how to check signal strength of all available network operators

Knowing the signal strength of different network operators in your area is crucial for choosing the best mobile plan. A strong signal ensures reliable calls, fast data speeds, and fewer dropped connections. This article will guide you through various methods to check the signal strength of all available networks on your phone, regardless of your current provider. We'll cover Android, iOS, and some third-party apps that can provide detailed signal information.

Understanding Mobile Network Signal Strength

Before we dive into the methods, it's helpful to understand what signal strength actually means. Signal strength is measured in decibels-milliwatts (dBm). A higher (less negative) dBm value indicates a stronger signal. For example, -70 dBm is stronger than -90 dBm. However, the exact interpretation can vary depending on the network technology (4G, 5G, etc.). You don't need to memorize dBm values; just focus on comparing readings between different operators.

Methods to Check Network Signal Strength

There's no single, universal method built into all phones to check all available network operators simultaneously. However, we can combine several techniques to get a comprehensive picture.

Method 1: Using Your Phone's Built-in Settings (Android)

Most Android phones offer a way to see the signal strength of your current network. The exact steps may vary slightly depending on your phone's manufacturer and Android version, but generally, you can follow these steps:

Open Settings: Locate the settings app on your phone.
Find "About Phone" or "System": The exact name varies.
Look for "Network" or "Status": This section often contains network information.
Check for "Signal Strength," "Network Status," or similar: This will display your current network's signal strength, often as a numerical value (dBm) or a visual indicator (bars).

Limitations: This only shows your current network's signal strength. To check others, you'd need to switch networks (if possible) and repeat the process. This is inconvenient and may require a SIM card from each provider.

Method 2: Using Your Phone's Built-in Settings (iOS)

iOS doesn't directly show numerical signal strength values like Android. Instead, you see signal bars. While this isn't precise, it can still give you a relative comparison. You won't find a direct "signal strength" option in settings. The number of bars displayed is a general indication; more bars usually mean a better signal.

Limitations: Similar limitations as Android – it only shows your current network's signal strength. It also lacks the numerical precision of dBm readings.

Method 3: Using Third-Party Apps

Several apps on both the Google Play Store (Android) and the App Store (iOS) provide more detailed network information, including signal strength for multiple operators. These apps typically use your phone's location and scan for nearby cellular towers. Be aware of app permissions; some require location access.

OpenSignal: A popular app that provides detailed network coverage maps and signal strength data.
Network Signal Info: Often provides detailed technical information about your network connection.
CellMapper: Another popular option known for accurate signal strength measurement.

Note: The accuracy of these apps depends on many factors. Always compare the data from multiple sources.

Method 4: Field Test Mode (Advanced, Android-specific)

Some Android phones have a hidden "field test mode" that shows more detailed network information, including signal strength. Accessing this mode typically involves entering a specific code (e.g., ##4636##) through the phone's dialer. However, this code varies greatly depending on the phone's manufacturer and model. Once enabled, you can usually find signal strength data in the "Cellular Information" section.

Warning: Field test mode is intended for technical users. Incorrectly using it might not cause harm, but it's not a user-friendly method.

Choosing the Best Network

Once you've gathered signal strength information from various methods, you can compare the readings. Remember that a stronger signal is generally better for call quality and data speeds. However, signal strength is not the only factor; network congestion and overall network performance also play vital roles. Consider these points when selecting a network:

Signal Strength Consistency: Look for consistent strong signals throughout your daily locations.
Data Speeds: Run speed tests on each network to compare actual data throughput.
Network Coverage: Check coverage maps provided by the network operators to verify their claims.
Customer Service: Consider the reputation and quality of the network operator's customer service.

By combining the methods outlined above, you can gain a much clearer understanding of the signal strength provided by different mobile network operators in your area, empowering you to make a more informed decision about your mobile plan. Remember to always prioritize reliable sources and critically evaluate the data you gather.
