Samsung Galaxy Z Flip3 eSIM compatibility guide

If you are preparing a trip, the Samsung Galaxy Z Flip3 can add a digital SIM while keeping your physical SIM in place. Samsung's current support information includes Galaxy Z Flip3 among Galaxy devices with eSIM capability. eSIM service can still depend on the country where the phone was sold, the carrier, regional firmware and software, so treat the setting on your own phone as the final check before purchase.

An eSIM is a digital SIM profile downloaded to the phone. For travel, it can be used for mobile data in a selected country, region or route without removing your everyday nano-SIM. A travel eSIM is normally a prepaid data plan: it may not include a regular telephone number, voice calls or SMS unless the terms of that particular plan say otherwise. Messaging and calls through internet apps can still work when the data connection is active.

Quick answer: does Samsung Galaxy Z Flip3 support eSIM?

Yes, an eligible Samsung Galaxy Z Flip3 supports eSIM. Samsung identifies Galaxy Z Flip3 as an eSIM-capable Galaxy model and describes adding a plan through the SIM manager, QR code or manual activation. “Eligible” matters because a model name alone does not guarantee the same feature in every market or carrier version.

The safest conclusion for your specific phone is: Galaxy Z Flip3 is designed to support eSIM, but confirm the handset. Look for an EID or Add eSIM/Add mobile plan. If neither appears, ask the seller or carrier about the exact model and region before buying.

For the Samsung Galaxy Z Flip3, check all of the following:

Check your exact phone before buying

The check below is more reliable than a listing that only says “Z Flip3.” Menu wording can differ after an update or between languages.

Find the EID

1. Open Settings.
2. Tap About phone.
3. Open Status information or Status, depending on the software version.
4. Look for EID.

Samsung also indicates that the EID may be printed on the original box. Do not share it unnecessarily, and use a secure support channel if a provider requests it. It is different from the IMEI because it identifies the embedded SIM component.

Find the eSIM menu

1. Open Settings.
2. Tap Connections.
3. Tap SIM manager.
4. Look for Add eSIM, Add mobile plan, or a similar eSIM option.

If the menu is present, the phone exposes the path needed to add a profile, although this does not confirm that every provider is supported. If it is absent, restart, update the phone and check the EID again. If both remain absent, verify the regional model before purchase.

Compatibility checklist

Use this checklist before you pay for a travel eSIM:

• [ ] An EID appears in the Samsung Galaxy Z Flip3 settings or on its original box.
• [ ] SIM manager shows Add eSIM or Add mobile plan.
• [ ] The phone is not locked to a carrier that prevents another eSIM profile.
• [ ] You know the phone's country or region of sale.
• [ ] The planned destination is included in the selected eSIM tariff.
• [ ] The data allowance and validity period match the trip.
• [ ] You have Wi‑Fi or another working data connection for installation.
• [ ] You know whether the selected plan starts on installation, activation, or first network use.
• [ ] You have checked the plan's rules for roaming data, hotspot use, refills, refunds and transfer.

Check your device before buying a plan if any item is unclear. This small check can prevent a profile from being purchased for a handset that cannot add it or a tariff from being activated at an inconvenient time.

Regional, carrier and software differences

The Samsung Galaxy Z Flip3 was sold in multiple markets and through different carriers. The eSIM feature can therefore be affected by the sales region, the carrier's provisioning rules, the model's firmware and the status of the handset. A phone imported from another country may have a different SIM menu from a phone bought locally. A carrier-branded version can also expose different activation options from an unlocked version.

These differences do not mean that eSIM is always unavailable. They mean that “Samsung Galaxy Z Flip3” is the starting point, not the end. The strongest evidence is an EID, the SIM Manager option and confirmation that the chosen plan works on that variant.

Be especially careful with used, refurbished and imported phones. Ask for the exact model identifier, country of sale and proof that the device reaches Add eSIM. Check for a carrier lock too; that can stop service even when eSIM hardware is present. Dual-SIM support does not guarantee every physical-SIM/eSIM combination on every firmware.

Choosing a travel eSIM tariff

Once compatibility is confirmed, choose the plan around the trip rather than the phone's brand. In Kaspersky eSIM Store, the app and website help you choose, arrange and activate an eSIM with a tariff for mobile internet during an overseas trip. The available offer, coverage arrangement and conditions belong to the selected plan and its underlying local operator network; Kaspersky eSIM Store is not a mobile operator or network owner.

Start with the destination. A country plan may suit one holiday, while a regional plan may suit several countries if its terms cover every border crossing. Estimate usage: navigation, translation, email and messaging use less data than video calls, backups or streaming.

Before confirmation, check the destination, data volume, validity period, activation conditions, hotspot policy and any fair-use limits. Confirm whether the period begins on installation, activation or first connection. Keep the purchase confirmation and activation details available offline.

After the compatibility check, choose an eSIM tariff for your trip. Select the destination and compare the stated data allowance, period and terms in the app or on the site. A travel eSIM may be an alternative to standard roaming, but the right choice depends on the plan and your usage.

How to install and activate an eSIM

Install the profile over reliable Wi‑Fi, preferably before departure, and keep your everyday SIM available until the travel profile works. Confirm the EID, Add eSIM menu, purchase details and activation start before beginning. Do not scan a QR code repeatedly: some profiles are intended for one installation.

For the phone-specific Android path, see the Android eSIM installation instructions. The iOS eSIM installation instructions are included for users who may prepare a plan on an Apple device; they are not the operating-system path for this Samsung phone.

Add the profile with a QR code

1. Open Settings on the Samsung Galaxy Z Flip3.
2. Tap Connections.
3. Tap SIM manager.
4. Tap Add eSIM or Add mobile plan.
5. Choose the option to add the plan with a QR code.
6. Scan the QR code shown on another screen or printed according to the provider's instructions.
7. Wait while the phone downloads the eSIM profile.
8. Confirm the plan name when the phone displays it.
9. Choose whether the new profile or your existing SIM should be the default for calls and messages.
10. Select the eSIM as the preferred line for mobile data when you are ready to use it.

If the QR code is displayed on the same Samsung Galaxy Z Flip3, use another screen or manual entry if supported. Keep it private. If it will not scan, remove glare, raise brightness and confirm the code belongs to this order.

Add the profile manually

1. Open Settings, then tap Connections.
2. Tap SIM manager.
3. Tap Add eSIM or Add mobile plan.
4. Choose manual activation and enter the information supplied for your order.
5. Confirm the download and wait for the profile to appear.

Labels can vary by software version. If manual entry is missing, use the QR route or ask plan support for the supported method. Do not invent activation details.

Activate the data line

After installation, open SIM manager and label the profile “Travel.” Set it as the mobile-data line. If required by the plan, enable data roaming for the travel eSIM only; keep it disabled on the home SIM to avoid unintended roaming.

Turn off automatic switching, disable home-line data or set the travel eSIM as the only data line. Test with Wi‑Fi off by opening a webpage or sending an internet message. Installation, activation and data start are not always the same event, so follow the tariff's conditions.

Using Samsung Galaxy Z Flip3 eSIM on a trip

Scenario 1: one country

Install over Wi‑Fi before leaving. On arrival, set the travel eSIM as the mobile-data line, enable its data roaming if required, turn off home-line data and test navigation.

Scenario 2: several countries

Check that the tariff includes the whole route. Leave automatic network selection enabled unless instructed otherwise. If the phone does not connect, toggle airplane mode and check the plan's network instructions.

Scenario 3: keeping the home number reachable

You can often keep the physical SIM enabled for calls or messages while using the eSIM for data. Check the home carrier's terms and turn off its data roaming. The travel eSIM is for mobile internet, not automatically your regular number.

Troubleshooting common problems

There is no Add eSIM option

Check Settings → About phone → Status information for an EID, then Settings → Connections → SIM manager. Restart and update the phone. If both are missing, the region, firmware or variant may not expose eSIM; confirm the model before buying.

The QR code will not scan

Use stable Wi‑Fi and display the full code on a second screen. Remove glare, confirm it belongs to this order and has not been used. If manual activation is supported, enter the details exactly; keep the code private.

The profile will not download

Confirm that the phone is online, date and time are automatic, and storage is available. Check SIM manager for a partial profile. Avoid repeated retries; contact plan support with the error and device variant.

The eSIM is installed but there is no data

Confirm in SIM manager that the travel profile is enabled for mobile data. Turn off Wi‑Fi, check eSIM data roaming if required and verify airplane mode is off. Follow only the plan's APN instructions, then restart or toggle airplane mode.

The connection is slow or stops

Check remaining data, validity and destination conditions. Try a better-signal area and restart the connection. Crowding, coverage, a depleted allowance or plan restrictions can affect performance; a travel eSIM does not guarantee a particular speed.

The phone is locked

An operator lock can prevent another eSIM profile even when the phone has an EID. Ask the original carrier about unlocking eligibility before purchasing a plan.

Frequently asked questions

Does every Samsung Galaxy Z Flip3 have eSIM?

No. Samsung lists Galaxy Z Flip3 as supported, but eSIM service can vary by country and carrier. Check the EID, SIM Manager menu and regional variant.

Is an EID proof that the travel tariff will work?

Not by itself. The carrier, region, device lock and plan conditions also determine whether a profile can be downloaded and used.

Will a travel eSIM give me a telephone number?

Not unless the selected tariff expressly includes one. Travel eSIM offers in this context are for mobile internet. Regular calls and SMS are not included by default; internet messaging apps can use the active data line.

What does Kaspersky eSIM Store do?

Kaspersky eSIM Store is an app and website where you can choose, arrange and activate an eSIM with a tariff for mobile internet during an overseas trip. It is neither the operator, network owner nor mobile-network provider; the plan's conditions determine destination, data, validity and restrictions.

Final device check before your trip

Complete this sequence before purchasing or packing:

1. Confirm the EID and Settings → Connections → SIM manager → Add eSIM.
2. Confirm that it is not carrier-locked and verify the region if imported or refurbished.
3. Choose a tariff covering every destination; compare data, validity, activation start and hotspot conditions.
4. Install over Wi‑Fi, set it as the data line and enable eSIM roaming only when required.
5. Test mobile data with Wi‑Fi off and keep support details accessible.

Choose an eSIM for the journey

Samsung lists the Galaxy Z Flip3 as eSIM-capable, but the handset still needs the EID, SIM Manager, region and carrier checks. Once they pass, use Kaspersky eSIM Store to choose, arrange and activate a suitable eSIM tariff for mobile internet abroad. Match data and validity to the itinerary, then review activation conditions.
