My mobile phone is Nokia 523. I don't know why I can't get the verification code on my mobile phone, and I can't even get the verification code of Taobao Shanda, the inquiry message of 186.

there is a malicious plug-in in your mobile phone.

1: make sure whether the mobile phone is equipped with software that can automatically block short messages, such as Xinyi' an. If there is, it will be easy. Just add 186 to the white list.

2: Call 186 to ask if the mobile phone blocked your number (it is very unlikely, but it doesn't mean it doesn't happen).

3: Take out the memory card and try it. If you can receive it, it means there is something wrong with the memory card. Back up pictures, music and other materials and format the memory card.

4: restore the factory settings or format the phone.

5: use system software such as appman or x manager to check whether there is a thread of servertimer or mssver.exe. If there is, close it and try again.

6: close Servtimer.Data in the process, and then find the Servtimer.Data file in drive C, and just delete it. Also, check whether there is a srvfd.exe process in the process, and close it! Then find out and delete in disk C and disk E, then re-create a srvfd.exe folder and restart. Solve it!

7: SIM takes it to another machine to try. If it can be received normally, it means that it is a problem with the mobile phone itself. If there is an error in this machine, run process management first, end all processes without gears, and then delete this file in the C:/SYSTEM/DATE directory, restart it and get it done.

8: In fact, the simplest, fastest and most effective solution is to format the mobile phone! (Be careful to back up important information such as business cards and information before formatting) Enter "*#737#" in standby mode, and then enter the default password of 12345. When the mobile phone is restarted, you can receive the information normally. If not, just hard-grid it!
