Owners of budget smartphones often face the need to quickly configure access to the global network, especially after buying a new device or changing the operator. The Xiaomi Redmi 8, despite its availability, features a modern communication module that requires the right configuration for stable operation. SIM-card or moved to a different coverage area, the system may not activate the data transmission automatically.
Lack of network connectivity limits the functionality of the gadget, turning it into a simple “caller” without access to instant messengers, navigation and online services. In this article, we will examine in detail all possible ways to activate the Internet, from elementary switches in the notification curtain to manually registering the parameters of the APN hotspot. You will learn how to diagnose a problem if the mobile Internet slider burns, but the pages do not load.
We'll look at the nuances of how the MIUI shell on Redmi 8 works, because it has its own traffic management and application permissions, and understanding these mechanisms will help you avoid situations where the Internet is lost due to power saving or background data limitations. Let's start tweaking your device Step-by-step.
Basic activation via notification panel and menu
The fastest way to start surfing the web is to use standard interface tools. Xiaomi Redmi 8 owners don't have to dive into deep system settings every time. Just swipe down from the top of the screen to open the notification curtain, and there are fast switches, among which we are interested in the icon with two arrows or antenna symbol.
If the Mobile Data icon is inactive (grey), click on it once, it should be illuminated in blue or green, indicating that the module is activated. In the upper right screen, next to the battery indicator, the letters 4G, H+ or G should appear, indicating the type of current connection. The absence of these symbols indicates that the Internet is on the system, but no contact is established with the operator tower.
⚠️ Note: If after the slider is turned on, the icon 4G It appeared, but through 10-15 The second you’ve lost and changed to an “E” or “G”, this may indicate a weak signal in your location or problems with your balance.
The alternative route is through the main settings menu. You need to find the Settings section. → SIM-And maps and mobile networks, and you can choose from them. SIM-You can use a card to access the Internet if you have two of them on your device. Make sure that the "Use mobile data" switch is in the active position. It also displays traffic statistics, which is useful for controlling costs.
- 📱 Check if the indicator is on. 4G/LTE status bar after inclusion.
- 🔄 Try to put your phone in flight mode for 5 seconds and turn it off to restart the communication module.
- 💳 Make sure that SIM-The card is defined by the system and displayed in the list of active.
Setting up an APN access point for mobile operators
Often, all switches are active, but the Internet is not working. 90% of the time on Xiaomi smartphones, this is solved by manually adjusting the access point. APN (Access Point Name: Telecom operators (MTS, Beeline, MegaFon, Tele2) Usually send automatic settings. SMS-message, but in case of failures or use of corporate tariffs, you have to enter data manually.
To enter the configuration menu, go to Settings path → SIM-maps and mobile networks → Choose yours. SIM-map → Access points (APN). In the list that opens, you'll see current profiles. To create a new one, click on the plus in the lower right corner or select "New AP." Here, it's critical to enter data without errors, observing the register of letters.
Name: MTS Internet (example)
APN: internet.mts.ru
User name: mts
Password: mts
Type of authentication: PAP or CHAP
Type APN: default,suplOnce you have entered all the options, 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 check the box against the profile you created. Rebooting the phone after this procedure is mandatory for the changes to be applied. If the settings are correct, the Internet will work instantly after the screen is turned on.

Diagnostics problems with Wi-Fi connection
Wireless Wi-Fi on Redmi 8 operates at 2.4 GHz and 5 GHz. Connection problems often arise due to conflict IP-addresses or static settings DNS. If the phone sees the network but says "Connected, no Internet access," the first thing you should do is try to forget the network. To do this, click on the name of your network in the list of available and select "Delete" or "Forget».
Then reconnect by re-entering the password. If that doesn't work, change the IP settings from "Static" to "DHCP" (or vice versa if DHCP doesn't give you an address), this is done in advanced Wi-Fi settings when you connect: click on the arrow or gear next to the network name, find "IP settings" and select the option you want.
Another common cause is a router malfunction or overflow of memory, in which case no phone settings will help until the router is restarted. MAC-address, which often occurs in offices or public places.
- 📡 Make sure the date and time on the phone are set correctly – a time error blocks secure connections.
- 🔒 Check the type of network security (WPA2/WPA3) — Older protocols may not be supported by new security settings MIUI.
- 📶 Try connecting to another phone’s hotspot to prevent Wi-Fi module failure in the Redmi 8 itself.

Resetting network settings and rebooting modules
When software failures accumulate, the standard shutdown and slider turn on stops helping. In such cases, Xiaomi Redmi 8 effectively runs a full reset network settings. This operation will not delete your contacts, photos or applications, but return all connection parameters (Wi-Fi, Bluetooth, mobile networks) to factory state.
You can reset via the Settings menu → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth. The system will warn you that saved passwords from Wi-Fi will be deleted.

Features of the two SIM-maps on Redmi 8
The Redmi 8 model supports two SIM-This is a common cause of confusion. → SIM-There's a separate "Default for mobile Internet" option for cards and mobile networks, and if you choose a SIM that runs out of money or has no tariff, the Internet won't work, even if everything is fine on the second SIM.
There is also a function of "Assistant". SIM-It can be a map that allows you to switch between operators based on signal quality or cost, but it can work incorrectly, constantly trying to find the "best" network and cutting off the connection. For stable operation, it is recommended to disable this function and rigidly fix the use of the Internet for one particular SIM card.
The MIUI shell allows you to flexibly adjust the traffic limits for each card separately. If you notice that the Internet shuts down on its own at a certain time of the month, check the Statistics section. You may have a limit that the system automatically blocks when you reach a threshold.
- 📞 Check which one. SIM-The card is assigned to transmit data by default.
- 🔄 When calling from the main SIM, the Internet on it can switch to 2G/3G, If the VoLTE function is not enabled.
- ⚙️ Turn off automatic switching SIM-stable-connection cards.
💡
When using two SIM cards, always manually assign one primary one to the Internet to avoid priority conflicts in the Android system.
Hardware reasons and contact with the service
If none of the software methods worked, and the Xiaomi Redmi 8 phone still doesn't see the network or connect to Wi-Fi, there's a high probability of hardware failure, which could be the failure of the antenna module, the plume or the radio module itself on the board, often after falls, moisture or poor-quality repairs.
Pay attention to the behavior of the indicators. If the status bar is constantly on the "No" icon. SIM-"Cards" or "Emergency Calls Only" on a good SIM, the problem is almost certainly hardware. SIM-squash – sometimes it is not fully inserted into the body.
In case of suspected physical breakdown, self-disassembly is not recommended, as you can damage fragile plumes or break the tightness of the case. It is better to contact an authorized service center for professional diagnostics using special equipment.
