When i upgraded to the Note 9 , i was using the upgrade on another phone on my account. I was trying to avoid having the line that i took the upgrade from deactivated because we don't stay in the same house and all he has is a cell phone for me to contact him. I was told by AT&T that once i got the new phone all i had to do was not use the new sims card that came with the note and that i could just take the sims card from my s8 and put it in the note.I did this and the phone is working fine under my number, but i'm not getting any security or software updates and the sims card numbers don't match on my att account. Since i didn't activate the phone the traditional AT&t way could that be the reason i'm not getting the security updates?
