How can I control my family s unlimited data usage time?

Since it's your family, just explain your meaning directly.

Generally, when it reaches 20G, the speed will be limited, and the Internet speed will be slowed down.

The ** tariff is different for each place.

And there are many types of ** that can be handled.

It is recommended to call 10086 or go to the business hall to confirm before processing.

If the mobile phone card Internet function is turned off, you can call 10000 and ask the staff to turn it on for you. For details, please pay attention to China Telecom Guizhou customer service***. Customer service 101 will answer for you.

Hello. If you turn off the Internet function of your mobile phone, you generally only need to dial 10,000 or go to the business hall with your ID card to open it.

You can log in to the official website of China Mobile and click on the right side of "Phone Bill Inquiry" - Bill Inquiry or "Detailed Bill Inquiry" to check your consumption.

If you have any questions about the fee, you can contact the local 10086 for verification.

Do you mean that in addition to the 78 yuan ** tariff, other money has been deducted? For the money other than 78 yuan, you have to figure out: whether it is deducted because of the use of traffic, it may be a voice call or text message!

You can call 10086 to manually consult, or check the deduction details online!

You have used a fee other than **. It's best to check with the network.
