Can you edit the text first and then send a text message according to the other party's phone number?

It depends on whether you have a mobile phone number. It also depends on whether it is the first time to use it. If it is the first time to use it, you should set the SMS center number (+86 13800XYZ500, where XYZ is the area code, for example, Guangzhou is +86 13800200500 and Shenzhen is+86138007500, and the zero before the area code is removed. Unicom can send it directly.

I hope you are satisfied with this answer, thank you!
