WHY DO I NEED TO KNOW MY SIM PIN?
I have an iPad Air 4th Generation with an ATT prepaid cellular data plan (currently 7GB for 30 days). THE DEVICE IS NOT PREPAID, THE CELLULAR DATA PLAN IS PREPAID.
I had to buy a new SIM ATT 5G SIM card in order to activate cellular service because my old iPad device has a SIM card that is not compatible with the new iPad Air.
The new SIM card has been installed in my iPad Air and the cellular account has been activated.
However, I still do not know what my SIM PIN is. The Authentication Kit from the AT&T 5G SIM that I bought yesterday has a SKU number, a UPC number, and an ICCID number. It does not have a PIN or a PUK number on it.
1) I don't use the SIM CARD LOCK function on my device. Do I still need to know my SIM PIN?
2) Is there a default PIN? For example, I read yesterday that sometimes the PIN is the last 4 of the cellular data phone number. How would I test this?
