Claro Costa Rica and travel eSIM in Costa Rica
Claro Costa Rica is one of the networks your eSIM may use in Costa Rica. Here is who actually decides which network you get, and what to do with that.

Quick answer
- 36 of the 36 Costa Rica plans we sell name Claro Costa Rica as a reachable network, at 4G and 5G.
- Claro runs LTE on B3 and 5G on n78; your phone needs at least one of them.
- Travel plans connect by roaming, so no plan can promise one specific network.
Claro Costa Rica in brief
Claro Costa Rica runs a commercial 5G network with its own 5G coverage map, and its 5G spectrum includes 100 MHz in the 3,500 MHz band.
We are not a reseller for this operator and we have not run our own field speed tests. The band and network details below come from the sources listed at the end of the page.
Claro's bands and technology
| Item | Claro |
|---|---|
| LTE (4G) | B3 |
| 5G NR | n78 |
| 5G launched | Live |
| Network code (MCC-MNC) | 712-03 |
Checked against the sources on 2026-10-12. Only the bands a source confirmed are listed; the network may run others too.
An eSIM can only use Claro if your phone supports at least one band in this table. Before you fly, open your model's spec page on the maker's site and compare its LTE and 5G band lists.
Claro's coverage map
Claro publishes its own coverage map. Look up the street or district you will stay in rather than the country as a whole, because coverage in town and out of town differs a great deal. The map shows Claro's own network; a roaming plan may not get every technology it shows.
Who licenses Claro
Mobile networks in Costa Rica are licensed, and their spectrum assigned, by the Superintendencia de Telecomunicaciones (SUTEL). The bands above are the ones it allocates. A problem with the local network's own service goes to the operator first; a problem with your eSIM plan comes to us.
The plans on our shelf that name Claro Costa Rica
From the supplier record behind each package, 36 of the 36 plans we currently sell for Costa Rica declare Claro Costa Rica as a network the profile can reach, at 4G and 5G. The figure comes from the same catalogue that prices the plan pages, and it moves when the supplier revises the record.
A plan naming Claro Costa Rica means the network sits in the list the profile may choose from. It does not mean your handset will stay on it. The priority order is the supplier's, and the signal where you stand decides.
Why plans do not name a fixed network
Nearly every travel eSIM is a roaming product: the profile picks a network by an order the supplier sets, not by the buyer. If Claro Costa Rica is weak where you are, try selecting Kölbi (ICE) or Liberty Costa Rica manually in the network settings, and keep data roaming on for the eSIM profile.
FAQ
Will my eSIM definitely connect to Claro Costa Rica?+
36 of our plans name Claro Costa Rica as reachable, but that is not a guarantee. Travel plans run over roaming agreements, so the network depends on the supplier behind the plan, your device and where you are.
Which bands does my phone need for Claro?+
At least one of these, LTE: B3; 5G: n78. Your phone's band list is on the maker's spec page for your model, under "Cellular" or "Network".
Does Claro Costa Rica run 5G, and will my plan get it?+
Yes. Claro has run commercial 5G, on n78. A travel plan only gets it when the plan permits 5G, your phone supports one of those bands, and you are inside 5G coverage. Miss any one and you fall back to 4G.
How do I see which network I am on?+
Check the carrier name at the top of the screen, or open the mobile-network settings and look at the operator list. If signal is poor, try selecting a network manually instead of automatic, but only one your plan actually supports.
