Samsung Galaxy S20 eSIM: compatibility and setup guide

The Samsung Galaxy S20 can support eSIM, but the name on the box is not enough to confirm that a particular phone will accept a travel eSIM. Samsung lists the S20 family among its eSIM-capable Galaxy devices and also cautions that support may depend on the country where the device was sold. The exact model number, software, and carrier configuration matter. Before choosing a plan, check the phone itself for an EID and an option to add an eSIM.

Does the Samsung Galaxy S20 support eSIM?

The Samsung Galaxy S20 family supports eSIM on eligible versions. Samsung’s support information includes Galaxy S20 and S20 5G, and its S20 SIM guidance marks eSIM as supported. However, Samsung also says that eSIM may not be available on a listed device depending on its country of origin. A carrier-branded version can have a different software configuration from an unlocked or another-market version, and support can also depend on the installed firmware.

For that reason, treat the answer for an unspecified Samsung Galaxy S20 as potentially compatible, subject to a device-level check. Do not assume that every S20 sold in every country has eSIM enabled. The reliable confirmation is the presence of an EID and an eSIM installation control in the settings of your own phone. If neither is present, ask Samsung or the seller to confirm support for the full model code and sales region before buying a plan.

The base Samsung Galaxy S20 is distinct from the S20+, S20 Ultra, and S20 FE. This guide covers only Samsung Galaxy S20; check each other model against its own model code and settings.

Compatibility at a glance

An EID identifies the eSIM component and differs from the phone’s IMEI. Its presence is a useful compatibility signal; “Add eSIM” confirms that the current software exposes the setup flow. Check both where possible.

Check the exact phone before buying a plan

Do these checks on the Samsung Galaxy S20 you intend to take on the trip. Menus can vary slightly by Android version, One UI release, language, and carrier customization, so labels may read “SIM manager,” “SIM card manager,” or similar.

1. Find the model code. Open Settings → About phone and note the full model number. Do not rely only on the product name shown on the box or in an online listing. The model code helps Samsung or the seller identify the sales market and carrier version.
2. Look for an EID. Open Settings → About phone → Status or Status information. On supported software, the EID appears with other device identifiers. Samsung also notes that the EID may be printed on the original phone box. Keep the number private and share it only when a provider needs it for setup.
3. Open the SIM controls. Go to Settings → Connections → SIM manager. Look for Add eSIM, Add mobile plan, or a comparable option. If the phone has a physical SIM installed, the menu may also show its current profile.
4. Check for software updates. If the model is known to support eSIM but the option is missing, install available official system updates, restart the phone, and check the SIM manager again. A missing menu can reflect the region or firmware rather than a setting you can switch on yourself.
5. Confirm that the phone is unlocked. A carrier lock may prevent a profile from connecting to another network even when the phone has eSIM hardware. Ask the carrier that sold or activated the phone to confirm its unlock status.
6. Ask about the exact SKU if anything is unclear. Give Samsung support or the seller the full model code, country of sale, and software version. Ask specifically whether that configuration supports downloading a third-party eSIM profile for travel.

If the EID and eSIM option are both missing, verify the model before purchase. If only the menu is missing, check for updates and ask Samsung about the regional firmware. An EID alone does not guarantee plan eligibility or remove a carrier lock.

Check your device before selecting a plan, especially if the Samsung Galaxy S20 was bought second-hand, imported, or supplied by a carrier in another country.

Regional and carrier versions: what can differ

“Samsung Galaxy S20” is a product name, not a complete hardware identifier. Samsung sold different model codes and network configurations by country and carrier. LTE or 5G branding alone does not confirm eSIM support; a version may lack the feature in its regional firmware.

Check three separate things:

• Does this handset have eSIM capability? Check the model code, EID, SIM manager, and firmware.
• Can this eSIM profile be installed? The profile’s provider and activation method must be compatible with the device’s available setup flow.
• Can it connect in the destination? The plan must cover the country or region, and the phone must be unlocked and able to use a supported local network.

A domestic operator’s eSIM support is separate from support for a travel data plan. Samsung warns that eSIM availability varies by country and carrier. Check the rules for the exact operator market and the phone’s sales region.

A physical SIM tray does not prove or disprove eSIM support. On eligible versions, a nano-SIM and eSIM can coexist, but Samsung says only two SIMs can be active at once. If you currently use two physical SIMs, choose which lines to enable before travel.

Install and activate an eSIM on Samsung Galaxy S20

Connect to Wi-Fi or another working data connection. Keep the QR code on a separate screen or printout; the phone cannot scan its own display. Check the plan’s activation timing and whether its code can be reused.

QR-code installation

1. Check compatibility first. Confirm that the phone shows an EID and an eSIM option, and that it is not carrier-locked.
2. Open SIM manager. On the phone, go to Settings → Connections → SIM manager (the wording can vary slightly).
3. Choose the add option. Tap Add eSIM or Add mobile plan.
4. Scan the code. Choose the QR option and scan the plan code. If it fails, use manual details only when supplied by the provider.
5. Download the profile. Keep the phone online and follow the plan’s activation instructions; download and start of service may be separate events.
6. Name the profile. Use a label such as “Travel data” to distinguish it from your home SIM.
7. Set the data line. Select the travel eSIM for mobile data; keep calls and messages on your usual line if desired.
8. Check roaming. Enable it on the travel eSIM only if its instructions require it.

Manual or assigned-plan installation

For an activation code, open Settings → Connections → SIM manager → Add eSIM/Add mobile plan, choose manual activation, and enter the supplied details exactly. Do not guess fields or reuse a code. If a provider assigns a plan to the device, follow its steps and share the EID only through its intended process.

See the Android eSIM installation guide for Android setup. The iOS guide applies to iPhone, not Samsung Galaxy S20.

A profile can appear ready before network connection. Activation timing varies; do not delete it unless the provider confirms it can be reinstalled.

Use the Samsung Galaxy S20 for mobile data while travelling

A common setup is to keep your regular physical SIM available for calls or messages and select the travel eSIM for mobile data. The exact combination depends on the phone version and current SIM setup; Samsung says only two SIMs can be active at once. Before departure, install over Wi-Fi if the plan permits it and check when its validity begins. Some plans start on installation, others on activation or first connection.

After arrival, open Settings → Connections → SIM manager, switch on the travel profile, and select it for mobile data. Enable data roaming on that profile only if the plan instructions require it. Keep roaming off for your home SIM if you do not intend to use its service. Turn off Wi-Fi to test a webpage or map, and allow a few minutes for network registration. For a multi-country trip, confirm every destination is included.

The travel eSIM use case here is mobile data; a standard phone number, voice calls, or SMS are not included unless the plan says otherwise. Data-based apps can work over the connection. Kaspersky eSIM Store is an app and website where you can choose, arrange, and activate an eSIM with a mobile-data plan for an overseas trip. Check destination, data allowance, validity, and activation terms; coverage depends on local networks and conditions.

Troubleshooting common eSIM problems

“Add eSIM” is missing

Check Settings → About phone → Status for an EID, note the model code, install available official updates, and restart. If the menu remains absent, ask Samsung or the seller whether that sales region and carrier version support eSIM.

The QR code will not scan or the profile will not download

Open the QR flow through SIM manager and display the code on another device. If scanning still fails, use manual activation only when the provider supplied details. Confirm the code is valid and unused; do not repeatedly retry if downloads are limited.

The profile is installed, but there is no data

Switch on the eSIM and select it for mobile data. Check that the plan is active for your date and destination, then enable data roaming on that profile if instructed. Turn off Wi-Fi, toggle airplane mode briefly, and allow the phone to register. If needed, follow the provider’s local network guidance.

Apps cannot connect or the wrong line is using data

Confirm the preferred data SIM and check the allowance or validity. Enter APN settings only when the provider supplied them. Review the home SIM’s separate data and roaming switches if you do not want it to use roaming.

The phone is locked or activation is rejected

An eSIM menu does not remove a carrier lock. Ask the original carrier to confirm unlock status. If unlocked, give the plan provider the model code and error message to check profile and destination compatibility.

Can I delete and reinstall the eSIM?

Ask the provider first. Some profiles or QR codes cannot be reused after removal, and deleting the phone profile may not cancel a separate plan arrangement.

Practical travel scenarios

• City break: install the profile over Wi-Fi if allowed, then select it for maps, bookings, and messaging after arrival.
• Work trip: keep the home SIM available for its number and use the travel eSIM for data; review the home carrier’s roaming terms.
• Several countries: check that every stop is covered and recheck the data line at each border.
• Two active SIMs already: choose which two lines to keep on, since an eSIM cannot be active alongside two physical SIMs.

Frequently asked questions

Is every Samsung Galaxy S20 eSIM-compatible?

No. Samsung lists the model family but warns that availability can depend on country of origin. Check the exact phone’s EID and SIM manager.

Where can I find the EID?

Look under Settings → About phone → Status or Status information. It may also be printed on the original box.

Can a physical SIM and eSIM work at the same time?

Yes, on eligible versions. Samsung says only two SIMs can be active together, so two physical SIMs plus eSIM cannot all be enabled at once.

Will a travel eSIM give me a phone number?

Not by default. Check the plan terms; this travel data use case is for mobile internet, while messaging apps can use the data connection.

Should I enable data roaming?

Only when the selected eSIM plan requires it. Check the roaming setting for the travel profile, not just the home SIM.

Can I install it before flying?

Often, if the plan permits it and you have Wi-Fi. Confirm whether validity begins at download, activation, or first connection.

Final check before your trip

The Samsung Galaxy S20 supports eSIM on eligible versions, but the model name alone cannot confirm your handset. Check its EID and Add eSIM option, note the full model code, update the software, and confirm that it is unlocked. If the controls are missing or the phone was imported, verify its regional configuration before choosing a plan.

Match the plan to your destination, dates, data needs, and activation timing. Kaspersky eSIM Store helps you choose, arrange, and activate an eSIM with a mobile-data plan for an overseas trip. Confirm compatibility and the plan terms before setting the eSIM as your data line.
