I'm trying to install a sim card into my Sentinel, following the instructions here: https://docs.modalai.com/sentinel-user-guide-connect-network/
However, I can't see the sim slot at all as the plastic housing obstructs the view. Also my drone seems to differ slightly from the one in the instructions. (e.g., there were no screws for the chirp sensor). I also need to know what size sim card it takes. Would appreciate any help.
Thanks
