How to improve communication with Xiaomi Redmi Note 10 Pro: the full guide

Mobile internet problems or intermittent voice signal can turn a flagship smartphone into a useless piece of plastic. Owner of Xiaomi Redmi Note 10 Pro can face a situation when the room disappears 4G and calls are terminated, despite the confident coverage of neighbors.

However, the software settings of the MIUI operating system sometimes conflict with the parameters of local carriers, which leads to unstable operation of the radio module. In this article, we will discuss in detail the methods that will help you return a stable mobile Internet and high-quality voice communication.

We won’t use the dubious apps from the Play Market that promise to “boost the signal” but actually drain the battery, and all of the solutions we offer are based on deep configuration of system settings, hidden engineer menus, and proper configuration of APN access points.

Diagnostics of the current network status and signal

Before you make any changes, you need to understand the real picture of what's happening. The visual sticks in the status bar are just a rough indicator that often hides the truth. For an accurate diagnosis, you need to look at the technical menu of the phone, which displays the numerical values of the signal level.

Click on the dialer code ##4636##. You will see the hidden test menu. Select "Phone Information." Here you are interested in RSRP (signal level) and SINR (signal quality). RSRP above -90 dBm is considered excellent, from -90 to -105 dBm is good, and anything below -110 dBm indicates poor reception.

Note the SINR parameter. If it's negative or close to zero, your signal is heavily noisy by noise from other operators' towers or appliances, and even a high signal level (RSRP) would not produce high speed.

• 📡 RSRP — It shows the signal power, the closer to 0, the better.
• 📶 SINR — The ratio of signal to noise is critical for speed 4G.
• 🏗️ Cell ID — identifier of the base station to which you are connected.

⚠️ Warning: Don't change the settings in the engineering menu randomly. Write down the initial values before any experiment so you can roll back.

If the diagnostics are critically low, it makes sense to check if the phone has switched to an outdated communication standard. Sometimes the Redmi Note 10 Pro "sticks" to EDGE or 3G, ignoring the faster LTE.

Network Type Change and Forced LTE Selection

One of the common causes of the speed drop is the automatic network selection mode. The smartphone tries to find the "best" network, but in conditions of unstable coverage, it can constantly jump between the two. 3G and 4G, Breaking the connection. Forced setting of the mode LTE Only or LTE/WCDMA often solves the problem.

Go back to the menu opened with ##4636##. Find the drop-down list "Preferred network type." By default, it could be "5G/4G/3G/2G (auto)." Try switching to "LTE only" (LTE only), which will cause the modem to ignore the old towers and hold on to 4G.

However, this method has a downside: in mode"LTE Only" incoming voice calls may stop coming if your carrier does not support VoLTE or it is not activated"LTE/WCDMA/GSM (Auto” but prohibit falling below 3G, If your provider’s menu allows it.

After the change of mode, it is recommended to turn on and off the aeromode to restart the radio module, this action resets the current connection and causes the phone to re-register with the new parameters.

💡

If, after the choice"LTE Only' voice is missing, activate VoLTE in settings SIM-card or contact the operator to connect the service.

Setting up APN access points to speed up the internet

Access Point Name Access Point (APN) — These are the gateways through which your phone connects to an ISP. SIM-maps that are not optimized for modern speeds and may contain outdated gateway addresses.

To fix this, go to Settings. → SIM-maps and mobile networks → Choose yours. SIM → Access points (APN). Click the button "New access point" or "Create" APN". It is important to fill in the fields correctly to ensure stable mobile traffic.

In the "Name" field, type in any name, such as "Fast Internet"APN" (or "Access point") you need to enter your operator's data. For most Russian operators, these are standard values: Internet, mts, Internet.beeline.ru or internet.tele2.ru.

Pay special attention to the field "APN type." Make sure that it says default,supl. This will ensure the operation of the normal Internet and geolocation services. The field "APN Protocol" is better set to IPv4/IPv6, which will allow the phone to choose the best route of traffic.

After filling in all the fields, be sure to press the three dots in the corner of the screen (or menu button) and select Save. Then activate the new access point by ticking next to it. Rebooting the phone after this procedure is mandatory for the application of changes.

Resetting network settings and re-registration in the system

If manual settings didn’t help, there may have been software errors or profile conflicts in the system. MIUI has a full network reset feature that returns all modem, Wi-Fi and Bluetooth settings to factory status without affecting your personal files.

Reset via Settings → Connection & Sharing → Reset Wi-Fi, Cellular Networks and Bluetooth. Press Reset button at the bottom of the screen. The system will warn that stored Wi-Fi passwords and other Bluetooth devices will be deleted.

This method is particularly effective after upgrading the firmware or when moving to another region where the phone continues to look for towers of the previous location.

⚠️ Before resetting, make sure you remember passwords from important Wi-Fi networks, as it will be impossible to recover them from your phone’s memory after this procedure.

An alternative, more radical method is the use of USSD-commands to reset settings to factory, but in the context of communication we will limit it to a network reset, since a full data reset (Wipe Data) requires backup of all information.

Once you reboot, re-enter the APN data if it doesn't automatically pull up. Often, it's a clean login without the old "junk" in the modem cache that gives you more stability.

Using an engineering menu to fine-tune

For advanced users, the Xiaomi Redmi Note 10 Pro provides access to a deep engineering menu through the code ##3646633##. Here you can control transmitter power and frequency priorities.

Go to Telephony → Network Selecting, where you can stop your phone from using certain bands that don't work well in your area, for example, if the 1800 MHz (Band 3) tower is overloaded and the Band 8 900 MHz signal is stable, albeit slow, you can try experimenting.

Also in the Hardware Testing section → RF You can run antenna tests, but the average user should just limit themselves to BandMode. SIM-Try changing the map and changing the mode with EGSM900/DCS1800 on LTE900/1800 or similar to the ranges of your operator.

• 🔧 Band 3 (1800 MHz) – the main range for the 4G high-speed.
• 🌳 Band 20 (800 MHz) – long-range range, good for the village and indoors.
• 🏙️ Band 7 (2600 MHz) – network capacity, operates in the city center.

Remember that the antenna module in the Redmi Note 10 Pro has its own physical limitations: software amplification cannot compensate for the lack of signal in a remote basement, but it can help you choose a more stable frequency.

Hardware factors and the influence of covers

The Redmi Note 10 Pro has built-in antennas located around the perimeter of the body. Some metal cases, magnetic latch cases or thick protective glass with a metalized edge can shield the signal.

If you take off the cover and check the signal level in the same place, if the difference is significant (for example, 1-2 divisions or switching from 3G to 4G), then the accessory interferes with the antennas, and the signal is also affected by tips from powerful sources of radiation: microwave ovens, routers, transformer boxes.

In rare cases, the problem lies in the SIM-If your SIM is bigger than yours 5-7 It may not work properly with modern networks. 4G. Replacement SIM-cards for the new in the cabin operator often works wonders, even if the old visually intact.

⚠️ Warning: Do not use so-called "antenna stickers" or foil glued inside the enclosure, which disrupts the antenna's coordination and can cause the modem to overheat and fail.

It's also worth checking if the battery is critically discharged, and in energy-saving mode, the system can artificially limit the power of the transmitter to save charge, which impairs communication.

💡

The combination of APN software optimization and the absence of physical interference gives the maximum effect of improving communication.
