Is the OnePlus OnePlus Open eSIM compatible?

Yes. The OnePlus OnePlus Open (2023) supports eSIM in its UK version.

Verified against the manufacturer and UK carrier sources. Data last updated 2026-07-23.

The detail and the caveats

First OnePlus with eSIM; confirmed on the OnePlus UK spec page.

OnePlus pattern: OnePlus phones had no eSIM until the OnePlus Open (2023) and OnePlus 13 (2025). The 11, 12R and Nord models are physical SIM only in the UK. The OnePlus 12 and 13R have conflicting spec information; verify each handset with *#06# (an EID shown means eSIM capable).

Dual eSIM: no, the OnePlus Open runs one active eSIM at a time (usually alongside the physical SIM).

Verify your exact unit in 10 seconds

Model level answers have limits, especially with grey imports and regional variants. To test the actual OnePlus Open in your hand:

  1. Open the dialler and dial *#06#.
  2. Look for an EID: a 32 digit number shown alongside the IMEI.
  3. EID present = the phone has eSIM hardware. No EID = no eSIM.

You can also check Settings > About phone for an EID entry.

A separate question

Is the OnePlus Open supported on the ONSIM network? No

Whether a phone has eSIM and whether it works on a specific network are different questions. The OnePlus OnePlus Open is not on the ONSIM supported device list, so it will not work on the ONSIM network even if the handset itself supports eSIM. ONSIM is explicit that unlisted devices will not work and it is unable to troubleshoot them. A Virtual Landline (which diverts calls to the phone you already have, on any network) works with every phone.
