Now T-Mobile USA Announces Flat-Rate Too; SMS/MMS Included For $99.99

So now I may not have to change to AT&T (NYSE: T) after all: T-Mobile USA, which is the carrier I have been using for a long time (and Staci and Tricia here do too), has also announced a flat-rate unlimited package, costing the same as the ones announced by Verizon Wireless (NYSE: VZ) and AT&T earlier today. The plan from T-Mob is $99.99 and begins Feb. 21, and cover all types of mobile messages, including pictures, in addition to voice calls.

Meanwhile, Sprint (NYSE: S) said today that it was testing plans in four markets with unlimited voice, text and Web access for $119.99 and $149.99.
