Frequently Asked Questions
Which SMS format does the QR use?
We use `SMSTO:number:body` — the format supported by iOS Messages, Android Messages, and Google Voice. (The older `sms:number?body=…` syntax is less reliable across devices.)
Can I include special characters or emojis in the message?
Yes — emojis and Unicode are preserved in the QR. Long messages encode to larger QR codes though, so keep the draft short (under 160 characters is ideal for a single SMS segment).
Does the user need data/Wi-Fi to send?
No — SMS is carrier-based, not internet-based. Your user can scan and send even on airplane mode with cellular on. That is part of why SMS QRs are so useful in low-connectivity scenarios.
Can the user edit the message before sending?
Yes — the phone just opens the Messages app with the fields pre-filled. The user sees everything before tapping Send and can edit either the recipient or the body.
Will it cost the scanner anything?
Only whatever a normal SMS to that number costs on their carrier plan. There is no added cost from the QR itself.
