How to call Xiaomi for free: all ways

Owners of Xiaomi smartphones often wonder how to optimize communication costs, especially when it comes to frequent conversations with relatives or colleagues using the same ecosystem. Free calls within the network of one manufacturer is not a myth, but a real opportunity provided by modern VoIP technologies and specific settings of the MIUI or HyperOS operating system. Understanding the mechanisms of these functions allows you to significantly save on mobile operator tariffs.

There are several proven methods to make calls without taking minutes, from using the Internet protocol Wi-Fi Calling to transfer files via Mi Drop in older versions of firmware, each of which has its own characteristics, network quality requirements and configuration nuances that must be considered for stable communication.

In this article, we will take a look at all the options available, compare their effectiveness and answer frequent questions users have when trying to activate free communication. Technology is evolving rapidly, and what worked a year ago may require updating or replacing with more relevant solutions.

⚠️ Warning: Free calls are only possible if you have an active internet connection (Wi-Fi or mobile traffic.

Use of Wi-Fi Calling (VoWiFi)

The most reliable and native way to make free calls is Wi-Fi Calling technology, also known as VoWiFi. This feature allows your smartphone to use a wireless Wi-Fi network to transmit voice traffic, bypassing the standard cell phone towers. If your plan includes unlimited calls to inside numbers, then when you connect to your home Wi-Fi, you can call other Xiaomi numbers (and not only) without spending minutes of the main package, since the traffic goes through the Internet channel.

To activate this option, you need your mobile operator to support this technology. In Russia, most major providers have already implemented this feature. SIM-maps and mobile networks and select an active SIM card. There'll be a Wi-Fi call switch.

After turning on the status bar next to the signal level, a tube icon with the words Wi-Fi or HD will appear. Now, while in the wireless network coverage area, you can call for free if your tariff provides 1 at unlimited rates for mobile numbers. The quality of communication in this case depends on the Internet speed, not the signal level of the cell tower.

• 📶 The stability of the connection depends on the speed of your router.
• 💰 Minutes of the tariff plan are spent only if the caller is not in the Wi-Fi zone.
• 🌍 The function works even in roaming, allowing you to call home numbers as in the country.
• 🔋 Battery consumption when using Wi-Fi Calling is usually lower than when using a weak cellular signal.

💡

If the Wi-Fi Calling icon doesn’t appear, try restarting your smartphone or temporarily retracting and pasting it. SIM-re-frame after the function is turned on.

It is important to note that the terms remain standard for the call recipient: if they are within their network coverage, the call will also be free (incoming is usually free), and the technology is transparent to the user and does not require the installation of additional applications.

Calls through messengers and the Xiaomi ecosystem

The traditional way of communicating, which is often overlooked when looking for “native” solutions, is the use of instant messengers. While it is not a direct call through the phone book in the classical sense, integrating services into the MIUI shell makes this process as convenient as possible. You can use Google Duo (now Google Meet), Telegram, WhatsApp or Viber for video calls and audio calls.

But when it comes to Xiaomi-to-Xiaomi, it’s worth remembering the built-in services that the company previously offered, which used to be called Mi Drop, which in some versions allowed you to transfer files and initiate communication, but it didn’t become a full-fledged replacement for telephony, so the focus is on third-party but deeply integrated applications.

To optimize the process, you can set up widgets on your desktop or use the Quick Notes feature to quickly dial up contact, the main advantage of such calls is that they are completely free and do not depend on the operator's tariffs, consuming only Internet traffic.

Some users confuse free calls over the Internet with “No Limit to Xiaomi” rates. Telecom operators sometimes offer packages where calls within the brand network (or to certain numbers) are not charged. This is a marketing ploy of operators, not a function of the phone, but it is useful to know about such rates.

Analysis of tariffs of operators "Unlimited on Xiaomi"

Many users are looking for a way to call for free, implying special tariff options. Indeed, in the past, some operators (for example, Tele2, MTS, Beeline) launched the promotions “No Limit on Xiaomi” or “No Limit on social networks and messengers”, the essence of these proposals was that the traffic consumed when using certain applications or calls to numbers registered in the database of Xiaomi devices did not spend a basic package of gigabytes.

But it's important to understand the difference: unlimited traffic doesn't always mean free minutes. Often, operators have provided unlimited Internet for instant messengers, but voice minutes are charged separately, and most of these promotions are either closed or converted into shared minutes.

To check the current proposals, it is necessary to:

1. Open the official application of your operator.
2. Go to the "Fees" or "Services" section.
3. In the search, enter the word "Xiaomi" or "Unlimited".
4. Carefully examine the conditions: whether the option is for voice calls or only for the Internet.

⚠️ Attention: Tariff conditions change very quickly, information that was current a month ago may be incorrect today.

If an operator offers the option “Unlimited communication within the network”, it usually applies to all subscribers of this operator, not only owners of smartphones of a certain brand.

Comparison of free communication methods

To choose the best option for yourself, it is worth comparing the available methods by key parameters: quality, traffic consumption and operator dependence. Below is a table that will help to systematize the information.

And you can see from the table that Wi-Fi Calling is the most convenient native solution, because it's built into the dialing system. You don't have to open a separate application, you just dial the contact number as usual, while messengers give you more independence from cell towers.

For users who are often in places with poor cellular signal (basements, country houses), the combination of Wi-Fi Calling and instant messengers is perfect. Xiaomi smartphones do a great job of switching between networks, ensuring continuity of conversation.

💡

The optimal strategy is to use Wi-Fi Calling as the main method of home and office, and instant messengers as a backup channel in the absence of VoWiFi support by the operator.

Setup and troubleshooting

Even when set up correctly, there can be problems. Often users will experience the feature not activating or the call is disrupted. The first step should always be to check for system updates. Go to Settings → About Phone → MIUI version and press the update button.

If the problem persists, try resetting your network settings. This won't delete your personal data, but will return the connection settings to factory values. → Connection and sharing → Reset Wi-Fi, mobile networks and Bluetooth.

It's also worth checking if the firewall or antivirus is blocking voice traffic.The built-in MIUI Security protector can sometimes aggressively limit the background activity of call apps.

In rare cases, the problem may be on the operator's side, call support and check if VoLTE/VoWiFi is activated on your number, sometimes requiring re-registration of the service in their database.

Security and confidentiality of calls

When it comes to free calls, security is not an issue to ignore. Wi-Fi data protocols can be vulnerable if you use open public networks. Encryption in modern messengers (End-to-End) provides a high level of protection, but native Wi-Fi Calling relies on the security of the operator's network and the Wi-Fi router.

When using public access points (cafes, airports), it is recommended to avoid transmitting sensitive information during conversations over Wi-Fi, if you are not sure about the security of the channel. 4G/5G.

Xiaomi is implementing various layers of protection into its operating system, including app isolation and permission control.

Remember that free calls through Internet applications often leave metadata on the servers of these applications, while the carrier sees only the fact of the connection to the Internet, but not the content of the conversation (when using encryption).

Frequently Asked Questions (FAQ)

Critical:

For Wi-Fi Calling to work, support must not only be from the phone and operator, but a specific router model must not block the corresponding ports, although this is extremely rare at home.
