Hi! If you confirm that you are buying the Telecom version of the Xiaomi mobile phone instead of the telecom contract phone, it is recommended that you check it by following the following methods:

Whether the SIM card is inserted correctly.

Whether the wrong SIM card is inserted, such as the standard version inserts the telecom SIM card, etc.

Go to Hardware Detection to see if the SIM card is working properly (enter * * on the dial screen). If the SIM status is normal, go to step 5, or if the status is unknown, go to step 4.

Try to replace a different SIM card, if the status is still unknown during hardware testing, it is recommended to go to the repair point for testing; If the detection status is normal, it is recommended to go to the carrier to replace a SIM card (the SIM card may be aging).

Whether the network type is correct and whether the carrier selects Automatic. (China Unicom selects 3G priority, mobile selects only 2G, and China Telecom selects automatic).

If the network type of the non-telecom mobile phone is CDMA automatic, you need to change the network type to "WCDMA Preferred" in the mobile phone information (**) to solve the problem.

Whether there is no signal in the area. You need to check whether other mobile phones on the same network have signals.

Back up your data, flash to the latest system version and try again.

Exactly the same problem as the landlord. If you buy the wrong version, you won't exchange it and you won't refund it in full.

It must be that there is some software on the new mobile phone that you didn't open back to buy the mobile phone and she will help you.

You may be stuck in jamin, or you may have airplane mode. You can also go to the phone store to see if the card slot is broken.

If the Xiaomi phone has a poor mobile phone signal, you have to make sure that you put the phone in a place with a very good signal, such as by a window, or go out for a walk with the phone.
