New phone, same SIM card ? Shouldn't this work ?
I have a replacement unlocked phone for my existing unlocked phone on an AT&T prepaid plan.
I transferred the SIM card from the old phone to the new one.
On the "Update Device" page, I am trying to enter the new IMEI number, but get the following error message:
"Please try again, ONLY enter a NEW SIM and/or IMEI. Your entry included an existing SIM or IMEI number."
The phone is brand new, directly from Motorola, so the IMEI is clean.
Do I need an actual different SIM for this phone ?
