Apple Text Links


"The sms scheme is used to launch the Text application. The format for URLs of this type is “sms:<phone>”, where <phone> is an optional parameter that specifies the target phone number of the SMS message. This parameter can contain the digits 0 through 9 and the plus (+), hyphen (-), and period (.) characters. The URL string must not include any message text or other information."

An undocumented use of the SMS scheme was sent to us by Jonathan Balley:
You can use the undocumented:
sms:/open?address=<a number or iMessage address>
which allows for multiple recipients (notice: ?addresses=):
sms:/open?addresses=<comma seperated list of numbers/addresses>
