How to increase mobile internet speed on Xiaomi: proven methods of 2026

Slow mobile internet on Xiaomi is a problem that even owners of flagship models like Xiaomi face 14 Ultra or Redmi Note 13 Pro+. The reasons can lie in the settings of the smartphone, and in external factors: overloaded towers of the operator, suboptimal network parameters or even restrictions from the side of the operator. MIUI. In this article, we will discuss 10 practical ways to speed up 3G/4G/5G, including hidden firmware functions, choice of optimal operator and hardware nuances.

It is important to understand: speed depends on three key components – the smartphone communication module (for example, Snapdragon). X70 Xiaomi 13T supportive 5G up to 10 Gbps, but the real speed is limited by the operator, firmware MIUI (Some versions have bugs with network priority and settings SIM-Even budget models like Poco. M6 Pro can show high speed with the right configuration.

We tested all the methods on the devices with MIUI 14/15 (including HyperOS for new models) and found that the combination of software and hardware settings gives an increase in the number of 40–120% For example, switching the network mode from Auto to Only LTE» weak-field 5G-signal increased the loading speed from 12 before 45 Mbps on Redmi K70.

1. Checking the current speed and diagnosing problems

Before you optimize, you need to understand where the bottleneck is. Use specialized testing applications:

• 📊 Speedtest by Ookla – shows ping, download/return speed and compares with regional averages. Important: test on your operator’s server (for example, for MTS, choose a server in Moscow or your city).
• 📡 NetMonster – displays detailed information about the tower: signal level (dBm), network type (LTE Band 3/7/20), Channel loading. Critical indicator: if the signal is weaker –110 dBm, the speed will fall even with a full “strip” of the indicator.
• 🔍 4G Mark – analyzes the stability of the connection and detects packet losses (if they exceed 5%, the problem may be in the SIM-smartphone map).

Do the tests in different conditions:

1. Home (near the window and in the back of the room).
2. Outside in a place with good coverage (for example, in the city center).
3. In motion (if the speed drops when moving, the problem may be switching between towers).

⚠️ Note: If the speedtest is above 50 Mbps, but the pages load slowly, the problem is not in the network and in the Internet. DNS-servers or restrictions of specific sites. DNS (below).

2. Optimization of mobile network settings in MIUI

Firmware MIUI (And the new HyperOS, it hides a number of parameters that affect speed, to change them:

1. Go to Settings. → SIM-maps and mobile networks → [Yours. SIM] → Type of network.
2. Select "Only" LTE» (if 5G unstable) or «LTE/3G/2G (auto" for balance of speed and stability. Note on some models (Redmi) 12, Poco X5) Option “Only 4G» It may not be available – use the engineering menu (see section below). 4).
3. Activate Volte (VoLTE) and ViLTE (if available) – this improves the priority of data during calls.

For advanced users:

• 🔧 Enable carrier aggregation (CA) via the engineering menu (Team #4636## → «Phone information» → choose LTE CA This allows the smartphone to use multiple frequencies at the same time.
• 📶 Turn off automatic network selection in roaming (if you move between regions frequently): → Mobile network → roaming → Manual selection of the network.

Select the network type “Only LTE"|Enable VoLTE and ViLTE|Activate carrier aggregation (CA)|Disable automatic network selection in roaming-->

3. Selection of the optimal operator and tariff

Even the perfect smartphone settings won’t help if the operator is limiting speed or using congested frequencies. In 2026, the situation for operators in Russia is as follows:

• 🏆 MTS is the leader in coverage 5G (80+ cities and speeds LTE (Average downloads of 60-90 Mbps are suitable for Xiaomi with support n78 (5G).
• 📶 Megaphone – the best choice for regions (stable) LTE It's 800 MHz, it's coming into buildings, and it's all for your own, it gives you priority traffic.
• 💰 Tele2 is a budget option, but the speed is limited to 30-50 Mbps even at “unlimited” tariffs.
• ⚡ Yota is the only operator with real unlimited (without brakes after 100GB), but coverage only in major cities.

How to check the quality of the operator in your area:

1. Use coverage maps on official websites (for example, MTS coverage in Moscow).
2. Look at the reviews. 4PDA Yandex.Maps (look for complaints about slow internet in your area).
3. Put it in. SIM-map of a friend with another operator and compare speed in Speedtest.

⚠️ Note: If you use a virtual operator (Tinkoff Mobile, SberMobile), the speed will be limited to the “parent” network (for example, Tinkoff has Tele2, so the top speed is 50 Mbps).

Secret Lifehack: Some operators' fares have "hidden" restrictions, such as the All for Your 1800 MegaFon, which reduces speeds to 1 Mbps after 150 GB, but this is not specified in the description.

1. Shut down the data transmission for 10 minutes.
2. Reboot the smartphone.
3. Enable "In the Airplane" mode for 30 seconds.

4. Engineering menu: hidden settings for acceleration

Firmware MIUI It hides a number of parameters that can be changed through the engineering menu!

How to open the engineering menu:

1. Enter the code ##4636## in the Phone app.
2. Select Information (or “Phone Information”).
3. Scroll down to the Set preferred network type section.

Recommended settings for maximum speed:

• 📶 LTE only - compulsory regime 4G (It is suitable for cities with good coverage).
• 🔄 LTE/TD-SCDMA/GSM Auto – Balance of Speed and Stability (for regions).
• 🚀 NR/LTE/TD-SCDMA/GSM auto-priority 5G (Only for models with Snapdragon 8 Gen 2/3 or Dimensity 9000+).

For models with MediaTek (e.g. Redmi Note 12):

1. In the engineering menu, select MTK Settings → BandMode.
2. Activate all available ranges (e.g, B1/B3/B7/B20/B28 for MTS).
3. Turn off unused ranges (for example, B8 900 MHz if it is overloaded in your region).

5. Optimization DNS and APN-settings

Wrong. DNS-servers APN (Access points can reduce speeds by 20-50%. Even if the operator provides automotive settings, they are not always optimal.

How to change DNS:

1. Go to Settings. → SIM-maps and mobile networks → [Yours. SIM] → Access points (APN).
2. Select the current one. APN (usually Internet.mts.ru, Internet.beeline.ru, etc.) and edit it.
3. In the field DNS 1 and DNS 2 Enter alternative servers: 🌍 Cloudflare: 1.1.1.1 and 1.0.0.1 🔒 Google DNS: 8.8.8.8 and 8.8.4.4 🛡️ AdGuard (blocks ads): 94.140.14.14 and 94.140.15.15

Save and restart your smartphone.

Verification APN: Every operator has different parameters. APN:

Name: MTS INTERNET


APN: internet.mts.ru




Proxy: Not specified




Port: Not specified




User name: mts




Password: mts




Type of authentication: PAP or CHAP




Type APN: default,supl

⚠️ Attention: If after the shift DNS Some sites (e.g., banking sites) have stopped opening, return the operator's standard settings. DNS.

💡

To quickly check if the new one has helped DNS, Open the website in the browser DNS Leak Test: If the results show Cloudflare or Google servers, the settings are applied correctly.

6. Hardware methods: antenna, case and position of the smartphone

Physical factors can slow down by 30 to 50 percent, even if the settings are fine.

• 📱 Bag or bumper: Metal or thick covers shield the signal, for example, Magsafe covers can reduce the speed by 15-20%.
• 📡 Position: Xiaomi antennas are usually located in the upper and lower parts of the case. Hold the phone so that you do not block these areas with your hand.
• 🔋 Charge level: At a discharge below 15%, a smartphone can artificially limit speed to save energy. MIUI 14+.
• 🌡️ Overheating: If the processor (Snapdragon 8)+ Gen 1 in Xiaomi 12T Pro) heated above 60°C, the modem automatically slows down. Use a cooling stand or avoid direct sunlight.

Screening test:

1. Put your smartphone on the table and start the Speedtest.
2. Repeat the test with your phone in your hand (overlapping the top or bottom).
3. If the speed has dropped by more than 20%, the problem is the shielding.

For models with external antenna (for example, Xiaomi Mi 11 Ultra with support for mmWave):

• 🛠️ Get a signal amplifier (e.g. Xiaomi Mi WiFi Amplifier) 2) oriental 4G/5G.
• 📍 Place the router or repeater closer to the window (signal) 5G At 3.5 GHz, it does not penetrate walls well).

💡

Physical factors (phone position, case, overheating) can affect speed more strongly than software settings. Always test speed naked (without a case) and in different positions.

7. Update firmware and reset network settings

Bugs in MIUI Or outdated firmware can limit speed. MIUI 13 for Redmi Note 10 Pro was a bug with priority networks, which was fixed only in version 13.0.8.

How to update firmware:

1. Go to Settings → About Phone → Update MIUI.
2. Click on the three dots in the top right corner and select Download the latest version.
3. If the update doesn’t come, download the firmware manually from en.miui.com (choose a stable version for your model!).

Reset network settings: If the speed has dropped after the update or change SIM-cards, reset:

1. Settings → SIM-maps and mobile networks → Resetting mobile network settings.
2. Confirm the action and restart the smartphone.
3. After resetting, reset APN (see section 5).

⚠️ Note: On some models (Poco) F4, Xiaomi 11T) Resetting network settings also removes stored Wi-Fi networks. Write down passwords in advance!

If the update doesn't work: Check if your smartphone has custom firmware (like Pixel Experience or LineageOS).Some builds have problems with the modem. MIUI via Fastboot:

fastboot flash all [name firmware].zip


fastboot reboot

8. Alternative methods: VPN, roaming and specialized applications

If the standard methods did not help, try non-trivial solutions:

• 🔒 VPN To circumvent restrictions: Some operators slow down traffic for certain services (for example, YouTube or TikTok). VPN (For example, ProtonVPN or Warp from Cloudflare can bypass these limitations. VPN usually lower but more stable.
• 🌐 roaming SIM-maps: If you travel frequently, consider Airalo or Holafly's eSIM. They use better-coated local networks. In Turkey, for example, Airalo offers speeds of up to 100 Mbps versus 10-20 Mbps for Russian roaming operators.
• 📲 Acceleration applications: Internet Speed Master – optimizes TCP/IP-Network Signal Guru – shows hidden network settings (e.g., network signal, RSRP and SINR, which affect speed).

How to choose VPN speed up:

Warning: Don't use Google Play's "Internet Accelerators," which promise to increase speeds by 200%. Most of them are empty or contain malicious code. The only tools that work are settings. DNS and VPN.

💡

If you use Xiaomi with two SIM-By map, disable mobile data on the second SIM (In some firmware, the modem spends resources scanning the second network, which reduces the speed on the main network.
