I think the major advantage for consumers is being able to securely ensure their cards never breaks and device restarts make their sim always available, no need for pin. Even if someone steals your phone they can’t disable your SIM card unless you don’t have a pincode.

I’ve had a SIM card constantly fail and require me to put my pin to unlock it multiple times in the same day. If someone wanted to call me they would not be able to because I didn’t know it was off.

eSIM is also great for travel. There's a lot of competition on price and it's easy to check esimdb to find the cheapest carrier that meets your needs for a given trip. Download the eSIM in advance and you're good to go as soon as your plane lands
