Just got an iphone 11 on tmobile network and i cant update or backup data over cellular network . I dont have access to wifi network or a computer .
Why do i have to connect to a wifi network to update ios instead of using my data plan to update ? My plan Includes hotspot data and ph can be used as a wifi hotspot so why wouldnt that be the same as connecting Or updating over my own network instead of another wifi network ?
iPhone 11, iOS 13
