Samsung Galaxy Note 20 eSIM: compatibility and setup guide

The Samsung Galaxy Note 20 can support eSIM, but the name alone does not confirm that every individual handset can use it. Samsung lists the Galaxy Note20 family among eSIM-compatible Galaxy phones, while noting that availability can depend on the country of origin, the device variant, software and carrier. This guide explains how to check the phone in your hand before choosing a travel plan, then install and use an eSIM if the required options are present.

Look for an EID and Add eSIM in SIM manager. If neither appears after a software update, do not assume another Galaxy Note 20 variant’s compatibility applies to this handset.

Samsung Galaxy Note 20 eSIM compatibility at a glance

Samsung’s Australian guide is designed for Australian variants, and Samsung cautions that eSIM may depend on the country of origin and carrier. The Galaxy Note 20 family has eSIM-capable versions, but verify your handset before buying.

Why two phones with the same name may differ

Galaxy phones are produced in configurations for different markets and carriers. A market-specific or carrier-customized model may not expose the same eSIM controls as an unlocked version elsewhere. Firmware and One UI version can also affect menus, so the box label alone is not enough.

Check the model number in Settings > About phone and look up the specifications for its original market. “Dual SIM” may mean two physical SIM cards or a physical SIM plus eSIM. For an imported or carrier device, confirm its origin, lock status and eSIM availability for that model code.

The absence of 5G from the name in this article is intentional: the supplied device name is Samsung Galaxy Note 20. Do not infer a particular radio configuration or model code from that wording. Confirm those details on the actual phone. eSIM capability is separate from whether a handset supports 4G or 5G, and a travel eSIM's available network technology also depends on the destination network and plan.

Check EID and eSIM settings before you buy

Run both checks below while connected to Wi-Fi. Settings can move between software versions, so use the Settings search field if a menu label differs.

1. Check for an EID. Open Settings > About phone > Status information and look for EID. On some software versions, the status page is reached through About phone > Status. An EID is the identifier associated with the device's embedded SIM hardware. Do not share it publicly; provide it only through a trusted provider's secure support channel if required.
2. Check SIM manager. Go to Settings > Connections > SIM manager. Look for Add eSIM, Add mobile plan or a similar option. If present, open it only far enough to confirm the available setup choices; you do not need to scan a QR code before buying a plan.
3. Update and restart. Install available official software updates, restart the phone, and check again. Make sure the handset is not in a restricted work profile that hides SIM controls.
4. Check the model code and lock status. Under Settings > About phone, note the model number. Confirm that the phone is not carrier-locked and that the eSIM feature is enabled for that market and carrier.
5. Ask the relevant support team if the checks disagree. Samsung or the original carrier can confirm what the model code supports. The provider of the travel plan can confirm whether it accepts that device and what activation method it uses.

An EID is a strong indication that the phone has embedded SIM capability, but it does not prove that every carrier or eSIM plan will activate on it. Conversely, menu visibility and the EID are more useful than an online compatibility list for a phone whose origin is uncertain. Check the compatibility of your device before you choose a plan, and repeat the check if the handset has been reset, updated or changed to another carrier configuration.

Quick compatibility checklist

Before purchasing, make sure that:

• [ ] The phone is the Samsung Galaxy Note 20 variant you intend to use, and you have checked its model code.
• [ ] An EID appears in the phone's status information, or the manufacturer/carrier has confirmed support for that precise variant.
• [ ] SIM manager contains an Add eSIM option.
• [ ] The device is unlocked for use with another provider's eSIM.
• [ ] The phone's software is current and the eSIM plan supports Android devices and the destination.
• [ ] You have stable Wi-Fi for setup and understand when the plan's validity period begins.

If the phone belongs to a company, is managed by an organization, or is subject to a carrier profile, an administrator or carrier may control whether a new SIM can be added. Resolve that restriction before travel. Avoid buying on the assumption that a seller's “dual SIM” description guarantees eSIM.

What to expect from a travel eSIM

A travel eSIM is a digital profile downloaded to compatible hardware. It can provide mobile data abroad while your everyday physical SIM remains installed. A data-only plan usually does not include a regular phone number, voice service or SMS unless the plan says so; internet calling and messaging apps can use data. Coverage and speed depend on the destination, partner networks, the phone’s supported bands and local conditions. Review included countries, data allowance, validity, activation rules and tethering terms before checkout. Some plans start at installation; others start when they first connect to a supported network.

Install and activate an eSIM on Samsung Galaxy Note 20

Use the eSIM provider’s activation details. Connect to Wi-Fi, keep the QR code or manual code available, and do not delete an installed profile unless support advises you to. A QR code may be single-use.

1. Prepare: update the phone, charge it and connect to reliable Wi-Fi. Confirm that Add eSIM appears in SIM manager and that the phone is unlocked.
2. Review the plan: check its destination, setup method and when validity begins. Find the QR code, in-app setup option or manual activation details.
3. Open setup: go to Settings > Connections > SIM manager > Add eSIM. Choose Scan QR code or the offered manual entry option.
4. Download: scan the code shown on another screen or enter the supplied details. Follow the prompts and leave Wi-Fi on until installation completes.
5. Label the profile: name it “Travel data” or another clear label so you can distinguish it from your home SIM.
6. Choose the data line: in SIM manager, select the travel eSIM for mobile data when ready. Keep your home line for calls or messages if needed, but check its roaming charges.
7. Set roaming: enable data roaming for the travel eSIM if its instructions require it. Do not enable roaming for your home SIM without checking its terms.
8. Activate and connect: follow the plan’s timing rules. On arrival, turn on the profile and allow a few minutes to register. If automatic network selection fails, select a supported network manually only as directed by the provider.

For illustrated steps, see the Android eSIM installation instructions and iOS eSIM installation instructions. Samsung Galaxy Note 20 uses Android menus; the iOS page is provided for comparison across devices. If ready to choose a plan, Kaspersky eSIM Store is an app and website where you can select, arrange and activate an eSIM plan for mobile data on a trip abroad. Compare destination, data and validity terms. Kaspersky eSIM Store is not a mobile network operator and does not own the networks used by a plan.

Using the eSIM while travelling

Before departure: Install the profile over dependable Wi-Fi if its terms allow pre-installation. Save the setup instructions for offline access. Decide which line handles data and keep home-SIM roaming off unless you intend to use it and know the cost. Disable large background transfers if you need to conserve data.

On arrival: Turn on the travel eSIM, select it for mobile data and enable its data roaming if required. Keep roaming off on your home line unless planned. Wait for network registration; a partner network name may appear instead of the plan name.

On a multi-country trip: Confirm that each country on your route is included. Regional plans vary, so do not assume a neighbouring country is covered. After crossing a border, allow the phone to register again and check remaining data and validity in the plan interface where available.

For hotspot and everyday use: Check that tethering is permitted before turning on Mobile Hotspot. Monitor consumption under Settings > Connections > Data usage. Maps, messaging and browsing use less data than streaming, app downloads or photo backups; download essentials before travel where practical.

Troubleshooting: eSIM will not install or connect

• No Add eSIM option: check the model code, original market, carrier lock and software version. Update and restart. If the control remains missing, ask Samsung or the original carrier whether that exact variant supports eSIM before purchase.
• QR code rejected or already used: verify that it belongs to this plan, is clearly displayed and has not been scanned before. Some profiles install only once. Ask the plan provider for a replacement instead of repeatedly retrying or deleting a profile.
• Installed but no data: confirm the eSIM is on and selected for mobile data, mobile data is enabled, Airplane mode is off, and roaming is enabled for that line if required. Restart, try automatic network selection, then use a supported network manually if the instructions specify one.
• Signal appears but apps are offline: check plan validity and remaining data, test a webpage and confirm Wi-Fi is not connected without internet. Change the APN only if the provider supplies a value. A data-saving rule, VPN or private DNS can also affect access.
• Home SIM is roaming: reopen SIM manager and verify the data line and roaming setting for each SIM separately. Calls, messages and mobile data can use different defaults.
• Plan looks inactive: re-read whether validity begins at installation or first network connection. Confirm the destination is covered and the correct profile is enabled. Contact the provider if the account status still looks wrong.

If service still fails, restart the phone, toggle Airplane mode briefly and check local coverage. Record the model code, software version, country, displayed network and error message for support. Do not post EID, QR codes or activation details publicly.

Frequently asked questions

Does every Samsung Galaxy Note 20 support eSIM?

No. Samsung includes the Galaxy Note20 family in regional compatibility information, but warns that the country of origin matters. The exact model code, firmware and carrier configuration determine whether a particular phone can add an eSIM. Check the phone itself.

Is an EID enough?

An EID is a useful sign of eSIM hardware, not a guarantee that a particular plan or carrier will accept the phone. Check for Add eSIM too, then confirm plan and destination requirements.

Can I use an eSIM with a physical SIM?

Some configurations allow an eSIM and physical SIM together. You can assign mobile data separately from calls or messages. Review each line’s roaming settings to avoid unwanted charges.

Will a travel eSIM give me a phone number? Can I move it later?

A data-only plan generally does not include a standard number, voice or SMS. Transfer rules vary, so ask the provider before deleting the profile, resetting the phone or moving to another device.

Does eSIM support mean 5G?

No. eSIM is a way to store a SIM profile. Network generation depends on the exact phone, plan, destination network, coverage and settings.

Final device check before choosing a trip eSIM

For Samsung Galaxy Note 20, use the exact phone rather than a product-family assumption: find the model code, look for EID, and confirm Add eSIM in SIM manager. If the controls are missing or the phone was imported or carrier-customized, get confirmation for that specific version before checkout. Then check that the chosen plan covers your destination, suits your data needs and makes clear when its validity begins.

Once those points are clear, you can select an eSIM plan for the trip, install it over Wi-Fi and activate it according to its instructions. A few minutes spent confirming compatibility and settings before departure can make it easier to get mobile data working when you arrive.
