How do I check the status of my 10DLC (A2P) registration?

After you submit the registration, you can track its status on its tab. There is a progress tracker with steps one, two and three, and a list of all the brands you have submitted with the status of each.

A submission normally starts at internal pending, which means the Votel team is reviewing it first. Then it moves to submitted, and then to approved or not approved.
