Vivo X100 Pro 256GB eSIM: compatibility and setup guide

The Vivo X100 Pro 256GB may support eSIM, but storage capacity alone does not tell you which regional version you own. vivo’s official specifications for several international-market X100 Pro versions list either two nano-SIM cards or one nano-SIM plus an eSIM. That confirms eSIM capability for those listed versions; it does not prove that every phone sold as “Vivo X100 Pro 256GB” has the same hardware, software or carrier eligibility. Check the exact handset before choosing a travel plan.

For the confirmed compatible version, you can add a digital SIM profile and select it for mobile data while keeping a physical SIM active, subject to the phone’s dual-SIM configuration and the local operator’s service. An eSIM plan is useful when travelling because it can provide mobile data without replacing your physical card. Your ability to install a profile depends on the phone version, its software, whether it is carrier-unlocked and whether the operator in the country where you will use the service supports that plan.

Does Vivo X100 Pro 256GB support eSIM?

The model family includes eSIM-capable regional versions, but the name and 256GB storage specification are not enough to confirm your particular handset. vivo’s international product specifications, including pages for markets such as India and Taiwan, describe a SIM configuration of two nano-SIMs or one nano-SIM plus eSIM. The global specification page lists the same choice. The manufacturer’s China-market X100 Pro page describes a separate market release, so do not assume that its firmware and SIM features match an international version simply because the exterior and product name look similar.

The important distinction is between a feature documented for a regional product and the status of the individual phone in your hand. “256GB” describes storage; it is not a universal X100 Pro model code. Retail listings may also use the same capacity label for imported or refurbished devices. A country where an eSIM plan is sold does not make every X100 Pro compatible, and a compatible phone does not guarantee that every operator will issue or activate an eSIM for it.

The practical answer is therefore conditional: if your specific Vivo X100 Pro 256GB has an EID and offers an option to add a mobile plan/eSIM, and the phone is not carrier-locked, it can use a compatible eSIM profile. If the EID and eSIM controls are absent, do not buy a plan on the assumption that a software update or a 5G label will add the feature. Ask the seller or vivo support to confirm the exact model code and market version.

Why the regional version matters

Manufacturers sometimes sell phones with the same family name but different combinations of radios, SIM hardware, firmware, bundled software and network approvals in different markets. vivo’s own X100 Pro specifications make the regional distinction visible: international product pages document an eSIM option, while a local-market product page can describe a release with different software and market-specific specifications. A listing that only says X100 Pro and 256GB leaves out the information needed to map your device to one of those releases.

This is a device-market question, not a claim about the geographic status of eSIM. A country may permit and offer eSIM service while a particular imported phone lacks the feature. Conversely, a phone version with eSIM hardware can be used only where the chosen operator supports the relevant service and issues a profile to eligible customers. Availability for local residents, visitors, prepaid customers and roaming customers can differ. The operator’s current terms for the country where you will connect determine service eligibility.

Before purchase, ask the seller for the full model or product code, the original sales market, and confirmation that the exact unit supports eSIM. If the device is used, check that it is not restricted to a carrier and that an eSIM profile has not already been installed or left in an error state. If you are buying in one country for use in another, verify both the device’s eSIM feature and the destination operator’s provisioning rules. Do not infer the answer from a listing photo, the number of SIMs in the box description, the processor name or a generic X100 Pro specification table.

A carrier lock is separate from eSIM hardware. A phone may have a built-in eSIM function but still refuse a profile from another operator because the original carrier has restricted it. Ask the carrier that sold the handset to remove or confirm the absence of a SIM lock. For a travel profile, also check the plan’s destination, supported network, data allowance, validity period, activation conditions and any device-specific requirements before payment.

Check compatibility on your own phone

Use both an on-device check and a model check when possible. Menus can vary by Funtouch OS/OriginOS version, region and language, so names below may be slightly different. Do not share the full EID or IMEI publicly; these identifiers are sensitive device information and are normally needed only for a trusted operator or support process.

Compatibility checklist

• [ ] Confirm the full model code and original sales market from Settings, the box label or the purchase paperwork.
• [ ] Open the dialler and enter *#06#. Check whether an EID appears alongside the IMEI numbers. You can also look under Settings → About phone → Status or a similar device-information page.
• [ ] Open Settings → Mobile network (sometimes called SIM card & mobile network) and look for eSIM, Add eSIM, Add mobile plan or Download a SIM.
• [ ] Check whether a mobile plan can be added without inserting a second physical SIM. Do not complete a paid activation just to test the menu.
• [ ] Confirm the phone is unlocked and that the eSIM operator supports this exact phone version and the intended destination.
• [ ] Check the offer’s terms for when the validity period starts, whether data roaming must be enabled and whether the profile can be reinstalled or transferred.

Check whether your device is compatible

What to prepare before installation

Install the eSIM while the phone has a stable internet connection, preferably Wi-Fi. Keep the QR code or manual activation details accessible on another screen or in a secure place; most phones cannot scan a QR code displayed on their own screen. If the profile is delivered in an account, sign in to that account before starting. Make sure the phone has enough battery, and do not reset the device or remove a profile midway through setup.

Read the plan terms before you install it. Some profiles begin their validity period when installed, while others start when they first connect to a supported network; the provider’s instructions define the trigger. Check whether installation must happen before departure, whether activation should wait until arrival and whether the profile can be installed only once. Keep your primary number available if you rely on it for calls or messages. A travel data eSIM may not include a regular phone number, voice calls or SMS unless the selected plan explicitly says otherwise.

How to install and activate an eSIM on Vivo X100 Pro 256GB

The exact wording of Funtouch OS or OriginOS menus can differ by software build. Use the on-screen labels as a guide, and consult the Android eSIM installation instructions if you need screenshots or another supported setup route. The iOS instructions are for iPhone users; this Vivo phone runs Android, so follow the Android steps for this device.

1. Confirm compatibility and unlock status. Verify that your own phone shows an EID and an eSIM-add option, and check with the carrier if the phone was sold under a contract.
2. Connect to Wi-Fi. Keep the connection stable until the profile has downloaded and the phone confirms that it was added.
3. Open mobile-network settings. Go to Settings → Mobile network or the equivalent SIM settings page. Choose eSIM or Add eSIM/mobile plan.
4. Scan or enter the activation details. Scan the QR code supplied for the selected plan using the phone’s setup screen. If scanning is unavailable, enter the activation code manually only if the provider supplied one.
5. Review the profile prompt. Confirm that the displayed plan/provider details are the ones you expect, then allow the phone to download and install the profile. Keep the screen open while it finishes.
6. Name the new line. Choose a label such as “Travel data” so you can distinguish it from your primary SIM. A label is only for your own settings and does not change the plan.
7. Choose when to use it. If you are not at the destination yet, leave the travel profile installed but switch off its line or mobile-data use until the plan’s terms say it is time to connect. Do not delete it as a way to pause it.
8. Set the data line. In the SIM or mobile-network settings, select the travel eSIM for mobile data when you are ready. Keep your regular SIM selected for calls and texts if you want to continue using its number, and review its roaming settings to avoid unwanted charges.
9. Enable data roaming only if required. Some travel eSIM profiles require roaming to connect to their partner network. Follow the plan’s instructions for the eSIM line; check that roaming is not enabled on your home SIM unless you intend to use it.
10. Wait for network registration. After arrival, allow a few minutes for the profile to connect. If it does not, use the troubleshooting steps below and check the provider’s activation instructions before changing or deleting the profile.

Using the eSIM for mobile data while travelling

Once the eSIM is active, select it as the line for mobile data. If you keep your home SIM enabled, the phone may offer separate controls for calls, messages and data. Review the defaults carefully: the data line should be the travel profile if you want to use its allowance. Disable automatic data switching if your phone could move data back to the home SIM. Keep the home line on only if you need its number for incoming calls, account verification or messages and understand the roaming terms from that carrier.

At the airport, connect to Wi-Fi and check that the travel eSIM is switched on, selected for data and allowed to roam if its instructions require it. Turn off airplane mode, wait for registration, and verify that mobile data works by opening a simple web page. If the plan is designed to start on first network connection, this may be when its validity begins. If you want the plan to start later, follow its specific activation instructions and avoid switching the line on prematurely.

A travel eSIM is primarily a mobile-data option. It does not automatically replace your main number, and a data-only plan may not support standard calls or SMS. You can use internet-based messaging and calling apps over the data connection, subject to their own requirements. Keep the QR code and account access private, and retain the plan confirmation until you have finished the trip.

Common problems and checks

There is no eSIM or Add mobile plan option

Check the full model code and the phone’s original market first. Restart the phone and install available official updates, then look again in both the mobile-network menu and the device-status information. If no EID is displayed and there is no eSIM control, ask vivo or the seller to confirm whether that exact version includes eSIM. A regional product page for another X100 Pro does not override the specifications of your individual handset.

The QR code will not scan

Increase the brightness on the screen showing the QR code, clean the phone camera and keep the code fully visible. Make sure the QR code has not been cropped or blurred. If the provider offers manual entry, use the activation details exactly as supplied. If the code was already used, do not keep retrying; contact the provider to check whether the profile is active or needs to be reissued.

The profile downloads but does not connect

Check that the eSIM line is enabled and selected for mobile data. Turn airplane mode on briefly and then off, restart the phone, and allow time for the network to register. Confirm that the plan is active, covers the country you are in and has not expired or exhausted its allowance. If the instructions require data roaming, enable it for the travel eSIM. Check for a manual network-selection instruction from the provider before changing network selection yourself.

The phone shows signal bars but apps have no internet

Verify that mobile data is enabled and assigned to the travel eSIM. Check whether the phone is using Wi-Fi with a captive portal or an unstable connection; temporarily turn Wi-Fi off to test mobile data. Review any access-point settings only if the provider has supplied exact values. Check the plan balance or usage in the relevant account, and confirm that background data or a device data limit has not been disabled.

The home SIM is using data or roaming charges appear

Reopen SIM settings and make the travel eSIM the selected data line. Turn off automatic switching between SIMs if available. For the home line, disable data roaming unless you intentionally need it and have checked the carrier’s charges. A dual-SIM phone can keep one line for calls and another for data, but the chosen defaults matter.

The phone says the plan cannot be added or is unsupported

Check the phone’s carrier-lock status, region/version and software build. Confirm that the plan is intended for this device and that its activation code is valid and unused. If the phone has an EID but the provider declines the device, ask the provider whether it accepts this exact model code and market release. Save the error text and order reference; do not post your EID or activation code publicly.

Data is slow or unavailable in one place

Coverage and speed vary with the local network, building, congestion, terrain and roaming arrangement. Move to an open area, restart the connection, and check whether the selected network matches the provider’s instructions. Confirm that the country and plan remain valid. The phone’s 5G capability does not guarantee 5G access: both the operator’s network and the selected plan must support it at your location.

Frequently asked questions

Can every Vivo X100 Pro 256GB use an eSIM?

No single answer applies to every regional unit. vivo lists eSIM on several international X100 Pro specifications, but the 256GB storage label does not identify the phone’s market version. Check its model code, EID and Settings menu before buying a plan.

Does the 256GB storage option determine eSIM support?

No. Storage is not a reliable identifier of the SIM hardware. Confirm the market version from the model code and test the handset itself for an EID and an eSIM-add option.

Does eSIM mean my phone is unlocked?

No. eSIM support describes device capability. A carrier can still lock a handset to its service. Ask the carrier or seller to confirm that the phone can accept a profile from the provider you intend to use.

Can I keep my usual number?

Usually you can leave a physical SIM enabled for calls and messages while selecting the travel eSIM for mobile data, provided the device and carriers allow that configuration. Check roaming charges on the home line. A data-only travel plan does not supply a replacement phone number unless its terms explicitly say so.

Before your trip: verify the phone, then choose the plan

For a Vivo X100 Pro 256GB, start with the individual handset rather than the name in a shop listing. Confirm the sales region and full model code, look for its EID, and make sure Settings offers an eSIM installation option. Then confirm that the phone is unlocked and that the operator behind the chosen eSIM plan accepts the device in your destination.

Once compatibility is clear, choose a plan that covers your actual itinerary and fits the trip’s duration and data needs. Check when validity starts, whether data roaming is required for the eSIM, and what the plan includes. 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. Complete the compatibility check before payment, and keep the profile and home-SIM settings clear so you know which line is providing data after you arrive.
