Is the Nothing Phone (4a) Pro eSIM compatible?

It depends. eSIM support on the Nothing Phone (4a) Pro (2026) 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

eSIM vendors and community posts report eSIM on the UK model but Nothing has not published a support article confirming it; dial *#06# and check for an EID before buying a plan.

Nothing pattern: The only Nothing phone with confirmed UK eSIM is the Nothing Phone (3) (2025). The 2026 Phone (4a) and Phone (4b) support eSIM only in Japan-market units; the Phone (4a) Pro is unconfirmed. Phone (1), (2), (2a), (2a) Plus, (3a), (3a) Pro and the CMF line are physical SIM only. Nothing is not releasing a flagship Phone (4) in 2026.

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

Model level answers have limits, especially with grey imports and regional variants. To test the actual Phone (4a) 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 Phone (4a) Pro supported on the ONSIM network? No

Whether a phone has eSIM and whether it works on a specific network are different questions. The Nothing Phone (4a) 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.

Does the Nothing Phone (4a) Pro support eSIM?

How do I check if my Nothing Phone (4a) Pro has eSIM?

Dial *#06# on the Phone (4a) Pro. 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 Nothing Phone (4a) Pro?

Not applicable in the usual sense: eSIM support on the Phone (4a) Pro is unit dependent, so verify yours first with *#06#.

Does the Nothing Phone (4a) Pro work with ONSIM?

No. The Nothing Phone (4a) 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. See the supported devices page for what is covered.
