Xiaomi 15 Series

The Xiaomi 15, 15 Ultra, 15T, and 15T Pro Global variants all support eSIM alongside a physical nano-SIM. The critical caveat: Chinese domestic (CN ROM) variants have no eSIM hardware and the error "eSIM feature not available" is the definitive indicator that you have a CN ROM device.

Key Takeaways

• Global variant: eSIM supported on all Xiaomi 15 and 15T models.
• CN ROM variant: NO eSIM hardware — cannot be fixed by software or ROM flashing.
• HyperOS activation path: Settings → Mobile network → Manage eSIM.
• Carrier unlock required for third-party eSIMs like Roamix.

Does the Xiaomi 15 Series Support eSIM?

Yes, on the Global variant. All four Global models include eSIM hardware.

CN ROM warning: If your Xiaomi 15 was purchased from a Chinese retailer (Tmall, JD.com, Xiaomi China store) or imported from China, it almost certainly has CN ROM — no eSIM hardware. The error message is "eSIM feature not available." Installing a Global ROM will NOT add eSIM capability to CN hardware. You need the Global variant of the device.

To verify: Settings → About phone → Model. Global models typically show MXX (EEA), MXX (IN) for India, or similar non-CN suffixes.

Xiaomi 15 eSIM for International Travel

Carrier unlock check: Settings → About phone → SIM card status. Contact your carrier if locked.

Troubleshooting Xiaomi 15 eSIM

"eSIM feature not available": Your device is CN ROM — no eSIM hardware present. This is definitive. The chip is absent. You need the Global variant of the Xiaomi 15.

"Manage eSIM" not in Mobile network settings: On HyperOS, the correct path is Settings → Mobile network → SIM cards & mobile networks → Manage eSIM. If absent on a confirmed Global model, the device may be carrier-locked.

eSIM installed but no data abroad: Settings → Mobile network → select Roamix → enable Data Roaming → set as default data SIM. Toggle Airplane Mode on/off.

QR code scan fails: Must be on Wi-Fi. Tap "Enter activation code" for manual entry using the SM-DP+ address from your Roamix email.
