The phone bill of my mobile phone (G7) in December was charged 40 yuan for Montnets SMS on-demand fee for no reason.

The charging trap built into the motherboard of this mobile phone is common to domestic phones or copycat phones. Some of them are in games or other software, and as long as you open it, the fee will be automatically deducted, which is hard to guard against, while some are automatically sent at a specific time, and even if you don’t touch the phone, it will deduct the fee from you. .

There is no way to fix this problem, because it is a problem on the motherboard of the mobile phone, so we can only prevent it!

The prevention method is actually very simple. There are different preventive measures according to different networks, such as China Mobile or China Unicom!

Mobile: Dial 10086, press 0, and ask the service staff to turn off the SP service (function) of the mobile phone, and that’s it!

China Unicom: Dial 10010 and choose a manual station, ask the service staff to turn off the SMS function, and that’s it! Because China Unicom does not have the term SP business, and the charging trap is caused by sending text messages, the text message function can only be turned off. However, in this case, the mobile phone will not be able to receive text messages!

General copycat phones are almost all dual-card dual-standby. If you have two cards, just turn off the function of card 1. Card 2 will not incur charges (provided that both cards are used) Card)

It’s so hard to sit on the bench in the cold weather, do you think...
