Send a text message to someone, indicating that it has been sent.

Unicom users can't send and receive short messages on their mobile phones for the following reasons:

1. Mobile phone settings Check whether the SMS function is turned off, whether the SMS center number is set correctly, and whether the SMS inbox and sending box are full.

2. Busy service, holidays and other short message sending peaks will cause the system to be busy, so you can pay attention to short message sending later.

3. SMS blacklist is included in SMS blacklist because the information sent by mobile phone contains illegal wording in telecom industry. If it is necessary to reconnect, the owner needs to bring a valid ID card to the business hall to cancel the SMS blacklist.

If the above methods fail to solve your problem, you can call the local customer service hotline 100 10 and transfer to the manual desk. After registration, someone will follow up and deal with your problem.
