I just received a phone from my friend. It is a palm 755p and apparently she took the sim card out and the phone does not function at all. All that happens is a vascillation between "access power" and "palm" Can you help. There is now no sim card in the device. should i get another sim card?
If the Treo 755p had a SIM card, it will only work on ATT or T-Mobile. You can get a new SIM card from ATT or T-Mobile and activate the phone that way.
