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

The detail and the caveats

First FE model with eSIM.

Samsung pattern: All UK S-series flagships from the S20 (2020) onward have eSIM, but the S20 FE and S21 FE do not (FE models only gained eSIM from the S23 FE). All UK foldables from the Z Flip and Z Fold2 onward have eSIM; the original 2019 Galaxy Fold is unreliable. A-series eSIM arrived with the A54 (patchy) and became dependable from the A55, A35, A56 and A36; other UK A-series models have no eSIM. Two active eSIMs only on S25 and S26 generation flagships, 2025 and 2026 foldables and the Snapdragon S24 Ultra.

Dual eSIM: no, the Galaxy S23 FE 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 Galaxy S23 FE 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 Galaxy S23 FE supported on the ONSIM network? It depends

Whether a phone has eSIM and whether it works on a specific network are different questions. The Samsung Galaxy S23 FE may work on the ONSIM network, but it depends on the software it is running. Check it against the supported devices page before ordering: ONSIM cannot troubleshoot devices outside that list.
