Xiaomi Poco X3 Pro and eSIM: How to find out support in 5 minutes

Xiaomi Poco X3 Pro remains a popular choice among gamers and fans of powerful technology even years after its release. SIM-Many owners are wondering: does their device support this technology? The answer is not as obvious as it seems - the manufacturer does not always advertise this feature, and technical specifications can be misleading.

In this article, we’ll look at all the ways you can test for eSIM support on the Poco X3 Pro, from analyzing official documents to hidden engineering menus. You’ll learn which firmware versions can affect virtual SIM, how to circumvent carrier restrictions, and what to do if your device doesn’t support the technology. And we’ll compare the Poco X3 Pro to other Xiaomi models on this parameter — the data is presented in a handy table.

Important: information is relevant for all regional versions of Poco X3 Pro (M2012K11AG, M2012K11AI, M2012K11AC), including global (Global), Chinese (China) and Indian (India).

1.Official data: What Xiaomi says about eSIM support

The first and most reliable source is the manufacturer's documentation, but with the Poco X3 Pro, the situation is mixed.

• 📄 Specifications on the Xiaomi website: On the official pages of Poco X3 Pro (including archival versions) does not mention eSIM in any region, which is a signal that support is unlikely.
• 📦 Box and instruction: There are no stickers or notes about the virtual SIM. Even in the extended guides (for example, for the European market), this feature is not mentioned.
• 🔧 Service centers: For requests in support of Xiaomi comes the standard answer: "Poco" X3 Pro is not certified to work with eSIM. But that doesn't always mean hardware limitations -- sometimes software locking.

However, there is a caveat: some Xiaomi models (such as the Mi 12T Pro or Redmi Note 11 Pro+ 5G) received support for eSIM only after firmware updates. Theoretically, the Poco X3 Pro could get it in the future, but given the age of the device (released in March 2021), this is unlikely.

2. Technical specifications: what hides the processor and modem

The Poco X3 Pro is built on the Qualcomm Snapdragon 860 platform, a relabeled version of the Snapdragon 855+.This chipset supports eSIM at the hardware level (via the X50 5G modem), but the implementation depends on the manufacturer.

Key points:

• 📡 modem: X50 5G In theory, it is compatible with eSIM, but Xiaomi could disable the function in the BIOS Or firmware, POCO F3 The same chipset also does not support virtual SIM.
• 🔄 Dual Sims: The device features a physical tray for two nano-SIMs (a hybrid microSD slot).In most cases, Xiaomi doesn't implement eSIM in phones with two physical slots.
• 🛠️ Firmware: Even if there is hardware support, without the appropriate software, eSIM will not work. MIUI 12/13/14 POCO X3 There is no virtual activation menu SIM.

By comparison, the Google Pixel 4a on the Snapdragon 730G (a weaker chipset) supports eSIM, while the Poco X3 Pro does not. This confirms that the restriction is artificial.

3.Practical Check: 3 Ways to Learn About ESIM Support

If the official data doesn't convince you, we'll go to practical methods that will help you to identify even hidden support.

Method 1: USSD code for checking eSIM

Some operators (e.g. Tinkoff Mobile or Tele2) grant USSD-- Diagnostic teams:

*#06#

If the phone supports eSIM, an additional partition with an EID (eSIM identifier) may appear in the response. For the Poco X3 Pro, this method usually does not work, but it is worth a try.

Method 2: Hidden Engineering Menu

Go to the engineering menu by code:

##4636##

In the Phone Information section, look for items related to IMS or eSIM. The absence of them is a bad sign.

Method 3: Applications for diagnostics

Install one of these apps and check for eSIM:

• 🔍 eSIM Checker (shows you the EID support)
• 📱 Device Info HW (tab SIM Card)
• 🛠️ AIDA64 (telephony)

Enter #06# and check it out. EID|Go to the engineering menu (#4636##*)|Install eSIM Checker from Google Play|Check the settings. SIM-card MIUI

-->

Attention! If neither method has shown eSIM support, but you still doubt it, try activating a virtual SIM via an operator. For example, MTS and Beeline allow you to do this online. 99% of the time, the Poco X3 Pro will give an error "The device does not support eSIM."

4. Comparison with other Xiaomi models: who supports eSIM

To understand why the Poco X3 Pro is not featured, look at other Xiaomi devices, and we have compiled a compatibility table (June 2026):

As you can see, Xiaomi is selectively implementing eSIM, preferring flagships and new models. Poco X3 Pro belongs to the budget-gaming segment, where such a feature is not considered a priority. Moreover, even in the POCO lineup, support appeared only with the F5 Pro (2023).

💡

If your Poco X3 Pro is released before 2022, the probability of eSIM support tends to zero – the manufacturer has not updated the firmware for older models with this feature.

5. Alternative solutions: what to do if eSIM is not supported

If the check confirmed that there is no eSIM, do not despair.

• 📶 eSIM adapters → Nano-SIM: Companies like Airalo and Nomad sell physical devices SIM-cards with preloaded eSIM profiles, suitable for travel.
• 🔄 Double. SIM + Virtual Number: Use the primary physical number SIM and a virtual number (e.g., via Google Voice or Dingtone).
• 📱 Second phone: Some carriers (like Tele2) offer free eSIMs for tablets, and you can activate it on a second device and forward calls.

Be careful with eSIM → nano-SIM adapters from unknown manufacturers. Some of them may violate communication security or conflict with firmware. Before buying, check reviews on the 4PDA or XDA Developers forums.

If you are critically interested in eSIM support, consider upgrading to a newer model, for example, the POCO F5 Pro or Redmi Note 12 Pro+ 5G offer this feature at a price of 25,000 rubles (as of June 2026).

💡

Before buying a new eSIM phone, check with the operator for a list of supported devices, for example, MTS publishes it on the eSIM Settings page.

6. Frequent eSIM errors and myths in Poco X3 Pro

There's a lot of misinformation going around the web, and we're going to look at some of the most common misconceptions.

• 🔄 "After updating to MIUI 14 will be the eSIM" → Xiaomi didn't add eSIM support for older models through updates: Latest patches for Poco X3 Pro (MIUI 14.0.4) that's not fixed.
• 📡 "eSIM only works with the 5G" → It's not. Technology is not connected to the generation of the network. SE 2020 (no) 5G) supports eSIM.
• 🛠️ "You can turn on the eSIM through ADB" → There are instructions on activation via the adb shell on the network, but they either don't work or they can damage the firmware.
• 📦 "The Chinese version supports eSIM, but the global version does not" → All regional versions of Poco X3 Pro is deprived of this function.

Another popular myth is that if you have NFC on your phone, you have eSIM. It's not true -- the Poco X3 Pro is NFC-enabled, but virtual SIMs don't. These technologies are independent of each other.

7.The future of eSIM in Xiaomi: is it worth waiting for updates

With market trends in mind, eSIM will become the standard by 2026, with Apple fully switching to virtual SIMs in the iPhone 14 (for the US), and Samsung actively introducing the technology into the Galaxy S and Fold lineup. What about Xiaomi?

Analysis shows:

• 📈 All Xiaomi flagships from 2023 (starting with Xiaomi 13) support eSIM.
• 🔄 Budget segment: Redmi and POCO The feature appears selectively (e.g., Redmi Note 12 Pro).+ 5G, Not a Redmi Note 12. 4G).
• 🛠️ Updates for older models: Unlikely: Xiaomi focuses on new devices, and Poco X3 Pro has already been discontinued.

If you plan to use eSIM in the future, the Poco X3 Pro is not the best choice.The manufacturer clearly is not going to go back to older models to add this feature.

💡

By 2026, eSIM will become a mandatory feature for all smartphones in the EU (by the decision of the European Parliament), which could accelerate Xiaomi’s transition to virtual SIM, but older models like the Poco X3 Pro will remain without support.
