T-Mobile to launch unlimited data plan

Posted: Updated:

T-Mobile is bringing back its unlimited data plan on September 5, after a year's hiatus.  This time it's with 4G coverage.   However, before you get too excited about it, there is one big rule you need to know about.  Customers are not allowed to tether their smartphone to their computer, or use it as a mobile hotspot.  

T-Mobile's new plan will cost between $69.99 and $89.99 a month.  With the latest package, T-Mobile joins Sprint as the only large national carriers to offer unlimited data plans.
