What is an SMS QR code?
An SMS QR code opens the Messages app with your number and a ready-to-send text, like “JOIN” for a text club. People tap Send, so you get the message without anyone typing your number. It works with the built-in camera on iPhone and Android.
What’s inside the code
SMSTO:+14155550100:JOIN
SMSTO: is the format iPhone and Android cameras turn into a prefilled text: the number, a colon, then the message.

What happens when someone scans it
iPhone and Android open a new text message to your number, with your message in the box. People choose whether to send it.
Free static code
SMS codes are static: the number and message are printed into the code. For a number you might change, or to count scans, a dynamic WhatsApp code does the same job and stays editable.
No watermark, and RelyQr codes never expire, on any plan. Static vs dynamic, explained
