Which you can not access.
What you want to do when you change out the motherboard but keep the 3G card, also keep the SIM card.
(The modem/radio on the card is "paired" with the SIM card.)
I don't understand. I used the original modem and SIM card and it didn't work. What do you mean "modem radio on the card"? Which card? The SIM card?
There has to be something that ids the motherboard, though, because I've tried using the original SIM and modem.
