T-Mobile introduced a whirlwind of changes last year as it rebranded itself as the "Un-carrier," with perhaps its most substantial shift being the decision to forgo annual contracts, breaking away from a long-standing practice among carriers in the US.

AT&T Free Msg: We’ve noticed you’re continuing to enjoy the tethering feature with your smartphone service. Remember, you need a tethering plan ($45/mo, incl. 4GB) to use this feature, so we’re planning to update your line with the required plan soon.
Yes, the carrier everyone loves to hate is cracking down on unauthorized tethering - and they are automatically switching violators onto AT&T's 4GB data plan with tethering access, at a steep $45 a month.
