How to Check Your Signal Strength on iPhone

If you’ve ever been in a conversation on your iPhone and the call dropped, it might be because of poor signal strength. Checking your signal strength can give you an idea of why this might be happening and what you can do to fix it. It’s important to note, though, that signal strength might not always be the reason for dropped calls as they can also be caused by other factors such as network congestion. In this article, we’ll go over several methods to check your signal strength on your iPhone and what to do if you can’t get a good signal.

Why You Need to Check Your Signal Strength on iPhone

Your iPhone’s signal strength indicates the quality and strength of your cellular or Wi-Fi connection. Having a good signal strength is important because it affects the quality of your calls, the speed of your internet connection, and can even affect battery life. By monitoring your signal strength, you can easily identify why you might be experiencing issues such as dropped calls, slow internet speeds, or difficulty connecting to Wi-Fi.

Method 1: Using the iPhone’s Field Test Mode

The iPhone has a hidden field test mode that allows you to see more specific details about your signal strength. Here’s how to access it:

  1. Open the Phone app and dial *3001#12345#*
  2. Press the call button, and you’ll immediately switch to field test mode.
  3. Look for the signal strength indicator on the top left corner of the screen. You’ll notice that it’s a number instead of the traditional signal bars.

Steps:

  1. On the top left corner of the screen, you’ll see a number ranging from -40 to -130. The closer the number is to -40, the better your signal strength is. If it’s closer to -130, that means your signal strength is weak.
  2. Move around your location and see how the number changes. If you notice that the number fluctuates in certain areas, it could indicate interference or network congestion in that specific area.
  3. If you’re looking for more information, tap on the number to switch from numerical values to signal bars.
  4. You can also check out other fields such as serving cell measurements, neighbor cell measurements, and LTE information by swiping right on the top bar.

Pros:

  • Allows you to get more detailed information about your signal strength including specific measurements.
  • Can be used on any iPhone model.

Cons:

  • Might be confusing for some users to access and use.
  • Field test mode doesn’t save changes you’ve made and only shows real-time results.

Method 2: Checking Your Signal Strength in Settings

You can also check your signal strength using your iPhone’s settings. This method is straightforward and can also show you other Wi-Fi or cellular networks in the area. Here’s how to do it:

  1. Open the Settings app on your iPhone.
  2. Tap on "Cellular" or "Wi-Fi" depending on what network you want to check.
  3. On the next screen, you’ll see a list of available networks. Below each network’s name, you’ll see a series of bars that indicate signal strength. The more bars a network has, the stronger your signal.

Pros:

  • Easy to use and can quickly show you available networks and their signal strength.
  • Any iPhone user can access this feature as it’s located in the phone’s settings.

Cons:

  • Doesn’t provide more specific details about signal strength or network information.
  • May not show all nearby networks.

Method 3: Using Third-Party Apps

There are various third-party apps available in the App Store that can help you check your signal strength on your iPhone. Some of these apps provide real-time signal strength data and display it in an easy-to-understand format. Here’s how to use them:

  1. Open the App Store on your iPhone and search for "signal strength."
  2. Browse through the available apps and read reviews and ratings before deciding which app to download.
  3. Download and install the app you’ve chosen.
  4. Open the app and allow it to access your location and network information.
  5. The app should now display your signal strength in real-time.

Pros:

  • Can provide more specific information about signal strength and network data.
  • Some apps have additional features such as Wi-Fi speed tests or network congestion maps.

Cons:

  • Some apps can be costly or display ads.
  • May not be accurate and can sometimes use a lot of battery life.

Method 4: Using a Network Provider’s App

Your network provider might have an app that allows you to check your signal strength in real-time. Some of these apps have additional features such as data usage tracking or Wi-Fi calling. Here’s how to use some of the most popular network provider apps:

Verizon Smart Family:

  1. Download and install the Verizon Smart Family app from the App Store.
  2. Open the app and sign in using your Verizon account information.
  3. On the main screen, you’ll see a signal strength indicator.

Pros:

  • Can provide network-specific information and features.
  • Some apps have additional features such as Wi-Fi calling or data tracking.

Cons:

  • Not all network providers have an app available.
  • Some apps might only be available for certain plans or have limited functionality.

What to Do If You Can’t Get a Good Signal

If you’re having trouble getting a good signal on your iPhone, here are some things you can try:

  • Move to a different location: Sometimes, you might just be in an area with poor signal strength. Try moving to a different location in the same building or outside. Elevating to a higher floor might also help.
  • Toggle airplane mode: Try turning on airplane mode for a few seconds and then turning it off. This can sometimes reset your network connection and improve signal strength.
  • Reset network settings: If you’re still having trouble, try resetting your network settings. This will erase your Wi-Fi passwords, Bluetooth connections, and cellular settings, so make sure you have this information saved somewhere before doing this. To do this, go to Settings > General > Reset > Reset Network Settings.

Bonus Tips

  1. Put your phone in a case that doesn’t interfere with the signal. Some cases, particularly those that have metal in them, can interfere with your signal.
  2. Update your iPhone’s software. Network connectivity issues can sometimes be resolved with an update.
  3. Use Wi-Fi calling when possible. Wi-Fi calling uses your Wi-Fi connection instead of cellular data and can help when you’re in areas with poor cellular signal.

FAQS

Q1: Can signal boosters improve my signal strength?

A: Yes, signal boosters can improve your signal strength. They work by amplifying weak signal and increasing coverage area, but they’re not a guarantee and may not work in all situations.

Q2: Will a lower signal strength always result in a dropped call?

A: Not always. Dropped calls can sometimes be caused by network congestion or other factors such as a weak battery or hardware issues. It’s always best to check your signal strength and other factors before assuming it’s the cause of a dropped call.

Q3: Can I use the field test mode on my iPhone for other networks?

A: Yes, as long as you have a compatible SIM card. The field test mode should work with any network, but it might not provide all the same information as it would with your primary network provider.

Q4: Why does my signal strength fluctuate?

A: Your signal strength can fluctuate due to a variety of factors such as network congestion or interference from other electronic devices that emit electromagnetic radiation. Other factors such as weather conditions or physical obstructions can also affect your signal strength.

Q5: Is it normal to have weaker signal strength indoors?

A: Yes, it’s normal for your signal strength to be weaker indoors due to physical obstructions such as walls or interference from other electronic devices. Using Wi-Fi calling or placing your phone near a window can help improve signal strength.

Final Thoughts
