There are however significant cons to the solution - it is not a case of the eSIM being the best solution for consumers and I certainly wouldn't be the only person who would hate to see the eSIM become the norm. It becomes a means of lock-in that could remove customer choice, and Apple have their own agenda for wanting eSIM to become the de-facto standard. It could very easily allow them to tie service to Apple - where Apple is your telco provider and your only option for an iPhone is to buy an Apple subscription service for use.
None of the cons of eSims are exclusive to eSims, so are a bit of a red herring. Apple or Samsung could lock you into their provider at any time, they control the software after all.
eSims don't make that any easier or likely.
eSims just remove the *need* to use a plastic SIM card, everything else is the same on the phone side of things.
