...how is that an improvement over physical SIM then ;D

I will never use an ESIM due to this. I have had by ass saved multiple times by being able to use a physical sim card when my device failed to work or i needed to be able to port a number.

My last phone went for a swim, I changed phones just be removing the sim card, and putting it in the replacement phone. Easy 20 second process vs an hour trying to argue with customer service that I am the account holder, and no I can't receive a one time pin, the phone is toast then another 20-30 minutes of waiting for the towers to identify that the ICCID changed and that the new sim is actually allowed to communicate with them. The last time I changed my sim card on t-mobile, I didn't have roaming data for almost 30 days due to desync between the USC towers and Tmobile on if I was actually authorized to use the tower or not.

Then back when I used MVNO's it was even worse. Arguing over device compatibility and identification when you lost access to the device was like pulling teeth. The agents never understood that broken means broken, and despite saying 4 times the devices either don't turn on or has no service, they still insist on trying to send a one time pin, because according to their end the phone is active on the tower somehow.

Then there's benefits like when I put an s20 on total wireless 2 years before the company supported 5g devices due to the ability to use a physical sim. I upgraded to an s20 from an s9 after being told that both total wireless and red both supported 5g phones. Only to argue with both of them after I actually bought the device that they couldn't actually activate/transfer it onto the device. I just took the 4g sim card (which they previously said would not work on the device), and threw it into the s20, and then used that until I eventually swapped to a first party carrier.

I could never use an ESIM, you lose way too much control over your device.

Ah yes, obviously. And the author mentioned going to the store in his article.
