We’ve just been tipped that T-Mobile is set to roll out another plan option to their Mobile Broadband price lineup with the addition of a 2GB data plan for $39.99. The price will drop to around $32 when in combination with an existing voice plan. Along with that, the current $29.99 plan drops the overage penalty in favor of throttling for anything over the 200 MB allotted amount. Both changes take effect this Thursday, April 28th.
