UUPAY eSIM Compatibility & Migration Limitations
While eSIM technology offers significant convenience, users should be aware of the following technical considerations:
Hardware Compatibility: eSIM technology is not yet universally available across all mobile devices. Some legacy models or budget-tier smartphones may not support eSIM functionality.
Complex Migration Process: Unlike the "plug-and-play" nature of physical SIM cards, moving an eSIM profile between devices is more complex. It cannot be achieved through a simple physical swap; instead, it typically requires a re-installation or a manual transfer process initiated through the carrier's system.
