No, it only provides a better experience if you change SIM card more often than you change your phone, which isn't the case for most people.
eSIM card transfer can be a hassle, expensive or outright impossible because it's up to the telco to decide it. I had to visit a store in Thailand to transfer my SIM card. I had to pay $ to re-download my eSIM for another operator. I was simply told "can't do" with a still-active eSIM I bought from Airalo.
Definitely nice to "download SIM cards" instead of buying them, but everything that follows is a pain.
And if your phone breaks or something and you need to use your old phone, or borrow a friend's old phone, or whatever, you just move the SIM over.
As a consumer, what benefit does eSIM have?
Better waterproofing?
I'm sure a phone with less external openings like that would still on average fair better against water.
I'm a US/UK resident, and I use an eSIM for my US provider and a physical SIM for my UK provider. Since I use both numbers for various localized services like 2FA, food delivery, etc., the ability to have multiple SIMs has been a huge improvement compared to just a few years ago, when I had to have two phones to be able to log into my bank.
As a consumer, eSIMs are fantastic for international travel. I can have a prepaid international data plan up and running before I even get off the plane.
The only exception is when they've moved to a physically smaller SIM card format.
(This was USA on Verizon)
This is literally never the case unless you buy from your operator in some backwards country like the US.
But I will admit that it's a potential advantage of eSIM. If you do switch somewhat frequently, I can see it being convenient (assuming all the technical stuff works out).
Oh man - My partner pre-ordered an iPhone 14 Pro on launch day, first iPhone with an eSIM. Set up was a nightmare and took over a month to get resolved. She thought she was going to lose her phone number at one point. Still don't know if the fault was with Apple or AT&T but leaning AT&T based on some of the conversations we had between the two teams.
Flash forward a few months and my upgrade and provider change went through without much of a fuss.
Hmm, that seems a bit worrisome for someone like me that doesn't have Play Services and only uses software from F-Droid. I haven't really investigated this.. does it always require an app?
This also enables easier installation and setup for basically any carrier. Just download the app, configure eSIM and you're good. Maybe the easier switching is why adoption is kind-of slow on the carrier side? Easier to keep you locked-in with more obstacles in place.
Seen some comments mention potential issues with it vs physical SIM, but I hope these get resolved with time or standard solutions are developed. Personally I had no issues with it, using it for over 2 years now.
