I have a Motorola 120t (yeah I know, it's old and busted ) and I've got a prepaid card, I typed in the ESN number then it gives me the following error: The serial number (ESN or IMEI) that you entered is already active. Please enter a different serial number (ESN or IMEI) or click on the add airtime button. Does that mean my cell is active now? I click the 'Add Airtime' link, then I type in Airtime Pin number, then it gives me the following message after I submit: The following error has occurred. The Airtime redemption card PIN you entered was not valid. Please call the TracFone Customer Care Center at 1-800-867-7183. That's such horsecrap!! I KNOW it's the correct pin number!!! I'll just have to call on Monday and hope I get through to anyone. The lines were busy all this weekend and I never could get any assistance. I know it was Christmas but still, even on a Sunday (today) I couldn't get through all day. I hope it's not using any of my minutes , but it shouldn't since I haven't made any calls or recieved any calls. And what does this mean?? I get this message when I turn my cell on: Airtime Card Due Date: 1/1/1 Also is it good to keep turning on and off your cell phone? I've been doing that I hope I don't wear something out. Thanks.
