SMS QR codes: message in one tap
When SMS beats a messenger, how to write the text and where these codes work best.
How it works
The code opens the messages app with the number and text filled in. Sending always needs confirmation — the code itself sends nothing.
When SMS beats a messenger
- Older audiences without WhatsApp or Telegram.
- Places with weak mobile data: SMS goes through on minimal signal.
- Voting, opt-ins and services that only accept SMS.
Writing the message
Make the intent obvious: “Please book me the next available appointment” rather than “Hello”. For opt-ins use the keyword your system expects.
Say so next to the code if the message is charged. An honest “standard rates apply” builds trust.
