The FE label changes the answer
The Galaxy S21 FE 5G does not support eSIM in our sourced record. The S21, S21+ and S21 Ultra have eSIM-capable versions, subject to market, software and carrier support.
For a second-hand S21, a carrier unlock and eSIM availability are separate questions. Ask for its full SM-model number and look for Add eSIM in SIM manager before buying a travel plan.
Check the actual S21 in your hand
Open Settings → About phone and note the model number. Then open Settings → Connections → SIM manager and look for Add eSIM. Older software can call these SIM card manager and Add mobile plan.
If the option is missing on a model that should support it, check for an official software update and ask Samsung or the original carrier about that exact version. Do not assume a firmware change or an eSIM app can convert an unsupported variant.
An EID or eSIM menu is useful device evidence, but it does not establish carrier-unlock status. Ask the original carrier before using a plan from another provider.
Questions about Galaxy S21
Do Samsung Galaxy S21+ and S21 Ultra support eSIM?
They have eSIM-capable versions. The full model number, original market, software and carrier requirements still need checking. A family name alone cannot establish support on an imported phone.
Does Samsung Galaxy S21 FE 5G support eSIM?
No. Galaxy S21 FE 5G is a physical-SIM model in the manufacturer evidence cited here. Unlocking it or installing an app does not add eSIM hardware.
The model records on this page retain their own regional and hardware evidence. Compatibility is documented from manufacturer sources. This does not represent hands-on activation testing.
EXACT MODEL EVIDENCE
Check the version you own
Compare the full model and A-number or SM-number where listed. The phone’s original market can differ from the shop where you bought it or the country you are visiting.

Open Settings → About phone for the full model number, then Connections → SIM manager for Add eSIM. Older software may say SIM card manager and Add mobile plan. If neither option is available, ask Samsung or the selling carrier about that exact model and software. Ask the original carrier separately about unlocking.
An EID indicates eSIM hardware. It does not prove the phone is unlocked, that every provider will accept it or that a plan includes coverage at your destination. Do not send us your IMEI, EID or account details.
