Use of the SIM-Xiaomi often requires manual configuration of network settings, especially if the automatic sending of settings did not work or the device was purchased abroad. APN Mobile Internet will not work even if there is a signal and a positive balance, which is common for users who switch from other operators or change their tariff plan.
In this guide, we will discuss in detail the process of creating a new connection profile, specify the exact values for all fields and consider typical errors that occur on the shell. MIUI Or HyperOS. You'll learn how to switch network mode to 4G, check out SIM-maps and restore access to the World Wide Web in a few minutes, and the right setup is the key to stable speed and no problems with the Internet. MMS or sending messages.
Before you start changing system parameters, make sure your SIM-The card is activated and pasted into the correct slot. In modern Xiaomi models, it is preferable to use the first card slot with the Internet to avoid confusion when choosing a data source.
Preparation of SIM-card and checking the network status
The first step is to physically install the map and basic visibility check by the system. SIM-LUGAKOM card in a slot compatible with 4G (It's usually marked with an appropriate icon or indicated in the model instructions. After you turn on your smartphone, pay attention to the top panel: if you see the icon, 4G or LTE, But the Internet does not work, the problem lies in the settings of the access point.
If the network icon is not at all, it is possible that the card is not read or blocked. PIN-In this case, the system will request unlocking as soon as it boots. PIN-code, otherwise three false attempts will require PUK-code that can be found on a plastic card or in a personal account.

- 📱 Make sure the switch is “Use”. SIM-The map is active and lit in blue.
- 🌐 In the "Network Type" option, select the preferred option, for example, Preferred 4G (LTE).
- 🔒 Check the status of roaming: if you are in the coverage area of the home region, roaming can be turned off, but for correct registration in the network it is sometimes useful to briefly turn it on and off.
It is important to note that only one mobile internet access point can be active on two-symbol Xiaomi devices at a time. If you use a second card for calls, make sure that the mobile internet section is selected. SIM-map.
Step-by-step instructions for creating an APN access point
The main stage of setting up is to manually enter the APN (Access Point Name) protocol settings, which is the data that tells your phone which gateway to access the network. On Xiaomi smartphones, this section is hidden slightly deeper than in pure Android.
Enter the Settings menu → SIM-maps and mobile networks. Choose yours. SIM-map LUGACOM and find the access point (APN). The list that opens will probably already have some notes or one blank.
☑️ Pre-entry check APN
Press the New Access Point button or the plus icon in the lower or upper right corner of the screen (location depends on the version of MIUI). A form with many fields will open. Most of them can be left blank, but the key parameters must be filled in precisely, with a register of letters.
Fill the fields with the following values:
| Parameter | Meaning | Note |
|---|---|---|
| Name. | Lugacom Internet | Any convenient name |
| APN | internet.lugacom.ru | Definitely lowercase, no spaces |
| User name | (empty) | Leave empty |
| Password. | (empty) | Leave empty |
| Type APN | default,supl | Or just a default. |
Pay special attention to the APN field. It should not have any unnecessary spaces at the beginning or end of the line. Often users make the mistake of copying the address from the clipboard along with an invisible symbol, which leads to the failure of the connection. The protocol should be listed as IPv4/IPv6 if there is such a choice, although the default is usually the car.
⚠️ Warning: After you have entered all the data, be sure to click the "More" button (three dots in the corner) and select "Save." If you just go back, the new access point will not apply.
Once saved, go back to the list of access points and make sure that the profile you created is marked with a green tick or selection marker. If there is no tick, click on the profile name to activate it manually.
Configuring network types and modes of operation
Even with properly entered APN, the Internet may not work if the phone tries to use outdated communication standards or, conversely, clings to weak 4G where 3G would work better.
Same menu. SIM-If you're looking at the map, you can find "Network Type" or "Preferred Network Type" and you can find a few options here. 4G (LTE).

Solving Data Transfer and MMS Problems
A common problem for Xiaomi users is that the Internet works in the browser, but does not pass MMS or update widgets. This is due to aggressive energy savings and the peculiarities of the background processes in the MIUI shell.
Check your network access settings for important applications. Go to Settings → Apps → All apps, find the right one (like Messages or Messenger) and select Other Permits or Network Access. Make sure you tick Mobile Network and Wi-Fi.

- 📩 Make sure you're on the profile. APN in the field "Typical" APN» Added the value of mms by comma (e.g.: default,supl,mms).
- 🚫 Turn off Traffic Savings mode in the notification curtain if it’s active – it can block background media loading.
- 🔄 Restart the device after making changes to the MMS-parameters to be applied at the modem level.
If MMS still don't go, check the balance. MMS service can be charged separately or require packet traffic. Also make sure that the date and time settings are automatically determined, as the wrong time disrupts the secure connection.
Diagnostics and elimination of connection errors

Frequent questions and additional recommendations
To finish the setup, it is worth mentioning the impact of the firmware version. On global versions of MIUI, the settings may differ from those in Chinese. If you have a Chinese version (CN) and you use a Russifier, some menu items may be called differently or hidden, in which case you should use a search by settings, typing the word "APN" or "Point".
Remember to check system updates periodically. Operators often change gateway settings, and newer versions of Xiaomi firmware already contain current profiles for automatic configuration.
💡
The most common mistake is a blank at the end of an APN address or not saving a profile before leaving the menu. Always check for a green check box.
If you are using a router or giving out internet from your phone, make sure that the APN profile in the Type APN field indicates default,supl,dun.Adding the dun option allows the phone to be used as a modem, which some operators block at certain rates, but for LUGACOM this usually works as standard.
Remember, the quality of communication depends not only on the settings of the phone, but also on the loading of the tower. During peak hours, the speed can drop regardless of the correct parameters entered, in which case waiting or moving to another point helps.
