How much does T-mobile charge for Mobile to Mobile minutes?

You can use whenever min whenever. m2m are only available with the family plan and are unlimited or with a business plan.

 

Mobile to mobile costs the same as a regular call (if you have gone over your regular allotment) unless you have a special plan (like the family plan) that gives you free mobile to mobile.

Mobile to mobile is deducted from your included minutes.

Free mobile to mobile only applies to calling other T-Mobile customers in the United States. That is to say, you cannot call a Verizon Wireless customer and get it free under mobile to mobile or call a T-Mobile UK customer in London and expect it to be free of charge.
