T-Mobile Unlimited Any Mobile plan Apr 4This may come as a shock, but some smartphone owners use their device as an actual phone. You know, to like, call people. If you’re part of that camp, and happen to do business with T-Mobile, the carrier looks to be introducing a feature just for you. Starting April 4, “T-Mobile will offer Unlimited Any Mobile, a $10 per month subscriber-level feature that includes unlimited calling to any domestic mobile number, including Puerto Rico, regardless of the carrier,” a leaked document acquired by TmoNews says.

If you’re a current T-Mobile customer and love to talk, you can add this to your plan without extending your contract. In addition, it doesn’t affect your current plan in any way, meaning you can add or remove the new Unlimited Any Mobile whenever you want. While T-Mobile does offer unlimited plans already, this is a great feature for folks who don’t need the minutes year round.
