Android LTE Band Selection: A Comprehensive Guide

LTE (Long-Term Evolution) is the standard for high-speed mobile data connections, but the actual speeds and network performance can vary depending on the LTE band your phone uses. LTE bands refer to specific frequency ranges that carriers use for their networks. Different regions and carriers use different LTE bands, and some Android phones allow users to select or switch between these bands to improve connectivity or optimize performance.

This guide explains what LTE bands are, how to select LTE bands on Android, and why understanding band selection is important for your device’s performance.

What Are LTE Bands?

LTE bands are frequency ranges used by mobile carriers to provide 4G LTE connectivity. These frequency bands are often represented by numbers (e.g., Band 1, Band 3, Band 7, etc.), and each band is designated for use in specific regions or countries.

Carrier Frequency: LTE bands operate on different frequencies, typically measured in MHz (megahertz). A phone needs to support the same LTE bands that a carrier uses in order to connect to that network.
Global Variability: Different carriers in different parts of the world may use different bands. For example, Band 3 (1800 MHz) is commonly used in Europe, while Band 4 (1700/2100 MHz) is popular in North America.
Faster Data Speeds: Some LTE bands support faster speeds than others, depending on factors like bandwidth (the number of available MHz) and carrier aggregation (combining multiple bands to increase speed).

Why Is LTE Band Selection Important?

Optimizing Network Performance: Not all LTE bands are created equal. Some bands provide better coverage or faster speeds, depending on your location. Band selection allows you to choose the most suitable band for your area.
Improving Signal Strength: If you're in an area with weak coverage, manually selecting an LTE band may help you connect to a stronger signal, avoiding dropped calls or slower data speeds.
Compatibility: Some phones only support certain bands, so band selection is crucial if you're traveling to a region where different bands are in use.
Network Bandwidth: Some carriers use carrier aggregation (combining multiple bands for faster speeds), and knowing how to select those bands can significantly improve your mobile data experience.

How to Check LTE Band Support on Android

Before you begin selecting LTE bands, it's important to know which bands your device supports. Here's how to check:

Check Your Device’s Specifications:
- Look at the specifications of your phone to find a list of supported LTE bands. You can find this information on the official website or in the user manual.
Use a Field Test Mode:
- Android devices have a Field Test Mode that can show you detailed information about the LTE bands your device is connected to.
- To access Field Test Mode:
  - Open the dialer app and enter *#*#4636#*#*.
  - This will open a hidden menu where you can view your device’s network information, including LTE bands and signal strength.
  - Check the Band field to see the band your phone is connected to.
Use Third-Party Apps:
- Some apps, like Network Signal Info or OpenSignal, can display detailed information about your LTE connection, including supported bands and signal strength.

How to Manually Select LTE Bands on Android

Manually selecting LTE bands can be helpful when you're in an area with weak signal or network congestion. However, it’s important to note that not all Android devices allow manual band selection, and rooting your device (modifying its system software) might be necessary for some advanced band selection features.

Here’s how to select LTE bands on Android:

Method 1: Using Developer Options (Without Rooting)

Some Android phones allow you to select LTE bands through Developer Options, a hidden menu in Android's settings.

Enable Developer Options:
- Go to Settings > About Phone > Tap Build number 7 times to unlock Developer Options.
Access Developer Options:
- Go back to Settings and select System > Developer Options.
Select Network Type:
- Under Developer Options, look for Select Network Type or Mobile Network Type.
- This option allows you to select a preferred network mode (e.g., LTE only, 4G/3G/2G auto, etc.).
Choose LTE Band (if available):
- Some devices may allow you to choose a specific LTE band (for example, Band 3 or Band 7). If this option is available, you can select the LTE band for your current location or carrier.

Method 2: Using the Engineering Mode (Requires Root)

Some Android phones, especially Samsung and Huawei, allow access to Engineering Mode, which gives you deeper access to radio settings and LTE band management.

Access Engineering Mode:
- To enter Engineering Mode, you need to dial a special code specific to your phone model. For example, on many Huawei phones, you can dial *#*#2846579#*#* to enter the Engineering Mode.
Change LTE Bands:
- Once inside Engineering Mode, you should see options to select the LTE band or radio settings. Select the band you want to use (e.g., Band 1, Band 3, etc.) and apply the settings.
Note: This method requires rooting your Android device, which may void your warranty or cause other issues. Rooting should be done with caution.

Method 3: Using Third-Party Apps

Some third-party apps like LTE Discovery or Network Signal Guru allow you to view and sometimes select LTE bands. These apps are useful for band monitoring and may help you choose the best band for your current location.

Common LTE Bands and Their Uses

Here are some of the most common LTE bands used by carriers across different regions:

LTE Band	Frequency (MHz)	Region	Common Use
Band 1	2100 MHz	Global	Common for Europe, Asia, and Africa. Used by many carriers worldwide for 4G LTE.
Band 3	1800 MHz	Global	Popular band in Europe, Asia, and Africa. Used for high-speed data.
Band 7	2600 MHz	Global	Used in Europe, Asia, and Africa for fast data speeds.
Band 4	1700/2100 MHz	North America	Widely used by T-Mobile and AT&T in the US.
Band 13	700 MHz	North America	Used by Verizon in the US for 4G LTE.
Band 28	700 MHz	Australia, Asia	Common in Australia and parts of Asia.
Band 38	2600 MHz	Global	Used by many carriers globally for faster data speeds.
Band 20	800 MHz	Europe	Used widely in Europe for providing strong LTE coverage in rural areas.

Why Choose LTE Band Selection?

Better Coverage: Selecting a band that is widely used and supported in your region can improve signal strength, especially in areas with poor coverage.
Faster Speeds: Certain bands provide higher bandwidth, allowing for faster download speeds and better streaming quality.
Battery Life: In some cases, selecting a specific band may reduce battery consumption if the phone doesn't have to search for stronger bands.

Conclusion

LTE band selection is an important aspect of optimizing your Android phone’s mobile network performance. By understanding and selecting the right LTE band, you can improve signal strength, get faster data speeds, and ensure better coverage. While most Android devices will automatically select the best band based on your location, manual band selection can be helpful in areas with weak signals or specific network configurations.

Whether you're traveling abroad or trying to improve your signal strength in a specific area, knowing how to select the right LTE band can enhance your mobile experience.
