Overview

A QR code with embedded phone number and message. Scanning it opens the messaging app ready to send. Great for preventing number typos or sending specific codes.

Capabilities

Pre-fills destination number and template text to reduce communication latency.

Use Cases

Useful for booking confirmation, arrival notice, and onsite coordination workflows.

How It Works

Builds `sms:` payloads with body parameters for native messaging app handoff.

Cautions

Body parameter interpretation varies by OS; validate behavior on target devices.

Technical and Practical Benefits

iOS & Android Compatibility

SMS QR behavior can vary by device and app. This tool uses the widely compatible `smsto:` format and focuses on reliably opening the compose screen.

Technical Specifications

                Schema: `smsto:<phone>:<message>`
Note: Message-body handling varies by OS/app, so scan-test before publishing.

FAQ

Will the message send automatically?

No. It only opens the compose screen. The user must tap Send manually.

Is the phone number/message uploaded anywhere?

No. QR creation runs locally in your browser, and your input is not sent externally.

Why isn’t the message body pre-filled sometimes?

Some devices/apps don’t support pre-filling the body reliably. In those cases, only the recipient may be set.

What happens with long messages?

Long SMS messages may be split into multiple parts depending on the device and carrier behavior.

How should I format the phone number?

Digits-only is usually safest. For international use, include a country code like `+81...`.

Can this open LINE/WhatsApp instead of SMS?

Not in this mode. Use URL mode to encode a link for another app.

Is it okay to post this publicly?

Anyone who scans can open a prefilled message. Avoid embedding sensitive information in public postings.

The SMS app doesn’t open after scanning

Support depends on the device and scanner app. Try another scanner, or provide an alternative (like a URL link) as a fallback.
