Slow internet on Xiaomi is a problem that even owners of flagship models like Xiaomi 14 Ultra or Xiaomi have to face. POCO F6 The reasons can lie in the settings of the smartphone itself, and in external factors: an overloaded operator tower, outdated. SIM-In this article, we will discuss 12 proven ways to speed up mobile Internet on Xiaomi, Redmi and other devices. POCO β From basic to advanced, including hidden settings MIUI.
It's important to understand that speed isn't just about your smartphone, like if you're on the subway or on the outskirts of a city, even Xiaomi. 13T Pro with support 5G SA It's not going to be a record high, but 80 percent of the time, it's software-based -- no new phone or tariff change -- we start with diagnostics and simple actions, and then we go to deep optimization.
1. Testing the real speed of the Internet
Before you change anything, measure your current speed. Use not one, but two different applications for accuracy:
- π Speedtest by Ookla β a classic test with the choice of server (it is better to choose your operatorβs server).
- π nPerf β shows not only the speed, but also the stability of the connection (an important parameter for online gaming).
- π± Built-in test in MIUI: Go to Settings. β SIM-maps and mobile networks β Network speed (not available on all models).
Do the test in different conditions:
- π Homes (near the window and in the back of the room).
- π Outside (in traffic and in parking).
- π’ In an office or shopping center.
Critical indicators for mobile Internet in 2026:
| Type of network | Minimum speed (Mbps) | Good speed (Mbps) | Ping (ms) |
|---|---|---|---|
| 4G (LTE) | 5β10 | 30β100 | <50 |
| 5G (NSA) | 20β30 | 100β300 | <30 |
| 5G (SA) | 50β70 | 300β1000+ | <20 |
If your results are below the minimum, move to the next section. If the speed is normal but subjectively slowing down, the problem may be in the middle of the problem. DNS-servers or background processes (more on this later).
2. optimize the settings of the mobile network
By default. MIUI We often choose not the fastest network settings:
Step 1: Selecting a Priority Network Type
Go to Settings. β SIM-maps and mobile networks β [yours SIM] β Type of network:
- πΆ If you have Xiaomi with support 5G (For example, Redmi Note 13 Pro+ 5G), choose 5G (preferably LTE/5G.
- π± On devices without 5G (for example, POCO M6 Pro) install LTE (preferably).
- β οΈ Never choose. 3G or 2G β It'll artificially limit speed.
Step 2: Incorporating carrier aggregation (CA)
This function combines several frequencies 4G/5G to increase speed, to activate it:
- Enter the dialer code ##4636##.
- Go to the tab Information about the phone.
- Scroll down to Set your preferred network type.
- Choose. LTE/NR (auto 5G-device LTE (all bands for 4G.
Select priority 5G/LTE customized SIM|Activate carrier aggregation (CA)|Disable the traffic saving mode|Check the relevance of the modem firmware-->
Step 3: Turning off traffic savings
V MIUI There's a hidden speed limiting function to save charge:
- Go to Settings β Battery and Performance β Battery Mode.
- Choose Performance (if available) or Balanced.
- Turn off the Background Limit option for apps that need fast internet (e.g. YouTube, Telegram).
π‘
If you've lost speed after you change the network type, you can reset your settings and reboot your smartphone. Sometimes the modem needs time to reconnect.
3. Checking. SIM-slot
Old ones. SIM-Cards (released before 2018) don't physically support speeds above 100 Mbps, even if the smartphone and network are capable of more:
How to check your age SIM-map:
- π Look at the map itself: if it is trimmed from a standard (mini-SIM) or has a thick frame, it is outdated.
- π Check the activation date: if the card is more than 5 years old, it is time to change it.
Best options SIM Xiaomi:
| Type SIM | Max, speed. | Suitable for |
|---|---|---|
| nano-SIM (4FF) | Up to 1 Gbps. | All modern Xiaomi |
| eSIM | Up to 2 Gbps (5G SA) | Xiaomi 13/14 series, POCO F5 |
| Universal (combo-SIM) | Up to 300 Mbps. | Budget models (Redmi) A2+) |
How to change SIM numberless:
- Visit the operator's cabin with a passport.
- Ask for it. USIM-card (it supports the card) 5G) eSIM (if your Xiaomi is compatible).
- Activate the new card before removing the old card to avoid locking the number.
β οΈ Note: Some Xiaomi models (e.g. Redmi Note 12) have a second slot SIM only works in mode 2G, This is a slowing down, so use the first slot for the main one. SIM.
4. Change. DNS-servers to speed up loading
Xiaomi is using the default DNS your operator, who are often overloaded. DNS They can make websites open 20 to 50 percent faster. Here's how to change them:
Method 1. via Wi-Fi settings (works for mobile internet too)
- Go to Settings. β Wi-Fi.
- Click on the current network (or add a new one).
- In the section DNS pick it manually.
- Enter addresses (e.g. 1.1.1.1 and 1.0.0.1 for Cloudflare).
Method 2. via Application 1.1.1.1: Faster Internet
This is the official Cloudflare app that automatically selects the fastest. DNS. Download it from Google Play and turn on protection in one tap.
The best public ones DNS for Xiaomi in 2026:
- π Cloudflare: 1.1.1.1 and 1.0.0.1 (the fastest for Russia and CIS).
- π‘οΈ Google DNS: 8.8.8.8 and 8.8.4.4 (stable, but may block some sites).
- π AdGuard DNS: 176.103.130.130 and 176.103.130.131 (block ads).
After shift. DNS Reboot your smartphone and check your browser speed, and you'll notice the acceleration when you open sites like VKontakte, YouTube or Avito.

Shift. DNS It does not increase the download speed of files, but reduces the time of opening web pages and reduces ping in games.
5. Optimize background processes and cache
Even on powerful Xiaomi (like Black Shark 6 Pro), background apps can eat up to 30% of internet speed.
Step 1: Limit background activity
- Go to Settings β Applications β Application Management.
- Select an application (such as Tinkoff or SberBank).
- Press Background Limitation and select Limit.
Step 2. Clear the cache. DNS
Cash. DNS It can contain outdated site addresses, which slows down the opening of sites:
- Enter the dialer: ##2432546##.
- Choose Clear. DNS Cache (if the option is available).
- Or use the app. DNS Changer from Google Play.
Step 3: Disabling Auto-Update Applications
By default, Google Play updates apps over Wi-Fi and mobile to prevent mobile Internet updates:
- Open Google Play β click on the profile avatar.
- Select Settings β Network β Auto-Update applications.
- Install only via Wi-Fi.

6. Advanced settings for experienced users
If the basic techniques didnβt help, try these hidden tricks (require root rights or an engineering menu):
Method 1: Change the modem protocol type
Some protocols (e.g, IPv4/IPv6) They're working faster than others:
- Enter the dialer: ##4636## β Phone information.
- Scroll down to Set your preferred network type.
- Try the options: LTE only if 5G unstable). NR/LTE/TD-SCDMA (for maximum compatibility).
Method 2: Enabling Band Lock (frequency fixing)
If your Xiaomi is constantly switching between frequencies (for example, from Band 3 to Band 20), this slows down.
- Install the Network Signal Guru app (requires root).
- Select the frequency with the best signal (e.g. Band 7 for MegaFon).
Method 3: Updating the modem firmware
The modem firmware is responsible for the operation of network chips. On some Xiaomi (for example, Redmi Note 11 Pro).+ 5G) You can update it separately:
- Download the latest version of modem firmware for your model from the forum 4PDA.
- Fastboot through the Fastboot or TWRP (instructions are in the archive with firmware).
Solution: Clean the connector gently with alcohol or replace the tray (worth it) ~300 rubles).
Problem 2: Overheating of the modem chip
On Xiaomi with Snapdragon processors (for example, POCO X6 Pro) the modem may overheat and slow down. Check the temperature:
- Install the AIDA64 application.
- Run the network test and monitor the temperature of the Snapdragon chip X65 (or another modem).
- If the temperature is above 70Β°C, remove the case and let the phone cool down.
Problem 3: Faulty antenna
If the speed drops when holding the phone in a certain way (for example, in a horizontal position), the antenna cable may break, as is typical for Xiaomi after a fall, the solution is to replace the antenna module in the service center.
