My mobile phone is Huawei Glory 3x. I can't send the mail, it shows resend. Why?

The reasons for the failure of SMS sending are as follows:

Mobile phone shutdown;

Solution: Check whether the mobile phone is in arrears and stop, and recharge it in time.

The network signal where the mobile phone is located is not good;

Solution: Try to resend it in an open outdoor place or service area.

Mobile phone failure (extremely unlikely);

Solution: Try to restart or upgrade. If it can't be solved, try to refresh the system.
