The problem of sending text messages on mobile phones is urgent! ! (high score)

Hello, if I guess correctly, the mobile phone you bought must be a fake brand-name phone. If it is a fake brand machine, this problem is normal. At present, most fake brand machines have built-in malicious fee deduction programs, which will automatically send customized short messages of Monternet services without your knowledge. These malicious deduction programs are solidified in the mobile phone system, and it is difficult to delete and brush fake brands. So I suggest you change your mobile phone and don't use a cottage. Now you can buy a good brand machine for a few hundred dollars, so there is no need to spend money on those fake machines with messy functions. Sell this mobile phone to a second-hand mobile phone store, and then buy a brand machine (Nokia, Samsung, Motorola, Lenovo, Tianyu, OPPO, etc. ).
