Fuqing Unicom suddenly failed to receive the signal.

If your mobile phone has no signal, there are generally the following reasons:

1. The mobile phone is turned off due to arrears, and you can't use it after the operator blocks the signal. In this case, it is necessary to recharge and pay the arrears before the mobile phone can be used normally.

2. Because of the signal failure of the local operator, the mobile phone can't receive the signal. I suggest you call the local hotline 100 10 to find out whether this situation exists.

3. If the mobile phone card or mobile phone is broken, I suggest you try changing the card or mobile phone to test it. If one of them is damaged, it is suggested to check the card in the local business hall. If the card is damaged, you can replace it. If the mobile phone is broken, you can repair it.

4. Temporary busy network may cause short-time signal problem of mobile phone, and try again later; If the cell phone signal is poor for a long time, you can try to replace the cell phone or turn it off again to eliminate the cell phone problem.
