Is the Samsung Galaxy A16 5G eSIM compatible?

No. The Samsung Galaxy A16 5G (2024) does not support eSIM.

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

The detail and the caveats

Nano-SIM only in the UK; not on Samsung's eSIM device list.

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 absent on this model.

Model level answers have limits, especially with grey imports and regional variants. To test the actual Galaxy A16 5G 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.
