Details & region notes
Global/NA/EU/IN units support eSIM. China variants do not.
Can I use a travel eSIM on the OnePlus Open?
Yes. As long as your OnePlus Open 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.
