5G Is Not Working on iPhone 12? Here is How to Fix

Currently, the iPhone 12 is one of the first Apple smartphones that support 5G connectivity. When it works, 5G does grant a much faster and more stable internet connection. Unfortunately, a lot of users reported that 5G was not working from time to time on their new iPhone 12, iPhone 12 Mini, iPhone 12 Pro, and iPhone 12 Pro Max. Some phones even display No Service in the status bar. So if you are among the users experiencing this issue, here are some tips to fix the 5G not working issue on iPhone 12.

Check Your Carrier Plan

Before trying to tweak any settings, you should double-check with your phone carrier to see if your plan includes 5G connectivity or not. Different carriers may imply different policies for 5G connectivity. In particular, Verizon requires some users to change their plan which, costs a little bit more in order to get 5G. Meanwhile, AT&T also alerts users to upgrade their plans for 5G when logging into their accounts.

If it’s possible, you should grab another iPhone or smartphone that uses the same carrier plan to see if the root of your issue is coming from bad signal coverage.

Check Your Sim Card

If you bought your iPhone 12 from your carrier with a 5G-included plan, you will have no trouble with your SIM card. However, if you bought a SIM-free phone and use the SIM card from your old iPhone, it may not be compatible with 5G. In this case, you may have to buy a new one or contact your carrier to ask for upgrading your existing SIM card to support 5G.
