Sounds like your family has a legacy Unicel plan. Even though VZW acquired Unicel customer base, customers kept their Unicel plans and phones unless they upgraded to VZW equipment. Also sounds like you could all benefit from current VZW Nationwide plans and VZW phones. VZW Customer Care can do a plan analysis based on everyone's usage and recommend the best plan for you, and hopefully save them some $ while getting everyone up to date features like free nights and weekends and unlimited mobile to mobile calling.
