Why won't eSIM install in Vietnam if my phone supports eSIM?
Based on 1 discussions with 3 participants · Last activity: 2 days ago
TL;DR
If you get a device incompatibility error when installing an eSIM in Vietnam, your phone likely doesn't actually support eSIM — Chinese market versions of phones often have dual physical SIM slots instead of eSIM support.
What the community said
A device incompatibility error when installing an eSIM almost always means the phone genuinely doesn't support eSIM, even if you think it does. Chinese market versions of iPhones and Android phones are commonly released with two physical SIM slots instead of eSIM capability. Check your exact model number online to confirm.

If your device doesn't support eSIM, installation simply won't work. Look up your specific phone model online to verify eSIM compatibility — support varies by regional variant and firmware version.
