So there are possibilities here.
First of all, if you are correct that you have received and sent messages while in airplane mode, then you have to have another network connection somewhere and the most likely (only one likely) would be Wi-Fi, which can be turned on in airplane mode.
You say that you sent and received SMS, which is a specific protocol. That should be impossible. But if you mean that more generically and that you sent a text message and received a text message, there are other protocols that can use Wi-Fi. Like RCS.
And it is possible that you are using a VoIP like layer for your texting if that is enabled by your phone and carrier, etc. SMS over IP gateways can be used, but you would certainly know if you would set something like that up.
So chances are, you are using a messaging app that will fall back to IP texting one way or another, or you're using a protocol that does that natively like RCS.
