I'm not too much of a buff in the CDMA field, but I was wondering, does someone who has a push-to-talk capable phone, HAVE to be on a push-to-talk plan? Say if I bought a Motorola V60p and brought it into a store to activate it with VZW, would I have to be on a push-to-talk plan? Or could I just activate it under a regular plana nd not use the PTT?
