That’s why you’ll want a prepaid SIM card for your time the country. Prepaid SIM cards offer significantly better performance, and are much more affordable, saving you hundreds if not thousands in data charges. Here are a few of our favorite picks.

ThreeUK Smart Silver

Coming up first, we are looking at a fan-favorite — the Smart Silver prepaid SIM card from ThreeUK is one of the best ways that you can go for a SIM card in Costa Rica.

ThreeUK makes it very easy to activate your Smart Silver card when in Costra Rica. Slide the card into your SIM tray, power on your phone, and then it’s immediately activated and ready for use.

That said, the SIM card only lasts for 30 days upon activation. Once that 30 days is up, the SIM card expires. So, if you have a long trip planned, you’ll want to wait until you’re in the country to activate to make the most out of the time that you have.

Additionally, the Smart Silver card has 5GB of data that you can use while in Costa Rica. There are no refill options, so once that 5GB is used up, you’ll need a new SIM card.

That said, the card expires when you use that 5GB up or that 30 days passes, whichever comes first.

ThreeUK’s Smart Silver doesn’t have any outgoing calling or texting abilities, but the card does say that you can at least receive incoming calls and texts.

Get it here.

KeepGo Global Lifetime

If you’re looking to get 4G LTE data while in Costa Rica, you’ll want to look no further than the KeepGo Global Lifetime SIM card. With your purchase you get a whole 1GB of data to use in the country, but then are charged per 1GB that you use.

KeepGo is designed be one SIM card that works in every country that you go to. So, if you plan on traveling from country to country on your trip, KeepGo is one of the few that can keep an active cellular connection running for you.

This is a data-only SIM, and will not offer you and incoming or outgoing calling abilities.

Local Carriers

You actually might want to consider picking up your prepaid SIM card from a local carrier in Costa Rica. That’s because you’re almost always going to save the most money, while getting the fastest speeds this way.

Once you land in Costa Rica, you’ll have plenty of opportunity to purchase a SIM down there — you usually don’t have to go anywhere out of your way. That’s because you can pick them up from right in the airport to local stand up shops. A lot of retailers have them available for tourists, too.

One of the added bonuses to this process is that you aren’t going to have to pay much by picking up a local, prepaid SIM card in Costa Rica. You really aren’t going to pay much more than $20 to $30 in US dollars.

T-Mobile Postpaid Plans

Like we mentioned earlier, carriers back home can have some fairly expensive rates — but just one carrier that offers you excellent performance and affordability for international travel is T-Mobile.

If you’re on a T-Mobile postpaid plan — specifically T-Mobile ONE or Simple Choice — you will have no problem using data, text, and talk time in Costa Rica.

They really do  have your back here — that’s because T-Mobile actually supports well over 200 countries, so long as you’re on one of the aforementioned plans.

They will first and foremost provide you with unlimited data while in the country. Speed highly depends on where you’re at in Costa Rica, but they do give you unlimited texts as well. Talk time costs a little bit extra, at $0.25 per minute, though that can be averted by using Facebook Messenger calls or similar platforms.


As usual for countries south of the US, there aren’t many SIM card options that will work in South or Central America. That’s largely due to poor infrastructure; however, that does mean that a SIM card from a local carrier will almost always perform better.
