4G not working. Only 5G is working on my iPhone
I recently purchased an iPhone 14 Promax. It has been working absolutely fine until the iOS 17.2.1 update. Suddenly I can’t get internet on 4G. When I drive to a 5G area it works. The problem is 90% of locations are still on 4G so I can’t use my phone in a 4G area. It works perfectly fine in 5G areas. This is very frustrating. I called the network provided and they spent 2hours on the phone testing, refreshing data from their end, asking me to remove sim etc. At the end, they said it’s an Apple issue. My WiFi works fine. My 5G works fine. The only problem is I get disconnected when I am in a 4G network area because my phone internet dies. Any help or advise for this totally frustrating issue pls?
