5G has become one of the most talked-about mobile network technologies because it can provide faster speeds, lower latency, and a better experience for supported devices. Many Android users who currently see 4G or LTE on their phone naturally wonder whether they can convert their existing 4G connection to 5G.

The answer depends on your phone, SIM card, mobile carrier, software settings, and 5G coverage in your area.

Most importantly, you cannot turn a 4G-only Android phone into a real 5G phone simply by installing an app or changing a hidden setting. A device needs compatible 5G hardware, including a supported modem and radio components, to connect to a 5G mobile network.

However, if you already have a 5G-capable Android phone and it is currently connecting to 4G, there are several things you can check to get 5G working.

In this guide, we will explain how to enable 5G on an Android phone, how to check whether your device supports 5G, what settings you should change, and what to do if 5G is not appearing.

Can You Convert a 4G Phone to 5G?

No, a normal 4G-only phone cannot be physically converted into a genuine 5G phone through software.

5G connectivity depends on hardware inside the smartphone. The phone needs a compatible cellular modem, radio components, antennas, and software support.

Changing the preferred network setting to “5G” does not add 5G hardware to a phone that was designed only for 4G.

This is an important point because many websites and applications claim to “convert 4G to 5G” with a simple app or secret code. These methods cannot turn a 4G-only device into a genuine 5G device.

If your phone already supports 5G but is currently using LTE or 4G, however, you may be able to enable or troubleshoot 5G through your network settings.

How to Check If Your Android Phone Supports 5G

Before changing any settings, the first step is to confirm whether your phone model actually supports 5G.

There are several ways to check.

Check Your Phone Model

Open:

Settings → About Phone

Look for the exact model name and model number.

Search the manufacturer’s official specifications for that model and check whether 5G is listed under mobile network connectivity.

Different versions of the same smartphone can have different network capabilities depending on the country or region, so checking the exact model is better than relying only on the phone’s marketing name.

Check the Original Specifications

You can also visit the manufacturer’s official website and search for your phone model.

Look for terms such as:

• 5G
• 5G NR
• Sub-6 GHz
• 5G network
• 5G bands

If the official specifications list only 2G, 3G, and 4G/LTE and do not mention 5G, the phone is probably a 4G-only model.

How to Enable 5G on a Compatible Android Phone

If your Android phone supports 5G, you may need to select a 5G-capable network preference.

The exact menu differs between manufacturers and Android versions.

On Google Pixel devices, for example, Google provides a network settings path through Settings → Network & internet → SIMs, where users can access the preferred network type when supported by the carrier and device.

A typical Android process is:

1. Open Settings.
2. Open Network & Internet, Connections, or Mobile Network.
3. Select your SIM card.
4. Open Preferred Network Type or a similar option.
5. Select an option containing 5G, such as 5G/LTE/3G/2G.
6. Return to the home screen.
7. Turn mobile data off and on again.
8. Wait for the phone to connect to the available network.

The names of these settings can vary by manufacturer.

Example: Samsung Galaxy Phones

On many Samsung Galaxy devices, mobile network settings are located under:

Settings → Connections → Mobile Networks

Depending on the model, carrier, and software version, you may find a Network Mode option.

If the phone supports 5G and your carrier allows it, an option containing 5G may be available.

Samsung’s support resources also provide a dedicated “How to use 5G with your Galaxy phone” topic, while available settings can vary between devices and networks.

Make Sure Your SIM and Mobile Plan Support 5G

Having a 5G phone does not automatically guarantee a 5G connection.

Your mobile carrier must also support 5G service for your SIM and plan.

If your phone is 5G-compatible but continues to show 4G, contact your network provider and ask:

• Is 5G available on my current plan?
• Does my SIM support 5G?
• Is 5G available in my location?
• Does my phone model support the carrier’s 5G network?
• Do I need to activate 5G on my account?

The carrier may also need to provision your SIM or account for 5G service.

Check 5G Coverage in Your Area

Another common reason for seeing 4G instead of 5G is simple: there may not be 5G coverage where you are.

A 5G-capable smartphone normally falls back to 4G or another available network when 5G service is unavailable. Google specifically notes that supported Pixel phones can fall back to 4G and lower networks when 5G is unavailable.

This means seeing a 4G icon does not necessarily indicate that your phone is defective.

You may simply be outside the carrier’s 5G coverage area.

Try moving to another location where your carrier provides 5G coverage and check the network indicator again.

Restart Your Android Phone

If your phone, SIM, and plan all support 5G but the connection is not appearing, a simple restart can sometimes help.

Follow these steps:

1. Turn off mobile data.
2. Turn on Airplane Mode.
3. Wait approximately 10–15 seconds.
4. Turn Airplane Mode off.
5. Turn mobile data back on.
6. Restart the phone if necessary.

This forces the device to reconnect to the mobile network.

Check for Android and Carrier Updates

Software updates can include modem, network, security, and carrier configuration improvements.

Open:

Settings → System → Software Update

The exact location varies by manufacturer.

Install available official updates and restart the phone afterward.

Avoid unofficial firmware or modified network software simply to force a 5G icon. Such modifications can cause network problems, instability, or other device issues.

Check Your Preferred Network Type

If your Android phone supports 5G, check the preferred network setting.

For many Android devices, the setting may look similar to:

Settings → Mobile Network → Preferred Network Type

Possible choices can include:

• 5G/4G/3G/2G
• 5G/LTE
• LTE/3G/2G
• Automatic
• LTE only

The exact options depend on the device and carrier.

Google also notes that available mobile network settings vary by phone and Android version.

If you see a 5G option, select the appropriate automatic or preferred 5G mode rather than forcing a network mode that your carrier does not support.

Why Is My 5G Phone Showing 4G?

There are several possible reasons.

1. 5G Is Not Available

The simplest explanation is that you are outside a 5G coverage area.

2. Your SIM or Plan Does Not Support 5G

Your carrier may require a compatible plan or SIM before allowing 5G access.

3. 5G Is Disabled in Settings

Some phones allow users to select a preferred network mode. If the phone is configured for LTE only, it may not connect to 5G.

4. Battery-Saving Features

Some devices may manage 5G usage depending on battery-saving or network settings.

Check your battery and mobile network settings if 5G frequently disappears.

5. Your Phone Variant Is Different

A smartphone with the same commercial name can have different regional variants. One model may support certain 5G bands while another may not.

6. Temporary Network Problems

Carrier maintenance, congestion, or local network issues can temporarily affect 5G availability.

Can an App Convert 4G to 5G?

No legitimate Android application can add physical 5G hardware to a 4G-only phone.

Apps may provide shortcuts to network settings, display network information, or help test your current connection, but they cannot transform a 4G modem into a 5G modem.

Be careful with applications that promise:

“Convert 4G to 5G with one click.”

Such claims are often misleading.

You should never give an unknown app unnecessary access to your phone, messages, contacts, files, or other sensitive information simply because it promises faster mobile internet.

Can a Secret Code Enable 5G?

Some Android devices have diagnostic or testing menus that display advanced network information. However, these menus do not magically add 5G capability to unsupported hardware.

If a 5G option does not appear in the normal network settings, it may be because of:

• Device limitations
• Carrier restrictions
• Regional configuration
• Unsupported 5G bands
• Software configuration
• SIM or plan limitations

Google’s support documentation also notes that available network options can differ based on the phone and carrier.

It is generally better to use the standard settings provided by your phone manufacturer and carrier instead of changing hidden engineering settings.

How to Get Faster Internet on a 4G Android Phone

If your phone does not support 5G, you can still improve your 4G experience.

Use a Stronger Signal Location

Mobile speed can change significantly depending on signal strength and network congestion.

Try using your phone near a window or in an open area.

Restart Your Network Connection

Turn Airplane Mode on for a few seconds and then turn it off.

This forces your phone to reconnect to the mobile network.

Close Heavy Background Apps

Applications using large amounts of mobile data in the background can reduce available bandwidth.

Check:

Settings → Network → Data Usage

and identify applications consuming excessive data.

Use a Suitable Mobile Plan

If your carrier offers different data plans, check whether your current package has speed restrictions or data limits.

When Should You Upgrade to a 5G Phone?

If you regularly use mobile data and 5G coverage is available in your area, upgrading to a 5G-compatible phone may make sense.

Consider upgrading when:

• Your current phone is 4G-only.
• Your carrier provides 5G in your area.
• You frequently download large files.
• You stream high-resolution video.
• You use cloud services frequently.
• You need lower network latency.
• Your current phone is already due for replacement.

You do not necessarily need the most expensive smartphone. Many affordable Android devices now offer 5G connectivity.

Important Things to Know Before Buying a 5G Phone

Do not choose a phone based only on the words “5G” printed on the box.

Check:

5G Band Compatibility

Make sure the phone supports the 5G bands used by your carrier.

Carrier Compatibility

A phone can support 5G but still have limited compatibility with a particular carrier.

SIM and eSIM Support

Check which SIM technologies the phone supports and whether your carrier supports them.

Regional Model Number

Always verify the exact model number, especially when purchasing an imported smartphone.

Frequently Asked Questions

Can I convert my old 4G phone into 5G?

No. A 4G-only smartphone cannot be converted into a genuine 5G device with an app, setting, or software update. The phone needs compatible 5G hardware.

How do I enable 5G on Android?

If your phone supports 5G, open the mobile network settings and look for a preferred network or network mode option containing 5G. The exact menu depends on your phone and carrier.

Why does my 5G phone still show 4G?

Your phone may be outside 5G coverage, your SIM or plan may not support 5G, or 5G may not be enabled for your device or account.

Do I need a new SIM for 5G?

It depends on your carrier and existing SIM. Some SIMs may already support 5G, while others may need replacement or activation. Contact your carrier for confirmation.

Is a 5G app required?

No. You do not need an app to turn a compatible Android phone’s 5G connection on. Network access is handled by the phone, modem, operating system, SIM, and carrier.

Does changing APN settings convert 4G to 5G?

No. APN settings help configure how your device connects to the carrier’s data network, but changing an APN cannot add 5G hardware to a 4G-only phone.

Final Verdict

If you are searching for how to convert 4G to 5G on an Android phone, the most important thing to understand is that there are two different situations.

If your phone is already 5G-compatible, you can check the preferred network settings, confirm that your SIM and plan support 5G, update the phone, and make sure you are in a 5G coverage area.

If your phone is 4G-only, there is no reliable software trick, application, secret code, or APN setting that can turn it into a genuine 5G smartphone. In that situation, the practical solution is to continue using 4G or upgrade to a 5G-compatible device.

For the best results, always check the exact phone model, carrier compatibility, supported 5G bands, SIM requirements, and local coverage before making a purchase or changing network settings.
