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.
You’ll want to start your shopping by checking for the strongest networks in your area. RootMetrics lets you check network coverage in your neighborhood and you can search the site’s map by area code, city, or neighborhood, and zoom in as much as you want — the site analyzes coverage almost to the backyard level. You can apply filters from the drop-down menu to look at specific providers or at specific types of coverage, like voice versus data. We’d recommend comparing two providers with the strongest coverage in areas you frequent, like home, work, or school.
All you need to do is figure out how much data your family needs and what you’re using it for the most. It’s important to note that some carriers are now making you pay extra if you want high-definition-quality video streaming or high-speed mobile hot spot service. Some also make you buy a more expensive plan if you want overseas service included. Check our buying guide for cell phones and service for tips for choosing a plan.
Verizon is the nation's largest carrier, boasting a staggering 149 million subscribers as of 2017. Pretty impressive for a company that's technically only been around since 2000 (after a merger between GTE Wireless and Bell Atlantic). Verizon was the first to launch a wireless high-speed broadband network, and the first to build a large-scale 4G LTE network.
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.
Metro and Boost charge the same $30 to add extra lines to one of their data plans. That means a family of four would pay the same $140 a month for unlimited data on every line. We give the nod to Metro, because the network of its parent company T-Mobile performs better on our test than that of Boost parent Sprint. We also like its included Google One storage, though Boost offers more hotspot data with its plan.
The memory on your mobile phone determines how much data you can store on it. Some phones have a predetermined memory capability that is built into the phone. You cannot change the memory amount on these phones, so be careful when you pick a phone that it has the memory amount you want. Internal memory starts at 1GB. A phone with expandable memory, on the other hand, uses a chip for memory. This means that you can replace the memory chip on your phone with a chip that his more memory later.
