Are you interested in passing additional information about your subscribers, like what mobile phone carrier they're using, in something like a query string within your SMS message? If so, you're in luck as that's what our Carrier Code merge tag does.


  1. When creating a message, use the merge tag {carrier} in your message.

  2. That's it, finish your message as you normally would, then send/schedule/save. When someone receives a message with the merge tag {carrier}, it will be replaced with their carrier, so for example, if the user has a T-Mobile subscription, their message will read "T-Mobile" for the tag.
