In what could be viewed as yet another bid by AT&T to keep customers from defecting to the Verizon iPhone, the carrier today announced that it will launch tomorrow a new "Mobile to Any Mobile" feature allowing unlimited calling from AT&T phones to other mobile phones in the U.S., regardless of carrier.
The feature, which rolls out tomorrow, requires customers to be on a qualifying voice plan and to have an unlimited messaging plan, which costs $20 per month.
Beginning Thursday, Mobile to Any Mobile will be available to new and existing AT&T customers with a qualifying voice plan who subscribe to unlimited messaging plans. Existing customers with an unlimited messaging plan can activate Mobile to Any Mobile by visiting www.att.com/anymobile. The URL will be available beginning Thursday.AT&T has been taking a series of steps to combat the threat posed by the Verizon iPhone, tweaking its tethering plans to offer more data capacity and touting its network's ability to handle simultaneous voice and data.
