If you get this phone, wait until the Marshmallow 6.0.1 update comes out before you update the OS. Otherwise, you could have issues sending and receiving MMS due to a known bug (6.0.1 will address this issue)
Thanks all for the info. I got it from best buy mobile. Was able to keep my old plan and its running awesome. No problems like the aforementioned MMS that red mage said so I must've gotten lucky. Thanks for all your help.
