My Unreal Mobile phone number was one that I used as my primary phone back in the Ring Plus days.
I don't use it a lot, anymore, but there are still some people who continue to contact me with that number-- so I didn't want to just let it go into the ether because I elected not to sign up for a Ting plan.
Before I went to bed I sent an email to Tello from my PAYG account asking if they could port that number in and discard the number on my PAYG account. (It's a junk number I don't care about.)
When I woke up it was already done. No follow up calls or emails required. One simple email and that was it.
I know that we all realize that Tello has amazing customer service, but they actually make it look easy.
The only other customer support I know of that's that good is Ting.
Mint is pretty good, but they're not in Tello/Ting territory.
Since I was porting from Ting to Tello I had the two best organizations taking care of the handoff. Gotta love that.
