Editors' Note: We've published the results of our 2018 network testing. Current rankings reflect last year's results, but we plan to update scores along with new customer service rankings for wireless carriers before the end of the year.
It would be tempting, and not entirely wrong, to think of Boost Mobile as the Mini-Me to its parent company, Sprint.
Boost uses Sprint's network and essentially offers the same performance. And like Sprint, Boost is pushing unlimited plans, though with a few more restrictions than what Sprint now offers.
Carrier Performance (33/40 points)
As noted above, Boost relies on Sprint's network, so Sprint's recent improvement in our network test results means that Boost's overall performance has improved, too. On the downside, Sprint still trails other major carriers when it comes to LTE speeds, so that means Boost still falls behind rivals like Metro by T-Mobile. Even worse, Boost had the worst result on our app download test, so when we update our grades to reflect our most recent round of LTE testing, Boost's numbers may take a hit. As of this writing, though, Boost's score still reflects its 2017 performance.
The newfound popularity of unlimited plans has prompted Boost to offer more unlimited plans of its own.
Plans (16/25 points)
The newfound popularity of unlimited plans has prompted Boost to offer more unlimited plans of its own. There's still a tiered data plan that gives you 3GB of LTE data for $35 a month, but you now have two different unlimited options at Boost plus a third, limited-time program.
Boost's $50 unlimited plan gives you 8GB of LTE hotspot data, while placing limits on your video, music and game streaming. (MetroPCS's comparably priced unlimited plan also limits video streaming to 480p resolution, but has no such restrictions on streaming music or games.) A new $60 Unlimited Plus plan at Boost allows HD video streaming, while raising streaming speed caps on music and gaming; you also get 20GB of hotspot data. As for Boost's limited-time $80 unlimited plan, it doubles hotspot data to 40GB, adds international calling options and throws in a Tidal Premium subscription.
Additional lines on Boost cost $30 each for the $35 and $50 plans; you can add extra lines to the $60 Unlimited Plus plan for $40 per month.
When calling Boost for tech support, be prepared for a lot of automated menus.
Customer Service (14/20 points)
To get answers to questions during our undercover customer-support testing with Boost, we had the best luck using Twitter and Facebook. Responses on social media are prompt, though you should expect a little back and forth, especially on Twitter. Boost offers some fairly thorough online resources, too, but the carrier lacks an online chat feature for getting more detailed responses.
Our biggest frustration came from Boost's phone support, which is seemingly set up to discourage you from talking to an actual person. Be prepared for a lot of automated menus, which will try to answer questions about your account.
Phone Selection (6/10 points)
Expect a solid mix of phones from Boost. Among dedicated prepaid carriers, it has the second largest selection, after Straight Talk, with most phones available for less than $300. The biggest knock here is that Boost's bring-your-own-device offer is restricted to devices that work on the carrier's CDMA network.
Featured Boost Phones: iPhone XS, iPhone XR, iPhone XS Max, Galaxy S9, ZTE Max XL, Moto G6 Play, Moto E5 Play
Special Features (2/5 points)
Boost subscribers now get the same Tidal benefit available to Sprint customers — six free months of Tidal HiFi, which normally costs $19.99 a month. If you opt for Boost's tiered-data plan, you can stream music from six different services, including Spotify and Pandora, without it hitting your monthly allotment. Boost also offers a free video-streaming app called Boost TV, but to take advantage of content from ABC, A+E Networks and Fox, you'll need to upgrade to the premium package, for $10 a month.
For international use, Boost sells a $5-a-month add-on that lets you make unlimited calls to Canada and Mexico and text internationally. You also get up to 8GB of data roaming while traveling in Mexico. The $10 package includes all of that plus calls to landlines in more than 70 countries and 200 minutes of mobile calling to more than 50 countries.
If you want to knock some money off of your bill each month, you can sign up for Boost Dealz. You'll be exposed to ads and offers whenever you unlock your phone and, in exchange, will get a $5 account credit every 30 days.
