I haven't done anything yet, but I don't see this specific process outline anywhere. Would like to plan ahead to avoid issues.
1. I've had the same phone number since 1989. At some point, at least 10 years ago, we ported that number to Comcast as part of a Triple Play package.
2. I want to move that long standing number to a new AT&T mobile line. I want to keep the Triple Play, as that's still my best deal.
3. Can I let AT&T port the number, and let Comcast provide a new random number for the Triple Play line?
4. What would be the correct process or sequence to port the number with risk of losing it, without changing my current Comcast service or billing?
