Samsung Galaxy Z Fold & TriFold Series

Samsung Galaxy Z Fold phones — the Fold 3, Fold 4, Fold 5, and Fold 6 — all support eSIM alongside the physical nano-SIM. The foldable form factor has no bearing on eSIM support; setup and functionality are identical to the Galaxy S series.

Key Takeaways

• Fold 3: 1 active eSIM alongside physical nano-SIM.
• Fold 4, 5, 6, 7 and Z TriFold: Dual eSIM (two simultaneous active eSIM lines) plus physical nano-SIM.
• Physical nano-SIM slot present on all models — not eSIM-only.
• South Korean Fold 3 and all China/HK/TW variants: NO eSIM.
• Carrier unlock required for third-party eSIMs.

Does Samsung Galaxy Z Fold Support eSIM?

Yes. Every Galaxy Z Fold model released since 2021 supports eSIM. The Z Fold's foldable design is entirely separate from its cellular hardware — the eSIM chip sits on the main board inside the hinge body, unaffected by the flexible display mechanism.

Unlike some US iPhones, Galaxy Z Fold phones retain a physical nano-SIM tray. This means you can keep your home carrier's physical SIM while adding a Roamix travel eSIM as a second line.

All variants listed are for unlocked models. Carrier-locked Z Fold phones require carrier approval to use third-party eSIMs.

How to Activate eSIM on Galaxy Z Fold

1. Open Settings.
2. Tap Connections, then SIM Manager.
3. Tap Add eSIM.
4. Select Scan QR Code.
5. Use the outer or inner camera to scan the Roamix QR code. Roamix emails it within 60 seconds of purchase.
6. Follow the on-screen prompts to complete installation.
7. In SIM Manager, set the Roamix eSIM as your preferred data SIM.
8. Enable Data Roaming for the Roamix SIM.

Using Two Lines on Galaxy Z Fold

Fold 4 and later support Dual eSIM — two eSIM lines active simultaneously alongside the physical nano-SIM. You can run three active lines: home carrier physical SIM, a work eSIM, and a travel eSIM.

Fold 3 supports one active eSIM alongside the physical nano-SIM — two lines at once.

A standard travel setup on Fold 4+:

• Physical nano-SIM (home carrier): Calls and texts. Data Roaming off.
• Roamix eSIM: Preferred data SIM. Data Roaming on.
• Second eSIM (optional): Work or local SIM.

Switch active data SIM at Settings → Connections → SIM Manager → Preferred SIM for mobile data.

Galaxy Z Fold for Business Travel

The Galaxy Z Fold is Samsung's flagship productivity device. Its large inner foldable screen is designed for multitasking — running split-screen apps, annotating documents, and managing multiple windows. For business travelers, an eSIM for local data avoids expensive international roaming while keeping the nano-SIM slot available for a local or corporate SIM.

Z Fold's DeX mode extends the experience to a desktop monitor when abroad, making it a full work setup without carrying a laptop.

Galaxy Z Fold eSIM for International Travel

Roamix works with any unlocked Galaxy Z Fold. Purchase a plan for your destination, scan the QR code before departure, and the Z Fold connects to local partner networks on arrival.

Carrier lock check: Dial *#06# to get your IMEI and contact your carrier to confirm unlock status, or check Settings → General Management → IMEI information.

Galaxy Z Fold eSIM Troubleshooting

"Add eSIM" missing in SIM Manager: The device may be carrier-locked, or the regional variant sold in your country may not include eSIM. Confirm unlock status with your carrier. Regional variants sold in parts of Asia may not support eSIM.

eSIM installed but no signal abroad: Go to Settings → Connections → SIM Manager, set Roamix as the data SIM, and enable Data Roaming. Toggle Airplane Mode off/on to re-register to the network.

QR code won't scan with outer camera: Try the inner camera while the phone is open. Both cameras can read QR codes during eSIM installation.
