Create an SMS QR Code With a Prewritten Message

An SMS QR code can open a phone's messaging app with a recipient number and message already filled in. It does not silently send a text. The person scanning still reviews the draft and chooses whether to send, and different phones may handle the link differently.

Set up a prefilled message

1. Open the QR code generator and choose its SMS type.
2. Enter the recipient's number in the format they expect, including country code when useful.
3. Write a short message that makes sense on its own, such as “Please send me the event schedule.”
4. Scan the preview with a phone, check the recipient and draft, and confirm it opens the expected messaging app.

The tool creates an sms: link with a body value. It encodes the message for the link, but the receiving device controls which app opens and how the draft appears. Test both the QR image and the actual scanning flow before printing it.

Use clear wording and a real test

Keep the message short enough to read before sending. Avoid putting private data or account credentials into a prefilled message: anyone who scans the code can inspect the text. If recipients need to personalize it, use a neutral prompt rather than a message that assumes their consent.

Test on an iPhone and an Android phone if the audience uses both. Check that the number is correct, punctuation survives, and the app shows a draft rather than sending automatically. A scan that opens a compose screen is the intended handoff, not proof that a message was delivered.

Print the final code at a usable size

Generate the PNG after the number and message are final. Scan the downloaded file from the size and material you plan to use. A longer message creates more QR data and may need a larger printed code. Strong dark-on-light contrast helps phone cameras distinguish the modules.

SMS QR codes are static. If the recipient number or wording changes, make and test a new code, then replace old copies. Do not expect to edit a code already printed on a poster.
