Introduction:
Mobile networks operate on multiple technologies, including 2G, 3G, 4G LTE, and 5G. While newer technologies like LTE (Long-Term Evolution) and 5G offer faster data speeds and better connectivity, mobile carriers often switch users between different network bands (2G/3G/4G/5G) based on signal strength, congestion, or compatibility. However, in some cases, users may want to force their device to stay on LTE (4G) or 5G-only mode to ensure a stable and high-speed internet connection. This is particularly useful in areas with weak 3G signals or where LTE/5G provides better network performance.
Why Force LTE (4G/5G) Mode?
There are several reasons why users prefer to lock their devices to LTE or 5G networks:
- Better Speed & Stability – LTE and 5G offer significantly higher data speeds compared to older networks like 2G and 3G.
- VoLTE (Voice over LTE) Benefits – Many carriers are shutting down 3G networks, making VoLTE a necessity for uninterrupted calls.
- Avoid Network Downgrades – In some areas, mobile networks automatically switch to 2G or 3G, leading to poor call quality and slow internet speeds.
- Improved Battery Efficiency – Frequent network switching between 3G and LTE can drain battery life faster.
- Better Online Gaming & Streaming – LTE and 5G provide low latency and consistent speeds, crucial for streaming and gaming.
How to Force LTE (4G) or 5G Only Mode
Different devices and operating systems require different methods to lock onto LTE or 5G-only mode.
For Android Users
Most Android phones allow users to tweak network settings manually. Here’s how you can do it:
Method 1: Using Phone Settings (Standard Way)
- Go to Settings.
- Navigate to Mobile Networks > Preferred Network Type.
- Select LTE Only or 5G Only, if available.
However, some phones may not provide a direct option to force LTE-only mode. In such cases, you can use a secret dialer code.
Method 2: Using Secret Dialer Code
- Open the phone dialer.
- Dial
*#*#4636#*#*(On some phones, this may not work due to carrier restrictions). - Tap Phone Information.
- Scroll down to Set Preferred Network Type.
- Select LTE Only or NR Only (5G Only) from the list.
If the code does not work, you may need to use third-party apps.
Method 3: Using Third-Party Apps
Apps like Force LTE Only (4G/5G) available on the Google Play Store allow users to switch to LTE-only or 5G-only mode even if their phone’s default settings don’t support it.
For iPhone Users
Apple restricts access to network settings, making it harder to force LTE or 5G. However, you can try:
- Standard Method (For Some Models & Carriers)
- Go to Settings > Cellular > Cellular Data Options.
- Select Voice & Data and choose LTE or 5G On.
- Using a SIM PIN Trick (Workaround for Some Users)
- Insert your SIM into an Android device.
- Force LTE-only mode using the secret code or an app.
- Reinsert the SIM into your iPhone, and it may retain the LTE/5G setting.
Potential Drawbacks of Forcing LTE or 5G Only Mode
While forcing LTE or 5G can improve speed and stability, it comes with some drawbacks:
- No 2G/3G Backup – If LTE or 5G signals weaken, calls or data may drop since the phone won’t switch to lower networks.
- Limited Compatibility – Some carriers block LTE-only settings, making it difficult to apply the changes.
- Higher Battery Consumption in Weak Signal Areas – If LTE or 5G coverage is weak, the phone may consume more power trying to maintain the connection.
- VoLTE Dependency – If your carrier does not support VoLTE, you may not be able to make or receive calls in LTE-only mode.
Conclusion
Forcing LTE or 5G-only mode can be beneficial for users looking for better speed, stable connections, and improved VoLTE call quality. However, it should be used with caution, considering network coverage and carrier restrictions. If you experience connectivity issues after forcing LTE/5G, it’s recommended to revert to automatic network selection.
