Signing up with AT&T means you get all of the benefits of a major carrier, including reliable customer service (with actual brick and mortar stores), a wide selection of phones, and excellent nationwide coverage. 

Ranking AT&T Plans By Popularity

Curious about which AT&T plans people are most apt to sign up for? Here’s a breakdown of all of AT&T plans by popularity.

Unlimited Premium PL: 26.2%
Unlimited Extra EL: 25.8%
Unlimited Starter SL: 17.5%
Value Plus VL: 16%
4 GB: 14.5%

Based on this, it seems to popularity of each of AT&T’s plans corresponds to how much data it includes. To wit, Unlimited Premium PL includes unlimited high-speed data, Unlimited Extra EL features 75GB, Unlimited Starter offers unlimited deprioritized data, and so on.

AT&T Coverage

AT&T delivers some of the best coverage in all of the country, blanketing nearly the entirety of it with 4G and 5G service. 

AT&T’s 4G LTE is the most wide-reaching in the country, outdoing the likes of Verizon and T-Mobile. The company’s 5G network, meanwhile, covers just a tiny bit less of the country than T-Mobile’s (the industry leader).

AT&T Customer Service 

As frustrating as some of the phone hold times can be, you can generally get in touch with AT&T representatives nearly any time of the day—which is something many prepaid carriers don’t offer. 

What’s more, AT&T stores are all over the place, so you probably aren’t far from one if you prefer in-person assistance. 

AT&T Phones

One of the biggest upsides of going with a major carrier is the wide selection of phones. AT&T stocks flagship and mid-range models from the likes of Samsung, Apple, Google, and Motorola—and frequently runs promotions that allow you to get them at discount prices.  

This makes AT&T a great option if you not only need plans but devices for your entire family. Some of AT&T’s recent promotions have included deals on the iPhone 17, the Samsung Galaxy S25, and the Google Pixel 10. 

The Bottom Line

If you’re shopping for the best 2-line cell phone plans in 2026, both T-Mobile and AT&T deliver standout options—just in different ways. T-Mobile continues to lead with perks, simplicity, and unmatched 5G reach, while AT&T shines with strong nationwide coverage, generous data allotments, and flexible plan tiers to match any budget. Whether you prioritize top-tier performance or everyday value, you’ll find that both carriers offer reliable choices that make staying connected with a partner, friend, or family member easier—and more affordable—than ever.
