Other then using airplane mode or keeping the battery out . How do I make sure that my touch diamond (donor phone) never connects to sprint. I would ideally still like to use it as an mp3 player or to stream music since it has wifi. I am just afraid that I will accidentally turn airplane mode off.
I tried loading a cricket prl and also a verizon prl, but when I made a test call with the prl loaded, the call went threw!
Any ideas.
