How to exchange APDUs without rooting the device?

I have written an applet on a sim card and successfully installed it on my sim. Now I want to send/receive APDUs to my sim card applet using an android application.

Some libraries (e.g. Seek) need rooted devices and do the task but I don't want to root devices. Is there any android libraries to interface my applet? All I have found is applications to use NFC or Bluetooth to send or receive APDUs to contactless cards, but I need to interface contact sims inserted to mobile sim card slot.

Appendix 1:

These are all applets existing on my USIM (output of GPShell list function):

Since Android 9 there is android.se.omapi package providing such access (implementing SIMalliance Open Mobile API). For older devices supporting OMAPI, see e.g. here, here, here.

To get access to your applet there has to be an ARA-M applet on SIM configured to allow your application to connect to your applet (there is a MIT licensed implementation available here and a special all-allowed implementation here).

Access configuration can be performed with GlobalPlatformPro.

Disclaimer: A lot has changed since I was dealing with this so please do validate my thoughts.

Good luck!
