A ‘Geeker has given BigDiesel07 confirmation that Sprint is launching a new service tomorrow. This service, avaiable for anybody who has the Unlimited Data Plan, will get unlimited calls to ANY mobile number, not just Sprint phone numbers.
 It is called ‘Any Mobile, Any Time’. It will only be available on the new everything data plan (both individual and shared) and ONLY the new SERO plans (Sorry any current SERO plan holders).
