How to speed up mobile Internet Tele2 Xiaomi: the full guide

Xiaomi smartphone owners often face a situation where Tele2 mobile Internet speeds do not meet the stated tariff plans, which can be due to overloading of base stations during peak hours, and the incorrect software settings of the device itself. Unlike other operators, Tele2 network actively uses the 1800 MHz (Band 3) frequency band in cities, which requires a precise modem configuration for stable operation.

The Android-based MIUI operating system has its own power management features that sometimes aggressively restrict background data transfer, which is done to save battery power, but as a result, web pages can load longer and video content can be buffered, and the right network settings allow you to bypass these limitations and squeeze the maximum out of the carrier’s coverage.

In this article, we will look at an integrated approach to connection optimization, starting from basic verification. SIM-It's important to understand that software methods can't improve a signal where it's not physically available, but they guarantee that all available network resources are used.

Diagnostics of current signal speed and quality

Before making changes to system files or settings, you need to get objective data about the current state of the network. The subjective feeling of “slow Internet” is often misleading, since the speed can drop due to the congestion of a particular site, rather than the communication channel. Use specialized applications for measuring speed, such as Speedtest by Ookla or nPerf, conducting tests at different times of the day.

If you see a 3G or H+ icon in a place where 4G should be, the problem is that the device is logged in. The smartphone may get stuck on an old tower or use an outdated communication standard due to a failure in the roaming preference table.

• 📡 Network type: Make sure it is displayed LTE or 4G+, Which indicates high-speed operation.
• 📶 Signal level (RSRP): In the engineering menu or through the applications, see the value RSRP; It should be better. -105 dBm for confident admission.
• 📉 Ping: Check the delay; for Tele2 is considered normal 40-50 ms.

⚠️ Note: If the signal level is constantly lower -115 dBm, the software settings may not help, and in this case, the problem is with the physical location of the base station or the shielding of the building.

It's also worth checking if the phone is running Traffic Savings. MIUI It can block background sync and preloading of content, making the Internet seem slow. SIM-Maps and mobile networks for honest tests.

Verification SIM-maps and physical connections

Often the cause of low speed is the banal contamination of contacts. SIM-The card or its physical wear. Tele2, And like others, they use maps of different generations. SIM-The card was cut from an old "block" or more 5-7 In the years to come, it may not support modern encryption and data rate standards.

It is recommended to replace the old card with a new USIM-based Nano-SIM card in the operator’s cabin.It is free or costs symbolic money, but guarantees compatibility with all modern LTE Advanced standards. When installed, make sure that the card sits tightly in the tray and does not hang around.

If your Xiaomi uses a two-sim slot, check the traffic distribution settings. MIUI By default, the main slot for the Internet can be assigned to SIM-the card of the other operator, if it was set first. → SIM-maps and mobile networks.

In some cases, a simple cleaning of the tray contacts helps. SIM-Blow the slot with compressed air or gently wipe the contacts of the card with a soft dry cloth. Contact oxidation is a common cause of unstable connections, especially if the phone was operated in high humidity conditions.

Configure APN access points for Tele2

The most effective software way to speed up the Internet is by manually registering access points (APNs). Automatic settings that come into SMS often contain outdated settings or gateways leading through intermediary servers. Manually configuring allows you to set a direct connection to the operator's gateways.

To enter the settings menu, go on the Settings path → SIM-maps and mobile networks → (Choose. SIM Tele2) → Access points (APN). Click the "New Access Point" button or the plus icon, and it's important to enter the data without errors, observing the letter register.

Enter the following settings to create a new access point:

After filling in all the fields, be sure to save the profile by clicking on three dots in the menu or the Save button, and activate it by ticking.Rebooting the phone after this procedure is mandatory for the application of changes.

There is a nuance for subscribers with speed limits after packet exhaustion. Changing APN will not remove these restrictions, since speed control is on the operator server side (PCRF). However, for full unlimiteds and large packet tariffs, this often solves the problems with the "dumbness" of the Internet.

Forced choice of network type and ranges

Xiaomi smartphones are set to automatically select the network (preferably 4G) by default. In unstable coverage, the phone can constantly "jump" between 3G and 4G, causing connection breaks and loss of data packets. Forced switching to LTE only mode can stabilize the channel.

To do this, go to Settings → About → MIUI version and quickly press 7-10 times on the version to activate the developer menu. Then in the advanced settings, find “Preferred Network Type” and select Preferred LTE. Be careful: this mode may not work incoming calls unless VoLTE technology is enabled.

⚠️ Attention: Mode “Only” LTE" (LTE Only) may not be available in the standard menu, and activation often requires the code ##4636## to be entered in the phone book, but on newer versions. MIUI This code may be blocked.

If the code doesn't work, you can use the Force LTE Only (4G/5G) app from Google Play. It opens the Android hidden engineering menu where you can lock in the network mode. Select Phone Information and in the drop-down list of Set Preferred Network Type, find the option marked LTE Only.

This is a good way to use it in places where 4G is weak, but 3G is great, and you need fast internet for navigation or messengers, and in such cases it is better to stay on 3G than to lose the connection at the 4G border.

Optimizing MIUI settings for networking

MIUI is known for its aggressive optimization, which can kill background processes needed to maintain stable PING in games or video calls, and eliminate system services and applications from power saving mode.

Go to the Security app (green lightning icon), select Battery and find the savings settings. For active applications that require constant connection (navigator, messengers), set the No Limits mode, which will prevent Wi-Fi module or mobile data from turning off when the screen is off.

Also check your DNS settings. By default, you use your provider’s servers, which can be slow. Connection settings (Settings → Connection & Sharing → Private DNS) can prescribe a fast DNS address, such as from Google (dns.google) or Cloudflare (1dot1dot1dot1.cloudflare-dns.com), which often speeds up the opening of “heavy” sites.

• 🚀 Channel aggregation: Make sure that Carrier Aggregation is included in the engineering menu if your tariff and tower support it.
• 🔒 Blockers: Temporary disabling of built-in antivirus or third-party ad blockers will help diagnose whether they are slowing down traffic.
• 🔄 Network reset: In extreme cases, use the function "Reset settings Wi-Fi, mobile Internet and Bluetooth" in the menu settings of the phone.

Remember that the accumulated cache of system applications can also affect the overall responsiveness of the network. Periodic cleaning of the cache of the Settings and Phone application through the application menu can improve the situation.

Use of engineering menus and hidden codes

For advanced users, a deeper level of customization is available through the engineering menu. On Xiaomi, login is done by code ##6484## (CIT) or #3646633## (MediaTek, on older models) on Qualcomm processors (most modern Xiaomi) the menu is often hidden and requires the installation of a special device. APK-file.

In the engineering menu, you can see detailed information about the connected tower (Cell ID), noise level and signal power, which helps you determine whether you are in a confident reception zone, and if you see high interference, changing the position of the phone or moving a few meters can give you an increase in speed.

adb shell service call phone 2 s16 "preferred_network_mode" i32 9

The above is an example. ADB-A command that can be executed from a computer to force the switching of network modes if standard methods do not work. ADB requires the inclusion of debugging USB and install drivers that are suitable only for experienced users.

💡

Before entering the engineering menu, take a picture of the initial settings just in case. Changing unknown parameters can lead to loss of communication or unstable operation of the radio module.

Also available in the engineering menu is the Ping Test function: Run the test to the operator server (for example, to the Tele2 gateway) directly from the phone menu to check the quality of the channel without load from running applications.

External factors and firmware update

You don't have to discount the state of the software shell. MIUI There may have been errors in modem drivers that have been patched in updates. → On the phone, sometimes carriers release security patches that improve network compatibility.

External factors such as the case also play a role. Metalized cases or magnetic-latch cases can shield an antenna located at the top or bottom of the Xiaomi body. Take off the case and check the speed - if it has grown, the accessory is the problem.

Also, the load on the Tele2 base station in your area can be critical. In the evening, when all the neighbors are watching video, the speed drops for everyone. In this case, only waiting or switching to Wi-Fi will help. However, the right settings of APN and DNS can give you a slight advantage in the packet queue.

⚠️ Attention: Installing custom firmware or modified cores (Kernel) can speed up the Internet with new drivers, and completely disrupt the radio module.

In conclusion, complex tuning is not a single step, it's a set of actions. SIM-Maps, the right access point and power-savings cutoffs have a cumulative effect that often exceeds users’ expectations.

💡

The most significant increase in speed is the replacement of the old SIM-New and manual card APN protocolly IPv4/IPv6.
