You cannot physically convert a 4G-only smartphone into a 5G phone using an app or software setting. A device needs compatible 5G hardware, modem support, antennas, and a supported network to connect to 5G.
However, if your Android phone already supports 5G but is currently connected to 4G/LTE, you may be able to enable 5G through the network settings. This is often what people mean when they search for how to convert 4G to 5G.
In this guide, we’ll explain how to check your phone, enable 5G, troubleshoot connection problems, and avoid misleading apps that claim to upgrade 4G hardware to 5G.
What Is the Difference Between 4G and 5G?
4G and 5G are generations of mobile network technology. 5G is designed to provide higher potential speeds, lower latency, and greater network capacity than previous generations.
The actual experience depends on several factors, including your smartphone, carrier, coverage, network congestion, spectrum, and location.
A 5G connection does not automatically mean unlimited high-speed internet. Your mobile plan and network provider also determine what services and speeds are available.
How to Check if Your Android Phone Supports 5G
Before changing any settings, first determine whether your smartphone actually has 5G hardware.
Method 1: Check Phone Specifications
Search for your exact phone model on the manufacturer’s official website and look for 5G, 5G NR, or supported 5G bands in the network specifications.
Method 2: Check Android Settings
On many Android phones, open:
Settings → About Phone → Model / Network Information
The exact options vary between manufacturers.
Method 3: Check the Mobile Network Menu
Go to:
Settings → SIM Card & Mobile Network → Preferred Network Type
If your device supports 5G, you may see options such as:
- 5G/4G/3G/2G Auto
- 5G Preferred
- 5G/4G Auto
- LTE/3G/2G
If no 5G option exists, your phone may not support 5G, although menu availability can also depend on the manufacturer, software version, SIM, and carrier.
How to Enable 5G on an Android Phone
If your phone has 5G hardware and your network supports it, enabling 5G is usually straightforward.
Step 1: Open Settings
Launch the Settings application on your Android phone.
Step 2: Open Mobile Network Settings
Look for SIMs, Mobile Network, Connections, or Network & Internet.
Step 3: Select Your SIM
If your phone has two SIM cards, select the SIM you use for mobile data.
Step 4: Open Preferred Network Type
Find the Preferred Network Type or Network Mode option.
Step 5: Select a 5G Option
Choose an option similar to:
5G/4G/3G/2G Auto
Your phone can then automatically select an available compatible network.
Menu names differ between Samsung, Xiaomi, Redmi, Oppo, Vivo, Realme, OnePlus, Motorola, Google Pixel, and other Android devices.
Does a 5G SIM Make a 4G Phone 5G?
No. A 5G-compatible SIM or mobile plan cannot add 5G hardware to a smartphone that only supports 4G.
Think of the requirements as three main components:
5G Phone + Supported SIM/Plan + 5G Coverage = 5G Connection
If the smartphone lacks a 5G modem, changing the SIM or installing an application cannot turn its hardware into 5G.
Can an App Convert 4G to 5G?
No legitimate Android app can physically upgrade a 4G-only phone’s modem to 5G.
Some applications provide shortcuts to network settings or display information about your current connection. Others may claim to “convert 4G to 5G” with a single tap.
Users should be careful with such claims. Software can sometimes change available settings on a compatible device, but it cannot add missing 5G radio hardware.
If an application asks for unnecessary permissions or promises unlimited 5G internet without a compatible network, treat the claim with caution.
Why Is My 5G Phone Still Showing 4G?
Even if your phone supports 5G, it may display 4G or LTE for several legitimate reasons.
No 5G Coverage
Your current location may not have an available 5G signal.
Network Congestion
The carrier may manage network connections depending on traffic and capacity.
5G Is Disabled
Check your preferred network mode and make sure a 5G option is selected.
SIM or Plan Limitations
Your carrier may require a compatible plan or SIM configuration for 5G service.
Battery-Saving Settings
Some devices may manage network connectivity differently when power-saving features are enabled.
Unsupported 5G Band
A phone can support 5G but still lack compatibility with particular frequency bands used in a specific region.
How to Troubleshoot 5G Connection Problems
If your compatible Android phone isn’t connecting to 5G, try these basic steps:
- Turn Airplane Mode on for a few seconds and then turn it off.
- Restart your smartphone.
- Check that 5G is enabled in Network Settings.
- Confirm that your mobile plan supports 5G.
- Move to an area with known 5G coverage.
- Install available system updates.
- Check whether your carrier has any service restrictions.
- Contact your network provider if the problem continues.
Avoid changing advanced network settings unless you understand what they do.
4G vs 5G: Quick Comparison
| Feature | 4G LTE | 5G |
|---|---|---|
| Generation | Fourth | Fifth |
| Typical Latency | Higher | Potentially Lower |
| Network Capacity | High | Higher |
| Compatible Hardware | 4G modem | 5G modem required |
| Coverage | Broad | Depends on location |
| Upgrade by App | Not applicable | Not applicable |
Actual speeds and latency vary significantly according to network conditions and the service provider.
Frequently Asked Questions
How do I convert my 4G phone to 5G?
You cannot convert a 4G-only phone into a 5G device through software. If your phone already has 5G hardware, enable 5G from its mobile network settings and make sure your carrier provides compatible 5G service.
Can I use an app to activate 5G?
An app cannot add 5G hardware to a 4G-only phone. Some apps may provide shortcuts to network settings, but they cannot upgrade the phone’s modem.
Do I need a 5G SIM?
Depending on the carrier, you may need a compatible SIM and 5G-enabled plan. Check with your network provider for the exact requirements.
Why does my 5G phone show 4G?
Your phone may be outside 5G coverage, have 5G disabled, use an unsupported network band, or have a plan or SIM that doesn’t provide 5G service.
Is 5G faster than 4G?
5G is designed to support higher speeds and lower latency than 4G, but real-world performance depends on coverage, spectrum, network congestion, device capabilities, and your carrier.
Final Verdict
Searching for how to convert 4G to 5G can be confusing because many websites and apps suggest that a simple software trick can transform any 4G smartphone into a 5G device. That’s not technically possible.
If your phone is 5G-compatible, you can usually enable the appropriate network mode, use a supported SIM and plan, and connect in an area with 5G coverage. If your phone is genuinely 4G-only, the practical way to access 5G is to use a smartphone with built-in 5G hardware.
For the best experience, always check your phone’s official specifications and your carrier’s 5G requirements rather than relying on apps that promise a one-click 4G-to-5G conversion.
