I have the same issue, started with intermittent no signal. Had to restore it 3 times with itunes before signal gets back. Was good for about 20minutes and now no connection at all. I thing i’ll try installing ios 14 beta2 maybe i’ll help

Apple, tonight, I had a problem with my car. Right after my night shift. At 2am. In the middle of ***** no where!! The transmission gave up! I dont know if you know but here in canada its *** cold at night right now... I tried to call the roadside assistance but guess what? My apple watch didnt had enough power to make the *** call. Now what?! I’m stuck on the side of the *** road without any warm clothes and I HAD TO MAKE A HUGE 50 MINUTES WALK TO CALL MY WIFE AND SEE ANY SIGN OF LIFE. Just imagine if didn’t had this small sweater. I would have frozen outside. Without heat and anyway to join someone I could have die if the temperature would have been colder. Thank you apple for being what you are. Tomorrow i’ll sell both my apple watch and my iPhone. Never coming back with you guys. This was too much for me. I just hope someone wont have a big accident and die because of this ***** bug. Make an update as soon as possible so people can get home alive. Sorry my language but this bug deserves it

They just want to get rid of the iphone 7. They build so good phone that the only way to sell the new ones is to kill some of the oldest one. I pretty sure they wont admit this issue. And sadly everyone with an iphone 7 with this trouble gonna have to buy a new one. Think about it. How would you make money if everyone stop buying phone because they are too good? They say iphone 12 is 4x better than every other phone on the market, yeahh... pretty sure it will be as good as new in 5 years but it will be outdated so they’re gonna find a way to kill them. I say a couple threads about this bug and every time someone referring to the recall for the baseband. Mine isn’t covered cause its a A1778. I hope I’m not right about this. Waiting 14.0.2 with a lot of hope. Good job apple
