The emergence of the fifth generation of cellular communications 5G has become a revolutionary step in the world of mobile communications, promising users unprecedented data transfer speeds and minimal delays. However, many owners of modern Androidsmartphones are faced with the fact that their device continues to work on 4G or LTE networks by default, ignoring the faster standard. This may be due to operating system settings, manufacturer firmware features, or lack of coverage in a particular region.
Activating the fifth generation mode requires fulfilling a number of conditions that go beyond simply switching the toggle switch in the menu. You need to make sure that the device is technically capable, has an appropriate SIM card, and is supported by the mobile operator. In this article, we will analyze each setup step in detail so that you can make the most of the potential of your gadget.
Checking the technical compatibility of the device
Before delving into the software settings, it is critical to make sure that your hardware is physically capable of supporting the new communication standard. Not all smartphones released even in the last couple of years are equipped with the necessary radio modules. Manufacturers often divide their lines into models with 5G support and budget versions that work only with 4G LTE.
You can check the presence of a modem through the technical specifications on the manufacturer’s official website or in specialized applications. Pay attention to the list of supported frequencies and standards in the documentation for Samsung Galaxy, Xiaomi or Google Pixel. If the specifications do not mention NR (New Radio) or bands n1, n78, n79, then software activation is not possible.
It is also worth considering the regional features of the release. The same phone model intended for the US or Chinese market may have a different set of frequencies compared to the European version. Lack of support for specific frequencies of your operator in the region where you live will make connecting to 5G impossible, even if the phone technically supports the standard in other countries.
⚠️ Attention: Make sure that the SIM card you purchase also supports the new standard. Old cards issued several years ago may not have a profile for working in fifth generation networks, and they will need to be replaced at the operator's showroom.
Setting the preferred network type in the menu
If your device is fully compatible, the next step will be to correctly configure the network settings in the operating system Android. By default, many manufacturers set the mode to "Auto", which may mistakenly prioritize 4G stability over 5G speed, especially if the signal of the new standard is unstable.
To manually select, you need to go to the connection settings. The path may vary slightly depending on the shell, but the general algorithm remains the same for most devices. You need to find the section responsible for managing mobile networks and change the connection priority.
Follow these steps:
- 📱 Open the application
Settingson your smartphone. - 📡 Go to the section
ConnectionsorNetwork and Internet. - 📶 Select item
Mobile networkorSIM cards and mobile networks. - ⚙️ Find the line
Network modeorPreferred network type. - 🚀 In the list that opens, select the option marked 5G/LTE/3G/2G (auto).
After selecting the appropriate item, the phone will begin scanning the airwaves for available ones fifth generation towers. If there is coverage in your area, the network icon in the status bar will change from 4G or LTE to 5G, 5G+ or 5G UW depending on the operator.
If the 5G icon does not appear after a reboot, try turning on airplane mode for a few seconds, and then turn it off. This will force the modem to re-register on the network.
Setting features for different manufacturers
The shell interfaces One UI, MIUI, ColorOS and “clean” Android have significant differences in the location of menu items. Understanding these nuances will save you time when searching for the right option. Below is a table with paths to settings for popular brands.
| Brand / Shell | Path to settings | Item name |
|---|---|---|
| Samsung (One UI) | Settings → Connections → Mobile networks | Network mode |
| Xiaomi (MIUI/HyperOS) | Settings → SIM cards and mobile networks → SIM selection | Preferred network type |
| Google Pixel | Settings → Network and Internet → SIM cards | Preferred type networks |
| Realme / OPPO | Settings → Mobile network → SIM selection | Preferred network |
In some cases, especially on devices of Chinese brands with global firmware, the network selection item may be hidden. This is done to simplify the interface, but deprives the user of flexibility. If you do not find the desired option in the standard menu, you may need to use the engineering menu or third-party utilities, although this is not recommended for ordinary users.
For owners iPhone the situation is different, since iOS has its own power and network management algorithms, but in the context Android we are considering the customization opportunities provided by this platform. Always check if your phone's software is updated to the latest version, as manufacturers often add support for new frequency bands through security updates.
☑️ Checking network settings
Using the engineering menu for forced activation
If the standard settings do not produce results, advanced users can use the engineering menu Android. This hidden section allows you to manage radio module parameters at a deeper level. It is accessed by typing a special combination of characters in the Phone application.
Enter the code ##4636## in the dialer. If the code worked, the service menu will open. Select item Phone information. Here you will find the “Set your preferred network type” drop-down list. You need to select a value containing NR (for example, NR/LTE/GSM/WCDMA).
⚠️ Attention: Changing settings in the engineering menu can lead to unstable communication or complete loss of signal. Write down the original parameter values before making any changes in order to be able to roll back the settings.
It is worth noting that on many modern smartphones this code is blocked by the manufacturer or telecom operator. In this case, trying to enter the code will not lead to any result, and the menu will not open. This is a security measure to prevent inexperienced users from accidentally breaking the modem software.
What to do if the code does not work?
If the standard code does not open the menu, try codes specific to your processor. For MediaTek the code often works ##3646633##, and for Snapdragon devices you may need superuser rights (Root) and install the Engineering Mode Shortcut application. However, obtaining root access voids the guarantee.
The influence of the operator and tariff plan on speed
Even with an ideal phone setup and the presence of a powerful modem, access to the fifth generation network is regulated by your mobile operator. Enabling 5G often requires not only technical capability, but also an active connection to the service on the provider’s side.
Many operators are introducing the new standard in stages, limiting access to it for old tariff plans. You may need to upgrade to a new plan or pay for an additional 5G Access option. In addition, in some regions, coverage is hybrid (NSA - Non-Standalone), where 5G only works in conjunction with the 4G network core.
- 📞 Call your operator's support service to clarify the availability of 5G in your city.
- 💳 Check your personal account for the necessary options or restrictions on speed.
- 📍 Make sure you are in an area with good reception, as the 5G signal penetrates walls worse than 4G.
Sometimes the problem lies in the SIM card itself. If you use a card cut from an old mini or micro SIM with scissors, the contact may be broken or the chip may not support new authentication protocols. Replacing the card with a fresh USIM in a communication store often solves the problem instantly.
Successful connection to 5G depends on three factors: a compatible smartphone, correct network mode settings and an active tariff that supports the standard from your operator.
Diagnosis of problems and ways to fix them
Situations when the phone sees the network, but does not connect to it, or the speed remains low, occur quite often. For diagnostics, you can use built-in tools or third-party applications that display detailed information about the connection.
Try resetting your network settings to factory settings. This action will delete saved access points APN, Wi-Fi passwords and Bluetooth settings, but often resolves software conflicts. The reset path is usually located in the section System → Reset settings → Reset Wi-Fi, mobile data and Bluetooth settings.
If the problem persists, check if the power saving mode is enabled. Aggressive battery saving algorithms can disable the 5G module to extend device operating time. Turn off Energy Saver mode and check the result. Also make sure your phone has the latest security updates, as they often contain radio patches.
⚠️ Attention: Terms of service, coverage availability, and pricing plans are constantly changing. It's best to check the latest information about 5G availability in your specific home or office on your operator's official coverage map or through its mobile app.
Frequently Asked Questions
Why does the 5G icon appear and disappear?
This normal behavior in areas of unstable coverage. The phone automatically switches to 4G when the 5G signal becomes too weak to maintain a connection, so as not to interrupt the call. This can also happen when the network load is high.
Does turning on 5G affect battery consumption?
Yes, the 5G module consumes more power, especially when searching for a network or transferring large amounts of data. However, modern processors and modems are becoming increasingly energy efficient, so the difference in battery life on new smartphones is often unnoticeable in everyday use.
Is it possible to enable 5G on a phone that does not support it?
No, this is physically impossible. Support for the standard is determined by the presence of a special modem and antennas inside the device. Software updates cannot add hardware support where there is none.
Do you need a new SIM card to work in 5G?
In most cases, yes. Operators are demanding the replacement of old SIM cards with new USIM standards that support improved encryption and authentication algorithms necessary for secure operation in fifth-generation networks.
Will 5G work in roaming?
It depends on the agreements between your home operator and the operator in your host country. The 5G international roaming service is not available everywhere and often requires preliminary connection and checking the tariff.
