How to Fix 5G Not Working on iPhone

We have been in the era of 5G for several years, with more tech giants incorporating 5G connectivity into their smartphones. Apple first announced its iPhones built to work with 5G back in 2020, which received a warm welcome from the public. Since then, this wireless network technology has been an essential part of its iPhone lineup, with the latest iPhone 14 series boasting one of the fastest 5G in the smartphone world. 

However, there are times when 5G stops working on your iPhone. Many iPhone users have reported problems with the 5G network, ranging from poor signal to SIM incompatibility. No worries, we will show you how to fix 5G not working on iPhone.

How to Fix 5G Not Working on iPhone

Method 1: Check Your Carrier

5G is getting popular worldwide, but not all carriers support 5G, so it’s best to contact your carrier to learn if they support this wireless connectivity. Most big carriers like T-Mobile, Verizon, O2, or AT&T support 5G. If the carrier is not the issue, then it may be with your current location. Here is the list of all wireless carriers that support 5G across the globe. 

Method 2: Check Your SIM Card

Make sure your SIM is 5G enabled. If you bought your iPhone from your carrier or Apple, your SIM card should support 5G. However, there is a good chance that your old SIM card is not optimized for 5G. In this case, you can contact your carrier and check if your SIM card supports 5G. 

Method 3: Make sure 5G is working properly

If the problem persists, the following solution is to ensure that 5G is working on your iPhone. A 5G icon should show up in your status bar. If not, double-check if it’s working correctly. Here is how to do it.

  1. Launch Settings on your iPhone.
  2. Select Cellular > Cellular Data Option
  3. Check if the 5G Auto shows up on the screen.

Method 4: Toggle Airplane mode on/off

If the problem remains, try turning off Airplane mode and then turn it back on. To do it, tap Settings > Airplane mode and turn it on. Wait for 30 seconds and turn it back off. 

Method 5: Disable a Dual-Sim Line 

One of the most straightforward fixes for cellular connectivity issues is to disable a dual Sim line. In fact, if your iPhone now runs on iOS 14.4 or earlier, you are limited to 4G when using Dual SIM. To turn it off, go to Settings > Cellular > Turn off the switch for your line > OK

Method 6: Turn off Low Power Mode

Low power mode has been part of iOS for years, allowing users to extend their iPhone battery. Once enabled, it reduces the amount of power that your iPhone and iPad use when the battery gets low. It also turns off all wireless networks, including 5G. To turn off Low Power Mode, go to Settings > Battery and turn off the switch. 

Method 7: Reset Network Settings

Reset network Settings

If you still cannot connect to 5G, the last resort is to reset your network settings. Doing so will erase all your current networks and settings, including Wi-Fi networks, cellular settings, Wi-Fi passwords, and VPN settings. To do it, open Settings > General > Transfer or Reset iPhone > Reset > Reset Network Settings
