Modern Xiaomi, Redmi and POCO smartphones allow you to stay connected anywhere in the world, but not all users understand how the connection mechanism works outside the home network. Roaming is the technical ability of your device to register with other carriers when you are out of coverage of your provider. Without activation of this feature, the phone simply will not catch a signal when you are in another country or even in a remote region of your country.
Many tech owners are afraid of accidental charges, so they often ignore the communication settings completely, depriving themselves of the ability to take important calls or use the Internet on a trip. Understanding how the MIUI or HyperOS operating system manages switching between the towers of different operators will help you feel more confident in traveling. In this article, we will discuss all the nuances of this technology, types of connections and ways to control costs.
Principle of operation and types of roaming on Xiaomi devices
When you travel outside your home coverage area, your Xiaomi smartphone starts scanning the airwaves for available networks. International roaming allows the device to connect to an affiliate operator in another country, ensuring continuity of communication. It is a complex process of agreeing protocols between your home provider and a foreign network that happens automatically when you have permission in your settings.
There is also intranet or national roaming, which is relevant for countries with a large area where one operator does not cover the entire area, in which case the phone switches to the network of another operator within the same country, which is often perceived by the user as a normal communication signal.
It is important to distinguish between voice roaming and data roaming, as the charging of these services can differ significantly. SMS It's usually more expensive, but more predictable, whereas Internet traffic can be consumed very quickly in the absence of limits. MIUI Provides flexible tools to manage each of these types of connections separately.
💡
Always check your operator’s fares before traveling, as roaming conditions may vary from provider to provider, even for the same country.
Where to find roaming settings in the MIUI and HyperOS menu
Shell interface MIUI And the new HyperOS may be slightly different depending on the Android version, but the settings logic remains the same. To access network management, you need to go to Settings, then select the item. SIM-Maps and mobile networks. This is where all the key switches that make your Xiaomi interact with the outside world are located.
Once you select a particular SIM card (if there are two), you will see a detailed menu where you need to find the data roaming option. In some versions of the firmware, this item may be simply called "Roaming" or hidden in the submenu "Mobile Network." Activation of the slider allows the system to register on other networks, but does not always mean automatic Internet activation.
If you can't find the right switch, search by settings by typing the word "roaming" into the search bar at the top of the screen. This is a universal way for all models, whether it's a budget Redmi or a top-end Xiaomi 14. The system will immediately redirect you to the desired section, eliminating human factor and navigation errors.

Differences between voice roaming and data transfer
Users often confuse the ability to call and the ability to use the Internet, although technically they are different channels. Voice roaming is activated automatically when you register with a partner's network, and you can take incoming calls (often free or on a special tariff) and make outgoing ones. Data transfer requires separate confirmation, since it generates the most costs.
On Xiaomi smartphones, you can customize usage scenarios: for example, allow data roaming for only one SIM card, leaving the second only for calls. This is especially true for models with two physical slots or eSIM support. Traffic separation helps control budget and avoid situations where background applications start downloading updates through an expensive overseas network.
It is worth noting that modern messengers (WhatsApp, Telegram, Viber) work exclusively over the Internet. If you have data roaming enabled, they will function as usual, but if only voice – messages will come only after connecting to Wi-Fi. Understanding this difference is critical for those who depend on operational communication on business trips.

How to Avoid Excessive Travel Costs
The most effective way to protect your budget is to pre-examine your operator’s fares and set limits on the device itself. Xiaomi’s Traffic Limits feature allows you to set a strict limit on the amount of data transferred per month or on a trip, and when you reach the threshold, the system will automatically turn off mobile Internet, saving money in your account.
The second important aspect is the management of application background activity. Many programs, such as Google Photos, Dropbox or cloud storage, can start syncing immediately when the network appears, and it is recommended to go to the application settings before traveling and prevent them from accessing mobile data in roaming, leaving access only via Wi-Fi.
It's also useful to use the Traffic Savings mode built into MIUI, which restricts data transfer in the background to all applications except those you've explicitly authorized, and it's not a panacea, but an additional forgetfulness insurance that works at the operating system level.
Comparison of roaming costs among major operators
The tariff policy of mobile operators varies greatly, and choosing a provider before traveling can save a significant amount. Below is a comparative table of conditions for popular packages relevant to users of Xiaomi equipment in popular tourist destinations.
Note that prices can change and it is always worth checking the current information on the operator’s website. However, the general trend is that package offers for travelers are more profitable than minute-by-minute fares. Redmi and POCO smartphones work perfectly with all communication standards (GSM, 3G, 4G, 5G), so the choice depends only on coverage and price.
| Operator. | Package type | Price per day (approximately) | Included. |
|---|---|---|---|
| Operator A | Unlimited Internet | 299 rubles. | Traffic, social media. |
| Operator B. | Package of minutes and GB | 199 rubles. | 100MB, 5 min |
| Operator B | Hourly pay | 50 rubles/hour | Traffic without limit |
| Operator G | Tourist | 350 rubles. | 1GB, 10 mins, SMS |
💡
Package offers ("daily packages") are almost always more profitable than standard charging on the fact of use, even if you only need the Internet for a couple of hours.
Connection problems and their solution
Sometimes it happens that the roaming slider is turned on, but the network does not appear. The first thing you try to reboot the Xiaomi smartphone is a classic tip that in 80% of cases solves the problem of registering in a new network. Android operating system should re-initiate the search for available towers and conduct handshake with the operator.
If the reboot didn't work, check if the network selection limit is worth it. → SIM-maps and mobile networks → Try switching from Auto to Manual, waiting for the list of available operators, and manually selecting the right one. Sometimes automatic selection gets stuck on a weak signal or incompatible frequency.
Also make sure that the roaming service is activated on the side of your operator, this can be done through the operator's application, personal account or USSD-Without this service, settings in a Redmi or Xiaomi phone will be useless, as the network will simply reject the registration request.
⚠️ Note: If you are in a sanctions conflict zone or remote region, your home carrier may not have a partnership with local providers, in which case the phone will show “No Network” regardless of settings.
Using eSIM for international roaming
Xiaomi’s current flagships are increasingly supporting eSIM technology, which allows virtual SIM cards to be connected without physical replacement, a revolutionary solution for travelers to buy a local operator’s fare before they leave home.
To configure eSIM, you need to scan. QR-code provided by the operator in the Settings section → SIM-maps and mobile networks → Add the eSIM tariff. Once activated, you can rename the profile, for example, to "Travel Data", and assign it to the preferred data transfer, leaving the main SIM card only for calls.
The advantage of using eSIM on MIUI is that you can instantly switch between profiles. You can have multiple tariffs from different countries and activate the one you want with a single touch. This makes Xiaomi’s smartphone a versatile tool for global travel, eliminating the need to carry a pack of plastic cards.
⚠️ Note: When resetting your phone to factory eSIM profiles may be deleted. be sure to back up or save QR-Operator codes before device formatting.
