Update your iPhone 13!
If you have an iPhone 13, you need to update your software to the latest version for the best possible 5G network experience. If you’re running an older software version, you may connect to LTE when you should get 5G. Check out What is 5G? to learn more about 5G and get steps to update!
If a message asks to temporarily remove apps because the software needs more space for the update, select Continue to allow apps to be removed. After installation is complete, those apps are automatically reinstalled. If you choose Cancel instead, you can delete content manually from your device to add more space. Visit Update your iPhone or iPad - Apple Support for additional support.
