Getting a weak signal on iPhone is one of the most common problems that iOS users may experience. It can be caused by a number of issues with the device, that we will address below, along with some easy fixes to improve weak iPhone signal. Keep reading.

Why Does My iPhone Have a Weak Signal?

A poor iPhone signal can be caused by a number of factors. The following are some of the most common reasons why your iPhone may have a weak signal;

  • Problematic network coverage by your cellular provider.
  • Outdated apps or an outdated iOS system.
  • You are in an area with terrain or buildings that may be blocking the signal.
  • When too many people are trying to access the same network at the same time.
  • Your iPhone cover may be blocking the device’s antennae from receiving the signal.

The following are some of the best solutions that you can try to improve your weak iPhone signal;

1. Make Sure the Cellular Data is On

The first thing you should do when your iPhone has a weak signal is to make sure that the Cellular data on your iPhone is turned on. Just go to Settings > Cellular Data and ensure that the toggle is turned to "ON."

If you are travelling or in an area not covered by your local network, switch to Data Roaming. Go to Settings > Cellular > Data Roaming to do that.

2. Restart Your iPhone

Your iPhone may also fail to connect to the network because of minor glitches that may be affecting its primary functions. Restarting the device is one of the best ways to get rid of these glitches and get your iPhone working normally again. Follow these steps to restart your iPhone;

  1. Press and hold the Power/Side button and one of the volume buttons at the same time for a few seconds.
  2. When you see the “Slide to power off” prompt appear on the screen, release both buttons.
  3. Drag the slider to turn off the device. Wait at least 30 seconds and then press and hold the Power/Side button again until you see the Apple logo.

3. Remove Your iPhone's Case

Most iPhone cases will not interfere with the device’s antennae at all, but some can cause a loss in signal strength, particularly in older iPhone models.

You can determine if the iPhone case is the problem by simply removing it from the device. If the signal strength improves significantly or you have a better quality phone call experience, then the case was the problem and you might need to get a new one.

4. Find A Better Location

Cellular networks can be affected by a lot of things beyond your control, including buildings, terrain such as mountains and sometimes even large objects.

Therefore, sometimes you can improve your signal very easily bymoving to a better location. If you are in your house, try moving around or going outside. You may find that some sections of your home have better reception than others.

5. Turn Off 5G

If your iPhone supports 5G and you have a 5G data plan, it will automaitcally switch to 4G whenever there is a poor 5G reception or the device is out of range.

But this may not always happen and you end up stuck on a 5G network that is weakened by too many people trying to connect to it simultaneously.

You can fix this problem by turning off 5G manually. You can disable 5G on your iPhone when the 5G service doesn't work in your area.

6. Toggle Airplane Mode On and Off

If you are still getting a weak signal on your iPhone after turning off 5G, then you can try to turn on the Airplane mode, wait for a few seconds and then turn it off again. Airplane mode will turn off all radio connections on your device and help to solve the iPhone weak signal issue.

To do this, swipe out the Control Center from the bottom of the screen, find the icon of the Airplane mode, click it to enable this feature for a few seconds and then click again to disable it.
