The problem of sending text messages on mobile phones?

In communication operators, the numbers needed to send short messages are generally as follows:

China Unicom has a 13 1, 132, 133, 156 digital mobile phone number.

China Mobile is: 134, 135, 136, 137, 138, 139, 158,/kloc-0.

China Telecom PHS is: 106+ area code+PHS number.

So if the number you send is not in the above format, as you said: send a text message to 2 145 to 102344, it is very likely that you have customized some SP services. There are various services, and your mobile phone will be charged after customization. In this case, please call the customer service hotline of your operator (mobile phone: 10088) as soon as possible. Unicom: 100 10, Telecom: 10000) Turn to the manual station to check whether the related services have been customized. If it is a monthly business, please be sure to ask the customer service staff to cancel it for you immediately. After the cancellation in the current month, the fee will not be deducted next month.
