Is the Sony Xperia 1 VIII eSIM compatible?

Yes. The Sony Xperia 1 VIII (2026) supports eSIM in its UK version.

Verified against the manufacturer and UK carrier sources. Data last updated 2026-09-01.

The detail and the caveats

Sony's Help Guide for the XQ-GE54/XQ-GE74 states the model supports eSIM, and the same guide identifies XQ-GE54 as the European variant sold in the UK.

Sony pattern: Every UK-market Xperia 1, 5 and 10 from the 2022 Mark IV generation onward supports eSIM, including the 2026 Xperia 1 VIII. The eSIM-capable versions are the European single SIM variants (model numbers ending -54); Asian dual nano-SIM variants (-62/-72/-74) do not have eSIM.

Dual eSIM: no, the Xperia 1 VIII 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 Xperia 1 VIII 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 Xperia 1 VIII supported on the ONSIM network? No

Whether a phone has eSIM and whether it works on a specific network are different questions. The Sony Xperia 1 VIII 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 Sony Xperia 1 VIII has eSIM?

Dial *#06# on the Xperia 1 VIII. 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 Sony Xperia 1 VIII?
