Will my phone work in Costa Rica? By Josh Levesque Published July 8, 2025 Your bags are packed, the flight is scheduled, the hotel is booked, you’ve researched all the volcano tours… you’re ready to visit Costa Rica. But when your parents tell you to call them as soon as you land, you stop to ask yourself “Will my phone work in Costa Rica? And how much is it gonna cost me if it does?” These are valid questions, and this blog has the answers. Let’s go over the ins & outs of using your US-based phone on your trip to Costa Rica. In this article Can I use my phone in Costa Rica? The short answer is yes. Virtually all modern smartphones can be used in Costa Rica and are compatible with their wireless network towers. That said, you will need to purchase some form of international roaming to be able to get access to their networks and stay connected. Most U.S. phone carriers offer international roaming add-ons you can purchase before or during your trip for maximum ease. We recommend researching your carrier’s options before you leave to avoid unexpected overages. We’ll also cover your other options below. Most carriers will alert you of the costs of calling, texting and data once you’ve arrived at your destination—because using roaming data can get very expensive, very fast—depending on your carrier’s roaming offering. Nowadays, most U.S. phone carriers offer international roaming options that you can purchase ahead of, or even during, your trip. In fact, some carriers even have international roaming add-ons that you can buy for a very low rate that are super easy to use… we’ll get into that a bit later though. Some travelers prefer to purchase a local SIM card when they arrive at their international destination. Next, we’ll cover how that works and if that’s something you might want to do. Will a Costa Rican SIM card work in a U.S. phone? Costa Rican SIM cards should work in most unlocked U.S. phones. If your phone is unlocked and ready to go, you can buy a prepaid physical SIM card or an eSIM data plan ahead of your trip, or upon arrival. The benefit of using a Costa Rican SIM is that it helps you avoid roaming fees on calling, texts and data usage. Just remember that when using a Costa Rican SIM, people won’t be able to reach you via your regular number. However, if your phone is dual-SIM compatible, you may be able to use a Costa Rican SIM and keep your previous SIM active with your regular number. Also, putting a Costa Rican SIM card in your phone may automatically change the language of the phone’s menus and display. If a Costa Rican SIM card isn’t for you, but you still want the benefit of being able to move from country to country with ease, look into your carrier’s roaming offerings. Check to see what countries are included with your carrier’s international roaming program before you jet off to Central America and beyond. For example, Mint Mobile’s Minternational Pass works wherever you go, so you don’t need a new SIM card when you hop between countries. Just, ya know, throwing that option out there. Tips for using U.S. cell phones in Costa Rica If you’re still undecided about the route you want to go, here are some general tips for using your phone in Costa Rica. A little pre-planning can help you minimize your data use throughout your journey. Connect to Wi-Fi when you can: Luckily these days, there’s free Wi-Fi available in tons of pubs, cafes and restaurants. Take advantage of Wi-Fi where you find it to help minimize data usage. Since Wi-Fi is often available in spots catering to tourists, there may be added risks of identity theft or hacking – make sure to follow best practices when it comes to phone network security and try to connect to secure networks whenever possible. Utilize airplane mode: As a general guideline, we recommend putting your phone on airplane mode as the default setting on your travels to avoid accidental data usage. Even if you have airplane mode on, you can still connect to Wi-Fi and use any other phone functions that don’t require cellular data. Download content for offline use: When you’re able to get a Wi-Fi connection, take the opportunity to download maps, guidebooks, and media that you can use later without eating into your data, and avoid additional roaming charges. Use Wi-Fi Calling: Most phone plans include Wi-Fi Calling as a feature (including Mint) and it’s pretty nifty. Wi-Fi Calling lets you make calls while connected to Wi-Fi at no additional cost, and can be easily turned on in your phone’s settings. Pause auto downloads and background app refresh: Make sure things like push notifications, auto updates and things like that are turned off while you’re abroad. It may seem like just a notification here and there, but in reality, these can slowly but surely chip away at your data – and no one wants that. Head here for a refreshmint on background app refresh.
