We're fans of cross-carrier calling plans like T-Mobile's myFaves calling feature, but we get even more excited when unlimited text messaging comes along for a bargain price. That's just what T-Mobile is now supplying, as subscribers of myFaves calling plans now have access to unlimited SMS and MMS for $9.99 per month. This is a $5 per month discount off T-Mo's $14.99 price for non-myFaves customers, so this discount is a very nice 33 percent decline. Word is that the promo will be available now until September 12th.
