Build your plan
Both plans answer every call, 24/7, on your own number, and ring your cell for real emergencies. Pick one, add a second number if you want it, and you are done.
Both answer every call, 24/7, on your own dedicated number, and email you a summary after each one. Month to month, cancel any time.
On top of either plan, month to month, same as the plan. Drop any of them later by replying to your setup email.
