First - Your Sim card is only to contacts storage.
Second - You should check your internal phone storage and then add a Micro SD card to upgrade that storage capacity, Anyways there’s some phones that we can’t transfer the apps to the removable storage(Micro Sd) but you could try. Settings - Apps - Click on the app - Move to SD Card.
This is the best i can do with your infos. You should consider upgrade your phone,remember to always check the internal storage should be at least 32Gb.
