I don't really know how SIMs work but is this not a good thing ? Is this not possible to slowly start getting rid of SIMs and only use smartphones' antenna and something like credentials in order to connect to the GSM network ?
SIM cards take space and when you change carrier, they need to send you a new SIM, you have to change it, it takes time, etc. Having a soldered SIM that you can reprogram seems to me no different than having a SIMless device that you can connect and disconnect from any communication app, just like you can already do with any smartphone for any app, except this time it is to connect to the GSM network.
I'm probably missing something as I'm not really knowledgeable on that matter so enlighten me, please.
