What if Sharp 7228u can't send a message? I can't find the information center code.

Although I don't use your mobile phone, I have encountered this situation. I wrote down some methods collected online.

Method 1

Find a friend's mobile phone with the same brand and package, refer to the SMS center number above and re-fill it on the mobile phone.

Method 2

Go to menu → Information → Settings → SMS → Information Center → (A set of numbers will be displayed here).

Mobile phone to 10086.

Unicom telephone 100 10.

Ask for the number of the SMS center, write it down after asking, change the original SMS center number in your mobile phone to the number you asked, or rebuild 1 information center.

Method 3

Hello! Please operate in the following ways to confirm whether you can solve the problem of not sending text messages:

1. Please reset the SMS center number: +86 13800XYZ500, where XYZ is the area code, for example, Hangzhou is 571;

2. Please check the message sending format in the SMS settings. The correct format should be "text" or "text";

3. After the setting is completed, please turn on and off the machine and send yourself a text message to test;

4. If it doesn't work, please change the card to another mobile phone for testing.

If the above operation does not solve your problem, please call 10086 again. Thank you for your cooperation!

Try it, it should solve the problem. How much do you know about Baidu Hi?
