Independent network calling is taking free mobile-to-mobile calling within your network to a new level! This service is currently being offered by two national providers, Alltel and T-Mobile and regional provider SunCom. They have made it possible for you, the customer, to assign the telephone numbers you talk to the most to your calling plan for unlimited calling. All calls made to and from your designated numbers to your cellular phone will not go against your calling plan minutes.
Alltel's my circle and T-Mobile's myFaves services are offering free calling to any number in the U.S., whether its a number on your provider's network, another wireless network, or a landline. Alltel and SunCom let you choose 10 numbers while T-Mobile allows five. Each month you can update your list of numbers via the web or by calling customer service.
