Reddit:

My iPhone was stolen (central Europe) about a week ago and yesterday, the number I had set up during the “Lost Mode” process received a text message saying the phone was switched on and telling me to reply with the options to lock, erase or find the iPhone.

I suspect most folks reading this would never fall for the phishing text messages. But what this walkthrough offers that makes it worth reading, at least to me, is the link to the support document with details on reporting phishing to Apple, as well as the link to iCloud.com/find and the image (at the very end) showing what a real Find My email from Apple should look like.
