What if I can't send a text message after changing my calling card?

According to the description, you can refer to the following methods to deal with the problem that mobile phones can't send short messages:

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

2. In the information interface, press the phone menu key-Settings, and click Restore Default Settings to try.

3. If the SMS center is out of order or repaired, you can try it another time.

4. The phone bill is in arrears or the SIM card is broken. Recharge the SIM card or try to replace it.

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

6. The mobile phone data is abnormal. You can try to restart it, or if it doesn't work, try to restore the settings. Go to phone settings-More settings-Restore factory settings-Restore all settings (without deleting any data of the phone).
