Same issue here: Iphone 6S Network: Movistar (Spain) Worked perfectly well on Ios 14.0 ... one night after restart, started looking for network signal and not found. The message displayed is that it needs an update. Tried update over Wifi and said 14.0.1 was available. I downloaded the package but.... "Update could not be verified because it was not connected to Internet" _(WTF... meanwhile whatsapp and imessages were entering the phone). I connected it to the desktop.... downloaded 14.0.1 through Itunes, installed it, no issue.... iphone reboots.... same error message. Mobile network (Error) - Your mobile needs an update. Now it displays "Your Iphone is up to date with Ios 14.0.1" Changed SIMs to see if there was a bit more luck ... same behaviour .... the iphone does not even asks to unlock the SIM after restart. Only asks for code and with no SIM unlock, stays looking for network signal. I think some developed f*up on the process calls to unlock SIM cards. Until the guys do not issue a new package 14.0.2 ... I guess we have just a very expensive brick on our desks that can not make calls.
