Intermittent service/ no 4G after 14.4.1 update

Is anyone else having the issue of intermittent service/ no 4G after the latest update on their 6s? Any ideas on how to resolve apart from the usual reset settings, take out SIM etc? Thanks

iPhone 6s, iOS 14

Thanks for your reply! I’ve tried all of those options with apple support today and it’s still not working. It happened after the previous update too, I was sent a new SIM by my provider, had the phone looked at and it’s not a handset fault. I’m not sure if apple is not supporting 6s any more and just phasing them out or my phone doesn’t like updates!
