help I got my sim card stuck in the slot after the tray broke

First off you could buy a sim card tray with shipping fir around 6 dollars. Now to fix the issue. Watch a few videos on YouTube about disassembling the phone. Be careful taking the back cover off because they are super thin. Have a dish towel under the phone in case you crack the back it will leave tiny pieces of glass. If you damage the back to can buy a new one for around 5 dollars. Tear down the phone until you can see the motherboard and battery. Disconnect the battery. Get some alcohol and acetone and some qtips and slowly clean the glue off of it. Get out the sim card which you should replace. There is a possibility that the sim card tray might need replaced but there is no way to know until you try this. These are the parts you will need. This is one of my parts suppliers and if you sign up for an account you get a discount. The back cover comes with adhesive installed already in case it gets damaged. Ifixit sells the back cover for all most 50 dollars because it's original but you said you are low on money, the only difference is the back cover will not say Samsung.

I can't guarantee this will work and you take responsibility for the repair that you are doing.
