Mi Roaming on Xiaomi: The Complete Guide to Setup and Disable

If you own a Xiaomi smartphone, you’ve probably encountered a mysterious Mi Roaming feature in your mobile network settings, which often raises questions about what it does, why it sometimes appears without your knowledge, and how it affects traffic consumption. Unlike standard roaming, which is activated when traveling abroad, Mi Roaming works differently — and it’s not always obvious what its benefits are.

In this article, we will take a closer look at what Mi Roaming is on Xiaomi, how it differs from regular roaming, when it should be used and when it should be turned off. You will also find step-by-step instructions for setting up for different models (including Redmi, POCO We will focus on the hidden nuances, for example, why the feature can automatically connect to foreign networks even in the home region, and how to prevent this from happening.

What is Mi Roaming and how is it different from regular roaming?

Mi Roaming is Xiaomi’s proprietary technology that optimizes mobile connectivity in low-signal conditions or when moving between carrier coverage areas. Unlike classic roaming (when a phone connects to a partner operator’s network abroad), Mi Roaming works both in the home region and beyond.

The main differences:

• 🌍 Geography of work: classic roaming is activated only abroad, and Mi Roaming can also work in the home country (for example, in border areas or with a weak signal from the main operator).
• 📶 Auto-switching: The feature selects the most stable network, even if it belongs to another operator (but only among Xiaomi partners).
• 💰 Tariffing: in most cases, Mi Roaming does not entail additional payments, but there are exceptions (more about this below).
• 🔄 Setting flexibility: you can manually enable/disable the function or set the conditions for its activation.

It is important to understand that Mi Roaming is not a separate service operator, but a software solution from Xiaomi.It works on top of standard mobile network settings and can interact with the mobile network. SIM-maps of most Russian and foreign operators (but not all of them – more about this in the next section).

How Mi Roaming Works: Technical Details

Mi Roaming technology is based on dynamic network selection, taking into account several parameters:

• 📊 Signal strength: if the main operator's signal strength falls below a threshold (usually -105 dBm, the phone starts scanning the available partner networks.
• 🔗 List of trusted operators: Xiaomi enters into agreements with local providers whose networks can be used for roaming without additional user approvals.
• 📡 Network priority: The algorithm prefers networks with better bandwidth (e.g, 4G/LTE instead 3G), Even if they belong to another operator.
• 🔄 Backup mode: If the main network is not available (for example, in case of an accident at the operator), Mi Roaming automatically connects to the backup.

The switching process takes 5 to 30 seconds and is accompanied by a short-term connection break, at which time a notification “Connect to the network...” or “Roaming: [operator name]” may appear on the screen. It is important that Mi Roaming does not always use international roaming – often it connects to local partners, which is cheaper for the user.

But there are pitfalls:

⚠️ Note: If your carrier does not support Mi Roaming or does not have a partnership agreement with Xiaomi, the phone can connect to a foreign network with high tariffs. For example, in the border regions of Russia (for example, in the Kaliningrad region), the smartphone can “clunge” to the Polish or Lithuanian network, which will lead to unexpected costs.

What operators are compatible with Mi Roaming in 2026?

The list of operators supporting Mi Roaming depends on the region and smartphone model, and the table below shows the current list for Russia, CIS countries and popular tourist destinations (data for June 2026).

If your carrier isn't on the list, it doesn't mean Mi Roaming won't work. The smartphone can connect to the partner's network, but:

• 💳 Additional payments are possible (especially abroad).
• 📵 The quality of the communication may be worse than that of the main operator.
• ⚙️ At some tariffs, the function is blocked by the operator (for example, on the "minimal" from Tele2).

To avoid unpleasant surprises, check your operator's roaming conditions before traveling. For example, MTS has a special "Travel" rate, which includes a free Mi Roaming at 100.+ country.

1. Background Updates: When connected to a new network, the phone can automatically update applications, sync data, or download geolocation databases.
2. Switching between networks: Each time you change the operator, you re-authenticate, which consumes up to 5-10 MB of traffic.
3. Tariffing errors: Some operators consider roaming traffic to be overpriced, even if it is a local network.

How to prevent traffic from flowing:

• 🛑 Turn off auto updates: go to Settings → Annexes → Auto Update and select "Only over Wi-Fi".
• 📴 Use In-Air mode in the unstable signal zone to avoid constant reconnection.
• 📊 Set a traffic limit: in Settings → SIM-map → Data limit set a threshold (e.g. 500MB/day).
• 🔄 Manually select the network: in Settings → Mobile network → Select the network to disable "Automatically" and select your operator.

⚠️ Note: If you notice that traffic is going away even when Mi Roaming is turned off, check your settings. APN. Some firmware (especially custom ones) can use gray routes to transfer data, bypassing operator restrictions. → System system → Reset → Resetting network settings.

💡
