Ask 10 travelers about their experiences using data on their phones while abroad and you’ll likely get at least a few horror stories. Trying to stay connected on your wireless devices can be a frustrating experience. The stories of people getting billed outrageous amounts from their cell phone carrier are so common that you probably know someone personally who has gotten a nasty surprise. It only takes getting burned once by international roaming charges to make you want to avoid that pain in the future.
Americans and Canadians pay among the highest roaming fees in the world, often facing significantly steeper costs than travelers from other countries when using mobile data abroad. Research shows that over 80 percent of American travelers report confusion about mobile roaming charges when going abroad, which frequently leads to unexpected bills and unnecessary stress.
Your phone continues using data in the background even when you’re not actively browsing. Email sync, app updates, and cloud backups can trigger roaming charges without your knowledge unless you’ve carefully turned all these off in your settings, leading to bill shock when you return home.
T-Mobile has been the most progressive carrier in moving away from these international roaming charges, including international data and texts in their regular rates with most plans. (You pay 25 cents per minute for a call, but nothing if you’re on Wi-Fi.) If you’re in Mexico, you can call, text, and surf the web just like you do in the USA, with no extra charges.
You can still get throttled after a while with them though if you use more than 5GB in a month while traveling. In some countries, like Argentina, you may be on a very slow network they have partnered with. I had trouble using Google Maps there while walking in Buenos Aires because there was so much of a lag.
Thankfully, the advent of eSIM plans has meant that you don’t have to rely on what your home carrier offers when traveling. The best solution for most people is to sign up with one of these companies in advance so you know for sure how much you’ll be paying. It’s usually quite reasonable too. With eSIM Plus for example, you can get 10GB of data for 30 days to cover your vacation in Peru for less than a dollar a day. For Costa Rica it’s only $18 for 10GB.
How International Data Access Works in Practice
Most people who have never used an eSIM before are apprehensive about the process. They think it’ll mess up their phone, that they’ll miss important phone calls, or that they’ll have trouble switching back when they return home.
In reality, there’s so much heavy competition out there in the wireless world that nobody can afford disgruntled customers. So these companies will carefully walk you through the process online and through e-mails and support people are available if you need personalized help.
When you travel internationally, your phone connects to foreign networks through roaming agreements between carriers, triggering charges that can be outrageous if you’re on one of the U.S. or Canadian networks. Travelers from those two countries face particularly steep fees due to market structure and the absence of regulatory price caps that protect consumers in other developed nations.
When you sign up with an eSIM company though, you’re tapping into their agreements with local carriers, which are much more consumer-friendly. They have partnered with local carriers for almost every country in the world. Since this is basically free money for the local carriers, a temporary cash injection, they’re willing to discount the access to their towers.
The advent of non-physical solutions has made it much easier to roam on a local network when traveling. The eSIM technology eliminates physical SIM cards entirely by embedding connectivity directly into your phone’s hardware. You usually receive a QR code via email, scan it with your camera, and you just turn it on in your settings to connect.
Your device can store multiple eSIM profiles simultaneously. This means you keep your American or Canadian number active for calls and texts while a travel eSIM handles data connectivity abroad so you can avoid high international roaming charges. No swapping cards, no lost SIM cards, no hunting for a mobile shop after landing.
Most iPhones from 2018 forward support eSIM, as do Android phones manufactured this decade. The setup only takes a few minutes. While some companies offer unlimited plans for $50 a month and up, it’s more common to buy a set amount of data for 7, 15, or 30 days. You control exactly what you spend upfront since eSIM plans use prepaid pricing—you pay for 5GB, 10GB, or unlimited data packages before your trip starts.
Tips and Tricks to Avoid Data Charge Surprises
Many people are used to having unlimited data at home, so they don’t pay attention to which activities are using a lot and which aren’t. If you follow this practice while traveling, however, you can end up using 10GB in a few days instead of it lasting a month.
You’ll want to turn off automatic app updates and cloud photo backups before traveling—or make them “only over Wi-Fi” in your phone settings. These background processes drain data quickly, especially on networks where you’re paying per gigabyte. Download maps, playlists, and entertainment content before departure instead of streaming them. Lossless music on Spotify and movies on Netflix can eat up your data allowance quickly. Only stream media and play live video games when you’re on Wi-Fi.
Keep your primary SIM active for two-factor authentication codes sent to your American number. Configure your phone to use the eSIM exclusively for data while your original number handles calls and texts. One side note: I’ve had trouble getting 2FA texts on my phone when my eSIM was on and I was on the hotel Wi-Fi. If you’re not getting your texts, momentarily turn off Wi-Fi to get back on a network, then reconnect to Wi-Fi after.
Purchase eSIM data packages slightly larger than you expect to need. Running out mid-trip means scrambling for Wi-Fi or paying premium rates for emergency top-ups. Most providers let you add data instantly through their app if needed.
Check your data consumption regularly through your phone’s built-level settings if you think you are in danger of running out. You can also set up alerts for when you hit a certain amount of data used, either by gigabytes or by percentage. It’s easy to “top up” for more data though through the eSIM app or their website, but if you’ve completely run out then you need to use Wi-Fi to do it.
While most eSIM plans are data-only, don’t forget that you can make calls over Wi-Fi easily when you’re back in your hotel or rental apartment. Plus you’re using data if you make a video call by Zoom, Google Meet, or Facetime. Once again though, it’s best to do that over Wi-Fi since a video call can use a lot of data.
