Telco providers in Puerto Rico

The island is a US territory and has three main phone operators that are also available in the US: AT&T, T-Mobile and Sprint. Two more operators cover Puerto Rico and the US Virgin Islands but won’t operate on the US mainland: Claro and Open Mobile. All operators have been tried and tested by both the locals and international travellers, and they can be trusted. According to OpenSignal, coverage is great along the shoreline and the main towns and cities, although it could get worse in some areas farther inland.

Open Mobile

Open Mobile is a small provider only available in Puerto Rico. It offers customers 2G, 3G and 4G/LTE services. Prepaid SIM cards can be purchased from official stores and approved resellers. Verizon has a roaming agreement with Open Mobile, so if you already have a Verizon SIM card, then you will be able to use that in Puerto Rico to roam on the Open Mobile network.

Open Mobile calls its own prepaid SIM card packages “Ola”. 2G and 3G plans are based on the CDMA platform, which means GSM phones won’t be able to use it. However, 4G/LTE SIM cards are compatible with GSM international phones. Credit can be purchased in several different denominations between $5 and $250.

The following monthly data plans are available on 4G/LTE SIM cards:


Data credit can be added in the following denominations: $10 for 1GB, $25 for 3GB or $35 for 5GB

T-Mobile’s APN:, and website:


Sprint is the smallest operator but has some good deals available. It offers 2G, 3G and 4G/LTE services. Prepaid SIM cards can be purchased from official stores and approved resellers, and credit can be purchased from the same retailers and most supermarkets. The only catch here, though, is that you must buy a prepaid SIM card pack, which comes with a smartphone. Prices vary depending on which phone you select, but this makes these SIM card packages extremely expensive. We therefore suggest you choose one of the other providers mentioned, as they offer better services and better deals. However, if you do find a better deal on this network, then go ahead and use it because it can be trusted.

Some top tips from staff:

  • Locals call a SIM card a “card” or “SIM”.
  • Ask the retailers to help set up the SIM card for you. They are official sellers and will be very happy to help.
  • Try to get to the stores early to beat the crowds.

  • Prepaid credit when required
  • No in-store contract needed
