Do you have a smart phone? If you do how often do you use WIFI? WIFI works weather or not you have cell service,meaning you could purchase a smart phone or use the one you have and use SKYPE or Google Voice,or any of the other voice Over IP apps out the on your smart phone.WIFI allows you to surf the web with no charge even if you have a cell plan,so why purchase unlimited data unless you are on the road constantly? Why purchase cell service at all with WIFI hot spots becoming more and more popular? Personally I use SKYPE,$2.99 monthly for unlimited land line and cell phone calling US and Canada. using iphone 4, I installed the SKYPE app ,calls only work in WIFI hot spots and at home where I have WIFI. I keep a back up pre-paid phone about $10 mo for emergency or quick conversations.SKYPE forwards all calls to my prepaid. $13 per month I pay for my cell , txt, and data usage including my SKYPE subscription and my pre-paid phone. What about texting? use a free text app in droid or iphone, they're out there. I use TEXTPLUS in the iphone app store (in droid too). what about gps? buy a gps,probably find a cheap one online or craigslist. Convenience? yes cell service is more convenient,I can't have long conversations on the road unless i pull over to a WIFI spot (McDonalds,Burger King,Panera Bread,Star Bucks,Home Depot,Lowes,Libraries,Amtrak Train stations,Bus Stations,Airports) PRO's? however if I hit a hot spot I can talk a long as i want for free,at home I can call any where any phone for free using my WIFI. Give up my cell phone? Don't have too,you can combine SKYPE with your service,then reduce e your service and your charges! Bottom Line---i used to pay $89.00 (not even discussing overages,taxes,and fees) a month,now i pay $13.00 a month,it takes more discipline but I love the savings. Bottom line, Cell companies are losing customers and reducing prices because they know the trend,the WIFI trend. Cities like NYC are already discussing putting in massive WIFI networks starting in downtown areas. Many restaurants,companies,services,and schools have public WIFI. While it is a challenge many times finding public WIFI,it is becoming more common,buses,airplanes,and trains now carry WIFI for the public, WIFI hot spots are becoming "the cool thing" and will continue to grow,as will that cell bill.
