Don't be superstitious about so-called antivirus software. In fact, there is no need to install antivirus, guards and housekeepers (not to say that they are useless, but that mobile phones are difficult to be poisoned, and their existence will only drag down mobile phones, except for things you don't understand).

Change your SIM card to another mobile phone and call 10086 to see if you can receive it.
