You were right it indeed worked. Now I’m worried though that I’m missing out on features. What is VoLTE or other things I could be missing out on? Would ATT charge me for a new sim?Yes, absolutely.
Hmm, might want to have the AT&T SIM replaced though just in case it's old and doesn't support features such VoLTE, etc.
I start counting left to right with the first 2 numbers on the left correct?Check your SIM per below. Go to settings/about and check the IMEI number
SIM card compatibility
AT&T HD Voice requires a SIM card that is UICC-G or higher SIM card installed in your smartphone to enjoy the rich calling experience of AT&T HD Voice. Want to make sure to find out if your SIM card is HD Voice compatible? In the SIM card number, look for the digits 27 or higher in the 9th and 10th positions.

Sorry Bob, I was mistaken on the number It is the ICCID, not the IMEII start counting left to right with the first 2 numbers on the left correct?
My sim reads: 35 3XX210 156XX7 1
I put x’s for safety but that’s how it reads. Looks like I need to get it replaced?
No worries. I checked and the 9th and 10th digits are 27. So does that mean I’m good no other reason to swap out the sim?Sorry Bob, I was mistaken on the number It is the ICCID, not the IMEI
Check that number and I apologize for the confusion
It means you are good. I see no need to swap out the SIM. Mine are 27 as well and I have VoLTE and HD Voice.No worries. I checked and the 9th and 10th digits are 27. So does that mean I’m good no other reason to swap out the sim?
