Guys I have an iPhone X since 6th November and I have problems with LTE/4G speeds...I updated to latest iOS version but no luck...
Any idea how I can fix this?
Spontaneous idea out of the blue: try to reset your network settings. Settings>general>reset>network settings BTW: my phone language is set to german so I translated the menu spontaneous (maybe they are called a bit different).
What do you mean by having problems with the speeds? Is it having trouble finding and keeping the cellular signal? Have you been able to test the phone in different locations, as well as using another phone or model to test on the same network?
