Get hold of a 606 number
You can reach a 606 number in two different ways. With its plan, a provider hands out a new number, picked at sign-up from the numbers that provider already holds in the code. Sellers post numbers they already hold, often ones with a pattern, and charge a one-time price; after that you transfer the number to a provider.
