SMS URLs

1 min read Original article ↗

Did you know there is a URL scheme for sending an “SMS” or text message, similar to mailto:? SMS URLs are defined in RFC 5724 and are formatted like so:

sms:<recipient(s)>?body=<body>

Here's a bunch of test links with different scenarios you can try on your mobile phone:

Annoyingly, it appears that as of today Apple doesn't implement RFC 5724 correctly for multiple recipients. The first URL won't work on iPhones, but will work on Android. Only the second URL will work on iPhones (and there's not much public explanation as to why that might be).

I used this discovery to create a small client-side application for drafting long SMS and iMessage messages on your computer to be loaded into your phone via QR code.

Wow, you made it to the end!
