The landlord must have bought it somewhere or asked questions about medical care.

I left my personal information or phone number,

This belongs to some harassing calls,

I suggest you use Tencent mobile phone housekeeper to intercept it.

Just turn on the harassment interception function and add this healthy phone to the blacklist.

At the same time, it can also help your mobile phone physical examination, virus killing, private space management and so on.

You can also use the whitelist function.

Add your own address book to the white list,

Select to receive only incoming calls and text messages from the white list.

I hope I can help you.
