Does the One Plus Open support eSIM?
Yes, the One Plus Open supports eSIM on all models sold globally. OnePlus built eSIM functionality into this foldable from launch, giving you digital carrier activation without a physical SIM card.
One Plus Open eSIM compatibility
Every One Plus Open variant—regardless of region—includes eSIM support. You get dual SIM capability: one physical nano-SIM slot plus one eSIM profile active simultaneously. This means you can run your home number on the physical SIM and a travel data plan on the eSIM, or vice versa. The device does not support dual eSIM at the same time; you must use the physical slot for your second line if you want two active numbers.
OnePlus confirmed eSIM support for the Open across North America, Europe, and Asia-Pacific markets. The feature works on both carrier-locked and unlocked models, though your carrier must support eSIM provisioning. If you're researching OnePlus eSIM support across the lineup, note that eSIM availability varies by model—the OnePlus 12R, OnePlus 11R, and OnePlus Nord series have different compatibility, so always verify your specific device.
How to set up an eSIM on the One Plus Open
Setting up an eSIM on the One Plus Open takes about 60 seconds once you have your QR code from your carrier or eSIM provider. The process happens entirely in Settings, and you'll see the new line appear immediately after activation.
Set up an eSIM in Settings
- Open Settings and tap Mobile network (or SIM cards & mobile networks).
- Tap Add eSIM or the + icon to add a new carrier profile.
- Select Scan QR code and point your camera at the QR code provided by your carrier or travel eSIM provider.
- Wait while the One Plus Open downloads and installs the eSIM profile—this usually takes 10–30 seconds.
- Label your new eSIM line (for example, "Travel Data" or "Work") so you can distinguish it from your physical SIM.
- Choose which line to use for mobile data, calls, and SMS in the SIM settings. You can switch data between lines anytime.
If your provider sends an activation code instead of a QR code, tap Enter activation code manually in step 3 and type the SM-DP+ address and activation code exactly as provided. The eSIM will install the same way.
Managing dual SIM on the One Plus Open
After activation, both your physical SIM and eSIM appear in Settings under Mobile network. You control which line handles data, which receives calls, and which sends messages. The One Plus Open lets you assign a default for each function or ask every time you place a call or send a text. This flexibility makes the device ideal for separating personal and business use or keeping a home number active while traveling.
Using a travel eSIM on the One Plus Open
A travel eSIM turns the One Plus Open into a genuinely useful device abroad. Instead of paying roaming fees on your home carrier, you install a local data plan as an eSIM before you leave. You land, turn on the eSIM data line, and you're connected—no SIM-card hunt at the airport, no inflated roaming bills.
Install before you fly
Purchase and install your travel eSIM while you're still at home on Wi-Fi. Most eSIM plans activate only when you arrive in the destination country and connect to a local network, so installing early won't waste your data allowance. Keep your physical SIM in place for calls and two-factor authentication texts from your bank, and set the eSIM as your data line. You'll receive calls and messages on your regular number while browsing, navigating, and sharing photos on affordable local data. Browse browse eSIM plans to compare coverage and data allowances for your destination.
The One Plus Open's large, foldable screen makes it especially practical for travel—maps, translations, and travel apps all benefit from the extra real estate, and an eSIM keeps you connected without the usual roaming hassle.
Tips & troubleshooting
Most eSIM activations on the One Plus Open work smoothly, but a few settings adjustments solve common issues.
Turn on data roaming for the eSIM line
Your eSIM won't connect to mobile data abroad unless you enable data roaming for that specific line. Go to Settings > Mobile network, tap your eSIM, and toggle Roaming on. This is safe—you're only roaming on the prepaid eSIM plan, not your home carrier. Keep roaming off for your physical SIM to avoid unexpected charges.
Keep the home SIM for calls and 2FA
Set your eSIM as the default for mobile data, but leave your physical SIM active for voice calls and SMS. This way, you receive verification codes and calls on your regular number while using the eSIM for internet. You configure these defaults in Settings under Mobile network by tapping each SIM and choosing its role.
Fix an eSIM that won't activate
If the QR code won't scan, check that your camera lens is clean and the code is well-lit. You can also enter the activation details manually—your provider should include the SM-DP+ address and activation code in the email with the QR. If the eSIM installs but won't connect, restart your One Plus Open, confirm the eSIM is set as your data line, and verify data roaming is on. Still stuck? eSIM setup help walks through additional troubleshooting steps, and your eSIM provider's support team can reissue the QR if needed.
If you're unsure whether another device you own works with eSIM technology, you can check another device's eSIM compatibility to confirm before purchasing a plan.
