Vivo X90 Pro 12GB RAM eSIM: compatibility and travel setup

Quick answer: vivo’s official specifications for the X90 Pro 12GB RAM list a configuration with one nano-SIM and one eSIM in several international markets. That supports a yes for the market variants whose official specifications include eSIM. The 12GB RAM label alone does not identify the phone’s sales region or prove that a particular handset has eSIM enabled. No specific carrier or operator market is identified by the device name, so support with any one provider cannot be assumed. Check the exact model and its settings before choosing a travel plan.

This distinction matters because “Vivo X90 Pro 12GB RAM” describes a memory configuration, not a complete regional model number. vivo’s Hong Kong specification page identifies 12GB RAM and lists “Dual Nano SIM (SIM 1 + SIM 2) or Single Nano SIM + eSIM”; the company’s Spain specifications likewise list nano-SIM plus eSIM. Those official listings establish support for those markets, but they do not establish that every X90 Pro sold worldwide has the same SIM hardware, software, or carrier configuration. vivo’s regional pages were checked on 18 October 2026. For the individual phone in your hand, the EID and eSIM controls are the practical checks.

Does Vivo X90 Pro 12GB RAM support eSIM?

The answer depends on which regional version you have. Official vivo documentation confirms eSIM on international-market X90 Pro versions with 12GB RAM, including the Hong Kong and Spain product specifications. A listing that only says “12GB RAM” is not enough to confirm eSIM on an imported, used, or carrier-supplied phone. The RAM amount does not activate eSIM and does not identify the phone’s region.

Treat compatibility as confirmed only when the exact device shows an EID and the settings include an option to add or manage an eSIM. If either is missing, ask the seller or vivo support to confirm using the complete model code and country of sale. A carrier can also restrict a phone or require a software update before eSIM activation. Do not buy a travel plan based only on the model family name or a general compatibility list.

Regional versions and carrier restrictions

Phone specifications can vary by country even when the product name and RAM are the same. Manufacturers may sell different model codes, use different SIM trays, or enable different network features depending on the market. Carrier versions may also have a SIM lock, customized software, or restrictions tied to a contract. The official international X90 Pro pages show eSIM as an option, but that evidence should not be generalized to an unidentified unit from another market.

Before buying a second-hand or imported X90 Pro, request these details from the seller:

• The complete model code shown in Settings → About phone and on the original box.
• The original country or region of sale and whether the software has been changed.
• A live view of the Settings page where an eSIM can be added, if available.
• Confirmation that the phone is unlocked and can use a travel eSIM from another provider.
• Whether the eSIM is currently installed or tied to an account. A used profile should not be assumed transferable.

Check your phone before you buy a plan

Use the following checklist on the handset you will take on the trip. Menu names can vary with Funtouch OS version, region, and language.

1. Check the model code. Open Settings → About phone (sometimes called About device) and note the model number, software version, and region information. Do not share the IMEI publicly.
2. Look for an EID. Open the phone app and enter *#06#. On eSIM-capable phones, the device information screen may show an EID alongside the IMEI. You can also look under Settings → About phone → Status or SIM status. The exact route depends on software. An EID is a strong compatibility signal, but still confirm that eSIM settings are available and that the phone is unlocked.
3. Open mobile network settings. Look under Settings → Network & internet, Mobile network, or SIM card manager for Add eSIM, Download a SIM, or a similarly named option. Vivo may use different labels between regional software releases.
4. Check the carrier lock. If the phone was supplied by an operator, ask that operator whether another provider’s eSIM is allowed. An “unlocked” status should be confirmed before travel rather than inferred from the presence of two SIM profiles.
5. Confirm the destination and plan conditions. Check that the plan includes the country or region you will visit, its validity period, data allowance, activation rules, supported networks, and any tethering restrictions. Do not infer destination coverage from the phone’s eSIM capability.
6. Keep a way to get online during setup. Download or open the installation details while connected to reliable Wi-Fi or another working internet connection. Keep access to the QR code or manual activation details on a second screen or printed copy if the provider permits it.

Check whether your device is compatible before selecting a plan. This check is especially important for regional imports and carrier-issued phones.

Set up eSIM before travelling

Install the profile while you have a stable internet connection and enough time to resolve a problem. Keep your primary SIM active if you need it for calls, account verification, or messages. The exact labels on Vivo can differ, so use the wording on screen and the provider’s activation instructions. For illustrated steps, see the Android eSIM installation guide and, if you are setting up an eSIM on an iPhone instead, the iOS eSIM installation guide.

Add the eSIM with a QR code

1. Connect to Wi-Fi and open Settings → Network & internet → SIM card manager or the closest equivalent. Choose Add eSIM or Add mobile plan. If there is no such option, pause and recheck compatibility before proceeding.
2. Choose the QR-code installation option. Scan the QR code supplied for your purchased plan. If the activation information is provided as a manual code, choose the manual entry route and enter it exactly as supplied.
3. Follow the on-screen prompts to download the profile. Give it a clear label such as Travel data so you can distinguish it from your regular SIM.
4. Keep the profile enabled or disabled according to the plan’s instructions. Some plans begin their validity period when installed; others begin on first connection to a supported network. Check the terms before installation so you know when the clock starts.
5. Set your usual SIM as the default for calls and SMS if you want to keep using its number. Select the travel eSIM for mobile data when you are ready to use it.
6. Turn on data roaming for the travel eSIM only if the plan’s instructions require it. Data roaming is often needed for travel eSIMs to connect to a partner network. Check roaming settings on your home SIM as well to avoid unexpected charges from that provider.
7. Save the activation email, QR code, or manual details until the profile is working. Many QR codes are single-use. Do not delete a profile or scan the same code again unless the plan provider confirms that reinstallation is possible.

Kaspersky eSIM Store’s site and app let travellers choose, arrange, and activate an eSIM with a mobile-data plan for an international trip. The app is not a mobile operator or a network owner. If you want to check what is currently available for your destination, browse the Kaspersky eSIM Store, then compare the destination, allowance, validity, and conditions shown for each plan before proceeding.

When you arrive

If you installed the profile before departure, enable the eSIM when you are ready to use its data. In the SIM manager, choose it as the mobile-data SIM. Turn on data roaming for that profile only when required by its instructions, and check that the eSIM is registered on a supported local network. Automatic network selection is a sensible first setting; if there is no service, try manual selection only among networks permitted by the plan instructions.

A travel eSIM described for mobile data may not include a standard phone number, voice service, or SMS. Use messaging and calling apps over data if that meets your needs, and keep another way to receive critical verification codes. Check the specific plan terms rather than expecting every eSIM to behave like a full local phone subscription.

Common issues and what to check

There is no “Add eSIM” option. Confirm the model code and country of sale, install official software updates, then restart the phone and look through the SIM and network menus again. Check whether an EID appears. If both indicators are missing, ask vivo or the seller to verify the regional version; a menu path cannot enable eSIM on a model that does not support it.

The QR code will not scan. Increase screen brightness on the device showing the code, clean the camera lens, and hold the phone steady. If you received the QR code on the same phone you are configuring, open the provider’s manual setup option if available or display the code on another trusted screen. Confirm that the code belongs to the intended plan and has not already been used. Avoid sharing it because it may contain activation details.

The profile download fails. Check Wi-Fi access, temporarily disable any connection filter that might block the download, and verify that the plan has not already been installed on another device. Confirm that the phone’s date and time are set automatically and that system software is current. If the error persists, contact the plan provider with the error text and model code; do not repeatedly delete and reinstall the profile.

The eSIM is installed but there is no service. Check that the profile is switched on, mobile data is assigned to it, and data roaming is enabled if the plan requires it. Make sure you are in the destination covered by the plan, toggle airplane mode once, and restart the phone. If automatic network selection fails, follow the plan instructions for choosing an allowed network. Network registration may take several minutes after installation or arrival.

The phone connects but data does not work. Confirm that the travel profile is selected for mobile data and that the plan is active and has remaining data. Review the access point name (APN) only if the provider supplied a specific value; do not guess or copy one from an unrelated plan. Check whether a data limit, restricted network mode, or disabled roaming setting is preventing traffic. Test a basic webpage with Wi-Fi switched off to confirm the phone is using mobile data.

The connection is slower than expected. Signal strength, local network congestion, indoor location, handset band support, and the plan’s network arrangements can affect performance. Move to an open area, check that the selected network is included in the plan, and try the recommended network mode. 5G availability is not guaranteed just because the phone supports 5G; the exact regional device, local coverage, network partner, and plan all matter.

The eSIM cannot be used because the phone is locked. Contact the operator that originally supplied the phone and ask about the unlock process. A new plan cannot bypass a carrier restriction. Verify that the restriction has been removed before paying for another eSIM.

When you contact support, include your device model code, software version, destination, the step that failed, and the exact error message. Do not send your QR code, EID, IMEI, or account password in a public post. The seller or operator may request identifiers through an official private support channel to check eligibility.

Travel scenarios

You want to keep your normal number reachable. Install the travel profile before leaving, retain the physical SIM if useful, and assign the eSIM to mobile data after arrival. Review call, message, and roaming charges with your home carrier; keeping a line active can still incur costs even if it is not your data line.

You arrive late and need maps or a ride app. Set up and test the eSIM while you have Wi-Fi at home or in the airport. Save essential booking details offline as a backup. When the travel profile registers, verify that mobile data works before leaving Wi-Fi. This reduces setup pressure but cannot guarantee coverage in every location.

You will cross borders. Check that the plan explicitly includes each country on your route. A phone may support eSIM across regions while a particular plan is limited to one country. Check activation timing and validity so a multi-country journey does not start the plan too early or leave a gap between destinations.

You need a hotspot for a laptop. Check the plan’s tethering terms and try the hotspot only after confirming the phone has mobile data. Some plans or networks may restrict tethering, and the phone’s battery will drain faster while sharing a connection.

Frequently asked questions

Does Vivo X90 Pro 12GB RAM definitely support eSIM?

Official vivo specifications confirm eSIM for X90 Pro versions in several international markets, including listed 12GB configurations. The RAM amount does not prove that an unidentified regional variant supports it. Check for the EID and an add-eSIM option on the exact phone and confirm the model code with the seller or carrier.

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

The international vivo specifications describe a nano-SIM plus eSIM configuration. Which lines can stay active simultaneously depends on the particular regional device and its software. Check the SIM manager; do not assume that two physical SIMs and an eSIM can all be active together.

Where can I find the EID?

Try entering *#06# in the phone app, or check Settings → About phone → Status/SIM status. Menu availability varies. If no EID appears, confirm the exact model and look for an eSIM menu before buying a plan.

Does eSIM support guarantee the plan will work in my destination?

No. The handset must be unlocked, the plan must include the destination and a compatible local network, and the device must be able to connect under local conditions. Check the plan coverage and the device’s regional specifications before purchase.

Will my travel eSIM replace my usual phone number?

A mobile-data travel eSIM may not include ordinary calls, SMS, or a new phone number. You can often keep your main line for calls and messages and choose the travel eSIM for data, subject to the phone’s configuration and your carrier’s charges.

Should I install the eSIM before departure?

Often that is convenient because you can use Wi-Fi and resolve setup issues before travelling. First check when the plan’s validity begins: installation itself may start the period for some plans. Follow the instructions for the plan you selected.

Final check before choosing a travel eSIM

For Vivo X90 Pro 12GB RAM, the best-supported answer is conditional: vivo documents eSIM on several international versions, but 12GB RAM alone does not establish the regional variant in front of you. Confirm the model code, EID, eSIM menu, carrier unlock status, and destination coverage before you pay. Keep your home SIM settings and roaming charges in mind, install the profile using the provider’s instructions, and select the correct line for mobile data when you arrive.

Once compatibility is clear, compare the current destination options, data allowance, validity, and activation rules on the Kaspersky eSIM Store website or in its app. Choose an eSIM plan that fits the trip, then keep its setup details available until you have confirmed that the connection works.
