I know my dad uses a prepaid pay as you go type phone cause typically say, 85% of the time him and my Mom are together so they don't really need two phones. I just know to dial my mom... Half the time he answers anyways. The alternative phone for the summer is something I'll toss their way though to keep in mind during their research.
Funny part for me is if I leave my house without my phone the only thought that crosses my mind is "crap, hopefully the car doesn't break." LOL, other then that I could care less about the phone. Shoot I've got a voicemail on it still from Thursday that I still haven't listened to! HAHA I hate the fact I pay $65 a month for talk and text yet I only use about 1/3 of my allotted minutes yet I already have the cheapest plan Verizon offers.
