MrBill, my carrier is Cellcom. Which is @cellcom.quiktxt.com. I have no idea if this is a SMS gateway. How do I check for that? However, inspired by your SMS comment, I scrounged around and accidentally found a workaround.
Workaround (or actual solution) found! When using the above "@cellcom.quiktxt.com" I get the messages without CRLF. But, I discovered Cellcom has another message method, which is "@pics.cellcom.com". When I use that, I get the attached result on my phone. I have no idea why it works. But all of it is actual text, not pictures. This includes the
"This is
a message
to test..."
portion I wanted formatted.
