Simple mobile is one of the top prepaid GSM brands available. Simple Mobile runs on the T-Mobile network, and offers 4G LTE data plans.
*30 day Unlimited Plans include a fixed amount of high-speed data per 30 day cycle. If you reach the high-speed data threshold, your data speed will be reduced to as low as 64 kbps for the remainder of the 30 day cycle. If your data speed is reduced, the reduced speed may impact the functionality of some data applications, such as streaming audio or video or web browsing.
