Updated: clarified that unlimited applies to both to and from / added info for existing Sprint customers
Sprint today announced "Any Mobile, Anytime", a new service plan feature that allows unlimited calling to and from any mobile phone, regardless of carrier. Only calls to/from landlines, calls while roaming, and international calls are deducted from plan minutes. The feature is now included with all of the company's existing "Everything Data" plans, which start at $69.99, and also include unlimited data and messaging. Sprint customers already on these plans will receive the new feature at the start of the next billing cycle. Sprint customers on other plans can switch to a qualifying plan without renewing or extending their contract.
