T-Mobile Introduces First Nationwide Unlimited 4G Data Plan

T-Mobile customers with a penchant towards high-speed data will be able to add an unlimited 4G data plan to their service starting September 5. The nations first unlimited 4G data plan will be available for as low as $20 dependent on the customers current plan.

T-Mobile has promised not to cap or throttle the new unlimited data plan.

The $20 price plan is available to customers on T-Mobile’s Value voice plan. Customers on Classic voice and text plans can pick up the service for $30. Under the new offering, the Value plan with unlimited talk, basic text messaging, and unlimited nationwide 4G data will cost $70 per month

In comparison, the single line Classic plan — which offers unlimited talk, unlimited text, and unlimited nationwide 4G data — costs $90 per month.

T-Mobile is currently operating on the 1,900MHz band of HSPA+, a slower 4G option compared to LTE technologies being utilized by AT&T, Verizon, and Sprint Wireless. While the mobile data network may be slower, the service should work with just about every GSM/HSPA+/4G phone at HSPA+ speeds.

T-Mobile’s biggest win from the space could be its ability to attract users who are already using the iPhone 3GS, iPhone 4, and iPhone 4S models, all which offer HSPA+ connectivity but fall shore of 4G LTE services offered by their available carriers.

Apple and T-Mobile have been in negotiations regarding spectrum use with T-Mobile, hoping the new partnership will finally deliver the iPhone line of devices by the end of 2012.
