Let someone else's mobile phone cut off the signal and use someone else's mobile phone number to send text messages for fraud. How did you do that?

You watch too many TV plays. With such high technology, you have already sold money. This 1200. Why are you texting?

It is possible that your uncle's card is copied, not reissued. At this time, both cards can be used!

Let me explain to you, if both cards are opened, then the last card opened is the network listening state. In other words, the previous card has a signal, you can make a phone call, but you can't. The latter card can be used as both calling and called, so you are calling the second card. The first card has a signal, but it can't answer the phone. At this time, the second card bad guy may make you unable to access through technical means, but he can send text messages, so the situation you mentioned above appears. If, at this time, your uncle suddenly calls with the first card, then the second card can't be called, so the network only recognizes the last card to operate on the network, which is also the reason why the bad guys can succeed.

If you want to copy the card, you must get the original card, so your card may be copied before use. So you can go directly to the mobile business hall to get a card, and don't go anywhere else, otherwise he will copy it and sell it to you. That's not a big loss!
