Learn how to enable 4G or 5G on Android in 2026, change preferred network settings, troubleshoot slow mobile data, and improve connection performance.
Is your Android phone taking too long to load websites, stream videos, or download files? A slow mobile internet connection can be frustrating, especially when you need to browse, watch videos, or use social media.
One setting worth checking is your phone’s preferred network type. Depending on your device, SIM card, mobile plan, and network coverage, switching to the appropriate 4G LTE or 5G mode may improve your connection experience.
The good news is that you usually do not need to install an extra app to check these settings. Android includes network options that let you manage how your phone connects to your carrier.
In this guide, you will learn how to enable 4G or 5G on Android in 2026, troubleshoot slow mobile data, and understand which settings can actually make a difference.
Important: Enabling 4G or 5G does not guarantee faster internet. Your actual speed depends on coverage, network congestion, your phone’s hardware, your carrier, and your mobile data plan.
What Is the Difference Between 4G and 5G?
Before changing your network settings, it helps to understand the two technologies.
4G LTE is a widely used mobile network technology that supports browsing, video streaming, online gaming, and downloads. In areas with good coverage, it can provide a reliable internet experience.
5G is a newer generation of mobile networking designed to support higher speeds and greater network capacity in suitable conditions. However, performance varies depending on the local network, signal strength, and the type of 5G deployment.
A 5G phone does not automatically receive a faster connection everywhere. If your area has weak 5G coverage, a strong 4G LTE connection may sometimes perform better.
How to Enable 4G LTE on an Android Phone
If your phone is using an older network mode or struggling to connect, check the preferred network setting.
Step 1: Open Android Settings
Unlock your phone and open the Settings app.
Look for a section called Network & Internet, Connections, or Mobile Network. The wording depends on your phone’s manufacturer and Android version.
Step 2: Select Your SIM Card
If your phone supports dual SIM cards, select the SIM card you use for mobile data.
Open the SIM or mobile network settings to view the available network options.
Step 3: Find the Preferred Network Type
Look for an option such as:
- Preferred network type
- Network mode
- Voice and data
- Preferred network
The exact options may vary by device and carrier.
Step 4: Select 4G LTE or an Equivalent Option
If your phone offers a suitable option, select 4G LTE or a network mode that includes LTE.
Some phones combine several network types into a single setting, such as 5G/4G/3G/2G automatic. If you want your phone to use available modern networks automatically, this combined mode may be appropriate.
Wait a few moments for the phone to reconnect. Then open a website or app to check whether mobile data works properly.
How to Enable 5G on Android in 2026
If you have a 5G-compatible phone and an eligible mobile plan, you can check whether 5G is enabled.
Step 1: Confirm Your Phone Supports 5G
Not every Android phone supports 5G. Check your phone’s official specifications or the manufacturer’s website to confirm that your particular model supports the required 5G bands.
A phone’s name alone may not be enough because different regional versions of the same model can have different network capabilities.
Step 2: Check Your SIM and Mobile Plan
Your carrier must support 5G for your account and location. Some carriers may require an eligible plan, a compatible SIM, or specific account settings.
Contact your mobile network provider if you are unsure whether 5G is available on your SIM.
Step 3: Open Mobile Network Settings
Go to Settings and open the mobile network section for your active data SIM.
Look for Preferred network type, Network mode, or a similar option.
Step 4: Choose a 5G-Compatible Mode
If available, select an option such as 5G/4G/3G/2G (Auto) or another mode that includes 5G.
The exact wording varies by phone and carrier. Some devices manage network selection automatically and do not provide a separate 5G toggle.
Step 5: Check the Signal Indicator
Return to your home screen and look at the status bar. If 5G coverage is available and the carrier allows the connection, your phone may display a 5G indicator.
Seeing the indicator does not guarantee a particular download speed. Run a speed test or load a few websites to check real-world performance.
What If You Cannot Find the 4G or 5G Option?
Some Android phones hide network settings or manage them through the carrier’s configuration.
Try these steps:
- Search for “Mobile Network” or “Preferred network type” in the Settings search bar.
- Check that the correct SIM card is selected for mobile data.
- Install available system updates from your phone’s official settings.
- Confirm that your phone model supports the required network technology.
- Ask your carrier whether 4G or 5G is enabled for your account.
If the network mode is controlled by your carrier, you may not be able to change it manually.
Avoid unfamiliar apps or secret codes that promise to unlock hidden 5G features. Such methods may not work on your phone and can make troubleshooting more difficult.
How to Improve Mobile Internet Speed on Android
Changing the preferred network mode is only one possible solution. If your internet remains slow, try these practical steps.
1. Move to an Area with Better Signal
Buildings, basements, walls, and other obstacles can weaken mobile signals.
Try moving near a window or to an open area. If your phone receives a stronger signal, browsing and downloads may improve.
2. Turn Airplane Mode On and Off
Airplane mode temporarily disconnects your phone from mobile networks.
Open Quick Settings, turn Airplane mode on, wait about 10 seconds, and turn it off again. Your phone will attempt to reconnect to the network.
This can resolve some temporary connection problems, although it will not fix poor coverage or network congestion.
3. Restart Your Phone
A restart can help resolve temporary software or connectivity issues.
Save any work, restart your phone, and test mobile data again once the network reconnects.
4. Check Your Data Allowance
Some mobile plans reduce speeds after you reach a certain data limit. Other plans may have fair-use restrictions or different speeds depending on the package.
Check your carrier’s app or account portal to confirm that your data allowance is still available.
5. Disable Data Saver if Necessary
Data Saver can restrict background data for certain apps. It does not necessarily reduce the maximum speed of your entire mobile connection, but it can affect how some apps behave.
If an app is not updating or loading content as expected, open your data settings and review Data Saver and app-specific data permissions.
6. Update Your Android Software
Software updates may include bug fixes and improvements to connectivity.
Open Settings and check for official system updates. Install them when appropriate, following your device manufacturer’s instructions.
7. Check for Network Congestion
Mobile internet can become slower when many people use the same cell tower, especially during busy hours or large public events.
If speeds improve at another time or location, congestion may be the cause. Changing your phone’s network setting cannot always solve this issue.
Should You Force Your Phone to Use 5G Only?
In most cases, using an automatic network mode is the more practical choice.
A 5G-only setting, if your phone offers one, may prevent the device from falling back to 4G in areas where 5G coverage is weak or unavailable. This can cause dropped connections or unreliable mobile data.
Automatic network selection lets the phone use supported networks according to its settings and the carrier’s configuration.
If you are testing network performance, compare 4G and 5G in the same location under similar conditions rather than assuming 5G will always be faster.
Does 5G Use More Battery Than 4G?
Battery consumption depends on the phone, signal conditions, network activity, and how the carrier’s 5G network operates.
In some situations, searching for a weak 5G signal may use additional power. In other situations, 5G may handle data transfers efficiently.
If battery life matters more to you than peak speed and your phone has a 4G-only option, you can compare battery performance with both settings. However, the result will vary from device to device.
Why Is My 5G Phone Still Using 4G?
There are several possible reasons:
- 5G coverage is unavailable in your current location.
- Your phone does not support the local 5G bands.
- Your mobile plan or carrier account does not have 5G access.
- Your preferred network setting does not include 5G.
- The phone has temporarily switched to 4G because of signal conditions.
- Your carrier manages network selection automatically.
Check your device specifications, plan eligibility, and coverage before assuming your phone is faulty.
Final Words
Enabling the right 4G or 5G network setting can help your Android phone use the mobile network available to it. Start by checking your preferred network type, selecting the correct data SIM, and confirming that your phone and plan support the technology you want to use.
If your connection is still slow, try improving signal reception, restarting your phone, checking your data allowance, and testing the network in another location.
Remember that there is no single setting that guarantees instant internet speed. The best results come from using a compatible device, a suitable mobile plan, and reliable network coverage.
