i've got a sim card in my phone. I have a 8W in my car. It's to hard to change the card.
open the phone, put the mini card in a adaptator, and then put the card in the 8w.
If i could have 2 card with the same number, when i enter in my car, i just turn on the 8w and off the pocket phone.
If someone can clone my card, it would be very good.
