Straight Talk Coverage & Network

Unlike many cellular service operators, Straight Talk wireless is able to use the networks of all four of the main carriers in the U.S. and offers both GSM and CDMA connectivity. The quality of the coverage will, therefore, be similar to what you would experience if you were on the network of the host company.
Which network you are on–AT&T, T-Mobile, Sprint or Verizon–is dependent on your location when you activate your device and what phone model you purchase or bring to Straight Talk. Both Sprint and Verizon utilize the CDMA network and offer coverage through most of the U.S. and Hawaii. AT&T and T-Mobile use the GSM network and offer coverage in the U.S., Hawaii, Puerto Rico and some of Alaska. The GSM network is also used in many other countries.
The Straight Talk wireless network, much like the postpaid carriers, offers 4G speeds to its consumers, allowing for faster internet connection, better quality voice calls and faster text messages. To access this service you must have a phone that is capable of 4G LTE speeds and must be within the coverage area.
Comparing the coverage maps of the Straight Talk network with other wireless companies, Straight Talk wireless offers some of the better coverage in the continental U.S. Due to their partnering with the four largest carriers in the U.S., Straight Talk is able to offer fast connectivity to a wide range of people. If you can get AT&T, Sprint, T-Mobile or Verizon service, then you will likely also be able to use Straight Talk's network as well.
