You come home from vacation. You’re relaxed. You’re refreshed.

Then you check your cell phone bill and find that you owe $800.

International roaming rates are nothing to mess around with, so it’s important to know what you’re on the hook for before you travel abroad. We’ve surveyed the mobile landscape and picked out the carriers and plans that are most friendly to frequent out-of-country travelers.

Keep in mind that bringing your own phone with a U.S.-based plan might not be the most cost-effective option.

For most countries, T-Mobile is where it’s at. The carrier includes unlimited texting and 2G data in more than 140 countries with every T-Mobile One plan. Talk costs 20 cents per minute, a relative bargain compared with other international voice rates.

If you can’t go without high-speed data for the trip, you can upgrade to T-Mobile One Plus for an extra $5 per month. This upgrades your international roaming data speeds to 3G.

In Mexico and Canada, you get access to your monthly 4G LTE data allotment, plus unlimited talk and text, all included with your plan. Few other carriers comes close to beating that.

Sprint’s Global Roaming international add-on — which you can sign up for at no charge — is also worth a look. Sprint gives you free texting, free 2G data and 20-cents-per-minute calling in most countries around the world.

  • Sprint: You can purchase high-speed data passes to get LTE data download speeds abroad

How They Compare to other carriers

  • Verizon: $10 for every day you use your phone outside of the country. In Mexico and Canada, it’s $5 per day per line. You keep your Verizon talk, text and data allowances. The carrier also offers monthly and pay-as-you-go international roaming prices.
  • AT&T: The basic international plan costs an extra $40 per month for unlimited texting, $1-per-minute talk rates, and 200MB of 2G data (25 cents per MB afterward)

Best prepaid international roaming plans

Only two prepaid carriers allow international roaming beyond North America: Google’s Project Fi and MetroPCS.

While abroad with Project Fi, you get up to 3G data speeds (and sometimes even 4G, depending on the country) at a rate of $10 per GB, plus unlimited texts. You’ll be charged only for the data you use, with no overage fees. Voice rates in most frequently visited countries are 20 cents per minute and can be even cheaper over Wi-Fi.

MetroPCS’ World Calling add-on has a good bit of South America covered, plus Mexico, Canada, Spain, Switzerland, Japan and Thailand. World Calling costs $10 extra per month and gets you 200 minutes of talk, 200 text messages to send (unlimited received) and 200MB of data while you’re in those countries.

Things to Know

        • Project Fi: You’ll have only four phone options: the Nexus 6P, Nexus 5X, Nexus 6 and Google Pixel. Stateside, Project Fi uses a combination of networks: Sprint’s, T-Mobile’s and U.S. Cellular’s, plus public Wi-Fi when available.
        • MetroPCS: It also offers Canada Unlimited service and Mexico Unlimited service, each at $5 per month. You get unlimited texts and calls within Mexico or Canada, plus access to as much data as your MetroPCS plan allows, although you’re not guaranteed 4G LTE speeds while outside of the U.S.

Alternative options

There are some good options from U.S.-based carriers now, but it’s always worth researching carriers in your destination country, especially if you want high-speed data access.

Buying a cheap prepaid phone when you get off the plane can often be much more cost-effective than using your usual plan abroad. Or, you can call your carrier and ask whether your phone is compatible with international SIM cards. If so, you can buy a prepaid SIM in your destination country and simply pop it into your phone for access to the local network.

Methodology

We evaluated all the major international roaming cell phone plans on the market, including those offered by AT&T, Google’s Project Fi, MetroPCS, Sprint, T-Mobile and Verizon Wireless.

To determine the best plans, we looked at the price of the international roaming option before taxes and fees, the price per gigabyte of data, and the price of international calls and texts.
