Why does the mobile phone automatically hang up the text message?

If your mobile phone is disconnected, I suggest you try again after changing the network environment (such as outdoor) to verify whether it is a signal coverage problem. If the signal is normal and there is no object blocking the antenna, it is recommended that you turn on the "flight mode" and hold it for at least 15 seconds before turning it off. If it still can't return to normal, I suggest you call the customer service hotline 100 10 to check this problem.

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 to pay 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. If roaming to other places can't be used, it is recommended to check whether the local network signal is normal and whether the number has been roaming;

5. Try restarting or changing your mobile phone to see if you can answer the phone;

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