How to remove the restriction of mobile Internet on Xiaomi

Xiaomi smartphone owners often face a situation where data rates across the cellular network suddenly drop or the system notifies you of reaching a set traffic limit. It is not always the fault of the carrier. The built-in shell of MIUI and HyperOS has powerful traffic saving tools that can be set up too aggressively by default. Understanding how this system works allows you to return the device to maximum performance.

Sometimes the problem lies in incorrect access point settings or conflict of software modules responsible for prioritizing traffic. Limitation can occur at the level of system services, which mistakenly mistake background processes for malicious activity or simply exceeding quotas. In this article, we will discuss in detail all possible causes of the slowdown and provide step-by-step instructions for their elimination.

Restoring normal network speed requires a consistent approach, you don't have to be a telecommunications expert to do this, you just have to follow the instructions carefully and check the results after each step, and that will help identify the specific node where the artificial braking of the connection took place.

Checking system limits in the Security application

The first and most obvious step is to check the built-in Security app, where Xiaomi has placed a master switch to control traffic flow, often by accident activating the feature or forgetting it after traveling abroad, where limits were necessary to avoid roaming costs.

Go to the app and find the statistics section, which shows current consumption and thresholds, and if the slider is activated, the system will force you to limit your speed or shut down the Internet completely when you reach a set value, and resetting the statistics and turning off the limit solves the problem in most cases.

โš ๏ธ Warning: Disabling system traffic control means you have to monitor gigabytes of your own to avoid unexpected charges by the operator.

In some versions of firmware, settings can be hidden deeper. Search your phone by typing traffic or limit, which will quickly jump to the menu you want, bypassing long partition searches. Make sure that mission-critical applications are not subject to individual restrictions.

When you change the settings, you should restart the device, which will update the network services and apply the new packet filtering rules, and if the speed is not back, then the restriction is at a deeper level or is related to the network configuration.

Setup and reset APN access points

APN (Access Point Name) access points are the gateway between your cellular network and the global Internet. Incorrect settings in this section can cause the phone to use outdated or less productive data protocols. Operators periodically update their requirements, and old settings become irrelevant.

To correct the situation, you need to go to the mobile network settings and select your SIM-Find the "Access Points" item (APN)". Here you'll see a list of available profiles, and often just select the active point again or click the reset button on the factory settings in the menu.

Before making changes to APN, take a screenshot of the current settings โ€“ this will help you quickly restore access if the new settings are not working.

If automatic resets don't work, you can create a new hotspot manually, enter data provided by your operator, or use standard values for your region. Pay special attention to the "APN type" field, where default,supl or similar combination should be indicated.

Once you save a new point, make sure to tick it, the old profile can stay in memory and conflict with the new one, and restarting flight mode will help you re-register with the updated settings.

Using DNS to speed up and bypass locks

One of the hidden reasons for slow loading pages is the use of standard DNS-They can be overloaded or incorrectly routed requests, switch to alternative, faster servers, such as Google. DNS Cloudflare, often gives a noticeable increase in response speed.

In modern versions of Android and MIUI There is a built-in function "Private" DNS". It's in the Connections and Sharing section or through settings search, and enabling this option allows you to encrypt it. DNS-querying and bypassing certain types of traffic filtering.

  • ๐Ÿš€ dns.google is a reliable and fast server from Google, providing a stable connection.
  • โšก 1.1.1.1 is one of the fastest DNS Cloudflare often helps to reduce ping.
  • ๐Ÿ›ก๏ธ dns.adguard.com โ€“ a server that further blocks advertising at the network level, saving traffic.

Enter the address of the selected server in the private DNS settings field and save the changes. The system will check the availability of the server. If the address is entered correctly, the connection will be established instantly. You may notice that the pages have started loading faster, and some ad blockers will stop displaying banners in the browser.

Changing the DNS does not increase the physical speed of the channel, but it does significantly speed up server response times and open heavy web pages.

Resetting network settings and radio module

If the software settings are lost due to a system error or failed update, a complete reset of network settings may be required, which will return all Wi-Fi, Bluetooth and mobile settings to factory values. It is important to understand that saved passwords from Wi-Fi networks will be deleted.

To do this, go to About Phone and select Reset. You'll need to find Reset Wi-Fi, Mobile Internet and Bluetooth settings. Confirm the action and wait for the device to restart. This process takes no more than a minute.

โ˜‘๏ธ Checklist before network reset

Done: 0 / 4

Once the phone is restarted, it will start searching for the network again, which may take a little longer than usual. Make sure that 4G/LTE or 5G is activated in your mobile network settings if it is supported by your tariff and coverage in the area.

Often, after such a reset, phantom limitations that may have been caused by a software conflict of modem drivers disappear, and if the problem persists due to network services sticking, this method should eliminate it completely.

Background Process Analysis and Traffic Saving

The MIUI shell is known for its strict background control policies, which can restrict data transfers to applications it believes are not in use right now, which helps save battery power, but can interfere with messengers, navigators, or cloud synchronization.

Go to the battery settings and find a list of applications, see if there is a background restriction on important programs, select No Limits mode for those services that need constant network access, and this is especially true for email clients and work chats.

Type of applicationRecommended treatmentImpact on the battery
MessengersNo restrictions.Low.
NavigationNo restrictions.High.
Social media.Smart constraintAverage.
GamesLimited (background)Low.

Also, check the Traffic Savings settings at the bottom of the settings menu, which can activate a mode that compresses data or blocks image loading on mobile networks, and disable these features if picture quality and speed are more important to you than the megabytes you save.

Why is the system limiting the background?
MIUI algorithms analyze user behavior: If an application is rarely used but constantly downloads data, the system marks it as a potentially dangerous or consuming resource, and limits its activity to prolong autonomy.

Engineering menu and choice of preferred network type

For advanced users, you can customize the radio module through the engineering menu, which is a hidden section that allows you to manage network priorities, sometimes the phone gets stuck on EDGE or 3G, even though there is stable 4G nearby, due to incorrect prioritization choices.

To enter the menu, open the phone app and dial ##4636##. If the code doesn't work on your model, you can use Activity Launcher to search for hidden activity "Testing." From the menu that opens, select "Phone Information."

Find the option "Set preferred network type." Here you need to select the option that supports maximum speed, for example, LTE/TD-SCDMA/WCDMA/GSM. It is not recommended to choose "GSM only" modes, as this will force the speed to a minimum.

โš ๏ธ Warning: Changing the settings in the engineering menu can cause a temporary loss of signal.Be prepared to restart the device if the network goes completely missing.

Once you select a new network, the phone re-registers in the cell of the cell operator, and watch the indicator in the upper corner of the screen, and if you see a 4G+ or LTE icon, then the setup has been successful and the network type restriction is removed.

Frequently Asked Questions (FAQ)

Why did the Internet speed drop after the MIUI update?
System updates often contain new security patches or changes to power saving algorithms that may conflict with current network settings.
Does crowded cache affect mobile internet speed?
Cache has no direct effect on channel speed, but a crowded cache of Google or browser system services can slow down the processing of network requests. Periodic cleaning of the cache in the Storage section is useful for overall performance.
Can a magnetic case limit the signal?
Yes, some metal or magnetic elements in the cases can shield the antennas of the smartphone, especially if they are located in the receiving area.
How do you know if the operator is speed limiting?
Check the terms of your plan. Many operators reduce speed after the high-speed packet is exhausted, and the limitation may be due to the termination of the service or blocking by the operator for non-payment.
