Why can't I send text messages on my new China mobile phone card?

1. Check the number in the SMS setting center. This number is provided by the mobile company. You can call the manual station 10086 for inquiry and reset. The simple detection method is to plug the mobile phone into someone else's mobile phone and see if you can send text messages. If you can, it means the number of the SMS center. 2. Has the short message been sent in groups? If you send text messages in groups, it may be that a large number of text messages are sent, which leads to the blocking of text messages. You can call the manual service desk at 10086 to help unseal.
