Details & region notes
China variants do not support eSIM.
Can I use a travel eSIM on the Xiaomi 15?
Yes. As long as your Xiaomi 15 is unlocked (not tied to a carrier), you can install a data-only travel eSIM before you fly and activate it on arrival. Travel eSIMs are primarily data plans — you'll get mobile data (including 4G/5G where available) but standard voice calls/SMS usually don't work. You can still make calls via WhatsApp, FaceTime, Signal, Telegram or similar apps.
You can typically store multiple eSIM profiles on your device (several at a time) and switch between them as you travel.
