Crashes, Freezes & Reboot (Need Help) N9005

Hi Guys i have re-flashed my phone with the new rom of Note3 and the problem that i was facing was it got stuck by own and asometimes black screen after downloading apps on phone. i think the reason was that it has something to do with the sim. now i hav the 4g type sim the latest one it is working far better then my old no 3g supported one so. the bug is that it is related to old sim users and i m changing my sim ASAP so i can have fun for the time i was searching for roms everyday and when i reflashed the phone and used my phone with my bro new simcard it was runing far better then the last time so please give a try
