Here's my story, my wife had purchased a new note 3 from some person on Facebook well it turns out the phone is unlocked and doesn't get 4g LTE, if the phone gets 3gh+ will it affect my billing? Currently I have unlimited data plan through AT&T. Is there any way I can get the gps or weather app to work on her phone? Also she noticed the speaker is very low. When we were talking she could barely hear me. I feel so bad for her because all she wanted was this phone and now I'm afraid she got scammed. Any help will be very much appreciated.
