Why can the delivery man send me a text message?

This situation about you can only be caused by one reason. It's that someone else filled in the wrong customer's phone number when ordering takeout. Fill in your phone number. When we order takeout, we need to reserve the customer's phone number. This phone number was left by the customer himself and filled in by himself. The general takeaway platform will not confirm the accuracy of this call in advance. So when a customer places an order. The backstage of the takeaway platform will send a message to the phone reserved by the customer. Your situation is probably because the customer left the wrong number. So I sent some information about takeout to your mobile phone.

Another possibility is that your mobile phone number is new. This mobile phone number has been used before. Which means the former owner of your mobile phone number. Order takeout on an APP. I have used your phone number as a reserved number. The number reserved later has not been modified. In other words, after he ordered takeout, the number reserved after ordering was still the old number, which is your number. So the takeaway platform will also send you a message.

But in either case, as long as the takeaway is not what you ordered. You didn't order it yourself. Ignore him.
