Why is there always a short message on the mobile phone? I was charged a lot of money. I want to ask a master to teach me how to solve it. I won't charge any more.

1. Send "0000" to 10086 or 100 10 to inquire about the service you ordered. If not, it's the phone.

2. If the mobile phone is made in China, please recall whether you have ordered those ancillary services, such as "weather forecast" and "constellation consultation", which will lead to fee deduction.

3. If the mobile phone is a smart phone supporting JAVA or a non-smart phone, please check the software you downloaded. Some software will charge in the background, and there will be charges for being silent and colorless. In this case, you can make a customer service complaint. After customer service follows up, your withholding fee will be refunded.

PS: I belong to the third category. I use S60 system. Before I downloaded the software, I got the withholding fee of 15 yuan. I called my mobile phone to complain, and my mobile phone was returned 15 yuan. Remind the landlord not to use the software indiscriminately, it will really pit money.
