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.
Why we love it: If you're looking for an extra line for a data-hungry teen, Sprint's Unlimited Plus plan makes a lot of sense. One line is $60, 2 lines are $100, 3 lines are $120, and lines 4 and 5 are free. This makes it easy to tack your son or daughter onto your plan without much financial outlay. And since each line is entitled to unlimited data, you don't have to worry about your Netflix and Spotify-streaming teen using up all of your plan's shared data. 

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.


Sprint: Unlimited Basic includes talk, text and high-speed data in Canada and Mexico. You can add Sprint’s Global Roaming service to any Sprint plan at no additional charge. With Global Roaming, you get free texting and 2G data. Calls made abroad start at 20-cents-per-minute. You can purchase high-speed data passes to get LTE data download speeds abroad
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.
Rent or purchase a cell phone or mobile hotspot for your trip and do everything you typically do with a cell phone such as make calls, check your emails, browse the web and use apps such as Google Maps, WhatsApp and others - but without the high international roaming rates most carriers charge. You can also use your own devices with our service by either using one of our SIM cards or renting an international MiFi hotspot.
But like the Unlimited Choice plan that preceded it, the Unlimited &More plan comes with a few big catches. Video streaming is limited to standard-definition quality, with the speed capped at 1.5 megabits per second. The plan doesn’t provide mobile hot spot capabilities, so no tethering your computer to your phone. (Verizon has similar restrictions.) And people who subscribe to the cheaper unlimited plan no longer get free HBO.
It’s important to know that unlimited never means truly unlimited. But it does mean that the amount of data you receive is so high, it’s unlikely you’ll run out. Most providers cap their “unlimited” data between 22 GB and 80 GB. The allotment is a far cry above standard 3 GB to 10 GB plans. We compared the price for these plans, too, which can run as low as $30 and as high as $75. Cell phone plans also become significantly cheaper per line as you add to the plan. So no shame the to new grad for staying on their parents' family plan — everyone is getting a better deal. Our favorite providers offered a reasonable price for generous data allotments.

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.
If you’ve got a GSM phone already, call your wireless company and ask to have it unlocked. Once your phone is unlocked you’ll be able to access other mobile carrier networks around the world. Not all phone companies will unlock all types of phones and often your account needs to be in good standing and open for more than 90 days, or your phone must be completely paid for and off-contract.
Galaxy Forever: Does not guarantee monthly payment amount, phone selection, or service plan rates. Upgrade after 12 payment as long as lease and early upgrades offered. Req. active line thru time of upgrade with min. 12 consecutive monthly service plan payments, new phone Lease Agreement, acct. in good standing, & give back of current eligible device in good & functional condition. After upgrade, remaining unbilled lease payments are waived. Upgrade does not include same generation model Galaxy, must be next generation Galaxy.
Even as carriers offer multiple tiers of unlimited data plans, the T-Mobile One plan remains the best choice for families. It gives a family of four unlimited data for $160 a month. We wish T-Mobile still let you stream HD video as part of its T-Mobile One plan, but for most users, 480p video on a smartphone-sized screen will be good enough. (Families can pay an extra $10 per month per line if they really want HD streaming.) T-Mobile's network delivers comparable performance to Verizon, which charges more for its best unlimited family plan, though Verizon also lets you mix and match different unlimited options for each line of your family plan.
Due to constantly shifting promotions and terms, family-plan pricing is difficult to sort through. Our Verizon single-line pick isn’t competitive here because all of the lines on a Verizon subscription share the same data bucket. Verizon’s largest capped-data option is 8 GB, so if that won’t cover your family’s usage, you have to upgrade to more expensive unlimited data plans: $130 for two lines of not-so-versatile Go Unlimited and its limits on mobile-hotspot and streaming-video use ($160 for Beyond Unlimited), or $160 for four lines of Go Unlimited ($200 for four lines of Beyond Unlimited).
However, switching to prepaid, where you pay for service before you use it, can be an easy way to save $10 to $20 a month or more. Many prepaid services are provided by smaller companies that simply resell service from one of the big carriers, so they offer similar coverage as those carriers at a lower price. But for these resellers to undersell the major carriers while using those carrier networks, the resellers make some trade-offs; similarly, the major carriers’ own prepaid plans tend to involve restrictions their postpaid plans lack. We don’t recommend switching to prepaid unless you meet most of these criteria:
Just make sure to turn off your cellular and data roaming so you don’t accidentally get stuck with charges. To do that on an iPhone, go to “Settings > Cellular” and click the switch next to “Cellular Data.” Also go to Cellular Data options and make sure “Roaming” is turned off. On most Android phones, go to “Settings > Mobile Networks > Data roaming access” and then click on “Deny data roaming access.”
Finally, you’ll need to buy and install a local SIM (subscriber identification module) memory chip that will work in the country you’re visiting. This little circuit stores information like your identity, local cell phone number, address book information, and other bits of data. When you put a local SIM chip in your phone, it’s like getting a brand new phone that will work on the local mobile carrier’s network. The chip does need to be activated so you can either go to a mobile store in the country you’re visiting and have everything taken care of on the spot, or try to order one in advance and activate it online.
If you make frequent trips overseas, T-Mobile’s plan is a no-brainer, especially now that more countries are covered. The carrier includes unlimited data and texting as part of its standard T-Mobile One unlimited plan (albeit at slower speeds than you’re used to in the states). If your calls include a lot of overseas numbers, it may even be worth upgrading to T-Mobile One Plus International for an extra $25 a month, since it lets you make calls to landlines and mobile numbers in many countries at no additional charge. Sprint offers something similar with its new unlimited plans and their access to the Global Roaming feature. But T-Mobile will cover you in more countries after July 22.
Why we love it: T-Mobile's ONE plan has proven popular, so much so that it compelled the entire wireless industry in the direction of unlimited. ONE is still arguably the best of the bunch, though, packing in more features than the competition. If you're over 55-years-old and use your phone's data heavily, getting this plan at $50 is a steal and a half.

Sprint: Sprint currently has some big discounts on Android and Apple devices, letting you get $450 back when you buy an iPhone X, iPhone 8, or iPhone 8 Plus if you add two new lines or one new line with a one-line upgrade — no trade-ins required. Sprint is also offering the best iPhone XS deal of all the carriers right now, letting you score an iPhone XS totally free or an XS Max for just $75 ($4.17 per month) with the trade-in of an eligible last-gen flagship. Android deals let you score the Samsung Galaxy S9 for $270, the Galaxy S9 Plus for $324, or the Galaxy Note 9 for $360 when you purchase one on an 18-month rent-to-own Sprint Flex lease.
With Verizon’s TravelPass you can use your plan in Mexico and Canada for $5 per day. The charge jumps to $10 per day for use in other countries. Usage in Canada and Mexico are included in Verizon’s Go Unlimited, Beyond Unlimited and Above Unlimited plans at no additional charge. Verizon’s Above Unlimited plan includes five TravelPasses each month, good in more than 130 countries. The carrier also offers monthly and pay-as-you-go international roaming prices.
Verizon’s CDMA-based network (used when you don’t have LTE service) isn’t capable of simultaneous voice and data use. This means, for instance, that if you’re using your phone to navigate while you’re driving, and you get a voice call in an area without 4G service, you may lose the call. But the company’s far-flung LTE deployment has addressed this limitation in many areas.
If you need quality voice and text coverage but use little or no data, and you’re willing to stick to a small, if growing, subset of Android phones, Republic Wireless is the best bet. At just $15 a month, it’s the cheapest way to get unlimited voice and texts, and adding 1 GB of data (with hotspot support) on the Sprint and T-Mobile networks tacks on another $5.

Speed and capacity – When you really get down to it, the specs on the OnePLus 3T are mightily impressive. It comes with a Snapdragon 821 processor and 6GB of RAM as standard meaning functionality, and speed is fantastic. The basic (cheapest) model also comes with 64GB of storage, allowing you to take as many travel pics as you want without receiving storage notifications every 2 minutes.
