Perhaps in response to Verizon's new Apple toy, AT&T has launched unlimited mobile to mobile calling and texting, on any cell network.
So you can call your Verizon or Sprint or T-Mobile or Cricket friends and have it not count against your plan minutes.
Sprint has offered a similar plan for some time now.
The feature, on AT&T, is included for customers with unlimited messaging plans ($20 for individuals; $30 for families) who subscribe to $39.99 and higher Nation individual plans or $69.99 and higher Family Talk plans.
Current customers can change their accounts online or by calling a rep. New customers have to request the option when signing up.
