Won't cost to keep it there true, but the port to Google Voice is $20. Not sure if TMobile will charge you anything to Port In, or if your current landline carrier will charge you to Port Out or a termination fee. You can check portability from you landline to TMobile here, but keep in mind that if you Port Out from TMobile to Google Voice or anyone else for that matter, it will terminate your plan with TMobile and you may be charged an early termination fee if you're under contract. If you want to keep your TMobile phone you'll then need another plan.lbmofo wrote:If you want to keep your old number in the meantime, you can go the route of Google Voice and at least park your number there for free until Ooma can take in your number.
In hind site, I think I would personally take the new number from Ooma and send out a email to everyone, or phone anyone who doesn't have email by phone before I made the switch. However, check what the toll charge might be for family and friends who will contact you often with the numbers you have available from Ooma. I know that there were some complaints from people in the Canadian prairies who switched without checking carefully and then found out that their family and friends would all have to phone a long distance number to reach them.
My secondary number is in the US so my parents can phone me without paying LD charges, but I couldn't get a number in their calling zone, so it wouldn't be completely free which is what I really wanted. I was able to get a Google Voice number in their calling zone that forwards to my secondary Ooma number.
