Samsung Galaxy Z Flip 3 eSIM compatibility by region

The majority of Galaxy Z Flip 3 units sold in North America, Europe, and Asia include eSIM support. However, some carrier-locked variants and models sold in specific markets may have eSIM disabled or restricted by the network operator. If you purchased your device through a carrier, confirm with them that eSIM is enabled on your account and device.

Models sold in mainland China typically do not support eSIM due to regulatory requirements. If you're unsure about your specific variant, check your device's IMEI against Samsung's official spec sheet or contact your carrier to verify eSIM capability before purchasing a plan.

Dual SIM: eSIM plus physical SIM

The Galaxy Z Flip 3 supports dual SIM functionality by combining one physical nano-SIM with one eSIM. You cannot use two eSIMs simultaneously on this device—it's limited to one eSIM active at a time alongside the physical SIM slot. This setup lets you keep your home number on the physical SIM while adding a travel eSIM for data abroad, or separate work and personal lines on one device.

How to set up an eSIM on the Samsung Galaxy Z Flip 3

Setting up an eSIM on your Galaxy Z Flip 3 takes about a minute once you have your QR code from your eSIM provider. Make sure you're connected to Wi-Fi before you begin, and have your QR code ready—either printed or displayed on another screen.

Samsung Galaxy Z Flip 3 eSIM activation steps

Open Settings on your Galaxy Z Flip 3.
Tap Connections, then select SIM card manager.
Tap Add mobile plan or Add eSIM (wording varies by software version).
Select Scan carrier QR code and point your camera at the QR code provided by your eSIM carrier.
Tap Add when the plan details appear on screen.
Wait 30–60 seconds while the eSIM profile downloads and activates.
Label your eSIM line (e.g., "Travel" or "Work") to distinguish it from your physical SIM.
Choose which SIM to use for mobile data, calls, and messages in the SIM card manager settings.

If your eSIM provider sent activation details via email instead of a QR code, select Enter activation code manually in step 4 and type in the SM-DP+ address and activation code.

Set up an eSIM in Settings

After installation, you'll see both your physical SIM and eSIM listed in the SIM card manager. You can toggle each line on or off, set a default for data, and assign specific contacts to ring through a particular number. The Galaxy Z Flip 3 will display small SIM icons in the status bar showing which line is active for data.

Using a travel eSIM on the Samsung Galaxy Z Flip 3

A travel eSIM is the simplest way to get mobile data abroad without paying international roaming fees. Instead of hunting for a local SIM card shop or facing surprise charges from your home carrier, you install a regional or country-specific eSIM before you leave.

Install before you fly

Purchase and install your travel eSIM while you're still at home and connected to Wi-Fi. The profile sits dormant on your device until you land and turn it on. Once you arrive, go to SIM card manager, enable the travel eSIM, and set it as your data line. Your physical SIM stays in place for calls and text messages to your regular number, and you can still receive two-factor authentication codes without roaming charges if you keep that line in airplane mode except when needed.

You can browse eSIM plans for over 200 countries and regions, compare data packages, and install the QR code in minutes. Many travelers install eSIMs for multiple destinations in advance, then activate each one as they cross borders.

Tips and troubleshooting

Most eSIM activations on the Galaxy Z Flip 3 work smoothly, but a few settings and common issues are worth knowing before you travel.

Turn on data roaming for the eSIM line

Your travel eSIM won't connect to local networks unless data roaming is enabled for that specific line. Go to Settings > Connections > Mobile networks, select your eSIM, and toggle Data roaming on. This is not the same as your home carrier's roaming—you're using a local network through the eSIM, so there are no extra charges. Keep data roaming off for your physical SIM to avoid accidental roaming fees on your primary line.

Keep the home SIM for calls and 2FA

Leave your physical SIM installed and set it to handle voice calls and SMS. That way, you can receive verification codes and calls to your regular number while using the eSIM for all data. If you want to avoid any risk of accidental roaming on the physical SIM, enable airplane mode on the device, then manually turn Wi-Fi and the eSIM back on—this keeps the physical SIM dormant but installed.

Fix an eSIM that won't activate

If the QR code won't scan, check that your camera lens is clean and you have adequate lighting. Try increasing the brightness of the screen displaying the QR code, or print it on paper. If scanning still fails, use the manual entry option and type the activation details carefully—extra spaces or typos will cause errors.

If the eSIM installs but shows "No service," confirm that you've turned on data roaming for that line and that the plan is active (some eSIMs activate only when you arrive in the destination country). Restart your Galaxy Z Flip 3 to refresh the network connection. For persistent issues, you can check another device's eSIM compatibility or reach out to eSIM setup help for troubleshooting specific to your carrier.
