How to speed up the Internet on Xiaomi Redmi smartphone with Tele2 SIM card: the full guide

Slow mobile internet on Xiaomi Redmi with Tele2 SIM card is a common problem that can arise both from the phone settings and from the operator’s characteristics. Unlike MTS or Beeline, Tele2 often uses networks (roaming with other operators), which affects connection stability. In this article, we will discuss 10 proven ways to speed up the Internet, from basic MIUI settings to fine-tuning APN and choosing a tariff plan.

It's important to understand that speed depends on three key factors: phone setup (firmware, network mode, APN), Tele2 coverage quality in your area, and base station load. If Tele2 roams with MegaFon in your area, speeds may be artificially limited. We tested all methods on Redmi Note 10/11/12 Pro, POCO X3/X4 and Redmi 9A/10A models, the results are shown in the table below.

1. Check the real speed of the Internet

Before you set up something, measure your current speed. Use independent services, not built-in tests from Tele2:

• 📊 Speedtest by Ookla -- shows ping, download and recoil. Choose a server. Tele2 or MegaFon (if roaming).
• 🌐 FAST.com (from Netflix) – Tests streaming speed, which is important for YouTube and social networks.
• 📱 The application “Internet meter” – monitors the speed in the background.

Compare the results with the tariff restrictions of Tele2:

If your speed is below Real by more than 50%, the problem is on the phone or APN settings. If the speed corresponds to the tariff, but you do not like it, read the section about changing the tariff plan.

2. optimize network settings in MIUI

Xiaomi Redmi on MIUI firmware (especially 12-14) often chooses suboptimal network settings by default.

1. Network Mode: Go to Settings → SIM-maps and mobile networks → [yours SIM Tele2] → Type of network. 4G (preferably or only 4G. If you have a Redmi Note 11 Pro+ 5G Or newer, try it. 5G/4G/3G/2G, But keep in mind that Tele2 supportive 5G only in the major cities.
2. Roaming: In the same menu, turn on National roaming – this will allow you to connect to the towers of MegaFon with a weak Tele2 signal.
3. VoLTE and VoWiFi: Enable Settings → SIM-map → Additionally. → Challenges by 4G. This will improve the quality of communication and free up resources for the Internet.

Select 4G only or 4G (preferably) |

Insert "National roaming" |

Activate VoLTE (Calls over 4G)|

Disable "Auto-connection to Wi-Fi" (if not used)-->

For models with MediaTek (Helio G88/G96, etc.): these chipsets often suffer from sticking on weak cells. To reset the connection, turn on Flight Mode for 10 seconds, then turn off. This will cause the phone to reconnect to the nearest tower.

3. Set up APNs for Tele2 manually

Incorrect APN (Access Point Name) settings are one of the main reasons for slow internet. Tele2 automatically sends settings, but they can get lost after MIUI updates or resets.

1. Go to Settings. → SIM-maps and mobile networks → [yours SIM] → Access points (APN).
2. Click Add Access Point and enter:

After saving, restart your phone. If the Internet is not working, check that the new access point is highlighted in bold (active).

4. Update firmware and modem

Internet slowdowns are often due to outdated modem drivers or firmware bugs. On Redmi, modem updates come separately from major MIUI updates.

How to check and update:

1. Go to Settings → About Phone → System Update. If a new version is available, install it.
2. To force modem updates, enter the Phone code in the Phone app: ##4636## Then select Phone Information and scroll to Modem Configuration Update. If the button is active, press it.

Important for Redmi Note 10/11: In 2023, Xiaomi released a patch for the MT6833 modem (Dimensity 700) that fixed problems with connecting to Tele2 networks in roaming. If you have firmware older than MIUI 13.0.4, an update is mandatory.

5. Clear the cache and limit background apps

MIUI is known for aggressive memory optimization, but sometimes it works against the user: background apps (especially instant messengers and social networks) can eat up traffic and slow down the Internet.

• 🧹 Cache Clearing: Go to Settings → Annexes → App management, find Google Play Services and Tele2 Russia, then click Clear Cache.
• 🚫 Background Limitation: In the same menu, select Limit background activity for unnecessary apps (such as games or news widgets).
• 📵 Disabling Auto Updates: In the Play Store → Settings → Auto Update Apps Select Only via Wi-Fi.

For Redmi with 4/64GB or less: Lack of memory can lead to modem hang-ups. Regularly clear Memory via Settings → Storage or use the Clean Master app (only for cache cleanup, don’t use boosters!).

💡

If the Internet is running faster after cleaning the cache, but it slows down again after a day, install the Disable Service app and turn off background activity for Google Play Services (caution: this may disrupt some applications!).

6. Check the tariff plan and balance

Tele2 actively uses dynamic speed limit (throttling) even before the traffic is exhausted. For example, at the My Online tariff after 20 GB, the speed can drop to 64 Kbps, although the official FUP is 30 GB.

How to check the actual limit:

1. Send. USSD-request: *155*1# — Shows the remaining traffic and current speed.
2. Or use the My Tele2 app ("My rate" section).

If the speed is limited, consider changing the fare.

• 💰 "No-limit 800" - real unlimited 150 Mbit / s (but after 50 GB can slow down in prime time).
• 📶 "My online. +" — 50 GB at top speed, then 128 Kbps.
• 🌐 "Travel fare" - if you travel frequently in Russia (includes roaming without restrictions).

Lifehack for Tele2: If you have a FUP, try changing the fare to another and coming back through the app. Sometimes this resets the traffic counter (it doesn't always work, but it's checked by Redmi Note 10 Pro users).

💡

If the speed drops in the evening (18:00-23:00), the problem is not with the phone, but with the congestion of the Tele2 network.

7. Alternative acceleration methods

If standard methods don’t help, try these advanced techniques:

• 📡 Forced network selection: From the engineering menu (#4636##) select Phone Information → Set the network type and manually specify LTE only (if you have one) 4G-model).
• 🔄 Reset Network Settings: Go to Settings → System system → Resetting settings → Reset mobile network settings. Warning: this will delete all stored Wi-Fi passwords!
• 🛡️ Shutdown IPv6: In the settings APN (Type APN) add,ipv4 at the end of the line (example: default,supl,ipv4). This could speed up connection in some regions.

For root-rights Redmi: Install SignalCheck Lite to manually select the fastest base station. You can also edit /system/etc/firmware/mbn to optimize your modem (requires knowledge!).

8. Hardware problems and when to contact the service

If nothing helps, the cause may be iron:

• 📶 Damaged communication module: If the phone falls or gets wet, the antenna 4G/LTE You could have moved away. Check if the signal is lost when you tilt the device.

Cost of repair (average in Russia):

⚠️ If the Internet is completely lost after the fall of the phone (not even a phone) 2G), Don’t try to disassemble Redmi yourself – antennas 4G You can call the service with the micro-sweetening equipment.
