Have you ever experienced dropped calls or slow data speeds on your iPhone and wondered about your signal strength? Checking the signal strength on your iPhone is a quick and easy process that can help you troubleshoot connectivity issues. Let’s dive into how to do it!
Step by Step Tutorial: Check Signal Strength on iPhone
Before we get into the steps, it’s important to understand that signal strength is measured in decibels relative to milliwatts (dBm). A stronger signal is indicated by a higher dBm number, which can range from -50 dBm (excellent signal) to -120 dBm (very poor signal).
Step 1: Access the Phone App
Open the Phone app on your iPhone, the same one you use to make calls.
When you open the Phone app, you’ll typically see the keypad. This is where you’ll enter a special code to access the Field Test Mode, which displays your signal strength in dBm.
Step 2: Enter Field Test Mode
Dial 3001#12345# on the keypad and press the call button.
This code triggers the Field Test Mode, which is a hidden feature on your iPhone that provides technical details about your cellular connection, including signal strength.
Step 3: Check Your Signal Strength
Look for the numerical reading near the top of the screen, which represents your signal strength in dBm.
The number you see is a more precise measurement of your signal strength than the traditional signal bars. A number closer to zero indicates a stronger signal.
Once you’ve checked your signal strength, you can exit the Field Test Mode by pressing the home button or swiping up on newer iPhone models without a home button.
Tips for Improving Signal Strength on iPhone
- Keep your iPhone’s software up to date, as updates can include improvements to connectivity.
- Avoid physical obstructions, such as thick walls or metal, which can weaken the signal.
- Remove your iPhone case if it’s particularly bulky, as it might interfere with the signal.
- Switch on Airplane Mode for a few seconds, then turn it off to refresh your network connection.
- If you’re in an area with poor coverage, consider using Wi-Fi Calling to place calls over a Wi-Fi network instead.
