what is the cost of add a second phone to my plan?

Hello Jeff, 

At this time our plan options don't allow to add additional devices to your current plan. Each device would require their own plan for usage. Our MyPlan service allows you to build the plan you need to suit the Voice and data usage required for the phone. I've provided our MyPlan builder link here for you to review our current options.
