Is the Samsung Galaxy Fold eSIM compatible?

It depends. eSIM support on the Samsung Galaxy Fold (2019) 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 present in hardware but shipped disabled on several regional firmwares; UK units vary, check for an EID with *#06#.

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: not applicable, since standard eSIM support is unit dependent 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 Galaxy Fold 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 Fold supported on the ONSIM network? No

Whether a phone has eSIM and whether it works on a specific network are different questions. The Samsung Galaxy Fold 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 Samsung Galaxy Fold has eSIM?

Dial *#06# on the Galaxy Fold. 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 Samsung Galaxy Fold?

Not applicable in the usual sense: eSIM support on the Galaxy Fold is unit dependent, so verify yours first with *#06#.
