Do Chinese ROM Phones Support eSIM? China vs Global Phone-by-Phone

Do Chinese ROM phones support eSIM? On the flagships we checked, no. The Chinese versions of the OnePlus 15, Oppo Find X9 Pro, vivo X300 and Xiaomi 17 Ultra do not support eSIM, while the global versions of the first two do.

If you rely on an eSIM for travel, a second number or a carrier that only sells eSIM plans, this single feature can decide which version of a phone you should buy.

All Chinese ROM Phones Support eSIM in this list

eSIM Support by Phone: China vs Global

Phone	Chinese version	Global version	Source
OnePlus 15	No eSIM	Dual nano-SIM plus two eSIM profiles	Gizmochina
Oppo Find X9 Pro	No eSIM	eSIM supported	Notebookcheck
Xiaomi 17 Ultra	No eSIM	Not covered in our sources	Notebookcheck
Vivo X300 (and Pro)	eSIMs cannot be used	Not covered in our sources	Notebookcheck

We only list what a source states. For the global Xiaomi 17 Ultra and vivo X300, our sources say that the Chinese version lacks eSIM, but they do not spell out the global version’s support, so check the official spec sheet for your region before you buy.

Why Chinese Phones Often Lack eSIM

We did not find an official statement of the reason. The pattern is clear in the reviews, though: Chinese-market models use two physical nano-SIM slots, while the international versions add eSIM on top. If a phone matters to you for its eSIM, buy it through a regular store in your own region, and not as a Chinese import.

Who Needs eSIM?

Frequent travelers who buy local data plans on arrival.
Dual-number users who keep a work and a personal line without carrying two SIM cards.
People whose carrier sells eSIM-only plans. Check this with your carrier before you import.
Anyone who changes phones often, because moving an eSIM is faster than swapping cards.

What to Do If You Still Want the Chinese Version

Use two physical SIMs. Chinese flagships normally have two nano-SIM slots, which is enough for two numbers if your carrier gives you a SIM card.
Ask your carrier for a physical SIM for the second line instead of an eSIM.
For travel, buy a local physical SIM or use a travel router instead of a travel eSIM.

Other Limits That Come With the Missing eSIM

The missing eSIM is usually not the only difference. According to Notebookcheck, the Chinese Xiaomi 17 Ultra also lacks Android Auto and Wear OS compatibility, and Wear OS pairing is difficult on the Chinese Find X9 Pro and on the vivo X300.

How to Check eSIM Support Before You Buy

Find the exact model number of the version you are buying (see our model number guide).
Open the official spec sheet for that region and look for “eSIM” under the SIM section.
Read an import review such as the Notebookcheck verdicts listed above, because they state what is missing.
Ask the seller to confirm in writing that the phone supports the SIM setup you need.

What to Ask Your Carrier Before You Buy

The best way to avoid eSIM surprises is to ask your carrier three questions before you import a phone:

Do you sell physical SIM cards for new and existing plans, or only eSIM?
Can I get a second number on a physical SIM?
Does your roaming or travel plan require eSIM?

If the answers are all “yes, physical SIM is fine”, a Chinese phone with two nano-SIM slots works well. If your carrier is eSIM-only, or you travel and rely on travel eSIMs, buy the global version. Also check our guide on network bands, because a phone that connects but has poor coverage is just as frustrating as one without eSIM.
