iPhone 6s plus lost imei after restart

So at night I turned of my phone and went to sleep. When I woke up and turned it on there was a no service message, I thought maybe there was a network issue but later on I thought maybe it was something else. Update the phone to the latest ios but still the error was there.. Then on checking *#06# there was no imei.. I read it was a hardware baseband ic issue.. Does anyone have a picture of how it looks like so I know if to order another one or toss the phone
