The mobile phone can answer the phone and receive short messages, but it can't make phone calls and send short messages for help. Is there a signal on the mobile phone?

It doesn't count whether you can call the operator normally.

Set SMS center number

Clear cache and data

Remove the battery and restart it.

Test the SIM card on another mobile phone?

Check whether address book/contact guidance is disabled.

Use third-party communication software

Restore factory settings

The following steps are recommended:

1. Turn off the phone again.

2. Try to insert the SIM card into this machine (check whether the mobile phone card is in arrears).

3. Check whether the mobile phone is equipped with software such as security guards or incoming calls, uninstall it and try again.

4. Whether the attempt to update the version of the mobile phone system has improved.

5. Back up mobile phone data (phone book, SMS, multimedia files, etc.). ) and restore the factory settings.

If the problem still exists, it is recommended to send the mobile phone to the nearest Samsung service center for testing and maintenance.

If the phone can't make a call, we suggest that you:

1. Check whether the phone is in airplane mode.

2. Check whether the cell phone signal is stable. If the network signal is not good or there is no signal, please turn it off and restart, and search the network again. If it doesn't work, it is recommended to take out the SIM card and try to insert it again.

3. Check whether the mobile phone has enough balance.

4. If you can dial some fixed numbers, check whether the fixed dialing function is started. It is recommended to disable this feature.

Note: When fixed dialing is disabled, the PIN2 code will be prompted. The network operator needs to query the password.

5. Check whether the call barring function is set. If so, please cancel and try to make a call.

6. Replace other SIM cards.

7. Back up data (contacts, text messages, pictures, etc.). ) and restore the factory settings.

If the problem still exists, I suggest you take the purchase invoice, maintenance card and mobile phone to the local Samsung after-sales service center, and professional engineers will help you test it.

Mobile phones can answer and make calls, but they can't receive (send) short messages. The reasons why you can't send text messages should be analyzed as follows:

1, is the SMS center number set correctly on the mobile phone? If it is not correct, it will directly lead to receiving text messages instead of sending them. You have to change it. If it is correct, you can call 10086 for free, and press 0 to serve you manually ~

2. If the number of SMS center is correct or you can't send SMS, it's a cell phone problem.
