`get_new_number`Add a new US phone number to the user's ExpressNumber account. This changes their account and may count against their plan, so ask the user to confirm first, in this conversation, including the area code they want. Never call it on your own, and never call it again to retry without asking. It follows the same plan rules as the website: if the account has no plan, is at its limit or needs attention, it returns an error with a link to fix it. The number receives texts and calls; it cannot send texts or place calls.	Add a new US phone number to the user's ExpressNumber account.
