Is the OnePlus OnePlus 12 eSIM compatible?

It depends. eSIM support on the OnePlus OnePlus 12 (2024) varies by unit or region, so check your exact handset before buying a plan.

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

The detail and the caveats

Sources conflict on the EU model and OnePlus removed eSIM claims from some regional spec sheets; the India model definitely has none; dial *#06# and check for an EID.

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: not applicable, since standard eSIM support is unit dependent on this model.

Verify your exact unit in 10 seconds

Model level answers have limits, especially with grey imports and regional variants. To test the actual OnePlus 12 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 12 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 12 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.

How do I check if my OnePlus OnePlus 12 has eSIM?

Dial *#06# on the OnePlus 12. If an EID (a 32 digit number) appears alongside the IMEI, your unit has eSIM hardware; no EID means no eSIM. You can also open Settings > About phone and look for an EID entry. This checks your exact handset, which matters for grey imports and regional variants.

Can I use two eSIMs at once on the OnePlus OnePlus 12?

Not applicable in the usual sense: eSIM support on the OnePlus 12 is unit dependent, so verify yours first with *#06#.

Does the OnePlus OnePlus 12 work with ONSIM?
