Man tell them to switch to T-Mobile anyway, she can get an iphone still. They will pay your ETF fees as well. They can even trade in the phones they have now to them. I just went and put my gf on my plan, they're doing like 4 lines with 2.5 gb data for $100. It doesn't include your phone subsidy but that's only $20-$30, so it'd probably still be cheaper than what you have now
Yeah. 2.5 GB is enough for my three family members combined. I'm not sure how much data I really use, though. When I had CM and had poor signal, it was barely a gig. Now on stock and getting decent 4G in my house, I set twitter to sync all images and tweets every 30 minutes, just to use data. lol
So I'm at 7.5 GB as of yesterday, I think. Realistically, I don't read it all and WiFi is plenty fine at home.
My dad won't be bothered to switch. He's pretty stupid with money, so long as he has it. He switched from a regional carrier, US Cellular, to Sprint because my sister wanted the iPhone almost three years ago. He got one too, despite still just using it to make calls. He even insisted on an iPhone again when I told him to look at the S6, G3, etc.
So there's no talking him out of it. When it'll be my money, I'll be an uber-Jew about what service I get, but until then, it's whatever. He's not out looking for the best deal.
