Same location same skinny prepaid sim
Download around 120 to 140 max on both devices, upload in low 40s on iPhone 6 on iOS 12
Upload max is 13 on iPhone XR on latest iOS 13.2.2 And also on previous release which I think was 13.1.?
iPhone XR has been dfu’ed which is meant to reinstall the os
What’s the iPhone XR not using?
