The sim swap can be done. - I just did it.!
Brief summary:
2014 F32, originally with “route” business nav and tcb.
Retrofitted nbtevo, then used adaptor loom to connect new ATM, used BimmerUtility to code vin etc.
Removed eSIM from old tcb then soldered it onto new atm.
FULL functionality restored with MyBMW app, remote services etc..
