My mobile phone card sends messages to mobile customers in other provinces, and the other party can receive them. What's the problem with sending it back to the other party and not receiving it?

Is your mobile phone allowed to receive short messages?

Look at your SMS settings and the number of the information center. What is the information center number used? Is it allowed to reply with the same information center number?

Also, when you switch the SMS storage location to the memory card or switch from the memory card to the mobile phone, pay attention to the setting of your information center number! Set it up and try again! I had this problem when a classmate asked me to repair her mobile phone! I set it up for her!

If these settings are correct, I suggest you go to the mobile business hall or Unicom business hall to have a look! Maybe you closed this basic mobile phone business to Wu!

I hope your mobile phone will be ready as soon as possible!
