Not long ago, a man from the U.S. returned home from a trip to Europe to a $143,000 T-Mobile bill, apparently because the phone had not been set up for international roaming, according to an article in The Guardian. Considering that 1.3 billion people traveled globally in 2023, there’s a real chance you, too, may come home to a high cell phone bill, especially if you don't determine your needs (or wants) beforehand.
Although using your smartphone has become a necessary part of international travel, roaming fees alone can be exorbitant, and depending on your carrier, using data outside the U.S. is also at a premium.
What is the right way to set up your phone when traveling internationally? Here are five tips.
1. Before you travel, talk to your provider
The first thing to do before traveling overseas is to check out your service provider’s policy regarding international cell phone use. Although you may want to reach out a few months before traveling, check back often, as policies can change. You may also want to see what your current contract does and doesn’t allow.
In the past, global roaming was an extra feature you could opt into for an additional fee. However, many service providers now activate international texting, calling and data features automatically as soon as you use your phone in a foreign country. Just understand that this feature can be pricey, so if you plan on traveling for a long time, find out ahead of time if it’s worth the price.
2. Use temporary data passes
When traveling abroad, you may find you need extra data because you want a higher data speed, the ability to stream HD video, or you’ve reached your data allotment. Providers like T-Mobile, Verizon and AT&T all provide temporary data passes — although they have different names — that each provide a set amount of roaming data that you can use for a certain amount of time for one price.
Unfortunately, these temporary data passes are expensive. Verizon, for instance, recently raised its daily price from $10 to $12. But if you can’t unlock your phone, these are a good option.
T-Mobile's International Pass gives you:
- $5 for 24 hours of unlimited calling and 512MB of high-speed international data
- $35 for 10 days of unlimited calling and 5GB of high-speed international data
- $50 for 30 days of unlimited calling and 15GB of high-speed international data
Verizon’s TravelPass gives you:
- $12 per day unlimited calls, data and texts
- $6 per day for the same in Mexico and Canada
AT&T’s International Day Pass gives you:
- $12 per day unlimited data, talk and text
- $6 for each additional line
3. Swap your SIM card
Renting a SIM card allows you to make calls or text and use data by swapping out your current SIM card for one compatible with the country you're visiting. When you rent a new SIM card, you’ll get a new number, so you won’t be able to receive calls or texts on your regular phone number.
Before you go, make sure to notify family and friends so they can contact you via a chat app like WhatsApp or Facebook Messenger instead. Even so, renting a card is generally a much cheaper option than paying for an international roaming service.
Specialized stores in major airports and cell phone companies often offer SIM card rental. In fact, Amazon sells SIM cards for Europe ranging from around $20-$50, typically for 30 days of use.
You should make sure you can change your phone's SIM card and that you know how to do it before you take this route. Note that it is possible to change SIM cards on iPhones, but if you have an iPhone 14 or later model, you'll need to use an eSIM card.
Unlike the regular SIM cards you remove from a phone, an eSIM is a microchip embedded in the phone’s hardware and is especially useful when you’re traveling internationally. According to AARP, you can purchase data through eSIM providers such as GigSky, Airalo, Nomad and Flexiroam, or you can add an eSIM from a local provider in the country you’re visiting.
4. Get an international phone
If you think you will make many calls or use your phone extensively while visiting another country, consider purchasing an international phone. These international mobile phones often come with reduced international roaming rates and data.
You can try doing this when you arrive at your destination, just be aware of language barriers and have an idea of what you're looking for before you get to a store.
5. Use Wi-Fi and certain phone settings instead of data
Besides getting a temporary international pass or swapping your SIM card, you can also use Wi-Fi and certain download options on your phone and apps. In many cases, you don't even need data at all to do what you want to do, you just need Wi-Fi.
Using free Wi-Fi and otherwise turning off cell service is Kiplinger digital managing editor Alexandra Svokos' preferred method for traveling.
"I have an iPhone, and iMessage and FaceTime only need Wi-Fi to work, so I set my phone to 'airplane' mode, text or FaceTime my family to keep in touch when I'm at the hotel with Wi-Fi, and then I'll go out and be in the moment when I'm visiting sites," she said.
Here are some useful tips:
- Turn off data roaming in your phone’s settings when you don’t need it.
- Download maps of whole cities or regions on Google Maps for use when you don't have data or Wi-Fi. This is also useful if you're traveling somewhere with poor service, even in the U.S.
- Similarly, if you use an app like AllTrails for hikes, you can get AllTrails+ for $36 a year, and then you're able to download maps to navigate when you're offline or away from data.
- Shut off all non-vital apps. When apps automatically update, you are charged if they are still active.
- Deactivate texting. This stops texts from being billed as data when you're traveling aboard.
Just remember to have an emergency plan, Svokos said.
"I try to use paid international cell service as little as possible, but I'm also comfortable doing that because I know if I'm in a crunch and need service, I can just turn off 'airplane' mode and my Verizon plan will automatically give me 24 hours of international service for $12," she said. "It also becomes a sort of game with myself to see how few days I actually need to have data, versus just using free Wi-Fi."
