I switched from Verizon to AT&T last week by getting an iPhone now a friend of mine still on Verizon tells me not to text them anymore because they get charged to send/receive texts from other networks. Is this true? Someone confirmed for me already that we as AT&T customers (iPhone) users do not get charged to text Verizon customers, but is the same true in reverse? They have an unlimited text plan on Verizon I think.
