5 Best Ways to Use Your Phone When Traveling Abroad

For some, the thought of disconnecting to go on an international trip may seem like a dream, but that idea might be a nightmare for others.

For better or for worse, we live in an ultra-connected world. But on the bright side for those who want to stay connected, there's no shortage of ways to send and receive text messages, calls and overseas.

Some are even free — or at least cheap. Whether it's tapping into an international cell phone plans, getting a local SIM or eSIM card, or maximizing the free-Wifi, here are NerdWallet's tips on the best ways to use your cell phone while abroad:

1. Sign up for the right international phone plan

When it comes to the best international phone plans, a few stand out: Google Fi and T-Mobile. Here's a look at the benefits and drawbacks of each of their international plans:

Google Fi

Google Fi is a virtual cell phone service provider. Rather than owning its own towers, Google Fi partners with local cell phone providers to provide cell, data and text services. And Google Fi didn't just stop at partnering with U.S. cell phone providers. Google Fi provides service in over 200 countries, making it incredibly convenient for frequent international travelers.

How to use Google Fi: Upon landing in an international country, simply turn off airplane mode and use your phone just like you do at home.

With Google Fi service, you'll get unlimited free texting. Meanwhile, data costs the same as when you're back home and actually using Google Fi.

Drawbacks: Phone calls cost extra, and they can add up. Expect to owe 20 cents per minute when calling overseas or traveling overseas on a Google Fi plan.

Another Google Fi drawback? Depending on the plan you choose, data prices can be quite high compared to other cell phone service options while you're in the U.S. So while it's an affordable international pick, it might not net out so affordable back at home.

T-Mobile

You can't say Google Fi without saying T-Mobile. That's because Google Fi actually uses the T-Mobile network.

And you might actually be better off just using T-Mobile directly, as their service is among the best for international travelers. That's because T-Mobile offers unlimited data and texting in more than 215 countries & destinations on qualifying plans.

T-Mobile customers on Go5G Plus, Go5G Next plans, as well as Magenta MAX, get unlimited text and up to 5GB of high-speed data, then unlimited data at up to 256Kbps in 215+ countries and destinations.

In Canada and Mexico, customers on these plans also get unlimited talk and text, and up to 15GB of high-speed data, then unlimited data at up to 256Kbps.

Other plans, such as Go5G, include unlimited text and up to 5GB of high-speed data in 11 countries (plus 10GB in Canada and Mexico). After that, it's unlimited data at up to 256Kbps in 215+ countries and destinations.

T-Mobile wins not just because of how affordable it is internationally — but in the air too. T-Mobile customers have access to free in-flight Wi-Fi.

Then there are the other nice travel perks that make being a T-Mobile customer a little better. For example, T-Mobile customers get discounts at Hilton Honors hotels. And if renting a car at Dollar Car Rental, T-Mobile customers don't need to refuel their tanks.

Drawbacks: You get what you pay for when it comes to data speeds. Don't expect to be able to do much on 256Kbps. If you want faster data speeds, you'll need to purchase an International Pass that includes a limited amount of data and unlimited calling over a set number of days.

2. Buy a local SIM card in your destination

Seasoned international travelers may remember when getting a local SIM card was the only way of staying connected while overseas. But even now, with all of the alternatives that we have, getting a local SIM card can still be a great option. Say you're staying in a country or region for an extended period. A local SIM card might be the best option to make local calls at affordable rates.

Depending on where you go, a local SIM card could be the most economical option. For example, when I visited Vietnam in January 2019, airport vendors offered local SIM cards with unlimited LTE data for just $8. This was cheaper than paying for even 1GB of data using Google Fi. So, I alternated between using this local SIM card for data and Google Fi for text messages.

3. Utilize an eSIM card

eSIM cards are a high-tech solution to getting a local number without having to hunt down a SIM card in your destination. Rather than getting a physical SIM card, you can purchase and download an eSIM on your phone to connect to cell networks and get data while overseas.

Tons of providers sell eSIMs online with options and prices depending on where you're going and how much you'll need to use your phone. So, make sure to dig around and check reviews before purchasing. But, let's take a look at one provider to show you generally how it works.

Airalo sells a variety of eSIMs that cover a combined 190+ countries and regions. You can search for eSIMs by country or region, or you can purchase a global eSIM that covers 87 countries.

Say you're heading to Europe and want to have data for navigating around the cities you're visiting. Airalo currently offers six European eSIM options:

• 1GB of data valid for 7 days for $5.

• 3GB of data valid for 30 days for $13.

• 5GB of data valid for 30 days for $20.

• 10GB of data valid for 30 days for $37.

• 50GB of data valid for 90 days for $100.

• 100GB of data valid for 180 days for $185.

As you can see, you can drop the price to just $4 per GB by buying 5GB of data or just $2 per GB by buying 50GB of data. That's very affordable compared to options like Google Fi — which can cost up to $10 per GB. However, you generally won't have access to SMS text messages through eSIMs. One option is to switch between using an eSIM for data and either Google Fi, Sprint or T-Mobile for text messages.

Airalo succinctly spells out the process that you'll need to go through when purchasing any type of eSIM. Generally you'll need to:

• Download the provider's app.

• Purchase the eSIM.

• Install the eSIM.

• Then activate the eSIM once you're ready to start using it.

One major restriction to this option: you'll need to have a phone that supports eSIMs. Also, you'll want to have some technical knowhow. As I've learned from experience, setting up an eSIM can be much harder than the Airalo screenshots make it seem.

4. Pay for an international plan add-on

If you want to use your phone number to call and text while overseas — and you don't have Google Fi, T-Mobile or Sprint — you're likely going to need to purchase an international add-on to your plan. The rates and options for these types of services are going to vary between cell phone providers. Let's look at Verizon's options as an example.

All unlimited Verizon plans include free talk, text and data in Mexico and Canada. Just beware that data speeds are reduced to 2G speeds after 0.5 GB per day. For travels outside the U.S., Mexico and Canada, you have two options:

For $10 per day, TravelPass will let you use your phone like you do at home with unlimited talk, text and data in over 185 countries. Get the International Monthly Plan for $100 per month to get a package of minutes, data and text messages for use overseas.

5. Embrace airplane mode

If you don't need to access data or SMS, you might embrace airplane mode. You're expected to turn it on before takeoff anyway. But upon landing, the cheapest way to avoid international phone fees is to never turn airplane mode back on until you touchdown in the U.S. again.

When airplane mode is enabled, your phone is technically disconnected from the cellular network, preventing it from searching for and connecting to foreign carriers. This not only conserves battery life but also eliminates the risk of incurring hefty roaming charges. However, you can still access Wi-Fi networks, allowing you to connect to the internet, check emails, or use apps like Google Maps.

To send messages via internet, scout out free Wi-Fi. Luckily, most international airports and hotels have it these days. Free Wi-Fi is also easy to come by at coffee shops, restaurants, malls and major tourist attractions.

If you're looking for the best way to use your cell phone abroad

The right solution is going to depend on what cell phone service you use in the U.S., where you're going and how much data you'll need. If you just want basic data to keep up on emails and search directions, using T-Mobile or Sprint can save you from having to pay when traveling overseas.

However, if you want high-speed data, you'll want to look into options like eSIMs or purchasing a local SIM card. And for those who want the simplicity of using their cell phone just like at home no matter where they go, Google Fi or an international add-on plan can be an excellent option.
