Is the message required?

No. You can encode only a phone number so the user types their own message.

Does scanning send the SMS automatically?

Usually not. The messaging app opens with fields filled; the user still taps Send.

No. Generation is client-side. Your number and message stay in the browser for creating the image.

Use a full country code. Delivery still depends on the scanner’s carrier and messaging plan.

Your data never leaves your browser — all QR codes are generated locally.

An SMS QR code encodes an sms: link with a phone number and optional message. Scanning opens the messaging app ready to send.

Common uses include contest keywords, appointment reminders, short support lines, and campaigns where texting is easier than calling.

maintool builds the SMS payload and QR image only in your browser. Numbers and message text are not uploaded for generation.

Keep pre-filled messages short — some carriers and apps truncate very long bodies. Use clear campaign keywords when you need to sort inbound texts.

Static codes embed the message you choose at generation time. Update print materials if the campaign text changes.
