Vivo X300 Pro eSIM: compatibility, setup and travel use

Short answer: the Vivo X300 Pro can use eSIM on regional versions whose official specifications list it, including the vivo Global model. That does not make every phone sold as “X300 Pro” eSIM capable. The vivo China product page describes two nano-SIM cards, and the India page does not list an eSIM combination in the material checked. Your exact model code, sales region, software and carrier therefore matter. Before choosing a travel plan, confirm that your own phone shows an EID or an option to add or download an eSIM, and check that it is not carrier-locked.

This guide uses “Vivo X300 Pro” exactly as supplied. It does not assume a particular storage configuration or market. vivo’s public specifications can change, and features can vary between regional editions. The regional facts below were checked against vivo’s official Global, India and China product pages on 2 November 2026. For a phone already in your hands, the device’s own settings and the seller’s precise model code are the decisive checks.

Vivo X300 Pro eSIM at a glance

The Global page identifies OriginOS 6 based on Android 16 and lists the X300 Pro’s network setup. It also notes that network functions depend on carrier availability, infrastructure and phone software. The India specifications identify their own market variant with two nano-SIMs, while the China page also specifies dual nano-SIM. These are not contradictions: manufacturers can sell region-specific hardware and software under the same consumer model name. The pages describe the variants available in those markets, not necessarily every import, retailer bundle or later firmware release.

Is eSIM supported on the Vivo X300 Pro?

For the X300 Pro version described on vivo’s Global product page, yes: the page explicitly includes eSIM in its supported SIM configurations. The same page cautions that eSIM availability varies by country or region and carrier, and that network functions can depend on software. vivo’s China page lists two nano-SIM cards. Since the input names no country or model code, the answer for an unspecified unit is possibly, but not guaranteed. Confirm the individual handset before buying a data plan.

Check this exact phone before buying a plan

Use more than one check. A product listing or a generic compatibility table can describe a different region, storage bundle, firmware or carrier variant. The quickest reliable process is to check the handset, compare its model code with its documentation, and confirm that the intended plan supports the destination and the phone’s network configuration.

On-device compatibility checklist

• [ ] Open Settings and search for EID, eSIM, SIM, or Mobile network. Menu names vary by software and region.
• [ ] Check the regulatory or device information screen, the original box, or the phone’s official details for an EID (Embedded Identity Document). An EID is a strong sign that the device has an eSIM identity, but still confirm that eSIM management is enabled and the phone is unlocked.
• [ ] In the SIM or mobile-network settings, look for Add eSIM, Download a SIM, Add mobile plan, or a similar control. If present, open it only to inspect the flow; you do not need to scan or install a plan just to check the menu.
• [ ] Record the exact model number or SKU from Settings → About phone, the box label, or the purchase receipt. Do not publish your IMEI or EID; share sensitive identifiers only with vivo, your carrier or the plan provider when their support process requires them.
• [ ] Ask the seller whether the phone is an official local variant, an imported Global variant, or a China-market unit. Request the model code in writing if you are buying remotely.
• [ ] Confirm the phone is carrier-unlocked. A lock can prevent activation even if the eSIM menu is present.
• [ ] Check that the intended plan covers your destination and that the network bands and local carrier service are suitable. eSIM capability does not guarantee signal or a particular speed.

Search Settings for EID and the add-eSIM control, and compare results with the exact model code. If the checks disagree, pause before purchase and ask vivo or the seller to confirm the regional variant and firmware.

What if the menu is missing?

First search Settings rather than relying on a menu label remembered from another Android phone. The X300 Pro’s interface language, OriginOS build and carrier configuration can change where SIM controls appear. Restart after installing official system updates, then search again. Do not install unofficial firmware or change the phone’s region just to make an eSIM toggle appear; that can create reliability, warranty or security problems and does not add absent eSIM hardware.

If there is no EID and no option to add or download an eSIM, treat the phone as not ready for standard eSIM activation. Confirm the result with vivo support using the model code. If you cannot establish that the handset supports eSIM, use a compatible unlocked phone or ask the destination operator about a physical SIM. A travel router is another option when several devices need connectivity, though it is a separate device and may have its own coverage and power requirements.

If an EID appears but the add-eSIM control does not, check for a carrier restriction, a regional software limitation, a pending update or a disabled SIM feature. Contact vivo or the seller before paying for a plan. The EID alone cannot prove that your exact software build will download a profile from every provider.

Before choosing a plan, check whether your device is compatible.

How to install and activate an eSIM

Set up the phone while you have reliable Wi-Fi, a charged battery and access to the confirmation details for the plan. Read the plan’s own instructions first: some providers start validity when the profile is installed, while others start it at first connection or when you arrive. Do not assume installation and activation mean the same thing. If the provider gives a QR code, keep it available on another screen or printed page; a phone generally cannot scan a QR image displayed only on itself.

1. Check the plan details. Verify the destination or regional coverage, data amount, validity period, supported networks, activation trigger, whether hotspot use is allowed, and how to contact support. Confirm that it is a data plan if you need calls or SMS; many travel eSIM plans do not include a regular number.
2. Connect to Wi-Fi. Leave your existing SIM in place if you need it for account verification or calls. Avoid removing or resetting a line unless the instructions specifically require it.
3. Open the SIM manager. In Settings, search for eSIM or mobile network, then choose Add eSIM, Download a SIM, or the corresponding control available on your X300 Pro software version.
4. Add the profile. Scan the provider’s QR code, or use its manual activation details if offered. If the plan appears inside an app, follow that app’s install flow. Do not scan a QR code from an unknown source.
5. Wait for installation to finish. Keep the phone connected to the internet and do not close the setup screen prematurely. The profile may show as installed but not yet connected; that can be normal before reaching the destination.
6. Label the line. Use a clear name such as “Travel data” so that it is easy to distinguish from your home SIM. Select your preferred line for mobile data and keep the home line available for calls or verification if needed.
7. Set data and roaming options as instructed. When you reach the covered destination, enable the travel eSIM and select it for mobile data. Turn on data roaming for that line only if the plan’s instructions require it. Keep data roaming off for your home SIM if you want to avoid unexpected roaming charges.
8. Check the connection. Wait for the phone to register on a supported network, then test a simple web page or the provider’s connection check. Confirm the active data line and remaining balance in the plan app or account.

For an Android walkthrough, see Kaspersky eSIM Store’s Android installation instructions. For an iPhone walkthrough for another device, see the iOS installation instructions. The menu wording on the Vivo X300 Pro may differ from the generic Android steps; follow the prompts shown on your phone and the plan provider’s instructions.

If you are using Kaspersky eSIM Store, it is an app and website where you can choose, arrange and activate an eSIM with a mobile-data plan for an overseas trip. Check the compatibility of your exact Vivo variant first, then browse the current destination options on the Kaspersky eSIM Store website. This is the general Store homepage for exploring plans; it is not a country-specific tariff page. Check the displayed destination, data allowance, validity and activation terms before selecting a plan.

Using the Vivo X300 Pro for mobile data abroad

A compatible X300 Pro can keep a home number on a physical SIM while using an eSIM for travel data, if the handset and the carrier support that combination. The Global specifications list SIM1 + eSIM1 as one possible configuration. Use the SIM manager to choose which line handles mobile data, calls and messages. The labels and exact combination available on your device may differ. Check whether both lines can remain active in the way you need; dual-SIM standby and simultaneous network use are not identical.

For a short city break, a small data allowance may be enough if you use maps, messaging and browsing sparingly and download maps before departure. For remote work, navigation throughout the day, photo backups or video calls, estimate usage realistically and check whether the plan can be topped up. These are planning examples, not guarantees about the data amount you will need or a recommendation for a particular tariff.

For a multi-country itinerary, compare a plan that covers the whole region with separate destination plans. Confirm the list of included countries and the validity rules, particularly if your route includes a layover, ferry, border crossing or territory with a distinct network. Coverage, available partner networks, speed and local service are determined by the network used in each destination and can vary by location, congestion, device bands and local conditions.

The eSIM profile is not a guarantee of 5G. vivo lists 5G bands for the Global X300 Pro, but whether you connect to 5G depends on the plan, the partner network, the phone’s regional band support, local deployment and signal conditions. 4G may be more widely available or use less battery in some places. If data is unreliable, try selecting an available network automatically, then follow your provider’s guidance before manually choosing a network.

Kaspersky eSIM Store should be understood as the app and website for choosing, arranging and activating a travel eSIM plan. It is not the mobile operator or owner of the destination network. A plan’s service depends on its stated terms and the local network it uses. Review the plan information shown at checkout and keep the provider’s support details handy.

Troubleshooting: when an eSIM will not connect

Frequently asked questions

Does every Vivo X300 Pro support eSIM?

No. vivo Global’s specifications list eSIM combinations for its described model. The China product page lists two nano-SIM cards, and the India page lists two nano-SIMs and does not list an eSIM configuration. Confirm the exact regional version and inspect the phone before buying a plan.

Can I use an eSIM and a physical SIM at the same time?

The Global page lists SIM1 + eSIM1 as an available combination, alongside other SIM choices. Whether both lines can be active for your intended services depends on the device software, chosen combination and carrier. Check the SIM manager and test the setup before travel if both lines are important.

Does an EID mean that any eSIM plan will work?

No. An EID indicates an eSIM identity, but the handset may still be carrier-locked or subject to regional software restrictions. The plan also needs to support your destination and the networks available there. Confirm both device compatibility and plan terms.

Will the eSIM give me a phone number?

Do not assume so. Many travel data eSIMs provide data only, without a regular number for cellular calls or SMS. Messaging and voice apps can work over data. Check the specific plan terms and keep your home number if you need ordinary calls, texts or verification messages.

Should I install the eSIM before the flight?

Follow the plan’s activation instructions. If validity starts at installation, wait until the provider recommends. If it can be installed in advance and activates only at the destination, advance setup may be convenient. Do not delete the profile if it fails to connect until you have checked the provider’s reinstall policy.

Does a China-market Vivo X300 Pro work with a travel eSIM?

The vivo China page checked lists dual nano-SIM rather than a native eSIM option. Do not count on a standard downloadable eSIM for that version unless vivo confirms it for your exact model and firmware. If the handset lacks an EID and add-eSIM control, choose a compatible unlocked device or ask about a physical SIM alternative.

Will my X300 Pro connect to 5G overseas?

Only where the selected plan and local network support it, and where the phone’s regional variant supports the needed bands. Network coverage, software, carrier configuration and local conditions all matter. A 4G connection may be the available option in some areas.

Final check before your trip

For the Vivo X300 Pro, treat eSIM as supported on the Global version specified by vivo, while checking regional and carrier conditions. Do not generalize that result to every China-market, India-market or imported handset bearing the same name. Check for an EID and add-eSIM option, record the exact SKU, confirm the phone is unlocked, and verify that your intended plan covers every destination on your route.

Once compatibility is clear, compare current plan details for data amount, validity, activation timing and destination coverage. The Kaspersky eSIM Store app and website help you choose, arrange and activate an eSIM with a mobile-data plan for an overseas trip. Review the terms for the plan you select, set the correct line for mobile data, and keep your home SIM’s roaming settings under control. A few checks before departure make setup more predictable.
