StraightTalk users: have a question ... A friend had a CDMA phone (no SIM) that broke. Ordered a new fancy GSM phone ... Arrived with no SIM card as the assumption was original phone had one. So, now ST says they have to send out a SIM card. But I thought, hey, could you buy the cheapest GSM phone (complete with SIM) from Walmart and them transfer it to that SIM and use in new fancy GSM phone? Help.
