Does this PDF show where the IMEI number is stored in the SIM card?
Where I live, T-Mobile voice coverage stinks (compared to AT&T).
However, I had to switch from AT&T to TMobile because AT&T forces you to have a data plan for all your kids' smartphones even if you don't want your kids to have a data plan (and even if you do not buy the phone from AT&T).
The sole determination of whether or not AT&T penalizes you for using "what they consider" a smartphone is based purely on the IMEI number.
If your child's SIM card IMEI indicates any other phone than a smartphone, then, you won't get charged for a data plan (unless, of course, you use data, but I always have data blocked - which they will do for you).
I want to consider whether it's possible to spoof the IMEI in the SIM card.
QUESTION: Does this PDF I just found searching (which is admittedly dry) show us WHERE the IMEI is stored in the SIM card?
