How to send text messages on mobile phones? It's blank. Thank you.

If it's a short message, and the information content is lost due to network reasons, send another one. If all the articles are blank, then ask customer service, I don't know! Follow-up: I sent a few blank messages and I don't know why. Answer: It should be a network problem for the time being. Has it been restarted? If it can't be restarted, consult the business hall or repair shop. Q: Restart it, too. I don't know what's going on. Is it a system vulnerability? Answer: impossible. There is a network problem or the machine itself is out of order. It's best to go to the business hall for consultation and ask: thank you. Answer: Please adopt it. Thank you.
