Hi Phenyo,
You could try using compressed air to get it out, however, if it's truly stuck to the point it won't come out even with tweezers, then it's probably of little use.[br]

If sounds like you may have to open it up and gently push the card out with a needle or tweezers without damaging the reader. Here is a video that shows you how to do it: [link|https://www.youtube.com/watch?v=qD21KNi7umM|Samsung Galaxy S9/S9 Plus SIM Card Removal (When Stuck) - YouTube|new_window=true].[br]
If you don't want to perform the repair yourself, I am sure any phone repair shop near you would be happy to do it.
I hope this helps, let me know if you have any other questions :)
