Why can a mobile phone send text messages online, but it can't make and answer calls?

The common reasons why mobile phones can't answer calls and their solutions are as follows:

1, check whether the mobile phone is in arrears, and suggest paying for recharging;

2. Check whether the mobile phone is set with call forwarding, flight mode on and call barring. Suggest canceling and try again;

3. Check whether the function or signal of the mobile phone is normal. It is recommended to change your mobile phone or location and try again.

4. Try to restart or change the phone to see if you can answer the phone;

5. Bring the mobile phone card to the local business hall for testing or replacement.

After the above reasons are eliminated, it still cannot be used normally. It is recommended to go to the business hall for repair.

Troubleshooting of common faults in answering and making phone calls by mobile phone;

1. The mobile phone cannot receive the verification code.

This may be caused by the following circumstances:

1. Interception software is installed in the mobile phone, and the verification code cannot be received. It is suggested to remove the SMS interception of application software or try to change the mobile phone.

2. The mobile phone is turned off, there is no signal for the time being, and the payment is overdue or the verification code and SMS are not received when it is stopped. It is suggested that downtime due to arrears will generally be resumed within 24 hours after payment, basically within 24 hours. It is recommended to change the mobile phone number or get it again the next day.

3. If the mobile phone is used abroad or can't receive the SMS verification code, I suggest you try to get it again in the future when the signal network is delayed.

4. SMS storage is full, and SMS verification code cannot be received. It is recommended to turn it on and off as much as possible.

Second, the phone will be black.

1. The distance sensor of the mobile phone is blocked.

The black screen of the mobile phone may be blocked by the distance sensor. Check whether there are foreign objects in the earphone accessories above the front of the mobile phone. If you clean it up, the general problems can be solved.

2. Fault of distance sensor

When the distance sensor fails, it is impossible to correctly judge whether there is an object approaching, which may lead to misjudgment that there is no object approaching when making a call and then turn off the screen of the mobile phone. Therefore, it is recommended to send the mobile phone to the official designated maintenance center for maintenance.

3. The mobile phone distance sensor software is set incorrectly.

Incorrect setting of the distance sensor may also lead to a black screen during the call. It is recommended to check the settings of the mobile phone again.

The sensor is out of order due to the lack of leather pad.

This situation is generally a mobile phone after disassembly or screen change. In fact, the touch screen is replaced or the mat at the bottom of the sensor is lost.

The solution is: there are two small holes on the original touch screen, and there is a small cushion under the holes, which is about 3 mm thick. The size and distance of the two holes are just the same as those on the touch screen. Just paste one and cut it out as the wrapping material of the battery.
