Hello everyone im new here. I had a problem in the LG G5 Sim holder tray the gold pins was damaged and i wanted to replace...

You can either buy tools. Watch a similar video as i do to fix but the danger will be to make more damage if youre not careful so better send to repair shop. Its easy for them to put a new sim holder for work sim. Prices are many. Can start from 46 euros and can be until 150. Better you must contact and search before you do anything else.
