calls (see voice plans).

Some SIM cards come preloaded with credit which can be checked by the user by calling a specific number provided by the operator from which a SMS message is sent showing the total credits available for that card. These numbers are: Vivo: *8000 Claro: *544#  TIM: *222# and Oi: *804

Voice Rates Edit

While all data allowances are the same nationwide, voice rates differ enormously. That’s why most Brazilians have more than one SIM card and often dual-SIM phones.

Generally, calls are very cheap as long as you stay within the same network and the same area code called DDD (around R$0.25 per call). Long-distance domestic cellular calls remain cheap if you use the prefix of your provider and stay within the same network (see dialing rules).  Local landline calls mostly stay reasonable (at around R$0.70 per call), but get quite expensive outside of your prefix area.

On the other hand all calls between networks, even local, and landline calls to other regions are very expensive (at around R$2 per min). For long distance calls, special dialing rules apply (see below). Furthermore, you will face incoming roaming charges for being called from outside of your DDD area within Brazil.

Update: In an effort to curb multi-SIM use, TIM and Oi have stopped charging differential tariffs for calls to other operators for all its plans in November 2015.

Rates differ from state to state about 10% because of different taxation. Some providers offer special rates for rural areas. Due to the steep price differences between voice tariffs, you should be aware of two basic guidelines for voice calls (except on TIM and Oi):

  • get you SIM card (assigned to) the region (DDD), where you are going to use it most
  • use the same provider, if you are going to make a lot of calls to one particular mobile number

Dialing rules (long-distance and international) Edit

The Brazilian system for long-distance and international dialing is relatively unusual and somewhat confusing, insofar as the choice of the carrier determines the actual sequence to be dialed.

To dial a long-distance number within Brazil, one needs to use a carrier selection code to choose which long-distance carrier will be used. The carrier selection code is specified before the area code; so, to actually place a call, one should dial 0-xx-aa-nnnn-nnnn, where xx is the two-digit carrier selection code, aa the area (= DDD) code and nnnn-nnnn the local number.

This is true to international calls as well. The sequence is 00-xx-cc-aa-nnnn-nnnn where cc stands for the country code. More info about dialing rules HERE. The carrier selection codes are given in the respective section of each operator.

Technical Details Edit

Tethering is allowed and possible on all plans, as well as VoIP calls. Operators sometimes don’t allow their prepaid voice & data SIM cards to be used in a modem or tablet. But it works anyway and the same rates are charged for Mobile Broadband plans.

There are some areas where service suddenly drops or slows down due to congestion. When you are unsatisfied with the service in your area, there is not much hope in complaining. Better get a new SIM of a competitor instead. When shopping around, always ask about promotions.

Vivo Edit


Vivo is largest mobile operator in Brazil that is owned by Telefónica from Spain and has 29% of the Brazilian market share. From their total of 79 million subscribers only 67% are using prepaid plans. It was the last operator to allow prepaid customers on 4G/LTE in 2015.

Mais AD Edit

Mais AD

Mais AD is Brazil's first real MVNO. It started operations in October 2015 on the Vivo network in 2G, 3G and 4G/LTE (see Vivo above). It is run by the Brazilian arm of the Assembly of God, the country's biggest Pentecostal church with 23 million members.

Availability Edit

The operator is recruiting volunteer assembly members to sell the SIM cards door to door and pastors are promoting them during services. In addition there are 45 physical sales points (list). They have national coverage in all states, but have started their marketing in the state of Sao Paulo only. Start-up price is R$ 9.90 without any credit.

Their SIM card will come with exclusive content related to the Assembly of God and the bible as well as religious apps. To top up, you can use any Vivo voucher. To check credit, type *2300.

Rates Edit

They sell the exactly same prepaid rates as Vivo (see above). So there is not much advantage, in choosing them instead of their network operator, as it is not clear whether Mais AD can handle registrations without a Brazilian CPF.
