FAQs
My SLe-GSM-3/4G was shipped with an AT&T SIM card. Can I switch to another 3/4G carrier if I do not have AT&T coverage in my area?
No other carriers are available for use with the SLe-GSM-3/4G radios. However, these models use AT&T PLUS sim cards that have a large service footprint. You can check the 3G/4G coverage on the AT&T website (www.att.com and search for "check wireless coverage maps"). If the radio must be installed in an area that has low coverage or no AT&T coverage, you have the option of installing the 2G T-mobile SIM card in the SLe-GSM-3/4G radio.
