Okay, i wasn't going to upgrade but the thought of having a nice new phone got me, so i have my pre-order. but here is my question. I am going on vacation for a few weeks in September and i really don't want to go camping/fishing with my new phone. Do you guys think i can just pop the SIM from the note 7 back into my note 4 without any issue? With AT&T i was able to do this with my work phones, we got new ones every 6 months it seemed and that's all i did.
