- eSIM technology promised frictionless carrier switching, but providers often still require cumbersome steps.
- Transferring a phone number between devices is more complicated with eSIM, especially if the old phone is broken or stolen.
- The eSIM ecosystem lacks a universal standard for sign-up and transfer processes, making cross-platform moves difficult.
- Carrier restrictions from physical SIMs persist in eSIMs, hindering the technology's potential.
- The ideal future would involve a Wi-Fi-like system where users simply scan for carriers and sign up with a username and password.
