A Special Device - Copy Phone Number of the Contact

Tweet

There is something wrong with my phone card, my mobile can’t read the contact’s number. That is disaster. Hundreds of phone numbers is in this SIM card. I go to business hall to change to a new phone card with the same number. That is the only thing I can do. To my surprise, the professional person in business hall has a cool device to transfer all contact’s number from one SIM card to the others. Thank goodness, I don’t need to type phone number one by one. What a cool day. Do you have the similar experience?
