A wireless carrier is the company you use for wireless
services for mobile devices. These services can include calling, text & SMS messaging,
and / or Internet data.
The carrier for your device can be found on the device itself or
shown on the first screen when you turn your device on. Some tablets are Wi-Fi only, which means that
they only operate on a Wi-Fi enabled network from a local wi-fi router. Typically,
when you purchase a tablet from a wireless provider then it will have 3G / 4G capabilities.
