Xiaomi 12T Pro 128GB eSIM: compatibility and setup

Xiaomi confirms eSIM support for the Xiaomi 12T Pro, with availability varying by country, region and carrier. The 128GB label describes storage; it does not tell you which SIM configuration your phone has. Before choosing a travel plan, check the phone itself for an EID or an option to add an eSIM, and confirm that it is not carrier-locked.

Does Xiaomi 12T Pro 128GB support eSIM?

The model family supports eSIM, but the exact handset should be checked before purchase. Xiaomi lists the Xiaomi 12T Pro with dual SIM configurations that can include one nano-SIM and one eSIM, and its support FAQ says the model supports eSIM. Xiaomi’s specifications also note that eSIM availability can vary by country or region and carrier. This means the brand name and storage capacity are not enough to guarantee the feature on an individual unit.

The same “Xiaomi 12T Pro 128GB” name may refer to units sold in different markets. Regional hardware, software and carrier restrictions can affect eSIM availability. A dual nano-SIM tray does not alone confirm whether eSIM is enabled on that unit.

Storage capacity and 5G connectivity do not by themselves confirm eSIM. Xiaomi’s regional availability note matters: the market where the phone was sold and the market where you use a travel profile may impose different conditions.

Check your exact phone before buying a plan

Check the handset you will take on the trip, not just its listing or a model-family chart.

1. Look for an EID. Open the phone app and enter *#06#. If the device supports eSIM, an EID may appear with the IMEI numbers. You can also check Settings under About phone or the status/SIM information screens. Menu names vary by MIUI or HyperOS version and region. Do not share the EID publicly; it is a device identifier.
2. Look for the add-eSIM control. Open Settings and search for “eSIM” or “Add eSIM”. Depending on software version, mobile network settings may be under Settings → SIM cards & mobile networks, then a SIM management or add mobile plan option. If the option is missing, check for a system update and restart once; a missing menu can also reflect the regional software build or a carrier restriction.
3. Check the SIM configuration. Inspect the SIM tray and current SIM settings. Xiaomi lists both nano-SIM + eSIM and nano-SIM + nano-SIM possibilities for the 12T Pro in some markets. A physical tray with two nano-SIM positions can coexist with an eSIM capability on a supported version; the tray alone is not a complete compatibility test.
4. Confirm the regional version. Ask the seller for the full model code, country of sale, and written confirmation that eSIM can be added on that unit. If the phone was bought through a carrier, ask whether it is unlocked for another provider’s profile.
5. Verify before payment. Use the phone’s EID/menu and the compatibility information for the intended plan. If the device has no EID and no add-eSIM option after you have checked the exact build with Xiaomi or the seller, do not assume that a travel plan will work.

Compatibility checklist

• [ ] The phone displays an EID or has an eSIM addition option.
• [ ] The exact Xiaomi 12T Pro unit is not locked to a carrier that blocks the intended profile.
• [ ] The operating system is up to date and the phone can connect to Wi-Fi during installation.
• [ ] The plan supports the country or region on your itinerary and the expected travel dates.
• [ ] You understand whether the plan starts on installation, first network connection, or a scheduled date, according to its terms.
• [ ] Your usual SIM remains available for calls or SMS if you need it, and you know which line is selected for mobile data.

If you cannot verify eSIM on the phone before buying, ask the seller or Xiaomi support to confirm the full regional model code. A generic “Xiaomi 12T Pro” compatibility result is useful background, but it is not a substitute for checking the unit in hand when regional variants are involved.

For a used phone, ask the seller to demonstrate the menu on that unit. A screenshot or box from another country may refer to a different configuration. Compare the model code and software region if the eSIM menu is absent or the seller cannot confirm unlock status.

For an additional check, review your device compatibility before choosing a plan. You can also browse current destinations and eSIM travel plans on the Kaspersky eSIM Store website; it helps you choose and activate a travel data eSIM, but cannot change a regional device restriction or carrier lock.

Install and activate an eSIM

Install the profile while you have a stable internet connection, such as Wi-Fi. Keep the QR code available on another screen or print it, because the phone cannot normally scan a QR code displayed on its own screen. Follow the plan’s instructions if they offer in-app or manual installation.

Xiaomi 12T Pro setup steps

1. Confirm compatibility and unlock status. Look for the EID or Add eSIM option, and check that the phone is not carrier-locked.
2. Connect to Wi-Fi. Keep a stable connection while the profile downloads. Keep the QR code on another screen or print it.
3. Open eSIM settings. Search Settings for “eSIM” or “Add eSIM”; on Xiaomi, the control is usually under SIM cards and mobile networks. Labels depend on MIUI or HyperOS version.
4. Scan the activation code. Follow the prompts, or enter provider-supplied manual details exactly as shown.
5. Wait for installation. Leave Wi-Fi on until the profile is added, then label it “Travel data” to identify it.
6. Choose the data line when ready. At your destination, enable the travel profile, select it for mobile data, and enable roaming for that eSIM if the plan requires it. Check that the home SIM is not selected for data.
7. Allow network registration. It can take several minutes to connect. Check activation terms before deleting or reinstalling the profile.

For more guidance, see the Android eSIM installation instructions. The iOS eSIM installation instructions describe Apple menus; use your Xiaomi’s own menu labels.

Before you leave

Install in advance if the plan allows it, but check when validity begins: at installation, first connection, or a scheduled time. Save the instructions for offline access and keep the activation code secure. Before departure, confirm that the profile is enabled at the right time and that mobile data is assigned to it. A data-only plan does not replace your number, calls or SMS; internet calls use data and require an active app account.

Using eSIM for travel data

After setup, select the travel eSIM as the mobile-data line in SIM settings. Keep your regular SIM for calls or texts if needed, and check your home carrier’s roaming terms. If the plan requires data roaming, enable it for the eSIM only. Xiaomi menus may show separate controls for each line; read the line name before changing a setting. Review automatic data switching so the phone does not move data back to your home line.

Kaspersky eSIM Store is an app and website where you can choose, arrange and activate an eSIM plan for mobile data on an international trip. Check the selected plan’s destinations, data allowance, validity, activation conditions and supported networks. For a multi-country trip, verify that every stop is included; a regional plan covers only the countries named in its terms. Availability and performance depend on the selected plan and local conditions.

Travel data eSIMs generally do not provide an ordinary phone number, voice calls or SMS unless the plan explicitly says otherwise. Messaging and internet calling apps can use the data connection. Keep access to your usual number if you need it for verification codes.

Common problems and checks

There is no EID or Add eSIM option

Search Settings and inspect identifiers with *#06#; restart the phone and install any available update. Then confirm the regional model code with the seller or Xiaomi support. Xiaomi confirms eSIM support for the model family but warns availability may vary by region and carrier. If the exact phone has no EID or setup control, do not assume a plan will work.

The QR code will not scan

Display it on another device or print it, increase brightness and avoid glare. If the code may already have been used or the profile partly installed, contact the plan provider before trying again; a single-use activation code may not reset after deletion.

The profile does not download

Check Wi-Fi, available storage, automatic date and time, and any pending software update. If the code is reported invalid or used, stop retrying and ask the provider to check activation status.

The eSIM is installed but there is no service

Make sure the profile is on and selected for mobile data. Check destination, activation date and validity, then toggle airplane mode or restart. Enable data roaming for the eSIM if instructed, and confirm the phone is unlocked. A valid profile may still be outside the plan’s service area or activation window.

Mobile data is connected but apps do not load

Check the remaining allowance and validity, and confirm the travel profile is the data line. If the provider gives an APN (access point name), enter that exact value; do not copy an APN from another plan. Start with automatic network selection and follow provider guidance if manual selection is needed.

The home SIM starts roaming

Review data-line selection and roaming controls for both SIMs. Choose the travel eSIM for data and disable automatic data switching if available. Keeping the home line on for calls does not prevent voice or SMS roaming charges under your carrier’s terms.

The plan cannot be moved to a replacement phone

A profile may be limited to one device or installation. Check transfer rules before deleting it or resetting the Xiaomi 12T Pro. Contact the provider if the phone is replaced; model-family eSIM support does not mean an installed profile is freely transferable.

FAQ

Is eSIM supported on Xiaomi 12T Pro 128GB?

Xiaomi confirms eSIM for the Xiaomi 12T Pro family. The 128GB label does not identify the regional cellular configuration, so check for an EID or Add eSIM option on your exact phone and confirm it is unlocked.

Can the phone use a physical SIM and eSIM?

Xiaomi lists nano-SIM + eSIM and dual nano-SIM configurations for the 12T Pro in supported markets. Check your handset’s SIM settings to confirm its configuration.

Where can I find the EID?

Enter *#06# in the phone app and look for an EID, or check About phone or SIM status. Search Settings for “EID” or “eSIM” if the menu differs; do not post the identifier publicly.

Does a travel eSIM include calls and texts?

Usually it is for mobile data and does not include a regular number, calls or SMS unless its terms say so. Internet calls and messages can work through compatible apps.
