Okay, thanks for the reply!
I wasn't sure because I was going off of this output from the GlobalPlatform tool when listing my loaded applets. I thought that it might be possible because none of them were listed as default, but it could just be an incompatibility with the GP tool when reading the SIM card.
Do you think it would be possible to export the USIM application and make changes? The concept that I am working on needs to be a SIM javacard and 5G compatible.
