How to speed up the Internet MegaFon on Xiaomi smartphones: a complete guide

Slow internet on Xiaomi with a MegaFon SIM card is a problem that many users face. Speed can sag due to incorrect network settings, congested operator towers or features of MIUI firmware. In this article, we will analyze 12 proven ways to speed up mobile Internet, from basic settings to hidden functions of the engineering menu.

It's important to understand that speed depends not only on your smartphone, but also on the network coverage in your area, but even in low signal areas, the right settings can increase speed by 30 to 70 percent (as tested on the Redmi Note 12, POCO X5 and Mi 11 models with MIUI 14 firmware).

1. Basic speed check and problem diagnosis

Before you set up anything, you need to know where the connection is braked. Use speed testing apps:

• 📊 Speedtest by Ookla – shows ping, upload/return speed and the nearest server.
• 📡 NetMonster – Analyzes signal strength, network type (4G/5G) and adjacent towers.
• 🔍 G-NetTrack Pro – displays detailed connection information (LTE-ranges, CA-aggregation).

Run the test in different places (home, street, subway) If the speed is low everywhere, the problem is with the settings of your smartphone or SIM card. If only in certain areas, the coverage of MegaFon is to blame.

• RSRP (Signal Level): Optimally -85 dBm and higher (the closer to 0, the better).
• CA (Carrier Aggregation): If multiple bands are displayed (e.g. B3+B7+B20), the speed will be higher.

If the test results show that the smartphone is connected to a 3G (H+) network instead of 4G (LTE) or 5G, then move on to the next section.

2. Forced switch to 4G/5G

By default, Xiaomi on MIUI can automatically switch to 3G or 2G to save charge. This reduces speed, but increases the time of operation. To lock in the priority of 4G/5G:

1. Open the Settings. → SIM-maps and mobile networks.
2. Select your MegaFon SIM card.
3. Go to Network Type (or Preferred Network Type).
4. Install LTE only (for 4G) or 5G/LTE (if supported).

On some models (e.g. Redmi 10C or POCO M4 Pro), this item may be called Network Mode. If there is no LTE-only option, use the engineering menu (section 5).

💡

On smartphones with MediaTek (for example, Redmi Note 11) after forced on 4G, voice communication may disappear. In this case, select LTE/3G/2G (auto), but turn off the VoLTE option in the SIM card settings.

3.APN setup for MegaFon

Incorrect APN settings (access points) are one of the main reasons for slow Internet. Even if the smartphone automatically loaded the settings, they can be outdated. Manually write the current settings for MegaFon (2026):

1. Go to Settings. → SIM-maps and mobile networks → [Yours. SIM] → Access points (APN).
2. Click Add Access Point or select an existing one.
3. Fill in the fields according to the table:

Once you save, restart your smartphone. If the Internet doesn't work, check that the hotspot is selected (check next to the name). Some MIUI firmware may reset the APN selection after the update - watch for that.

4. Optimization of MIUI settings for speed

MIUI has hidden features that affect Internet speed, some of which can be configured without root rights:

• 🚀 Turn off Traffic Savings: Settings → Connections and sharing → Saving traffic → Turn off the slider. This feature limits background traffic, which can slow down speed.
• 🔄 Reset network settings: Settings → The phone. → Resetting settings → Reset your Wi-Fi, mobile network and Bluetooth settings, and then you have to re-enter your Wi-Fi passwords and configure them. APN.
• 📵 Turn off the "Smart Assistant": Settings → Battery and productivity → Smart assistant. → Deactivate the option. It can block background activity of applications using the Internet.

For advanced users: MIUI 13/14 has a hidden Network Mode option that allows you to manually select 4G bands.

1. Enter the phone code in the app: ##4636##.
2. Select Phone Information.
3. In the Set preferred network type, set LTE only.

5. Engineering menu: hidden network settings

The Engineering Mode allows you to fine-tune the modem settings, which is especially useful for Xiaomi smartphones on MediaTek or Qualcomm processors.

To open the menu:

• For MediaTek: Enter the Phone app code ##36446337##.
• For Qualcomm: Use the code ##4636## → Phone information.

From MediaTek menu, go to BandMode and do:

1. Select SIM 1 or SIM 2 (depending on the SIM card slot).
2. Install LTE Mode → All Bands (or manually select MegaFon bands: B3 (1800 MHz), B7 (2600 MHz), B20 (800 MHz)).
3. Activate LTE CA (Carrier Aggregation) to combine ranges.

For Qualcomm, select LTE only under Set preferred network type and enable Enhanced 4G LTE Mode (if any).

💡

Setting up the ranges in the engineering menu gives you up to 40% speed gain, but requires an accurate knowledge of the frequencies supported in your area. Use the NetMonster app to find out which ranges are active at the nearest MegaFon towers.

6.Problems with SIM card and operator

Sometimes the slow Internet is not connected to the phone, but to the SIM card or the tariff.

• 🆔 Tariff plan: MegaFon's All for Yours and Neogran rates may limit speed after high-speed traffic has run out. Go to the MegaFon app or website to check the remaining gigabytes.
• 🔄 SIM card re-issue: If the SIM card is older than 5 years, it may not support modern standards (e.g., VoLTE or SIM card) 5G). Contact the MegaFon salon for a new one USIM-card.
• 📍 Roaming: If you are in a region where MegaFon roams (for example, Crimea, some regions of the Far East), speed may be artificially limited.

It is also worth checking whether you have activated paid services that limit speed (for example, “Children’s Internet” or corporate restrictions).

1. Call *105# and call.
2. Check the list of active services in response from the operator.
3. Disable unnecessary commands *105*001# (to disable all paid services).

7. Alternative acceleration methods

If standard methods don’t help, try these solutions:

• 🔧 Change. DNS: By default, MegaFon uses DNS-Operator servers that can slow down. Go to Settings → Connections → Private DNS and specify dns.google (Google) DNS) 1dot1dot1dot1.cloudflare-dns.com (Cloudflare)
• 📱 Turn off the second. SIM: If you use two SIM cards, the second one can interfere with the stable connection. Try temporarily removing it or disabling it in the settings.
• 🔄 Update the firmware: in new versions MIUI Frequently fix modem errors. Check the updates in Settings → The phone. → Updating the system.
• 🛠️ Reset to factory settings: if nothing helps, complete a full reset (Settings) → The phone. → Settings reset. Attention: this will delete all data from the phone!

For owners of Xiaomi with unlocked bootloader there is another way – firmware custom modem (for example, Modem Firmware from developers). XDA). It's a risky method, but it can give you a speed increase of 20-50%. 4PDA or XDA Developers for your model.

8. Hardware problems: when nothing helps

If all the software methods have been tried and the internet is still slow, the problem may be the hardware:

• 📶 Antenna or modem: Physical damage (e.g. after a fall) can impair signal reception.
• 🔋 Battery: If the battery is swollen, it can push the board, disrupting the connection with the antennas.
• 🛠️ Modem soldering: on some Xiaomi models (for example, Redmi) 9A) The modem chip is soldered off over time, and it needs repairs at the service center.

To check the hardware:

1. Call a phone with another SIM card (such as MTS or Beeline), if the speed is normal, there is a problem in the MegaFon or SIM card.
2. Connect to Wi-Fi. If the speed is high, it's the mobile modem's fault.
3. Check your smartphone across town/region, and if it's slow everywhere, it's the phone.

💡

If the smartphone stopped catching the network after falling or getting moisture, do not try to disassemble it yourself.

⚠️ Note: On Xiaomi models with a MediaTek Helio G processor (e.g. Redmi 10, POCO M3) You can get your network out of the box after you run custom software. NVRAM through SP Flash Tool.
