ST4SIM-110M hi! can i put ST4SIM-110M into androd phone ? and how can I communicate with eSim?

About ST4SIM-200M, how do we know the IMEI of the ST4SIM-200M components we purchased?

I would like to use TESEO-VIC3D as a replacement receiver in our monitoring products. Ideally this would have exactly the same footprint. What inputs can be left O/C? We use the UART (pins 20 & 21) and 1 PPS (pin 3).

I have received a response on this which mentions pins 1, 6 & 15 as O/C. What about nReset (pin 8) and AntOff (pin 14)?
