A:Answerif you get the unlocked you'll have the ability to switch carriers. much more difficult and not too sure if its even possible if you choose verizon and want to switch. the mm-wave is the unlocked too
A:AnswerI don't know anything about sim card models but as far as I know you should be able to use your old sim card and insert it in the new phone, that is what I did. It should if you buy a unlocked phone but I would call Best buy or Boost Mobile.
A:AnswerI went and they told me the calls and messages were working but that their internet was still not supported on their network. He told me that my phone will eventually be added and that it will start getting data randomly one of these days or weeks. He didn't give me a specific date. Its not a big deal for me though since I have wifi but still, kinda bad.
A:AnswerHello Sandman137, great question! This phone has a 164.0mm (6.5" full rectangle) / 161.6mm (6.4" rounded corners) main display size. ^Elizabeth
