The Xiaomi Mi 2A phone has a card that shows that it can only use emergency calls

Hello. Xiaomi mobile phone shows no service, it is recommended that you check it according to 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.

If the above methods still do not help you solve the problem, please go to your nearest repair point for repair inspection.

It is estimated that your China Mobile** card is faulty, you can call ** to the mobile customer service first. Or you can plug that ** card into another mobile phone and try it.

There are 2 possibilities, 1. There is no signal on the mobile phone. 2. The mobile phone card is down. 3. The mobile phone card is not inserted properly.

1. There is no signal on the mobile phone: you only need to move to an open place with a good signal.

2. Mobile phone card downtime: If the mobile phone card is down, you can only call emergency**, and you need to recharge.

3. The mobile phone card is not inserted properly: you need to take out the mobile phone card and insert it again.

In this case, the SIM card is not correctly recognized, or the SIM card is not inserted into the phone, so it can only be displayed for emergency calls. Here's how to fix it:

1. First, use the card pin to pull out the SIM card slot.

2. Check whether the SIM card is installed correctly, if it is not installed, install it and insert it, if it is not installed, then insert a SIM card.

3. After inserting the SIM card, then wait for the mobile phone to read the SIM card network, and when it is read out, then the emergency call will not be displayed.

Reasons: 1. ** card arrears;

2. There is no signal at the location;

3. The card slot is in poor contact with the ** card.

What should I do if there is an emergency-only call on my phone?

1. Mobile phones are limited to emergency calls, which means that they can only dial 110, 120 and 119.

5. Turn on the automatic selection switch.

2. If there is an occasional no signal, it is usually caused by network failure, you can consult the operator to know when to recover.

3. Go to [Settings] - [Mobile Network] - [Select Operator] and turn on [Auto Selection].

4. Go to [Settings] - [About Phone], and click [Kernel Version Number] continuously to enter the "CIT" (hardware detection) interface.

Find [SIM Card Detection] and click on it to perform SIM card detection. If it is detected as a hardware problem, you can go to the after-sales service for maintenance.

The mobile phone prompts "emergency call", and there are generally the following reasons for this situation:

1. There may be a mismatch between the mobile phone card and the mobile phone;

2. The mobile phone card has been damaged, it is recommended that you can bring your valid certificate to the business hall to handle the card replacement business;

3. The mobile phone is in poor contact or your location is caused by a signal blind spot or a sudden lack of signal.
