Cellular Network Coverage: The first reason your iPhone may not be displaying 4G could be due to network coverage. Sometimes, the coverage in your area may not be strong enough or there could be technical issues. You can check network coverage by going to Settings > Cellular > Cellular Data Options > Enable LTE. If it's set to "Data Only" or "Voice & Data," try changing it to "Off" and see if it helps. 2. Network Settings Issues: Sometimes, your iPhone's network settings may be configured incorrectly or may have been reset, causing your phone to not display 4G. You can reset your network settings by going to Settings > General > Reset > Reset Network Settings. This will delete all saved Wi-Fi passwords and Bluetooth connections, so make sure to have them handy before resetting your network settings. 3. SIM Card Issues: Another reason your iPhone may not be displaying 4G could be due to a faulty or damaged SIM card. Try removing the SIM card and reinserting it, making sure that it's properly seated in the tray. You can also try cleaning the SIM card and tray with a dry cloth. 4. Software Issues: Sometimes, software issues can cause your iPhone to not display 4G network. Updating your iPhone to the latest software version can help fix this issue. Go to Settings > General > Software Update and check for the latest update. III. Tips to Ensure Your iPhone Displays 4G 1.

Use LTE or 4G When Streaming: If you're streaming videos or music, make sure to switch to LTE or 4G for faster download speeds. 5. Monitor Data Usage: Keep track of your data usage to avoid exceeding your monthly limit. You can check data usage by going to Settings > Cellular.
