No. The Xiaomi Xiaomi 12T (2022) 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; only the 12T Pro got eSIM.

Xiaomi pattern: Xiaomi flagships have eSIM on global/UK ROMs from the 12T Pro (2022) onward, with the notable exception of the 14 Ultra, which has no eSIM anywhere. Devices on Chinese ROMs never support eSIM. Most Redmi and POCO phones have no eSIM; exceptions are the Redmi Note 13 Pro+ 5G and Note 14 Pro / Pro+ 5G global models.

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 Xiaomi 12T 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 Xiaomi 12T supported on the ONSIM network? No

Whether a phone has eSIM and whether it works on a specific network are different questions. The Xiaomi Xiaomi 12T 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.
