Bottom line: Costa Rica is an unusually easy country to arrive in and an unusually easy one to get connected in — but the two rules that decide your trip are administrative, not technical. Since the immigration service published revised general entry guidelines on 17 November 2025, visa-exempt (Group 1) nationalities may be admitted for up to 180 days, though the officer at the desk sets the actual figure and can grant less. On the connectivity side, every prepaid line in Costa Rica must be registered with the regulator SUTEL against an identity document; a passport is accepted, and the cap is five prepaid lines per passport. That registration step is exactly what an international travel eSIM lets you skip, which is why it is the sensible default for a trip of two or three weeks. The network itself is dense — mobile internet penetration reached 106% of the population in 2025, up from 95% in 2021, and 5G is live — but it is not flawless: we measured a 2.5-hour national connectivity disruption on 31 July 2026.
This page is built from primary sources — the Dirección General de Migración y Extranjería, the Superintendencia de Telecomunicaciones, the Instituto Costarricense de Turismo, the GSMA specification your handset implements, and a live outage dataset we queried ourselves — rather than from other travel blogs. Every figure carries its date.
Entry: 180 days is a ceiling, not an entitlement
Costa Rica’s immigration authority, the Dirección General de Migración y Extranjería (DGME), sorts nationalities into visa groups. Group 1 — which covers the United States, Canada, the United Kingdom, most of the European Union, Japan, South Korea, Australia, New Zealand, Argentina, Brazil, Chile, Mexico and others — enters without a visa. Under the general entry and stay guidelines published on 17 November 2025 and reported at the time, the maximum admitted stay for that group is 180 days.
The part travellers misread is that 180 is a maximum the officer may grant, not a number you are owed. In practice the stamp you receive is influenced by:
- Your onward ticket. Proof that you will leave within the permitted period is a documented entry condition. An open-ended itinerary invites a shorter stamp.
- Your travel history. Back-to-back long stays with brief exits are recognised for what they are, and are the most common reason a returning visitor is given 30 or 60 days instead of 180.
- Evidence of funds and of somewhere to stay. Rarely asked for, occasionally decisive.
Two practical consequences for connectivity. First, everything above lives on your phone — booking references, onward flight, accommodation confirmation — and the immigration desk is before the arrivals-hall SIM counter, not after it. Second, overstaying carries fines and re-entry consequences, so knowing exactly what date you were stamped to matters; photograph the stamp on arrival while you still remember to. The Instituto Costarricense de Turismo is the official reference for general visitor information alongside DGME.
Why a local prepaid SIM costs you a queue, and an eSIM does not
Costa Rica requires prepaid mobile lines to be registered against an identity document, under rules administered by the telecoms regulator, the Superintendencia de Telecomunicaciones (SUTEL). For a foreign visitor this is not a barrier — a passport is an accepted document — but it is a process:
- You register in person, with the physical passport, at an operator shop or an airport counter.
- A single passport can hold a maximum of five prepaid lines. Irrelevant to most visitors, decisive for anyone travelling with a stack of devices.
- The three national operators are Kölbi (the mobile brand of the state utility ICE), Claro and Liberty — the last being the former Movistar operation, acquired by Liberty Latin America in August 2021.
An international travel eSIM sidesteps that entirely: the profile is issued by a foreign provider and roams onto a Costa Rican network, so there is no local registration, no counter and no passport photocopy. That is the whole of the advantage, and it is worth being precise about it — it is a convenience advantage, not a coverage or price advantage. A local prepaid line is usually cheaper per gigabyte and gives you a Costa Rican number for domestic calls and SMS verification. The crossover comes somewhere around three weeks; below that, the queue costs more than the savings.
What the network is actually like
Costa Rica is a genuinely well-connected small country. SUTEL’s 2025 sector statistics, summarised by the telecoms trade press in May 2026, show mobile internet penetration at 106% of the population in 2025 — more active mobile data subscriptions than people — against 95% in 2021, with mobile telephony penetration steady around 137%. National fibre grew from about 66,000 km in 2021 to more than 129,000 km in 2025, and the sector took ₡804,950 million in revenue, up 4.9% year on year. The market splits three ways and the leadership depends which metric you pick: Kölbi (ICE) takes about 43% of sector revenue, Liberty holds about 40% of total subscriptions, and Claro about 17%. Liberty is furthest ahead on 5G standalone deployment. A useful side-note for a visitor: postpaid subscriptions grew 15.4% in 2025 while prepaid fell 11%, so the prepaid tourist product is a shrinking part of these operators’ business, not a growing one.
What that means on the ground: San José, the Central Valley, Liberia, Tamarindo, Jacó, Manuel Antonio and the main Guanacaste and Pacific resort corridors are comfortable, often with 5G. The gaps are exactly where you would expect them in a country whose selling point is wilderness — the Osa Peninsula, Corcovado, Tortuguero, the Talamanca highlands and much of the Caribbean south. Plan for those stretches deliberately rather than discovering them.
What we measured: Costa Rican connectivity, 27 July – 26 August 2026
Penetration statistics describe capacity. They say nothing about whether the network stayed up. We queried the Internet Outage Detection and Analysis (IODA) project at the Georgia Institute of Technology for country-level alerts on Costa Rica across the 30 days ending 26 August 2026. It recorded one event:
| Start (UTC) | Signal | Duration | Level vs baseline |
|---|---|---|---|
| 31 Jul 2026, 01:30 | Aggregated traffic telemetry | ≈ 2 h 30 min | 2,854 vs 3,697 (−22.8%) |
One measurable national disruption in a month, lasting two and a half hours overnight and taking away just under a quarter of observed traffic, is a good result. It is materially quieter than what the same dataset shows for countries with contested or fragile infrastructure. But it is not zero, and 01:30–04:00 local-adjacent hours is precisely when an overnight bus transfer or a pre-dawn departure to a national park happens. The lesson is the dull one: download your maps, your booking references and your onward boarding pass, rather than assuming you can fetch them at 3 a.m.
Choosing, in the order the decisions arrive
- Check your handset supports eSIM at all. Profile download uses the GSMA consumer remote SIM provisioning standard, and the GSMA’s device list is the authority on which models implement it.
- Install the profile before you fly and leave it dormant. Every provider lets you install now and start the validity window on arrival. The point is to have data working at immigration, not after it.
- Size realistically. Costa Rica’s own subscribers use mobile data heavily enough to push penetration past 100%. For a two-week trip with navigation, translation, rain-radar checking and photo uploads, 5–10 GB with a top-up option is a sane range; a 1 GB package is a false economy.
- Add a local prepaid line only if you are staying beyond about three weeks, or if you specifically need a Costa Rican number for domestic SMS verification. Bring the physical passport — a photograph of it will not do for registration.
- Pre-download for the wilderness legs. Corcovado, Tortuguero and the Talamanca highlands are where the coverage map stops being decorative.
If Costa Rica is one stop on a longer Latin American route, the entry rules and network economics differ sharply country by country — compare with Mexico, the Dominican Republic and Peru before assuming a regional plan is the cheapest way to cover them all.

FAQ
Will I definitely be given 180 days on arrival?
No. Under the guidelines published on 17 November 2025, 180 days is the maximum that may be granted to visa-exempt Group 1 nationals. The immigration officer decides the actual figure and may grant less, taking into account your onward ticket date, your travel history and your evidence of funds. Photograph your entry stamp so you know the exact date you must leave by.
Do I need my passport to buy a SIM card in Costa Rica?
Yes. Prepaid lines must be registered against an identity document under SUTEL’s rules, and for a foreign visitor that means the physical passport, presented in person at an operator shop or airport counter. A single passport may hold up to five prepaid lines. A travel eSIM avoids the process entirely because it is issued abroad and roams onto a Costa Rican network.
Is there 5G in Costa Rica?
Yes, with coverage concentrated in San José, the Central Valley and the main tourist corridors, and Liberty furthest ahead on standalone 5G. Liberty also holds the largest share of total subscriptions at about 40%, while Kölbi leads on sector revenue at about 43%. Outside the main corridors expect 4G, and in the remoter national parks and the Osa Peninsula expect stretches with no usable signal at all.
How much data should I buy for two weeks?
Between 5 and 10 GB with the ability to top up covers most itineraries that involve daily navigation, translation, weather checking and photo sharing. Costa Rica’s mobile internet penetration reached 106% of the population in 2025, which tells you local usage is heavy rather than occasional; sizing to a 1 GB starter package tends to end in a rushed top-up in a poor signal area.
Does a travel eSIM give me a Costa Rican phone number?
Usually not — most travel eSIMs are data-only or carry a foreign number. If you need a local number for domestic SMS verification, for a bank or delivery app, or for calling a lodge that does not answer messages, that is the case for adding a registered local prepaid line alongside the eSIM.
Is the network reliable enough to depend on?
Broadly yes. Independent outage measurement recorded a single national disruption in the 30 days to 26 August 2026 — about two and a half hours on 31 July, removing just under a quarter of observed traffic. That is a quiet month by international standards. It is still an argument for downloading maps, tickets and confirmations rather than relying on fetching them at the moment you need them.
