What happened when the mobile phone detected that it was a telecom card but there was no signal?

Check the cause and solve it:

1. Check whether the mobile phone card slot or sim card is damaged: you can try to insert another mobile phone card. If the card slot is damaged, it is recommended to replace the card slot.

2. Mobile phone shutdown due to network delay: you can turn on the mobile phone flight mode, turn it off after five seconds, or restart the mobile phone.

3, where the signal is not good, you can search elsewhere if you can't find the signal.

4. The card sticker is not installed or damaged: some locked mobile phones need to cooperate with the card sticker to search for signals. Please install the card sticker and use it. If the card sticker is damaged or the phone has been upgraded, replace the card sticker.

If there are other related matters, you can also consult the local business hall.
