How can I repair 3G data modem board a broken USIM Slot

I un-knowingly broke the spring mechanism within the 3G Data SIM input (the "push-push insertion mechanism). Also if a repair of the module cannot be done, or is inadvisable, then where could I get a replacement 3G Modem Sister-Board for my Samsung Chromebook XE303C12-H01UK (Not the WiFi Only version, I know there is one) . To all who help, Thank you.
