Will the SMS be sent automatically?

No. The QR code pre-fills the message, but the user must tap Send to actually send it.

Is there a character limit?

Standard SMS supports 160 characters. Longer messages work but may be split into multiple parts by the carrier.

Can I use a short code instead of a full number?

Yes. Short codes work in the sms: URI just like regular phone numbers.
