An old man asked to send him a message.

Hello, my friend, I'm glad to answer your question! It is probably a lie. You think, now the society is chaotic, and there are many tricks for scammers! He uses your mobile phone to send text messages, and it is very likely that your mobile phone will have no money after sending them! This is the best result. What if they are a fraud group? Use the old man as bait to defraud passers-by's sympathy, because people think it's normal that the old man can't send text messages, and then you send text messages, and their mobile phone numbers are locked, and then ... so I suggest you ignore him in this case and let him go to the police station for help. If he does dye you, you can threaten to use the police. I wish you happiness!
