> Arguably we've become slaves to ecosystems of either Apple or Google at this point I’m far more worried about the SIM cards than Apple or Google. Did you know that SIM cards run Java? Or that they can send text messages from your phone directly to the baseband without going through the phone itself? Your SIM is probably sending data to your carrier without you knowing.

That doesn’t mean you can’t add or change your provider when you travel, it just means you do it through the user interface instead of removing a little card that runs Java and has access to your baseband.

> move everything to purely digital number porting There's a common misconception that SIM == number. That's not the case. The SIM is simply the identity of your device to a carrier. > a little card that runs Java I believe (it's now been a few years since I've skimmed the spec) that the eSIM chip can also run Java and download applets.

Sure, but the sim doesn't have access to the main CPU, main memory, storage, or sensors (without help from an app which can just as easily leak data without help from the sim) I fail to see how it compromises security any more than an eSIM.

The full portability won't be the same across multiple regions, especially internationally. Also, there is a good chance it gets tied to the device/contract you are on, similar to how the phone contracts in the US were a few years ago.

Here a different perceptive on this. SIM: Great! my phone just broke and I need to call my insurance to get it replaced. Oh lucky I saved my older phone! That is so perfect because I can take the SIM from my primary phone and put it in the older phone. viola it works! all of that take within 5 mins. Without SIM: Great! my phone just broke and I need to call my insurance to get it replaced. Oh lucky I still have my older phone... oh wait, they don't have a SIM. So I am stuck without my phone for a week and need to have access to my phone now! Wait let me see if I can open my older phone and see what I can do. turns on yay it still works... no cellular signal? Oh right right, I forgot this phone don't have SIM. Oh ok I guess I have to go through the internal app to get it over to this phone. Why this app kept failing?! C'mon I just need my phone to work because I am expecting calls for potential future job that I might get it! two weeks later with new phone at the door Great... I didn't get the job because the mobile company and insurance been dragging this long as possible. All of this might take two weeks. This is why people favors SIM because it can be taken out and put in other phone within minutes. In other side, people will be stuck without phone for a while because of this stupidity.
