I think what concerns me with this is that at the least, with a sim, you’re garuanteed flexibility to swap. Let’s say you have a backup device (which cannot connect to internet) and you’re on a hike or far trip for the day - your phone happens to break. How are you able to switch to the backup device that has no sim available now to place into the device (since ESIM) or wifi available / and since it’s not connected to data you’re unable to activate it?

I know that’s an off case scenario but I’m not anti ESIM - I think learning more about the technology and convenience is really progressive and adaptive. But I do think there’s benefit to having a physical SIM - there’s just more you can do with it. I like the stability in knowing the physical chip controls the phone service rather than relying just on being locked down to the device managing the electronic sim - in event of an emergency, accident etc.

Personally, I think it will be a hassle especially for those who travel and want to switch SIM cards out of devices. If we become locked into E-SIM (if that is the wave of the future) let’s say you’re traveling internationally and don’t want you use your native home plan as it’s much expensive for travel roaming costs. I usually purchase a new sim at the country im visiting/at the airport and pop it into the phone. I know SIM cards can be tedious but they are convenient. I feel removing this choice and making it all “ESIM” while great will then cause other communication challenges and needing to make arrangements if you’re planning to phone swap and/or travel with an out-of-country SIM.

I myself like to switch sometimes between my iPhone and Android device (though it’s been a bit since I’ve done that, the option is still there whenever I need it).
