PHS SMS sending failed.

In this case, 1, first of all, you need to determine whether the short message you sent to other mobile phone numbers is normal and whether the other mobile phone can successfully receive the short message, so as to determine which side the problem is.

2. If you can, please check whether SMS is enabled on your mobile phone to send reports. If the tip fails, call the other party directly to ask if it is acceptable. If there is, just turn off the SMS report directly.

3. Is the other party's SMS box full? Please delete some and try sending again later.
