Is the Oppo Find X3 Pro eSIM compatible?

No. The Oppo Find X3 Pro (2021) does not support eSIM.

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

The detail and the caveats

Dual nano-SIM only.

Oppo pattern: Oppo eSIM support in the UK starts with the Find X5 Pro (2022) and Find N2 Flip (2023); the Find X8 Pro also has it. Earlier flagships like the Find X3 Pro and most Reno models are physical SIM only. Oppo's global spec sheets list eSIM on the Reno16 series (UK launch July 2026) but hedge on carrier and region support, so treat those as unverified until UK carriers list them.

Dual eSIM: not applicable, since standard eSIM support is absent 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 Find X3 Pro 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 Find X3 Pro supported on the ONSIM network? No

Whether a phone has eSIM and whether it works on a specific network are different questions. The Oppo Find X3 Pro 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.

No. The Oppo Find X3 Pro (2021) does not support eSIM. Dual nano-SIM only.

Not applicable in the usual sense: the Find X3 Pro does not support eSIM at all.
