To use Telestial SIM cards, your device will need to be GSM-compatible (Global System for Mobile Communications). In the United States, some carriers like Verizon and Sprint use CDMA 2G/3G networks, which is a different technology to GSM networks (which is used by just about every other country in the world). CDMA networks too are moving towards GSM technology, especially utilising the high-speed LTE networks.

Assuming you make fewer calls than average, and you don’t need Verizon’s better network, Ting offers flexible billing and a choice of Sprint and T-Mobile coverage. Ting consistently ranks high in Consumer Reports reader surveys and placed well in past PCMag surveys (although it faded in that site’s latest round of reader assessments). And with Ting’s recent addition of third-party device financing, you can even have some of the same low up-front phone costs as with the big four.

Sprint Unlimited Basic Plan: Includes unlimited domestic calling, texting, 500MB LTE MHS, VPN & P2P & data. MHS reduced to 3G speeds after 500MB/mo. Third-party content/downloads are add’l. charge. Plan not avail. for tablets or MBB devices. Select Int’l svcs are included for phone lines. See sprint.com/globalroaming. Subsidized devices incur an add'l. $25/mo. charge.

We used the iKits charger (white with gray) for a two week long trip in the UK. This charged even our sensitive devices (one phone and three Kindles) well and became our sole electronics charger for tablets and phones after the first day. The adapters snap in snugly and create a single unit that is secure, easy to use, and compact for travel. It is well made and fit securely everywhere we stayed. We never had surge or power issues.


Voice-call quality has improved as three of the four carriers (Verizon, T-Mobile, and AT&T) have built out Voice over LTE (VoLTE) service and made it interoperable. (Sprint doesn’t plan to begin its VoLTE rollout until this fall.) And across the board, data caps have risen to reflect customers’ increased demand for data: All four major US carriers now offer unlimited data plans and have refrained from curtailing them since T-Mobile and Verizon’s late-2017 pruning of their unmetered deals.
Look for more tie-in deals from the carriers that throw in one video service or another, along the lines of T-Mobile’s free Netflix subscription with two-line plans, Sprint’s Hulu deal, AT&T’s WatchTV bundle, and Verizon’s $20 discount on a bundle of unlimited wireless and a triple-play of Fios Internet, phone, and TV service. (These media tie-ins are essentially another way carriers try to keep you around without the handcuffs of two-year contracts. Watch for new-lease or early-upgrade deals, but treat them with a fair amount of skepticism; buying your phone independent of service gives you far more leverage.)

The phone you’ll receive will be a local phone, good for making calls in the country in which you are traveling. However, if you are spending more than a week or two in one destination overseas, you may save money by purchasing a local phone and subscribing to a local phone plan, as rates for renting a phone can quickly surpass the cost of a cheap cell phone in a few weeks. Also, domestic calling rates for rental phones may be higher than rates offered by local cell phone service providers.


Why we love it: If you rely frequently on your phone to provide a WiFi signal to your other devices, Boost Mobile's Unlimited HD plan is worth a close look. In addition to allowing you to skip a credit check and worries about extra taxes and fees (they're baked into Boost's prices), the plan gives you a whopping 20GB of full-strength hotspot data a month. This is a dream if you do frequent tethering.  
Most major U.S. phone companies give you the option of choosing a plan that allows you to make calls, send texts and access data while traveling abroad. These plans may be offered on a daily basis or as a temporary service that you can set up for a single month when you know you’ll be leaving the country. Each company offers different plans for various prices that work for a number of phone models and in designated countries. Per-minute calling rates vary for different countries.
Right out of the gate there are some restrictions including limited streaming for gaming at 8Mbps and music streaming is limited to 1.5Mbps, but if you can handle those limitations, the Sprint plan is hard to beat on a nationwide network. The good news is that while you might have some data restrictions, you’ll also find unlimited calling, text, and data in Mexico and Canada as well as the United States.

TracFone, Net10, and Straight Talk, all properties of the Mexican carrier América Móvil, consistently rank among the most widely used prepaid services. They offer the advantage of reselling service from all four carriers, at the cost of having to trust the company’s judgment about which network works bests for you, as Prepaid Phone News editor Dennis Bournique explains in a helpful post.
If you'd prefer to use a different Android phone or an iPhone, T-Mobile remains a strong alternative, letting T-Mobile One subscribers use data in more than 210 countries, though at 2G speeds. You can talk and text for free in Canada and Mexico, though T-Mobile limits you to 5GB of LTE data in those countries. (Be aware that the carrier's new T-Mobile Essentials unlimited plan doesn't include these international perks.)
Verizon’s 5 GB pricing barely beats that of T-Mobile and Sprint’s unlimited plans, but those two carriers’ options (and even Verizon’s own $75 Go Unlimited plan) limit what you can do with that data in ways that Verizon’s plan does not—most notably, by limiting streaming video to DVD resolution and limiting either the speed or the volume of hotspot use. This 5 GB plan includes full-speed mobile hotspot use and allows HD streaming video, albeit capped at 720p resolution on phones and 1080p on tablets. (That streaming video limit remains undocumented as of August 2018 outside of a brief mention in the second-to-last paragraph of a press release.) So as long as you—like a large chunk of the wireless population—don’t use more than 5 GB in a month, Verizon’s continued network advantage still makes this plan a good deal.
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.
As of this writing, Sprint still offers a particularly attractive incentive to leave your current carrier behind: It will give you free unlimited data for the next year, though you're still on the hook for taxes and fees. After November 30, 2019, your bill reverts to Sprint's standard rate for unlimited data, which is listed as $60 for a single line. The big caveat: You need to bring over an eligible phone to qualify for free data. (Since the deal is geared toward AT&T and Verizon customers, there's a better chance your phone is eligible if it came from those carriers.) The offer is listed as a limited-time deal, but Sprint has kept it around since the summer of 2017.
New smartphone releases are generally on the pricey side. If you aren't dying to have the latest device as soon as it comes out, waiting a few months for the price to drop can really pay off. Apple products typically take around a year to decrease in price. Most new Sony, LG and Samsung products become substantially more affordable within three to six months after release. Amazon and eBay usually have good selections of these products, and both frequently offer cell phone promo codes and coupons. If you're a dedicated early adopter, look for presales, which might offer an opportunity to save some cash.
