T-Mobile subscribers can rejoice in the fact that the mobile service provider is dropping overage charges on the 5GB data plan, making it actual unlimited data coverage. Don't jump for joy too quickly though, as there's a down side to this.
Prior to this development, T-Mobile subscribers who had an unlimited webConnect data plan were actually limited to 5GB each month, with a surcharge of $0.20 per megabyte for everything over that. Now, with dropping this fee, the plan essentially becomes unlimited. Unfortunately for those with a 200MB monthly data plan, charges won't be eliminated entirely, but reduced from $0.20 to $0.10 per megabyte.
According to Fierce Wireless, the catch is that T-Mobile will now "throttle" bandwidth speeds for any customer that exceeds that 5GB benchmark. However, T-Mobile hasn't revealed how much this will slow data service down. Perhaps that won't be seen until it happens.
But for now, read up on full coverage and additional updates regarding T-Mobile's data plan developments over on ZDNet's Mobile Gadgeteer.
