Can the tray jut out of the phone body a little?

haiz... maybe u can look for help at DirectD... see pay them, they will help or not...
official SC is at Amcorp Business Suites... look for SEMS services...

you inserted an empty sim adapter in right?
if yes DO NOT PULL the sim tray out. the sim transistor or whatever you called it is stuck on the empty sim adapter. send it to the service center. force pull means bye bye to your phone.

happened to me before on my Lumia, i was thinking it's easier to put the empty adapter in the sim tray so it will not get lost easily. luckily i didn't force pull it out and sent it to a service center.

good luck. i know how it feels. new phone. swap. stuck. life.

OK this is not tested but here is what I think is happening. The contact pins have make contact with the void part of the adapter. Thus lodging them self in when you try to pull out.
A very thin piece of hard plastic maybe 0.2mm thick cut to fit the size of the tray, longer of course plunging into the sim card side might free the pin and enable you to pull it out.
Try at your own risk, but I doubt a thin plastic can do serious damage.
