Suspected DWM156 D-LINK USB Adapter Mainboard With Leaky Transistor

[LENOVO-A880]

Hello Badcaps.net,

Does anyone has any clues what the value of this SMD transistor(PIC01). I suspected it's a leaky transistor where the mainboard of this DWM-156 DLINK USB Adapter failed to read the SIM card whenever I tried to use it to access the internet service. BTW I have attached some of the photos of the adapter mainboard and other parts(PIC02,PIC03,PIC04) so if you guys have any ideas for fixing it you're always welcomed to post them here. THANKS AHEAD OF TIME..

The marking code suggests a BFQ31AR . No schematic available https://apps.fcc.gov/oetcf/eas/repor..._id=KA2WM156A3
