Content test of received SMS

I think it's really dangerous, but don't worry too much. The probability that you get caught is lower than 10%, although this is a bit atypical, because generally speaking, if the message contains a virus, the received message should be a download link or something. After clicking, a virus will be installed by default, your message will be sent back to the sender (secret), and you will be prompted to reply to the message. The key problem is that you received a string of characters instead of a link. In other words, this is a message, not an installable program. You won't get caught if you don't pretend. However, I suggest you scan it with software like Mobile Guardian, and delete this message and don't reply. If you see a strange message in the future, and you are not sure about the source of the message, just delete it and regard it as not received.
