Sprint's revised unlimited plans include benefits when you travel to Mexico and Canada. The Unlimited Basic plan offers 5GB of LTE data on top of unlimited talk and text in those two countries, while the Unlimited Plus plan doubles data to 10GB. Both the $60 Basic and $70 Plus plans give subscribers access to Sprint Global Roaming in 185 places around the world.
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.

Verizon offers the best coverage in the most places in the US, so you’re more likely than with other carriers to have a signal wherever you are—the most important thing for a smartphone to do. And though Verizon isn’t the least expensive carrier for unlimited-data plans, the company’s under-promoted single-line 5 GB plan (just $55 after an auto-pay discount) includes more data than most people need while saving you money compared with an unlimited plan. But if you truly need unlimited data, or frequently travel internationally, you should consider T-Mobile’s One Plus.
Each call is priced at a per minute rate for international toll, plus airtime and applicable charges and taxes.  Rates vary, based on country called.  Per minute rates only available from a customer's local U.S. Cellular home calling area.

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.
With the understanding that there are many cell phone plans that could potentially suit a senior, we've chosen to focus in on the ones specifically geared towards this market, and selected the best of the bunch. Whether you're a senior shopping for yourself or a loved one looking for a gift for a relative, it's worth taking a look at the following plans. 
If your usage only slightly exceeds the cap on a service’s limited-data plans—say, you use 3.25 GB in a month and your carrier offers a 3 GB plan—you should see if that plan lets you roll over unused data from months when you don’t hit your maximum. Also, see if that service offers unmetered slow 2G service once you exhaust your high-speed data, so your phone will still always get basic (read: slower) Internet access. These features may let you choose a less expensive plan.
If it’s time for you to get a new cell phone, then you probably already know that you'll have a whole host of decisions to make before you choose your new cell phone plan. There are more options than ever when it comes to choosing a smartphone and wireless plan. These days, there's more carriers than ever, and their offerings are much more diverse than ever before. More carriers means more competition, and ultimately, that's good for you, the consumer. The Wirefly comparison engine is the best way to compare cell phone plans on the web.
RootMetrics strives to be as comprehensive as possible in its methodology, which includes testing reliability and speed during file uploads and downloads, while downloading email, and while downloading files similar to typical web pages. Testers also measure how reliably each network places and maintains calls and how reliably and quickly subscribers can send and receive text messages.

Opting for Google’s Project Fi seems like a really great idea for a variety of reasons. First, the nuts and bolts: You can get calls and texts for $20 per month, and data for $10 per GB of use (and you can add extra people for $15 each). But what exactly makes the plan unlimited? You're only charged $10 for the GBs you use up until 6 GBs, then beyond that, it’s unlimited.
If you have eyes only for your budget, we’d suggest avoiding the Big Four entirely and instead choosing a cheaper MVNO provider like Cricket or Republic Wireless. MVNOs do not operate their own networks and instead offer access to one or several of the major carriers’ networks at a reduced cost. Choosing the right MVNO requires knowing which network it uses and whether that network works well where you live.
Use a tablet with cell capabilities — If you already own a 3G/4G tablet, there’s a chance it was unlocked when you bought it. If so, you can use this when you travel instead of a phone — just buy a data-only SIM locally, and use Skype and WhatsApp for your phone and SMS requirements. You can also use the tablet as a hotspot, to share the connection among your other devices.
You can also look at phones that are ranked as best in class. This includes rankings for phones with the best battery life, thinnest form factor, highest quality display, and other high-end features. However, battery life is frequently dependent on your habits and how you use your phone. For example, if you check your email or text a lot, or you have lots of long conversations, you will burn battery life more quickly than someone else.
Prepay accounts in the United States offer anonymity to criminals wishing to obtain telecommunications services. The phones cannot be easily traced to a specific individual. Without call patterns that can be correlated to placed or received calls, there are very few effective ways for law enforcement to monitor or intercept communications between unregistered phones. This becomes even more difficult if encrypted services are also utilized.
Verizon is the nation’s largest carrier for good reason: It offers the best coverage in the most places in the US according to third-party tests and surveys (including those of PCMag and RootMetrics), so you’re more likely to have a signal no matter where you are, and its pricing is competitive with that of AT&T, Sprint, and T-Mobile for the amount of data that most people actually use. It isn’t the best choice for people who frequently travel outside of the US or who want unlimited data, but it is the first carrier everyone else should look at.
