Our sim cards are with the AT&T mobile network - America's largest nationwide mobile network, servicing the USA, Hawaii, the US Virgin Islands and Puerto Rico and giving voice, SMS and 3G/4G data. AT&T is America's most reliable network and covers more than 99% of America's population

Should you have any issues when you're in the USA, you'll be able to contact us 24x7 on our USA Support Line, or you'll be able to contact AT&T directly for help.

(The coverage map shows the scope of your coverage area. Map depicts an approximation of outdoor coverage. Actual coverage area may differ substantially from area shown on map, as coverage may be affected by terrain, weather, foliage, buildings and other construction, signal strength, customer equipment and other factors which do not allow AT&T to guarantee coverage or network availability.)
We provide genuine AT&T sim cards - not through a mobile network that resells the AT&T network - meaning you'll be connected directly to the AT&T network. And they're not cut to size sim cards either.
You can find out more information about AT&T on their Wikipedia page by clicking here or by going to their corporate website by clicking here.
The AT&T network operates on the following frequencies:
2G/EDGE: 850MHz and 1900MHz
3G/UMTS/HSPA+: 850MHz and 1900MHz
LTE/4G: 700MHz, 1700MHz and 2100MHz.
