Hi all sifus
I am a gn2 user with os 4.1.2
Sim card faulty and is unable to detect maxis signal.
Changed the sim card and it can detect the signal.

Back then before I change the sim card, my note 2 can hook to q signal very fast ie from basement to my condo.
After changing sim card it takes forever for my note 2 to find the signal after exiting from basement car park.
Even though it have no logo of G, E, or H I can still use the voice cause the signal bar is full. But data is a no go. And my friend cant even call me when I am on full bar.......not until I turn on flight mode on and off then onlu the phone will come back with the H or E logo.
Advise please. ..my phone koyak or a problem sim?
