Owning a modern Xiaomi smartphone means constant access to the network, and for residents of the peninsula, Win Mobile often becomes the main provider of digital services. However, the automatic network configuration does not always work correctly, especially on devices with a MIUI shell or a new HyperOS, which requires manual user intervention. The lack of Internet can be caused by many factors, from a banal lack of funds to complex conflicts in the profile of the APN access point.
In this article, we will discuss in detail the process of manual settings to ensure a stable 4G/LTE connection. You will learn how to enter data correctly, where to turn for help if standard methods do not work, and what hidden settings can block data transfer. For the correct operation of 4G in Crimea on Xiaomi, it is critical to manually prescribe an APN with the name "internet" and IPv4/IPv6 protocol.
We will consider not only the standard path through the settings menu, but also the specific features of the work. SIM-Understanding the principles of network protocols will help you avoid common mistakes. Let's move on to practical steps to troubleshoot problems.
Preparation of SIM-card and verification of network coverage
Before you go into the complex menu settings, you need to make sure that the components are physically healthy and the status of the service. Often the problem is not a software failure, but that the system is not a software failure. SIM-The card is not activated for data transmission or has damage to the contact platform. Make sure that there are funds on the balance, since at zero balance, the operator can block access to the network, leaving only incoming calls.
It is important to check whether your Xiaomi supports the required frequencies. 3G and 4G, If the phone is forced to set the mode "Only" 4G" In the area of poor reception, the Internet will not work, it is recommended to temporarily switch to mode "3G/2G (auto” to check if a data transmission icon appears.
- 📡 Make sure that the mobile internet slider in the notification curtain is activated and lit in blue.
- 💳 Extract. SIM-card, wipe the contacts with a soft cloth and paste back until the characteristic click of the tray.
- 📶 Check the signal level: for stable 4G needlessly 2-3 network-scale.
- 🔄 Restart the device so that it registers again at the operator’s base station.
⚠️ Note: If after resetting the icon 4G/LTE It doesn’t even appear with a full signal scale, maybe, SIM-The card is too old and does not support standards. LTE. In this case, it is necessary to replace SIM-map-board.
It is also worth considering that some tariff plans require a separate connection of the Internet access service. Even with money in the account, without an activated traffic packet, the network can not let you into the world wide web. USSD-command or personal application of the operator.
Manually configure APN access point on Xiaomi
The most effective way to solve the problem is to manually create a new access point. Automatic settings that come in SMS often contain errors or are incompatible with the version of Android installed on your Redmi or Poco. You will need to create a new profile with the exact parameters provided by the operator Win Mobile.
To start, go to the settings menu. The path may vary slightly depending on the shell version, but the logic remains the same. You need to find the section for SIM cards and mobile networks, and here are the key parameters that control the connection.
In the menu that opens, select SIM-the card you plan to access the network (if there are two (APN)". Click the New Access Point button or the plus icon in the upper right corner of the screen. Now you will see a form that you need to fill in the data from the table below.
| Parameter | Importance for Win Mobile | Note |
|---|---|---|
| Name (Name) | Win Mobile Internet | Any name for convenience |
| Access Point (APN) | internet | Register is important, write in lowercase |
| User name | (leave empty) | Don't fill in |
| Password. | (leave empty) | Don't fill in |
| Type APN | default,supl | Or choose from the "default" list. |
| Protocol APN | IPv4/IPv6 | Recommended option |
Once you have entered all the data, be sure to click the menu (three dots or the "More" button) and select "Save." Then go back to the list of access points and activate the profile you just created by ticking next to it. Without this step, the settings will not take effect.
☑️ Checking settings APN
Configure network types and preferred mode
Even with the right APN settings, the Internet may not work if the phone menu selects the wrong type of network. The MIUI shell allows you to flexibly manage this setting, but sometimes the system itself switches to modes that are not supported by the operator in your location.
In the same menu where you set up APN, look for "Preferred Network Type" and don't choose "4G Only" as this can lead to loss of connectivity in areas of unstable coverage. The best option is a combined mode that allows the phone to switch between standards.
If you are in a confident reception zone but the speed remains low, try forcefully switching to 3G and then returning back to 4G. This action initiates a reconnection to another base station, which often solves the problem of "sticking" at low speed.
- 📶 Select the "Preferred" mode 4G (LTE)" for maximum speed in cities.
- 📉 Use it "3G (WCDMA)", If you are in a rural area or inside buildings with thick walls.
- ✈️ Regime “Only” GSM" Use only in extreme cases where only voice communication is needed.
💡
If the internet is slow, try using the APN settings in the Authentication Type field to select PAP or CHAP, although the value “Not specified” is usually appropriate.
It is worth noting that some global versions of Xiaomi may hide the choice of network type in the standard menu, in which case you may need to enter special code in the engineering menu or use applications to change the region, but this is rarely required to work with Win Mobile.
Solving problems with dual-symbol devices
Smartphone owners with two SIM-These cards often face conflicts when the Internet "goes" to the second card or stops working at all. MIUI allow you to assign a card to transfer data by default, but this mechanism sometimes fails after an update or change SIM-map.
Go to the settings. SIM-And make sure that the Internet or Mobile data selects the exact SIM that Win Mobile is configured on. If you have two SIMs of the same operator, the system may confuse their IDs, so it's better to temporarily disable the second card to check.
⚠️ Attention: When using two SIM-cards of different operators (for example, Win Mobile and MTS / Beeline), make sure that data roaming is turned off for the second card, so as not to spend funds unexpectedly.
Also check your traffic savings settings. MIUI has Traffic Savings, which can block background data transfers for some applications or even the entire system if a hard limit is activated. Turn off limits or add necessary applications to exceptions.
If the problem persists, try changing slots. SIM-On some models, the first slot has priority over speed or support for certain frequencies, although this is less common in modern devices.
What if the internet is only available in Wi-Fi?
Reset network settings and additional commands
When manual adjustment fails, a radical but effective method is to reset the network settings, which will return all mobile, Wi-Fi and Bluetooth settings to factory values by removing possible configuration software errors.
To perform the reset, go along the path: Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth. Confirm the action and wait for the device to restart. After that, you will have to re-enter the passwords from Wi-Fi networks, but the APN settings for Win Mobile will have to be reset according to the instructions above.
There is also a secret code to check IMEI and network status that can be useful in diagnosing: Enter the dialer code ##4636##. In the menu that opens, select Phone Information. Here you can see the connection status and force the network type to be set if the standard menu doesn't provide the right options.
The code for entering the test menu: ##4636##In this menu, look for the line "Tune your preferred network type." Select an option that contains LTE (e.g. LTE/TD-SCDMA/GSM). Don't choose "NR" options if your region is not already covered by 5G networks, as this can lead to constant network searches and battery drain.
💡
Network reset eliminates 90% of software connection errors, but requires re-authorization on all Wi-Fi networks.
