Samsung Galaxy Devices - How To Unlock Network Bands Selection Settings (New Method 2023)

Samsung Galaxy smartphones offer some of the most powerful connectivity features among Android devices. However, one of the lesser-known advanced settings—the network band selection menu—remains locked by default for most users. This setting allows users to manually select specific LTE, 5G, and 3G/2G bands, which can significantly improve signal strength, network speed, and battery performance in certain areas.

In 2023, a new method has surfaced that lets users easily unlock the network band selection settings on Samsung Galaxy devices—without root and without complex tools. This guide will walk you through everything you need to know, from understanding what network bands are to unlocking the menu and using it safely.

📡 What Are Network Bands?

Mobile networks operate across multiple frequency bands. Each band refers to a specific frequency range that carriers use to transmit signals. For example:

  • Band 1 (2100 MHz) – Common for 3G/4G

  • Band 3 (1800 MHz) – Popular LTE band

  • Band 40 (2300 MHz) – Used by Indian carriers for 4G

  • n78 (3500 MHz) – A major 5G band

Samsung phones automatically switch between available bands, but manual band selection can help when:

  • You're in a location with weak automatic signal

  • Your carrier supports multiple bands and you want the fastest one

  • You want to disable weaker or congested bands

⚠️ Why Is the Band Selection Menu Hidden?

Samsung restricts access to band selection settings to avoid user errors that could disrupt connectivity. Carriers also request such settings remain hidden to maintain consistent service across regions.

However, in many cases, manual access does no harm and can improve your experience, especially if you're tech-savvy and know what you're doing.

🧠 Benefits of Unlocking Band Selection

Before jumping into the how-to, let’s look at some real advantages:

  • ✅ Force strongest LTE or 5G bands

  • ✅ Avoid poor 3G/2G fallback

  • ✅ Extend battery life (avoiding signal switching)

  • ✅ Improve VoLTE & VoWiFi performance

  • ✅ Use global SIMs in travel scenarios

🔓 New 2023 Method to Unlock Network Band Selection on Samsung Devices

🧰 Requirements:

  • Samsung Galaxy device (Android 10 to Android 13 supported)

  • No root access needed

  • One of the following apps:

    • Samsung Band Selection (free from third-party app stores)

    • Network Signal Guru (for more detailed testing, root may be required for some features)

    • Phone Info Samsung

Let’s begin with the simplest and safest method using a dialer code and the Samsung Band Selection app.

📲 Step-by-Step Guide: Unlocking Band Selection

✅ Step 1: Enable Developer Options

  1. Go to Settings > About phone > Software information

  2. Tap Build number 7 times until you see "Developer mode enabled"

✅ Step 2: Download the Samsung Band Selection App

  1. Visit third-party app store like APKMirror or APKPure

  2. Search for Samsung Band Selection

  3. Download and install the APK

⚠️ Play Store doesn’t offer this app anymore, so use trusted APK repositories only.

✅ Step 3: Open the App and Access Hidden Menu

  1. Launch Samsung Band Selection

  2. Tap on Launch Band Selection

  3. You’ll be redirected to a secret Samsung hidden network settings menu

This uses Samsung’s internal ServiceMode to access band locking features.

✅ Step 4: Manually Select Your Preferred Band(s)

  1. Look for the option like “Band Selection” or “Set Preferred Band”

  2. You can now:

    • Enable/disable individual LTE or NR (5G) bands

    • Set preferred RAT (Radio Access Technology) like LTE only, NR only, etc.

    • Force combinations like LTE Band 3 + Band 40 for high-speed internet

  3. Save the settings and exit the app

📌 Pro Tip: Try testing different bands one by one and run a speed test (e.g., using the Speedtest.net app) to see what works best in your area.

⚙️ Alternative Method Using Dialer Code

If your phone supports it, try this dialer code method:

  1. Open the Phone dialer

  2. Dial:

    bash
    *#0011#

  3. Tap Menu > Back > Menu > Key Input

  4. Enter 0000, wait 10 seconds

  5. Tap Menu > Key Input again

  6. Enter Band Selection

⚠️ This method is model and firmware-dependent, and may not work on all newer Samsung phones (especially from 2022–2023 onwards).

📉 Risks and Precautions

Unlocking network bands is safe if used properly, but:

  • ❌ Don’t disable all bands — this can result in no signal

  • ❌ Avoid forcing unsupported 5G bands on non-5G SIMs

  • ✅ Always note default settings before changing

  • ✅ Use Airplane Mode ON/OFF after applying changes to refresh signal

📶 Testing the Network Performance

Once you’ve selected specific bands:

Tools to Use:

  • Speedtest by Ookla – For measuring download/upload

  • Network Cell Info Lite – For signal quality

  • Ping tools – For latency

Test with multiple bands at different locations and times to find best performance combinations.

📱 Supported Samsung Devices

This method has been tested and works on many Galaxy phones, including:

  • Galaxy S Series (S10 to S23)

  • Galaxy A Series (A52, A72, A73, etc.)

  • Galaxy M Series (M31, M33, M53)

  • Galaxy Note Series (Note 10/20)

  • Galaxy Z Series (Z Flip, Z Fold)

⚠️ Carrier-locked phones may have more restricted settings. Try using dual-SIM unlocked variants for best results.

🌐 Use Case Examples

Here are some real-life cases where unlocking bands helped users:

🔹 Case 1: Slow 4G, Fast Band 40
A user in India found slow speeds on automatic selection, but Band 40 (2300 MHz) gave 4x faster speed when locked manually.

🔹 Case 2: Weak Signal Indoors
Switching to Band 3 (1800 MHz) helped improve indoor coverage compared to Band 1.

🔹 Case 3: Forcing 5G on n78
In areas with patchy 5G, users forced n78 band only to enjoy consistent 5G speeds.

🧩 Frequently Asked Questions (FAQ)

🔄 Q1. Will this method work after software updates?

A: Sometimes Samsung updates remove access to these menus. If so, wait for updated versions of Samsung Band Selection or try the dialer code again.
