Buy a disposable phone — If you’re in a country for a while and all you need are calls, texts, and maybe some light web browsing, just buy the cheapest prepaid phone you can find at the local mobile store. Sure, it’ll probably be complete rubbish, but you can often pick these phones up with a bit of credit for next to nothing and they’ll do the job for a while. The upside? You really won’t care if you drop it in the hostel toilet. If it does survive the length of your trip, just pass it onto to somebody else when you leave.
AT&T's size, reputation, and brand recognizability also means they don't have to beat other carriers on price to stay competitive. AT&T's plans are among the most expensive on the market, though a recent overhaul of their unlimited offerings have made them a bit more reasonable. The main things you're paying for with AT&T are coverage, features (like hotspot allotments) and international options.

The other option is an unlimited-data plan, but these aren’t truly unlimited: All four carriers have carved out restrictions on things like hotspot use and streaming video, while adding premium tiers or for-fee add-ons that lift some of those limits. As a result, shopping for wireless service can look a lot like buying a plane ticket: You can’t jump on the cheapest price you see, lest you wind up in Basic Economy.
Finally, we didn’t factor in taxes and regulatory fees, because they vary by jurisdiction (on my own T-Mobile plan, for example, these fees added up to just under 10 percent of my July 2018 bill). But wherever you live, taxes and fees should hit you equally across all of your options—except for T-Mobile’s T-Mobile One offering, which sweeps them into the advertised cost.
Flexing that unlimited vacation policy and staying abroad for more than a week or two? Consider replacing your SIM card and using a local service provider. First, make sure your phone is unlocked. You can do this by swapping your SIM card for another one and confirming that your phone still works, or simply calling your service provider. The FCC requires that providers unlock all devices so you can use them on any network, so simply ask your provider for an unlock code. One caveat, though: That rule doesn't apply if you're locked into a contract or you haven't paid for your phone in full.
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.
