For that phone on a Share Everything plan alone, you could have a $30/month line access fee and $10/month for 700 minutes without any data or texting included.
Keep in mind if you DO use any data on that plan, you would be paying $1.99/MB. If you send/receive any texts, you would be paying for each one.
I don't think this will work.. I have a family plan 700 min plan with 3 lines.... 2 lines have the old unlimited plan and now the 3rd line is the Intensity II which has me add at least the $10 plan (no choice for no plan) ... Then I have $30 unlimited texting that covers all plans
