How to solve the problem that SMS can be received but not sent?

1, the cell phone signal is not good. I suggest you try another area with good signal.

2, SMS center failure or maintenance, you can try another time.

3. The phone bill is in arrears or the SIM card is broken. Recharge the SIM card or try another one.

4. The number of SMS center has been modified, so it cannot be sent normally. Click SMS-Settings-SMS Center Number to check the SMS center number, and then search the local SMS center number online to see if the mobile phone is correct.

5. The mobile phone data is abnormal. You can restart it and try it, or if it doesn't work, try restoring the settings. Go to phone settings-More settings-Restore factory settings-Restore all settings (without deleting any data of the phone). Find the problem according to the above method and try to solve it.
