OnePlus eSIM Guide

OnePlus flagship phones have supported eSIM since the 9 Pro in 2021. The OnePlus 9 Pro, 10 Pro, 11, 12, and 13 all include eSIM in US and European variants. eSIM support in the OnePlus lineup is heavily variant-dependent — the same model sold in Asia or Latin America may not include eSIM hardware.

Key Takeaways

• OnePlus 9 Pro through 13 support eSIM in the US and Europe.
• eSIM availability varies significantly by regional variant.
• Physical nano-SIM slot present — not eSIM-only.
• One active eSIM at a time alongside physical SIM.
• Carrier unlock required for third-party eSIMs like Roamix.

Does OnePlus Support eSIM?

Yes — for flagship models in major markets. OnePlus introduced eSIM with the 9 Pro (2021) and has included it in US/European variants of every flagship since. The clearest way to confirm your specific device supports eSIM is to check Settings → Network & internet → SIM cards — if an "Add eSIM" or "Download eSIM" option appears, your device supports it.

India variant warning: OnePlus phones sold through Amazon.in and Flipkart are often the India-specific variant without eSIM hardware, even on flagship models. If you purchased your OnePlus in India, confirm the model number at Settings → About device → Model before purchasing an eSIM.

CN variant warning: Chinese domestic OnePlus variants have no eSIM hardware.

OnePlus Models and eSIM Compatibility

eSIM availability varies by regional variant. US and European models of the listed phones support eSIM. Other regional variants may not.

How to Activate eSIM on OnePlus

1. Open Settings.
2. Tap Network & internet, then SIM cards (or SIM & network).
3. Tap Add eSIM or Download eSIM.
4. Select Scan QR code and point your camera at the Roamix QR code.
5. Follow the on-screen prompts to install.
6. Set the Roamix eSIM as your preferred data SIM.
7. Enable Data Roaming for the Roamix SIM.

The exact menu path may vary slightly between OxygenOS versions.

Using Two Lines on OnePlus

OnePlus phones support one active eSIM alongside the physical nano-SIM. For international travel:

• Physical SIM (home carrier): Calls and texts. Data Roaming off.
• Roamix eSIM: Primary data line. Data Roaming on.

Manage SIM settings at Settings → Network & internet → SIM cards.

OnePlus eSIM for International Travel

Roamix works with any unlocked OnePlus that includes eSIM on its variant. Purchase a plan, scan the QR code, and your phone connects to local partner networks when you arrive.

Carrier lock check: Settings → About device → SIM status. OnePlus phones sold unlocked in the US (through OnePlus.com or Amazon) typically have no carrier restrictions.

OnePlus eSIM Troubleshooting

No "Add eSIM" option in settings: Your specific OnePlus variant may not support eSIM. India variants (Amazon.in/Flipkart purchases) and CN variants frequently lack eSIM hardware. Check Settings → About device → Model to identify your variant. If confirmed as a non-US/non-European model, eSIM may not be available at all.

eSIM installed but no service abroad: Set Roamix as data SIM and enable Data Roaming. Toggle Airplane Mode off/on to reset network registration.

OxygenOS version differences: The menu path for eSIM may differ between OxygenOS 13 and 14. If "Add eSIM" is not visible under SIM cards, check under Settings → Mobile network or Settings → Connections.

QR code scan fails or eSIM download rejected: Ensure you are on Wi-Fi during the activation — mobile data alone is not sufficient. If scanning fails repeatedly, use the "Enter activation code" option and enter the SM-DP+ server address and activation code from your Roamix confirmation email. Ensure your OnePlus is fully carrier-unlocked before retrying.
