AT&T data enabled SIM card not working
13 Oct 2015
AT&T Wireless offers many different data plans. Only certain data plans work with our rugged handheld computer products. A consumer "smartphone" or "tablet" data plan will most likely not work. The rugged handheld computer would more likely work with a "laptop modem" or "USB adapter" data plan instead. If your AT&T SIM card will not enable 3G data on the rugged handheld computer, please contact AT&T to switch to a compatible data plan or to obtain an alternative SIM card that has a compatible data plan enabled already.
