Does the OnePlus Open support eSIM?
Here is what OnePlus's own spec pages say, checked in November 2026.
What OnePlus says by region
- Global, UK and India: the spec pages list "eSIM" under Connectivity (OnePlus Open specs, global, UK, India). The India page adds "Feature availability may vary due to compatibility with local carriers".
- US: the US spec page lists a dual nano-SIM slot and no eSIM line. If you have a US OnePlus Open, check the phone itself (steps below) before you buy an eSIM.
- Other regions: we could not confirm a OnePlus spec page for every region, so we don't state an answer for them.
Is the OnePlus Open dual SIM?
All the spec pages above list a "Dual nano-SIM slot" under Ports. They don't say whether you can use a nano SIM and an eSIM at the same time, so check the SIM settings on your phone to see which lines it offers.

How to check if your OnePlus Open has eSIM
1. Look for the eSIM option in Settings
- Open Settings and tap SIM card & mobile data.
- Look for Manage eSIM Card.
OnePlus's support article says that if Manage eSIM Card doesn't appear there, the phone doesn't support eSIM (OnePlus: How to add an eSIM card). Menu names can differ a little with your OxygenOS version.
2. Check that your phone isn't carrier-locked
If you bought the phone on a contract, your carrier may have locked it to its network. Ask your carrier, or read how to unlock your phone.
How to add an eSIM on the OnePlus Open
OnePlus gives these steps in the support article linked above:
- Connect to Wi-Fi.
- Open Settings > SIM card & mobile data > Manage eSIM Card.
- Tap to download the SIM, then Continue.
- Scan the QR code from your eSIM provider. No QR code? Tap Need help, then Manual input, and enter the activation details.

Using a travel eSIM on your OnePlus Open
A travel eSIM lets you get data abroad without roaming charges, and your home SIM can stay in for calls and texts. It only works if your OnePlus Open shows the eSIM option and is unlocked. Heading to Europe, the USA or Canada? These are data-only plans. Check your phone first, then buy.
