SMS Links

The sms scheme is used to launch the Messages app. 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.

The following examples show strings formatted for Safari and for native apps.

• HTML links:

  <a href="sms:">Launch Messages App</a>

  <a href="sms:1-408-555-1212">New SMS Message</a>

• Native app URL strings:

  sms:

  sms:1-408-555-1212
