Frustrated with your service? Get the same coverage for half the price

If your experience with Verizon, AT&T, or T-Mobile is giving you gray hairs, consider swapping your plan for one from an MVNO carrier. These smaller carriers operate on the exact same towers as the Big Three, but offer MUCH cheaper plans, and often a much simpler customer service experience if you ever need to get in touch.

An alternative to Verizon is Visible, which offers unlimited everything with Verizon's 4G and 5G coverage for just $25/month. We especially love that you can opt for unlimited premium data and global calling benefits, for just a few bucks more.
To get T-Mobile's excellent 5G without the premium price tag, check out Mint Mobile instead—you'll get 5G speeds, up to 40GB of premium high speeds, plus unlimited talk, text, and data for as low as $30/month. (Mint is one of our favorite carriers on the market.)
Want to stay on AT&T's network? Consider Boost Infinite. You can get unlimited everything with Big Blue's coverage for just $25/month. We especially love that you can lock in your cheap plan price forever.

Verizon Customer Service Phone Number

1 (800) 922-0204

J.D. Power classifies Verizon's customer service as "among the best," awarding the carrier five out of five power circles in 2018. That's a pretty amazing score for a mobile company of this size (the nation's largest). Here's a guide to our favorite unlimited Verizon plans.

AT&T Customer Service Phone Number

1 (800) 331-0500

AT&T customer service ranks third in J.D. Power's major carrier customer service rankings, behind T-Mobile and Verizon. This equates to three power circles, or "about average." AT&T has a difficult reputation in this regard, but recent moves indicate that the carrier is open to feedback and willing to improve. Here are our current favorite AT&T plans.

T-Mobile Customer Service Phone Number

1 (877) 453-1304

T-Mobile touts their customer service as "the industry's best," and if J.D. Power's annual awards are any indication, the carrier truly does leave its subscribers with a good feeling. Dial this number to judge for yourself! And while you're chatting, why not multi-task and check out our picks for the best T-Mobile cell phone plans.
