M8 can't send text messages, but can receive text messages and make phone calls. What's the problem (firmware has been brushed n times)?

1. Please confirm whether your SMS center number is set correctly.

2. Please confirm that your SMS function is normal (not turned off by the operator).

I suggest you change your mobile phone and try again to make sure that the SIM card itself is a network problem.
