Xiaomi Redmi 8 is a popular budget smartphone released in 2019, but many users still wonder if it supports fifth-generation networks and how to activate them. The answer is not as clear as it might seem. In this article, we will examine the technical limitations of the model, alternative ways to improve Internet speed and give clear instructions for those who still want to try to “overclock” their device.
Let me warn you right away: Redmi 8 doesn’t officially support 5G due to hardware constraints. However, there are workarounds, from optimizing current 4G networks to experimenting with firmware. We’ve analyzed all the available methods, including risks and consequences, so you can make an informed decision. If your goal is maximum mobile internet speed, it may be worth considering upgrading to a newer Xiaomi model (such as the Redmi Note 11 Pro 5G or POCO X5 5G).
Redmi 8: Why is there no 5G?
The main reason Redmi 8 doesn't support 5G is because of the hardware, and let's look at the key components that define the network's capabilities:
- 📱 Processor: Qualcomm Snapdragon 439 – budget chipset 2018, which does not have a built-in 5G-It only supports the network to the LTE Cat. 4 (maximum 150 Mbps).
- 📡 Modem: Built into the processor X6 LTE not compatible with frequencies 5G (for example, n78 or n41, Russian-made).
- 📶 Antennas: The design of the Redmi 8 does not provide additional antennas for the MIMO 5G, What is critical for a stable signal.
- 🔄 Firmware: Even custom versions MIUI LineageOS can’t add support 5G hardware-level.
For comparison, modern 5G smartphones (such as the Redmi Note 12 Pro+ 5G) are equipped with Snapdragon 7xx/8xx or Dimensity processors from MediaTek, where the X55, X60 or M70 modems support all current ranges. In Redmi 8, upgrades to 5G are possible only by completely replacing the motherboard - which is economically impractical.
What to do instead of 5G: alternatives to speed up the Internet
If your goal is to increase mobile internet speed, you don’t have to chase 5G. Here are some real-world ways to optimize Redmi 8 for maximum performance on 4G/LTE networks:
- Activate VoLTE and VoWiFi These technologies improve the quality of communication and stability of the Internet during calls. → SIM-maps and mobile networks → [Yours. SIM] → Turn on VoLTE/VoWiFi.
- Use the LTE Band 3/7/20 bands in Russia, the most stable frequencies are 1800 MHz (Band 3) and 800 MHz (Band 20).
- Turn off automatic network selection Sometimes the smartphone clings to congested base stations. Manually select the operator in Settings → Mobile Network → Network Operators → Manual selection.
- Update the software and modem The latest versions of MIUI (e.g. MIUI 12.5) optimize networking. Check for updates in Settings → About Phone → System Update.
It is also worth checking the quality. SIM-Old cards (issued before) 2018 may limit the speed of up to 3G. Contact the operator for a free replacement USIM or 4G/LTE-map.
💡
If you use mobile internet frequently, install NetMonster or Network Cell Info from Google Play, which shows real-time connection speeds, signal strengths and frequencies used.
Step-by-step: how to turn on "pseudo-5G" on Redmi 8
While real 5G on Redmi 8 is impossible, you can simulate its display in the status bar (e.g., replacing the 4G icon with 5G). It's a purely cosmetic trick, but some users find it useful. Here's how to do it:
Make a backup copy of the data
Charge your phone at least 50%
Install a file manager (e.g., MiXplorer)
Download the archive with icons (link in spoiler)-->
- Get root rights without them to change system files is impossible. Use Magisk or TWRP to unlock the bootloader and install the superuser. How to unlock the bootloader on Xiaomi?The process takes 7-14 days due to Xiaomi policy. You need to link the Mi Account to the device, apply for unlocking through Mi Unlock Tool and wait for SMS-confirmation. Detailed instructions on the official Xiaomi website.
- Edit system files with MiXplorer go down the path /system/media/theme/default/icom and find the files: stat_sys_data_fully_connected_4g.png stat_sys_signal_strength_4g.png Replace them with downloaded icons with an inscription 5G (can be found on the forums 4PDA or XDA-Developers).
- Reboot the device After replacing files, execute the command in Terminal Emulator: su chmod 644 /system/media/theme/default/icom/stat_sys_*.png reboot
Note: This method does not speed up the Internet or add support 5G-It only changes the icon displayed, which can be misleading to other users or applications (for example, speed tests).
Engineering menu: fine-tuning 4G/LTE networks
The hidden engineering menu allows you to manually configure mobile network settings, including priority frequencies and modem modem modems. This won't include 5G, but will help maximize 4G speeds.
To open the menu:
- Enter the phone code in the app: ##4636##.
- Select the item Phone Information.
- Scroll down to the Network Type Installation block.
Recommended settings for Russia (operators MTS, Beeline, MegaFon, Tele2):
| Parameter | Recommended value | Explanation |
|---|---|---|
| Set preferred network type | LTE only | Disables automatic switching to 3G/2G, which speeds up the connection to 4G. |
| LTE Band | 3, 7, 20 | The main 4G bands in Russia. the Band 20 (800 MHz) is better at penetrating buildings. |
| VoLTE | Enabled | Allows you to call LTE without falling internet speed. |
| CA (Carrier Aggregation) | Enabled | Brings together a few LTE-speed-up. |
⚠️ Note: Incorrect settings in the engineering menu can lead to network loss or modem overheating. If the signal is lost after the changes, reset the network settings in Settings → System system → Resetting settings → Resetting mobile network settings.
Frequent problems and their solutions
Redmi 8 users often have difficulty trying to turn on 5G. Let's look at common errors and how to fix them:
- 🔴 "No Network after Changes to Engineering Menu Reason: Incorrectly Specified Ranges LTE. Solution: Return settings to factory or select Auto in Set preferred network type.
- 🔴 Badge 5G The reason is that it's just a visual trick (see section above). Solution: don't expect real acceleration, optimize. 4G manually.
- 🔴 Phone overheats when Internet is used heavily Reason: weak Snapdragon 439 processor can not cope with the load.Solution: disable background application activity in Settings → Battery → Optimizing the battery.
- 🔴 The operator does not provide 5G The reason for this is that even if the Redmi 8 was supported by the 5G, Solution: Check the coverage map on the operator's website.
If the Internet speed is low after all the manipulations, the problem may be:
- 📶 Overloaded base station (especially during rush hour).
- 📱 Limit the traffic from the operator (check in your personal account).
- 🔋 Battery savings (turn off in Settings) → Battery → Performance mode).
💡
If you're Redmi. 8 suddenly stopped catching the network after experimenting with settings, the most likely cause is a failure in the file nv_data.bin (The modem configuration manager can only be restored through the firmware of the full stock software in mode. EDL (emergency loading).
Should I upgrade to a 5G smartphone?
If you're critically interested in mobile Internet speed, you'll have to think about changing your device sooner or later, and here are some objective criteria to help you make your decision:
| Criteria | Redmi 8 (4G) | Modern. 5G-Smartphone (for example, Redmi Note 12 Pro)+) |
|---|---|---|
| Maximum download speed | up to 150 Mbps | Up to 3 Gbps (under ideal conditions) |
| Delay (ping) | 30-50 ms. | 10-20 ms. |
| Support for modern standards | LTE Cat. 4, no VoNR | 5G SA/NSA, VoNR, Wi-Fi 6 |
| Price (b/y) | 3 000–5 000 ₽ | 15 000–25 000 ₽ |
It makes sense to update if:
- 📊 You often download large files (such as games or videos) 4K).
- 🎮 Play online games where low latency is important (PUBG Mobile, Call of Duty).
- 🏙️ You live in a city with a developed 5G-infrastructure (Moscow, St. Petersburg, Kazan, etc.).
- 🔄 You plan to use your phone longer. 1-2 years (4G-The devices are gradually losing support).
If you use the Internet mainly for social networks, instant messengers and watching videos in the Internet 720p, Redmi 8 The main thing is to keep an eye on the battery (its capacity is through the 3-4 year of operation falls 30-40%).
