My IPhone 5s has no service?

Ok so i tried to update my phone to ios 9 and the first process completed then it couldn't complete the second one cause i have no service -.- and now i can't connect to any apps and there's some stupid red dot above my phone app.-. And we turned my phone on and off and it didn't work, i set my phone to airplane mode and it didn't work either, the same thing happened to my friend at school too, and i don't know what else to do. Can someone please help me out!

I read about this, it was a bug in iOS 9

So connect it to computer and finish the update. It updates way faster connected to computer also.

Go to he apple store, they will fix it for free. If they can't make them give you a new one because its their problem and not yours.
