Samsung Galaxy A23 5G

The Samsung Galaxy A23 5G has eSIM hardware only on the UK market variant. Most Galaxy A23 5G models sold globally — including US, wider Europe, and Asia — do not have eSIM hardware. This is a hardware difference between regional models, not a software restriction.

Key Takeaways

• UK model only: eSIM hardware present.
• All other regional A23 5G variants: NO eSIM hardware.
• Check Settings → Connections → SIM Card Manager for "Add eSIM" to confirm your variant.
• Carrier unlock required for third-party eSIMs.

Does the Galaxy A23 Support eSIM?

Only the UK variant. Samsung released the Galaxy A23 5G with eSIM hardware exclusively for the UK market. If you purchased your A23 5G outside the UK — including in the US, Germany, France, Australia, India, or other markets — it almost certainly does not have eSIM hardware. There is no software fix.

To confirm: go to Settings → Connections → SIM Card Manager. If "Add eSIM" is present, your unit has eSIM. If not, it does not.

Galaxy A23 eSIM for International Travel

If you have the UK model, Roamix works with any unlocked Galaxy A23 5G. Purchase a plan, scan the QR code on Wi-Fi, and connect on arrival.

Carrier unlock check: Settings → General Management → Device Information → IMEI status. UK carrier-branded A23 models may be locked for 30–90 days after purchase.

Troubleshooting Galaxy A23 eSIM

"Add eSIM" missing from SIM Card Manager: Your device is a non-UK regional variant without eSIM hardware. This cannot be resolved by software or firmware update. You need the UK market model.

UK model but still no "Add eSIM": The device may be carrier-locked. Contact your UK carrier (EE, Vodafone, O2, Three) to unlock.

eSIM installed but no signal abroad: SIM Card Manager → set Roamix as mobile data SIM → enable Data Roaming. Toggle Airplane Mode on/off.

QR code scan fails: Confirm device is on Wi-Fi. If scanning fails, tap "Enter activation code" in the Add eSIM flow and enter the SM-DP+ address from your Roamix confirmation email manually.
