Samsung Galaxy Z Flip Series

Samsung Galaxy Z Flip phones — the Flip 3, Flip 4, Flip 5, and Flip 6 — all support eSIM alongside the physical nano-SIM. The clamshell form factor folds the phone in half for a compact carry, but the eSIM hardware and setup are no different from a standard Samsung Galaxy phone.

Key Takeaways

• Flip 3: 1 active eSIM alongside physical nano-SIM.
• Flip 4, 5, 6, 7 and Flip 7 FE: Dual eSIM (two simultaneous active eSIM lines) plus physical nano-SIM.
• Physical nano-SIM slot present on all models — not eSIM-only.
• Must be fully open to scan QR code during eSIM setup.
• South Korean Flip 3 and all China/HK/TW variants: NO eSIM.

Does Samsung Galaxy Z Flip Support eSIM?

Yes. The Galaxy Z Flip lineup has included eSIM since the Flip 3 (2021). The clamshell hinge and flexible display are purely mechanical features — they have no effect on the eSIM chip, which is embedded in the phone's main circuit board.

All Z Flip models retain a physical nano-SIM tray, unlike US iPhones from iPhone 14 onward. This means travelers can keep a home carrier SIM in the tray while using a Roamix data eSIM for international travel.

Galaxy Z Flip eSIM Compatibility by Generation

Carrier-locked Z Flip phones (e.g., purchased on carrier installment plans) may require carrier unlock before using third-party eSIMs.

How to Activate eSIM on Galaxy Z Flip

1. Open the phone — the Z Flip must be fully unfolded to access Settings.
2. Go to Settings.
3. Tap Connections, then SIM Manager.
4. Tap Add eSIM.
5. Select Scan QR Code.
6. Point the rear camera at the Roamix QR code. Roamix emails it within 60 seconds of purchase.
7. Follow the on-screen prompts to complete installation.
8. In SIM Manager, set the Roamix eSIM as your preferred data SIM.
9. Enable Data Roaming for the Roamix SIM.

Using Two Lines on Galaxy Z Flip

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

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

A standard travel setup on Flip 4+:

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

Manage SIMs at Settings → Connections → SIM Manager → Preferred SIM for mobile data.

Galaxy Z Flip and the Cover Screen

Galaxy Z Flip 5 and Flip 6 introduced a large cover Flex Window that lets you interact with the phone while it's closed. From a travel eSIM perspective, the cover screen can:

• Show data connection status and signal strength.
• Display incoming call alerts on whichever SIM receives them.
• Surface notifications from your eSIM provider.

This is useful on the go — you can confirm the Roamix eSIM is active without opening the phone.

Galaxy Z Flip eSIM for International Travel

Roamix works with any unlocked Galaxy Z Flip. Purchase a plan, scan the QR code on Wi-Fi before you travel, and the Flip connects automatically to local networks when you land.

Carrier lock check: Contact your carrier or go to Settings → General Management → IMEI information. Phones purchased directly from Samsung (samsung.com) are sold unlocked and work with all third-party eSIMs.

Galaxy Z Flip eSIM Troubleshooting

"Add eSIM" missing from SIM Manager: Your device may be carrier-locked. Confirm with your carrier that the phone is fully unlocked, then retry. Regional variants sold in parts of Southeast Asia or Latin America may also lack eSIM hardware on the same model number.

QR code won't scan while phone is partially folded: The Z Flip camera requires the phone to be fully open (flat) for QR code scanning during eSIM installation. Ensure the phone is completely unfolded before scanning.

eSIM active but no data abroad: Go to SIM Manager, confirm Roamix is set as the data SIM, and enable Data Roaming for that SIM. Toggle Airplane Mode off/on to refresh network registration.
