How to connect roaming on Xiaomi: a step-by-step guide

Traveling to another country is always a vivid experience, but for owners of Xiaomi, Redmi and Poco smartphones, it can be a real test if you do not take care of the connection in advance. Modern shells MIUI and HyperOS have many hidden settings that can block the Internet from working outside the home network, even if the service is paid for by the operator. Many users face a situation where the SIM card sees the network, but there is no data transfer, which makes it impossible to use a navigator or messengers.

In this article, we will take a look at all the steps in preparing your device for international roaming, not only the standard menu switches, but also the specific settings of APN access points, which often require manual adjustments, and the proper setting will help to avoid unnecessary costs and ensure a stable connection anywhere in the world.

Before you go to the airport, you need to perform a number of preparatory steps that are often ignored. Roaming is a complex service, depending on the interaction of your device, the operator’s settings and the chosen tariff plan. Simply including a slider in the menu may not be enough to properly work modern 4G and 5G networks.

Preliminary preparation and tariff verification

The very first step to take long before you cross the border is to contact your mobile operator. Unlike the internal settings of the phone, the ability to work abroad depends solely on the terms of your contract.

Often, operators default to blocking access to the network abroad for security reasons to avoid space accounts. You need to explicitly request support permission to use data roaming, without this step, even a perfectly configured smartphone will not be able to access the Internet.

⚠️ Before traveling, be sure to check the cost of one megabyte of traffic without connecting a special package. In some exotic countries, the price can reach several hundred rubles per megabyte, which will lead to the instant loss of a large amount of money.

It’s also worth checking if your SIM card supports modern communication standards, and if you’re using a very old SIM card that’s been released more than 10 years ago, it may not work properly on 4G/LTE networks abroad, so it’s recommended to replace the card with a new one that supports USIM in the carrier’s cabin before traveling.

Remember to record your operator’s support number in the format available for calls from abroad (usually a +7 number or a special short number for roaming subscribers) this will help you quickly resolve problems with blocking or setting up services while staying at the hotel.

Basic data transfer settings for Xiaomi

Once the service is activated from the operator, we move on to the settings of the smartphone itself. MIUI interface may vary depending on the version, but the logic remains the same. You need to get into the SIM card settings menu, where the parameters of the mobile network are adjusted.

• 📱 Open the Settings app and go to the section «SIM-maps and mobile networks».
• 🌍 Select the SIM card you plan to use for the internet (if there are two, make sure you choose the right one).
• 🔓 Find the Data Roaming Switch and activate it by confirming the system warning.
• 📶 Make sure that the "Network Type" section selects the "Preferred" preference. LTE» or «5G».

Activation of the data roaming item is critical. Without this permission, the Android operating system blocks any exchange of data packets through foreign towers, even if the network signal is present.

In some cases, automatic network selection may not work properly, especially in border areas or countries with complex infrastructure. If the phone is constantly switching between operators or losing signal, try manually selecting the available network from the list of available ones. This often stabilizes the connection.

It is worth noting that on two-symbol Xiaomi devices, the settings apply separately for each card. If you use one SIM card for calls and a second (local or tourist) for the Internet, make sure that the default data settings select the card you want to spend traffic on.

Manually configuring APN access points

The most common reason for the lack of Internet when roaming is incorrect configuration of the access point APN (Access Point Name), the smartphone can automatically tighten old or incorrect settings that do not work on a foreign network, in such cases, manual intervention is required.

To enter the settings menu, go on the Settings path → SIM-maps and mobile networks → (Your SIM card) → Access points (APN). Here you'll see a list of existing profiles. If the Internet doesn't work, it's best to create a new hotspot from scratch to avoid conflicts with the stored data.

When you create a new access point, you will need to enter the data that your operator provides. Usually, you just need to specify a name (any, for example, "Internet") and enter an address in the APN field (for example, "internet.mts.ru" or "internet.beeline.ru"). The remaining fields, such as username and password, are often left blank or also taken from the operator's instructions.

Once you have entered all the data, be sure to click the “More” button (three dots in the corner) and select “Save.” Then remember to activate the created profile by ticking next to it. Without saving and activating the new profile, the changes will not take effect, and the phone will continue to use the non-working settings.

⚠️ Attention: When manually adjusted APN Check the letter register carefully and there are no extra spaces. Proxy and Port fields should not have any values unless the operator explicitly indicated that they are necessary.

Solving problems with registration on the network

Even with the right settings, there can be situations where the phone sees the network but doesn't register, which is often the first time you turn on a device in a new country, and the first thing you do is try to reboot your smartphone, which forces the communication module to re-enter the search and authorization process.

If the reboot didn't work, check if the Flight mode is on. Sometimes the system can freeze when the radio module is formally on but not functioning. Turn on the flight mode for 10 seconds, and then turn it off. This will force all the radio interfaces of the device to restart.

In rare cases, the problem lies in the choice of a network standard. 4G/LTE or it works on frequencies that your Xiaomi doesn’t accept well, try switching the network type in the settings on “Only” 3G» or «3G/2G». This will slow down the speed, but it can save the situation with connectivity.

It’s also worth considering that some Chinese versions of Xiaomi smartphones may have a stripped-down set of supported frequencies (Band).If you’re in a region where the main carrier uses a rare frequency (for example, the Band 20 in Europe or specific bands in the US), the phone may simply not see the network, in which case only a change of operator or using an external modem will help.

Using eSIM for Travel

Xiaomi’s current flagships support eSIM technology, which is a great solution for travelers. Instead of buying a physical SIM card at the airport or setting up an expensive roaming home operator, you can set up a virtual profile of a local operator or global data provider.

This allows you to keep your primary number active for important calls and SMS (Bank codes), and use the Internet through a cheap local tariff. eSIM is set up by scanning QR-code provided by the operator through the Settings menu → SIM-maps and mobile networks → Add eSIM.

The main advantage of eSIM on MIUI is the flexibility of the control, you can switch at any time which of the SIM cards (physical or virtual) is used for data transfer without removing any plastic cards, which is especially convenient for frequent business trips.

💡

When using eSIM, be sure to enable the “Allow Mobile Data Switching” option in the SIM card settings, which will allow the phone to automatically use the main SIM card for the Internet if the eSIM loses the signal, and vice versa, ensuring continuity of connection.

However, it is worth remembering that not all operators support eSIM, and in some countries this technology may be limited by law.Be sure that the provider you choose works with virtual cards in a particular region before buying a tariff.

Safety and traffic saving

While roaming, it's important not only to set up a connection, but also to secure your data. Open Wi-Fi networks in hotels and airports pose a serious threat. Use a VPN to encrypt traffic, especially if you need to log into banking applications or work with corporate mail.

To save traffic and money, set the limits in the phone itself. In the Data Transfer section, set the monthly limit corresponding to your package and turn on a warning to reach the 80% and 100% limit.

• 🚫 Turn off autoplay video on social networks and instant messengers.
• 📸 Ban cloud services (Google Photos, Yandex Drive) synchronization via mobile network.
• 📲 Set a Traffic Saving mode for heavy apps to limit background activity.
• 🌐 Use “Lite” mode in your browser or apps if the network speed is low.

It is also recommended to disable app updates via mobile in the Google Play Market and App Store settings. Update programs only over Wi-Fi at the hotel so as not to accidentally spend the entire gigabyte package downloading a heavy game or a navigator map.

⚠️ Note: In some countries (e.g. China, UAE) use VPN It may be restricted or prohibited by local law, and you should check the laws of your host country in advance to avoid problems with the law when trying to bypass the locks.
