AT&T Unlock code
Bear with me, this might be confusing. All phones discussed below are Iphones.......
My mom was with AT&T but is moving onto my plan (Verizon). She initially thought she had to have a "Verizon" phone. My sister had one that she wasn't using, and my mom moved her number and service to my sister's phone. While during that process, the verizon rep let us know that her current phone was eligible to be used, we just had to have AT&T unlock it.
As of right now, all her contents (pics, voice mails, notes, etc) are still on her AT&T phone. We received an approved unlock email from AT&T.... but here are the instructions that came with the approval email:
Using a Non-AT&T SIM Card
1. Remove your SIM card and insert the new SIM card.
2. Complete the setup process.
Using an AT&T SIM Card
1. Back up your iPhone.
2. When you have a backup, erase your iPhone.
3. Restore your iPhone from the backup you just made.
Right now the SIM card in the phone is still the AT&T SIM Card. She doesn't want to erase her phone though. She just wants the verizon service to be on her AT&T phone. Does she have to do the back up and erase the Iphone and restore? Or can she just now insert her Verizon SIM card and move the service to that phone?
