Well, me and my grandma are on the same plan, or a family plan, whatever. We both have iPhones so it's a bit more pricey than just a regular ole' phone but I don't think it's too bad. I think it's like $150 a month for the two of us... that's with unlimited texting, unlimited data and all that stuff that comes along with the iPhone on both of our phones. I think it's something like $20/month for unlimited texting and my data plan is $30/month for unlimited. I am on AT&T and have been for a while and always happy with it. Was on Verizon before but did not see a huge difference. I've always had great luck w/ AT&T's customer service
