Vivo X100 Pro 512GB eSIM: compatibility and installation

Can the Vivo X100 Pro 512GB use an eSIM for mobile internet while you travel? The answer depends on the market version. Vivo’s current international specifications for the 16 GB + 512 GB configuration list two nano-SIMs or one nano-SIM plus an eSIM. Vivo’s official China and India specifications for the corresponding 512 GB phone list two physical nano-SIMs and do not list eSIM. Storage capacity alone is not enough to confirm compatibility.

The practical verdict is conditional: an international Vivo X100 Pro 512GB may support eSIM, while a China-market or India-market unit may not. Check the phone in your hand before purchasing a plan. The decisive signs are an EID in device information and an Add eSIM or similar command in mobile-network settings. If neither is present, do not assume that a QR code or a system update can add eSIM capability.

What the exact Vivo X100 Pro 512GB variant means

“Vivo X100 Pro 512GB” preserves the requested storage variant, but it does not identify one worldwide hardware and software configuration. Official Vivo pages show several memory combinations, including 16 GB + 512 GB, while the SIM description changes by region. International pages describe a choice between two nano-SIMs and one nano-SIM plus eSIM. Other regional pages describe the same model family and 512 GB storage with two nano-SIMs only.

That difference matters for a travel eSIM. A phone can have the same name, cameras, processor and storage while using a different modem configuration, SIM tray or firmware family. A marketplace may shorten “16 GB + 512 GB” to “512GB,” so check the sales market and exact model code as well as the name.

Compatibility summary

Do not use 5G, Dual SIM Dual Standby, a dual-SIM tray or 512GB storage as proof of eSIM support. These describe network or physical-SIM capability, not whether the phone can download an eSIM profile. A compatible phone must also be unlocked, eligible under the selected plan and able to register on a supported local network.

Why region and carrier matter

Vivo notes that actual network functions depend on the carrier network, infrastructure and software version. The X100 Pro 512GB may be an international Funtouch OS unit, a local retail model, a carrier-supplied phone or a China-market OriginOS unit. These variants can expose different SIM functions. An operator can also restrict activation or require the device to be unlocked.

Does Vivo X100 Pro 512GB support eSIM?

For an international version, official Vivo specifications give a positive answer: the network section lists “2 nano SIMs (SIM1 + SIM2) or 1 nano SIM + eSIM.” This confirms that the relevant international configuration can use a digital SIM profile alongside one physical nano-SIM.

The answer is not universal for every Vivo X100 Pro 512GB. Vivo’s official China specification identifies the V2324A 16 GB + 512 GB model as dual-nano-SIM. Vivo’s official India store page for the X100 Pro 16GB+512GB (5G) also lists “2 nano SIMs (SIM1 + SIM2)” and does not list eSIM. Treat those versions as physical-SIM-only unless the phone clearly shows an EID and add-eSIM control.

So the direct answer for this exact requested variant is: Vivo X100 Pro 512GB can support eSIM when it is a regional version whose official specification and device menus include eSIM, but it cannot be assumed compatible across all markets. Verify the individual device before payment.

How to verify your phone before buying a plan

Use the phone itself as the final check. Reseller descriptions can be incomplete, and an international specification does not confirm a different regional unit.

Check for an EID

An EID is an identifier associated with the eSIM component. It is a strong sign of eSIM hardware, although a carrier or region can still limit activation.

1. Open Settings and search for EID, eSIM or SIM.
2. Check About phone, Status, IMEI information or a similarly named information page.
3. You can also try *#06#. On a compatible device, the information screen may show an EID alongside IMEI numbers.
4. Keep the full EID private. Share it only with a trusted support channel if specifically requested.

If the phone shows only IMEI numbers and no EID, that is a warning that this regional version may not contain eSIM capability. Continue only if Vivo or the seller can identify a supported configuration.

Check for the add-eSIM control

Menu names vary with Funtouch OS, language and market. Look under Settings → Mobile network, SIM card & mobile network, or Network & internet → SIMs. A compatible unit may show Add eSIM, Add mobile plan, Set up eSIM or a similar command. The command may be inside SIM management or behind a plus sign.

There are three useful outcomes:

• EID and add-eSIM are present: the phone is technically ready for a profile, subject to plan and carrier requirements.
• The command is present but activation fails: check for a carrier lock, regional restriction, network problem or different activation method.
• No EID and no command: treat the Vivo X100 Pro 512GB as physical-SIM-only for this use case.

For a quick decision before selecting a plan, Check your device and record the result of both checks. Ask the seller for the model code and intended market if the phone is imported or refurbished.

What to check before purchasing an eSIM plan

Device compatibility is the first filter, not the final one. Complete this checklist while you still have reliable internet and time to ask questions.

• Exact variant and market: confirm the listing is Vivo X100 Pro 512GB, not another X100 model or storage version, and ask whether it is international, China or India.
• EID and menu: confirm both the EID and an add-eSIM command; keep the complete identifier private.
• Lock and software: make sure the phone is unlocked, install available official updates, and recheck the menu. An update cannot be assumed to add hardware support.
• Plan and destination: verify the destination, local-network support, data allowance, validity, activation rule, top-up and refund conditions. These travel plans are for mobile data and do not include a normal number, voice or SMS unless stated.
• Installation: have Wi-Fi available and keep the QR code or activation details on a second screen if necessary. A compatible international unit may use one physical nano-SIM plus eSIM instead of two physical SIMs.

How to install and activate eSIM on Vivo X100 Pro 512GB

Before installation

1. Connect the Vivo X100 Pro 512GB to stable Wi-Fi and charge the phone.
2. Open your order or profile in Kaspersky eSIM Store and locate the QR code or manual activation details.
3. Confirm the destination, allowance, validity and activation rule. If two physical SIMs are installed, decide which can be disabled; a compatible unit may support one physical nano-SIM plus eSIM, not three active lines.

For platform-specific guidance, see the Android installation instructions and the iOS installation instructions.

Add the profile

1. Open Settings → Mobile network or SIM management and choose Add eSIM, Add mobile plan or the closest option. If it is missing, repeat the compatibility check.
2. Scan the QR code from another screen, or enter the SM-DP+ address and activation code exactly as supplied.
3. Wait for the download, label the line Travel data, and confirm that the profile is enabled. Installation and activation may occur at different times.

Select eSIM for mobile data

In mobile-network settings, set the travel eSIM as the preferred line for Mobile data. Turn off automatic data switching to prevent accidental use of the home SIM. If required by the plan, enable data roaming for the travel eSIM and review the home line separately.

Leave automatic network selection enabled for the first connection unless the plan gives different instructions. A signal icon does not prove that data is working, so test a simple webpage after the profile registers.

Using the eSIM during a trip

Before departure

Install the profile at home on stable Wi-Fi, but check when validity begins: some plans start at installation and others at first connection in the destination. If unclear, ask support first. Keep the primary SIM only if needed and disable automatic data switching.

At arrival

1. Turn on the travel eSIM, select it for mobile data and enable roaming if required.
2. Wait for registration. If there is no connection, toggle airplane mode once and check the network and access-point settings specified by the plan.
3. Test a small amount of data before navigation, video or hotspot use.

This travel eSIM is for mobile internet, not automatically a replacement for your usual phone number. Calls and SMS may continue through the primary SIM or messaging apps. Hotspot use may be restricted. Track usage in mobile-network settings or the app; background updates and hotspot sessions can consume data quickly. Do not remove the eSIM unless instructed, since deletion can make reinstallation difficult.

Troubleshooting common problems

The QR code will not scan

Increase display brightness, clean the lens, hold the phone steady and keep the whole code visible. Use another screen if necessary. If offered, enter manual activation fields carefully and do not repeatedly scan a single-use code on different devices.

The profile cannot be added

Confirm the EID, add-eSIM command, Wi-Fi and storage. Restart and try again from SIM management. If the option is missing, recheck the region: China or India devices may be physical-SIM-only.

The eSIM is installed but there is no signal

Make sure the profile is enabled and selected for data. Check roaming when required, toggle airplane mode, confirm coverage and network selection. A carrier lock can prevent registration.

Signal appears but apps are offline

Verify the data SIM and disable automatic switching. Review access-point settings only when the plan specifies them; do not copy an unrelated APN. Test a browser.

Data is being charged on the home SIM

Set the travel eSIM as the data line, disable automatic switching and turn off home-line data if you do not need it. Check usage again.

The plan is not usable at the destination

Compare destination, validity and network requirements with the plan. Coverage depends on the local operator and current conditions. If blocked, note the model code, region, software version and error message before contacting support. Do not delete the profile until advised.

FAQ

Is every Vivo X100 Pro 512GB eSIM-compatible?

No. International Vivo specifications list one nano-SIM plus eSIM, while official China and India specifications for corresponding 512GB versions list two nano-SIMs only. The market version, firmware and carrier conditions decide the result. Check the EID and settings on the phone.

Can a physical SIM and an eSIM work together?

On a compatible international unit, Vivo describes two nano-SIMs or one nano-SIM plus eSIM. You can often keep one physical SIM and add the travel eSIM, but two installed physical SIMs may require one line to be disabled. Active-line behavior depends on firmware and carrier.

Does the travel eSIM include a phone number?

Not usually in this mobile-data use case. Voice calls, SMS and an ordinary phone number are not included unless the selected plan says so. Messaging apps can work over the eSIM data connection.

What is Kaspersky eSIM Store?

Kaspersky eSIM Store is an app and website that helps you choose, arrange and activate an eSIM with a suitable plan for mobile internet during an overseas trip. It is not a mobile operator, network owner or provider of the underlying coverage.

Conclusion

The Vivo X100 Pro 512GB is a regional eSIM case, not a universal yes-or-no model. An international unit whose official specification and settings show eSIM can suit a travel data plan. China-market and India-market versions may list two nano-SIMs only.

Kaspersky eSIM Store helps you choose and activate an eSIM with a suitable plan for mobile internet in a foreign destination. Review the destination, allowance, validity and activation conditions; it is not a mobile operator or network provider.

Final device check before your trip

• The exact name is Vivo X100 Pro 512GB, with the correct model code and sales region.
• An EID appears in the phone’s information screen.
• Add eSIM or an equivalent option appears under mobile-network settings.
• The phone is unlocked and updated, and the selected plan covers the destination.
• Installation will take place on reliable internet, with the travel eSIM selected for mobile data.
• Roaming is enabled when required, automatic switching is disabled, and a small data test works on arrival.

If the EID or add-eSIM option is missing, pause before payment and confirm the region with the seller. If both are present, choose a plan for the destination, keep its activation details secure and follow the steps above. This helps prevent purchasing a plan the particular Vivo X100 Pro 512GB cannot use.
