balatro Is there any scenario (with or without the jmp adapter) where those two imei can stay protected/hidden from the service provider?
Cellular providers have spent many billions of dollars/euros/etc. rolling out networks that include lots of device-tracking features. Some features, such as precise location for emergency calls, or blocking handsets that are reported as stolen, are legally required in some countries.
It isn't feasible to trick cellular providers into accidentally offering a privacy-respecting network when device tracking is so thoroughly built in.
