Enabling access to the global network on Xiaomi, Redmi or Poco smartphones usually happens automatically immediately after installation. SIM-However, there are often situations where the indicators are 3G/4G They don't light up, and sites stop opening even when there's a balance, which can be due to an incorrect access point setting or a malfunction of the network module of the device.
Before you panic and bring a gadget to the service, you need to conduct a basic diagnosis, because in 90% of cases the problem lies in the software. In this article, we will discuss all possible ways to restore the connection, from simple switches to manual registration of operator parameters.
Mi UI and HyperOS owners face different interfaces, but the logic of network settings remains the same for all versions of Android. We will look at the algorithms of actions that will help to return online mode in the shortest possible time without losing personal data.
Quick activation through the control panel
The most obvious and quick way to start data transfer is to use a notification curtain, which is to swipe from the top edge of the screen down to open the quick settings menu, and find an icon that says Mobile Internet or Mobile Data and tap it to light it up.
If the icon is active but the network is not working, try switching network modes. Hold your finger on the mobile Internet icon or go to settings to select your preferred network type. Sometimes forced switching to 2G/3G/4G helps you reconnect to the operator tower.
💡
If the mobile internet icon is missing from the curtain, edit the quick button list by clicking on a pencil or edit button, and drag the icon to a prominent place.
In some cases, the system may block data transmission to save traffic or battery. Check if the flight mode is turned on, which completely disables all wireless modules. SIM-The map is determined by the system correctly.
⚠️ Note: If after switching on the mobile Internet icon 4G or+ appears, but the pages do not load, the problem may not be in the phone, but on the operator’s side.
Setting up an APN access point for different operators
The most common reason for the lack of Internet access is the incorrect or misconfiguration of the APN (Access Point Name) access point, which tells the phone which gateway to access the network, usually comes automatically, but when you manually change the SIM or flash it, you have to re-enter it.
To set up, go to the Settings menu → SIM-maps and mobile networks → Choose. SIM-map → Access points (APN). Here you will see a list of existing profiles. If the list is empty or the current profile is not working, click the button. + or a new access point at the bottom of the screen.
☑️ Checking settings APN
In the window that opens, you need to enter the data corresponding to your operator. It is critical to fill in the Name and APN fields correctly, the remaining parameters can be left by default or also filled in according to the table below.
| Operator. | Name (Name) | Access Point (APN) | Type APN |
|---|---|---|---|
| MTS | mts internet | internet.mts.ru | default,supl |
| Beeline | Beeline Internet | internet.beeline.ru | default,supl |
| Megafon | Megafon | internet | default,supl |
| Tele2 | Tele2 Internet | internet.tele2.ru | default,supl |
Once you have entered, be sure to click the menu (three dots in the corner) and select Save. Then activate the created access point by ticking next to it. Rebooting the device after this procedure often fixes the changes.
What to do if the settings are not saved?
Solving problems with Wi-Fi connection
When it comes to Wi-Fi wireless networks, the problems often lie in conflict. IP-addresses or incorrect settings DNS. If your Xiaomi sees the network, connects to it, but writes “Connected, no Internet access”, the first thing you should try is to forget the network.
Go to your Wi-Fi settings, click on your network name, and select Delete or Forget the network. Then re-enter the password. This action clears the connection cache and causes the phone to request a new one. IP-router.
Another effective measure is the change of DNS-In the Wi-Fi settings, click on the arrow next to the network name, find the Settings section. IP and switch with DHCP static.
- 📶 In the field DNS 1 enter the value of 8.8.8.8.
- 📶 In the field DNS 2 enter the value of 8.8.4.4.
- 📶 Save the changes and check the page loading speed.
If you’re using a dual-band router, try switching from 5GHz to 2.4GHz or vice versa.Some older Xiaomi smartphone models may not work with certain bandwidth channels.
💡
Changing the DNS to 8.8.8.8 solves the “Connected without Internet” problem in 80% of cases when the router is serviceable.
Resetting network settings to factory
If manual manipulations don’t work, you can use the full network reset feature, which will return all mobile, Wi-Fi and Bluetooth settings to their original state, but will not delete your personal files, photos or contacts.
To perform the operation, go to Settings → Connection and Sharing → Reset Wi-Fi, mobile networks and Bluetooth. The system will warn you that all stored Wi-Fi passwords and associated Bluetooth devices will be deleted.
This method is especially useful when there is a buildup of software debris in the system or a conflict after the Mi UI update. Once reset, the phone will reboot and you will have to re-enter passwords from home wireless networks.
⚠️ Warning: Resetting your network settings will remove all saved Wi-Fi passwords and Bluetooth pair history. Make sure to remember your home network password before starting the procedure.
In some cases, especially on global firmware, it may be necessary to reset settings to factory (Hard Reset), but this method should be resorted to only as a last resort, having previously made a backup copy of the data.
Diagnostics SIM-maps and physical contact
You can't rule out the physical factor, if the phone doesn't see the network or constantly says, "No." SIM-The problem may be contamination of the contacts or damage to the SIM itself.
Wipe your contacts. SIM-Soft dry cloth or stained oxides can prevent normal communication between the module and the card, and check if the card is sitting tightly in the tray and hanging around.
Try to rearrange. SIM-card to another slot (if there are two) or to another phone, which will help you understand where the malfunction lies: in the card of the operator or in the network module of the Xiaomi smartphone.
- 🔍 Check the tray. SIM-damage-card.
- 🔍 Make sure the card is installed on the correct side (by the scheme on the tray).
- 🔍 Check whether the data transfer service on the number is active through the operator’s personal account.
If the card is old (used for more than 5 years), its capacity and standards may not meet modern network requirements. 4G. In this case, you should contact the communication salon for a free replacement. SIM-number-card.
Using an engineering menu to amplify the signal
For advanced users, there is a way to force network type selection through an engineering menu that can help in areas of uncertain reception, where the phone is constantly "jumping" between 3G and 4G, breaking the connection.
Open the Phone app and dial the combination ##4636##. If the menu opens, select Phone Information. Find the Setup preferred network type section.
Settings of the preferred network type:
LTE only (4G only)
NR/LTE/GSM (5G/4G/3G/2G vehicles)
GSM only (2G only)Choose LTE only if you are in 4G coverage, but the signal is weak. This will prevent the phone from switching to slower but stable 3G networks. Be careful: in this mode, incoming calls may not pass unless VoLTE technology is configured.
