I have a F&F Family 800 I'm trying to trade for a sero plan. The plan starts at 70.00 and the first additional line is free, then 10 dollars for each additional. 5 dollars for data and 2.50 for texting extra per line. With the corp 25% discount I pay 52.5 plus extras for two lines. Only problem is you can't get any new smart phones with 4g same as the normal sero plan.
