SMS Onboarding

We know you can't wait to get started sending SMS messages but we still have a little bit of work to do to get your business registered so the telecommunication carriers don't filter your messages or assess fees and fines for misuse of their platforms.

Before you fill out this form you should have placed an order for messaging service and worked with our team to select a phone number to use for sending your SMS/MMS messages. While you can go ahead and submit this form now, if we need to port a number for use that will need to complete before we can complete all registration activities. Depending on many factors this entire process could take only a few hours or up to a handful of weeks. We'll keep you in the loop the entire time!

Lastly, we do need all the information on this form submitted at one time. Please review what is being requested to ensure you have everything you need. This will ensure we can get your messaging service up and running as quickly as possible!
