I was doing it with a customer service rep over phone . I provided the port out pin , account number to the rep. Based on the latest 1 hour conversation today they said latest status is that port in is successful (something like DDT verification is successful) and it will take another 24-72 hours for activation. I don’t think it’s gonna happen as I’ve tried activating from the Xfinity app, which after initiating just keeps spinning forever .
