Excluding plans that don’t let you bring your own device, Metro by T-Mobile, formerly MetroPCS, has the best rates for two-line scenarios—$70 for 5 GB each on two phones. That pricing easily beats T-Mobile’s own prepaid plans, and Metro by T-Mobile’s data caps exempt streaming video (at the cost of limiting its resolution to DVD-quality 480p resolution, although you can opt out of this Data Maximizer feature if you want).
If you travel internationally, Verizon’s TravelPass can seem tempting. That option costs a reasonable $5 a day in Canada and Mexico to use voice, text, and data drawn from your domestic allowance, $10 a day in much of the rest of the world (with a few exceptions, such as Saudi Arabia and Qatar). But Verizon phones are all sold unlocked, so you can (and should) save money by using a local prepaid SIM when traveling internationally.
We focus on the Big Four because they dominate the market. But consumers looking for a good deal or great customer service should also check out smaller companies. Our ratings of 20 providers are based on the experiences of about 100,000 Consumer Reports members. The Big Four are all near the bottom of the chart, though T-Mobile rates somewhat higher than its competitors. (Ratings are available to members.)
T-Mobile offers one of the simplest solutions for traveling overseas. If you subscribe to the company’s T-Mobile One unlimited plan or are clinging to one of its Simple Choice plans with tiered data, you automatically get unlimited data and texting in more than 140 countries around the world. As of July 22, that number will grow to 210 places, T-Mobile says. If you want to place or receive calls, you’ll be subject to the local rate depending on where you want to go. You don’t need to notify T-Mobile of your travel.

Given that a traveler is always on the go, battery life matters the most. Apart from that, a good camera and global compatibility with different cellular networks is a big factor. Looking at these criteria, the Samsung Galaxy S7 Edge fits the bill. It’s priced well, supports various global networks including VoLTE, and has a 12MP camera and good battery life with 3600mAh capacity.


When you're purchasing a cell phone, make sure the device you select has sufficient memory, speed, camera precision and general functionality to meet your needs. You can choose between locked phones, which require you to pick a carrier, such as T-Mobile, AT&T, Boost or Verizon, or you can go with an unlocked model that works on a variety of networks. Best Buy, Amazon and B&H Photo Video are just a few stores that sell unlocked phones, including Apple iPhones and Android devices. Consider a prepaid phone with limited functions if you're purchasing an inexpensive device to take with you to festivals, nightclubs and other places people frequently lose expensive cell phones.
