Can parents who buy train tickets receive text messages?

This is very strange.

Both E Long and 12306 can only receive short messages by themselves. When I bought a ticket for someone else on 12306, I specially entered the passenger's mobile phone number, but after the ticket was purchased successfully, the passenger didn't send a text message, only I received a text message.

It seems that your father-in-law is an expert and can intercept your message.

Is your father-in-law a hacker?
