I changed my sim card and now my contact names are gone in iMessage?
So i just unlocked my iPhone and switched the sim card from ATT to another carrier (optus) and wanted to change numbers just because this is a temporary switch.
Now when i go to messages my contacts all appear as phone numbers instead of their names. I still have them in my phone if i go look at the contact/address book but they don't appear in messages.
I want to switch it to names not numbers.
(I still have the original sim and have it backed up to my computer if that helps)
iPhone 5, iOS 8.1.3
