Signed up with PhonePower, picked a number from their list of availables nearby, configured with Obi Device - easy as pie. Except - they had already issued the same phone number 1 week prior to another customer, so they called and said I had to give it back and get another. Instead I paid attention to the bad vibes from this and canceled. I will give Anveo a try.
You should have used the situation to your advantage and asked Phone Power for a number that was either even numbers / multiples of ten / mirrored in some way or a combination of numbers you liked or people could more easily remember.
