I'll teach you. The first part, you put on the mobile card first, and then go in. There is a network mode in the mobile network settings. GSM is mobile. If you have a CDMA option in your phone, change the phone and change the card. If there is no one in the network selection, then your system must have been swiped. All right. ! I don't know if yours is an official system or a DIY homemade system with parallel machine brush. If it is a self-made system, you can just go to major forums and find a telecom brush package to brush it. It's simple. Ask me if you don't understand.
