No SIM Inserted on LG G3 D855

Hi guys,

I'm using LG G3 D855 model with stock lollipop ROM. Currently i'm experiencing a pretty annoying bug involving my SIM.

My device seems like rejecting my SIM, when I turned it on with my SIM inserted it doesn't recognize the SIM. But when I test it with my friend's SIM it worked normally. The thing is when I tried my SIM on my friend's phone it also worked normally. My friend's phone is exactly the same as mine (LG G3 D855). I also tried with 3 other phones which have a micro SIM and have the same result.

So my conclusion is both my phone and my SIM is working fine, but when both of it come in contact the device is rejecting my SIM.

I have changed my SIM card twice to my operator and it only worked for 3 days (LTE SIM) and 8 days (3G SIM) before experiencing the same results again.

Any solution guys? It's pretty frustating to have changed SIM every week.

Thanks.
