China Unicom can make a phone call, but why can't it receive information and send it out?

1. Check the number of the SMS center first. Remember to add +86 in front, these three things. \x0d\2。 Call 100 10 to check whether the SMS function is enabled. \x0d\3。 Can you get the message? If you can accept it, it is not the first two questions. This is mostly because there is something wrong with Unicom's data. We have to wait for 100 10 to be processed in the background. 100 10 will usually reply you within 48 hours. You can call again if you don't reply, so this is an escalation complaint, and they will be very concerned about your affairs. If you are really angry, you can directly call the Beijing highest complaint hotline 0 10 10065438. Generally, you threaten them with 65438. \x0d\\x0d\ quoted from the reply of lishanshimeinv.
