Why didn't you reply by texting 10086?

Well, you'd better call the manual service (call 10086 and follow the prompts step by step). Because the business of sending short messages to mobile is not necessarily sent to the number 10086, many of them are other things, such as 1065…

In addition, the SMS sent must be sent in full accordance with the regulations (even a punctuation mark can't be wrong), and many services are code names (for example, if you don't want GPRS traffic to peak, you can't send it to him: I don't want GPRS service. This is totally unacceptable. )

You can also call the human service and ask him to tell you how to send text messages.

Another one is, do you have a program called "SIM card application" on your mobile phone? If there is, you can get it in this program (SMS is still free)
