Hey guys so if you ordered your iPhone 6 or 6+ from AT&T and just moved your SIM card over from your old phone (then probably got a message telling you that you need a new SIM card and to visit an AT&T store but ignored it, like I initially did)...the old SIM card works but apparently does not support HD Voice per AT&T tech support.
You have to call in to activate the new SIM card if you bought the phone outright or did NEXT because if you try to do it online, it forces you into a 24 month contract.
This is only if you ordered from AT&T online, not if you ordered from Apple, or bought in an AT&T or Apple store.
