Unlimited calls/text/data&wifi hotspot tether laptop $30/mo

I have had a hotspot from Freedom pop does what it is supposed to.For 3.99 I get 500MB a month,and for an additional 3.49 it rolls over every month.Also have a Samsung s3 from Ebay Think I paid about $110 for phone. $20.00 to sign up now free.I works ok the freedompop phone service is not the best but works.But every thing else works like any other smart phone.All the Apps work like any other phone service.Sprint has good service along the interstates,at my home sprint is better the ATT.
