However i have recently started a Business and i need a seperate line for the business ( i have been using my personal phone for Business and it is constantly Blowing Up even more so i need a seperate line indefinitely ) I have heard Boost Mobile offers an Unlimted Talk & ( I Believe Text ) for $50 per month although it just might be ( Unlimited Talk for $50 per month ) in then i saw this phone at walmart an unlimited Plan for $45 there is probably many more out there anybody have any Facts about the good and Bad about these Service Providers or their Plans and the phones etc? ( Remember all i need is Unlimted Nationwide Talk for the business all i need is $50 per month or less THE LESS THE BETTER OF COURSE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! ) ANY HELPFUL ANSWERS ARE VERY VERY APPRECIATED THANKS PEEPS
