SMS QR codes still earn their place: opt-in keywords, “text us the photo,” field-service check-ins, classroom reminders. The code stores an sms: payload with the number and optional body.
Write the prefilled message as something the person would actually send. “START” or “HELP tableside” is clearer than a paragraph. If you later move to WhatsApp, generate a new code - the payload format is different.
FAQ: SMS QR Code Generator
Will this send the SMS automatically?
No. The messaging app opens with the fields filled. The person still taps Send. That prevents accidental texts.
Does it work with short codes?
Often yes, if the carrier and phone allow it. Test on iOS and Android before a mass print run.
