Which carrier has the strongest signal?

In the U.S., three providers offer 3G service: AT&T, Verizon Wireless and Sprint . The fourth nationwide carrier, T-Mobile, says it will roll out its 3G network starting later this year.

All of the major US 3G networks are scheduled to shut down in 2022 . Whether you’re with AT&T, T-Mobile, or Verizon, this may affect your phone, your home alarm system, or even your car.

Verizon offers by far the most coverage in the country. If you constantly find yourself without a signal, Verizon will be your best friend.

Typically You get around 5 miles from the tower, though theoretically a gsm tower can broadcast up to 20 miles . There are also cell repeaters that can extend useful range to around 15 miles or so. I have heard reports of longer range, but 15 seems like a reasonable expectation.
