5700 can't send text messages with the number in the booth. 100 10 to send. What's going on? I'm a Unicom card from Nanning.

Hello, according to previous experience in dealing with similar problems, I'll tell you a solution:

First of all, you should check whether the message center number set in your mobile phone is correct. Guangxi Unicom should be set to+8613010591500.

This can't be exchanged for something else, otherwise it won't work. Also, I suggest you call 100 10 to the manual station (it's not perfunctory, it's really useful) and ask to refresh the data (the customer service knows), but then turn it off and on again, which can basically solve the problem!
