Is the Google Pixel 3a XL eSIM compatible?

Yes. The Google Pixel 3a XL (2019) 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

Dual SIM standby (physical SIM plus eSIM); Japan and Verizon units lack eSIM.

Google pattern: Every Pixel from the Pixel 3 (2018) onward sold in the UK supports eSIM. Pixel 3 has no dual SIM standby; Pixel 3a to 6a run one eSIM alongside the physical SIM; Pixel 7 and later support two active eSIMs. Pixel 2 eSIM only ever worked on Google Fi in the US.

Dual eSIM: no, the Pixel 3a XL runs one active eSIM at a time (usually alongside the physical SIM).

Model level answers have limits, especially with grey imports and regional variants. To test the actual Pixel 3a XL 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 Pixel 3a XL supported on the ONSIM network? No

Whether a phone has eSIM and whether it works on a specific network are different questions. The Google Pixel 3a XL 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.
