Samsung Galaxy S20+ 8GB RAM eSIM: compatibility and travel setup

If you are preparing a trip and want mobile data without changing the physical SIM card, check whether your exact Samsung Galaxy S20+ 8GB RAM variant exposes an eSIM. Samsung supports eSIM on relevant versions, but country, model code, carrier customisation and software can change the SIM settings.

Samsung’s current support information lists the Galaxy S20+ among Galaxy devices that can support eSIM. Samsung’s product information also explains that eSIM availability may vary by country and carrier. The 8GB RAM configuration is normally associated with the LTE version, while the Galaxy S20+ 5G configuration was commonly sold with 12GB RAM. These are related products, not interchangeable names. For this page, the target remains exactly Samsung Galaxy S20+ 8GB RAM.

That distinction matters before you select a travel plan. RAM capacity does not activate eSIM by itself. The reliable test is on the phone: look for an EID in the device status information and for an option such as Add eSIM, Add mobile plan or Add using QR code in the SIM manager. If those controls are missing, do not assume that a QR code will work. Confirm the model code and ask the carrier or seller about that specific regional version first.

Quick answer: does Samsung Galaxy S20+ 8GB RAM support eSIM?

Samsung documents eSIM support for the Galaxy S20+ family and describes adding a plan through the SIM manager. For Samsung Galaxy S20+ 8GB RAM, the practical answer is compatible when the regional and carrier variant exposes eSIM; imported, refurbished and operator-branded phones still require their own check.

Use this decision rule:

1. If About phone → Status shows an EID, the phone has an eSIM identity.
2. If Connections → SIM card manager contains Add eSIM or Add mobile plan, the software can start setup.
3. If both checks succeed, a compatible travel eSIM can usually be installed, subject to plan requirements.
4. If neither is present, stop before buying. A physical dual-SIM tray does not prove eSIM is enabled.

Two phones with the same retail name can differ because of market firmware or carrier provisioning. The on-device menus and EID are therefore more useful than a generic specification list.

Main characteristics to check

Why the exact regional version matters

The Galaxy S20 line was released in several LTE/5G, memory, storage, SIM and market-software combinations. “Samsung Galaxy S20+” alone is too broad for a purchase decision. “8GB RAM” helps identify the intended LTE configuration, but not the full model code or carrier policy.

Check Settings → About phone for the model name and model number, including a dual-SIM suffix. Do not infer compatibility from the processor, the physical SIM tray, 4G or 5G, or RAM. A friend’s Galaxy S20+ is useful for comparison only when its model code, market and software also match.

An imported or carrier-branded phone can behave differently from a local version. Firmware may hide the add-plan control, and the carrier or plan may require an unlocked device or supported band. An EID confirms the embedded SIM identity, not that every plan can be provisioned.

Compatibility check before purchase

<a id="kesim-device-compatibility"></a>

Complete these checks while you still have Wi-Fi and before you pay for a travel eSIM:

• Confirm the phone name and model number under Settings → About phone.
• Confirm that the software is current enough for the menus supplied with your regional model.
• Open Settings → Connections → SIM card manager and look for Add eSIM, Add mobile plan, or a similar option.
• Open About phone → Status and look for EID. On some versions it may appear under SIM status or be available by tapping status information.
• Check that the phone is not locked to a carrier that prevents another eSIM plan from being added.
• Check that the travel plan supports Android and the destination you will visit.
• Make sure you have Wi-Fi or working mobile data for the download.
• Keep the physical SIM active if you need its number for calls or one-time codes, but decide which line will be used for mobile data.

For a compact pre-purchase walkthrough, check your device using the same EID and SIM-manager tests.

A simple compatibility checklist

Device identity

• [ ] The model number has been copied from the phone, not from a listing headline.
• [ ] The name still matches Samsung Galaxy S20+ 8GB RAM.
• [ ] The device is not confused with the 5G or another RAM variant.

eSIM capability

• [ ] An EID is visible, or Samsung’s support path identifies an eSIM for the exact version.
• [ ] SIM card manager shows an add-plan or add-eSIM control.
• [ ] The phone is unlocked or the carrier has confirmed that another plan can be installed.

Trip plan

• [ ] The destination and validity period match your itinerary.
• [ ] You know whether the plan is data-only.
• [ ] You have Wi-Fi, the activation QR code or activation details, and enough battery for setup.

If a box is unchecked, postpone purchase. A valid plan cannot compensate for a handset that cannot download an eSIM profile.

How to install an eSIM on Samsung Galaxy S20+ 8GB RAM

Read the plan conditions first because installation, activation and validity can be separate events.

1. Prepare the phone

Connect to stable Wi-Fi and charge the phone. Keep the activation QR code on another screen or print it; a code displayed on the same phone cannot normally be scanned by that phone’s camera. Keep manual activation details available if the plan supplies them.

Open Settings → Connections → SIM card manager. The exact wording can vary. Samsung’s guidance may show Add eSIM, Add mobile plan, Add using QR code, or Scan QR code. If there is no add-plan option, return to the compatibility section instead of repeatedly scanning the code.

2. Add the mobile plan

Tap the add eSIM or add mobile plan option, choose the QR-code method and scan the code supplied for your travel plan. Stay on Wi-Fi while the profile downloads. Use manual activation only when the plan explicitly provides the required server or activation data.

Use the Android eSIM installation guide for this Samsung device. The iOS eSIM installation guide is useful only when you are preparing an Apple phone as well.

3. Name and select the line

Give the new line a clear label such as “Travel”. In SIM card manager, confirm that it is enabled and set it as the preferred line for Mobile data when you arrive. Keep the physical SIM selected for calls and messages if needed, and check automatic data switching.

Do not remove the profile just because the phone has not connected at home. A travel plan may not register until it reaches a supported destination network. Keep the QR code and activation details private; they may be usable only once, and forwarding them can expose the profile to another installation.

Activation and first connection abroad

Installing a profile and using it for data are not always the same moment. After landing, disable airplane mode, open SIM card manager, turn on the travel eSIM and select it for mobile data. Enable Data roaming for that line only if the plan’s instructions require it; keep it off for the home SIM to avoid accidental charges.

Wait for registration and restart if necessary. If the plan provides an APN, enter it exactly as supplied, then check the signal with a small web page.

Kaspersky eSIM Store is the app and website where you can choose a destination, purchase an eSIM with a suitable travel data plan and activate it. It is not a mobile operator, does not own the destination network or provide cellular coverage. Review the displayed destination, traffic allowance, validity and activation conditions before purchase.

Practical travel scenarios

You want to keep your usual number

Leave the physical SIM in the phone for calls and messages, and use the travel eSIM for mobile data. Set the travel line for data and turn off automatic data switching if the phone might fall back to the home SIM.

You need data as soon as you land

Install the eSIM over Wi-Fi before departure; at the destination, enable it, select it for mobile data and follow the roaming instructions.

You are crossing several countries

Check that the plan covers the entire route, not only the first arrival city. Supported networks and traffic rules can vary, so allow time for registration after a border crossing.

You use the phone as a hotspot

Check whether tethering is permitted. Enable Mobile Hotspot only after the phone has a stable connection and monitor large updates and video.

You return home

Switch data back to the home SIM, turn off roaming and remove the profile only when you no longer need it. Deleting it does not necessarily cancel a purchase or subscription.

Troubleshooting eSIM problems

There is no EID or Add eSIM option

Check the model number and software version again. A missing EID and add-plan control usually indicate that the regional hardware or firmware does not expose eSIM. Ask Samsung or the carrier about that exact model, especially if it was imported or repaired.

The QR code is rejected

Confirm that the code belongs to this plan and has not already been used. Increase the display brightness, clean the camera lens and keep the code fully visible. Try manual activation only with the exact details supplied by the plan.

The profile installs but there is no service

Check that the eSIM is enabled and selected for mobile data, the destination is covered, roaming is enabled if required and airplane mode is off. Restart the phone. Do not delete the profile while troubleshooting; reinstallation may be limited.

The phone shows signal but apps have no internet

Verify the preferred data SIM, mobile data toggle and APN. Turn off Wi-Fi briefly, disable automatic switching and check roaming for the travel line. If every app fails, record the line name, network indicator and location for support.

Data works slowly or stops after a border crossing

Confirm that the new country is included. Restart, toggle airplane mode once and recheck mobile data. Review the plan’s traffic status before changing settings, and avoid repeatedly removing the eSIM.

Calls or SMS do not work

Many travel eSIM offers are data-only. The profile can provide mobile internet while your normal number remains on the physical SIM. Use messaging or calling apps over data, or keep the home SIM active for its number.

FAQ

Is 8GB RAM enough for eSIM?

Yes. RAM is not the compatibility switch; Samsung Galaxy S20+ 8GB RAM must still pass the EID and SIM-manager checks.

Is Samsung Galaxy S20+ 8GB RAM the same as Samsung Galaxy S20+ 5G?

No. The 8GB designation is commonly associated with LTE, while many 5G versions used 12GB RAM.

Can a factory-unlocked phone use any travel eSIM?

Not automatically. The model, plan and destination network must all support the connection; check the EID, add-plan menu and plan conditions together.

Can I keep a physical SIM and an eSIM active?

Some configurations support two active lines, but behavior depends on the regional model and software. Select one preferred data line.

Should I activate the eSIM before leaving?

Installing before departure gives you reliable Wi-Fi and time to troubleshoot. Read the plan conditions because activation and validity may follow different rules.

What if the EID is present but the plan still fails?

The EID proves that the phone has an embedded SIM identity, not that every plan can be provisioned. Check the destination, device lock, roaming and APN, then contact support.

Final device check and travel eSIM choice

Before you purchase, run the check one last time: confirm the exact model number, confirm that the name is Samsung Galaxy S20+ 8GB RAM, look for the EID, open SIM card manager and verify an add eSIM or add mobile plan control. Then confirm that the phone is unlocked, the destination is included and the travel plan is data-compatible with Android. If the EID or menu is absent, pause and verify the regional version with Samsung or the carrier.

Once the device passes, use Kaspersky eSIM Store’s app or website to choose, purchase and activate an eSIM with a suitable travel data plan. Install over Wi-Fi, keep your home SIM settings intentional, select the eSIM for mobile data at the destination and test a small connection before relying on it for navigation or messaging. This final device check helps ensure that the plan matches the phone you actually carry.
