No service to Iphone 5s after IOS update

Ive been in touch with Three, my provider who have guided me through every last step to try and resolve this. I have thus far reset wireless settings, checked my carrier settings, done a total restore. Nothing is working. I have been given such a load of excuses from Three, such as mast congestion, fixing a problem in my area etc. There are no problems as a check shows good strong signal in my area. I have a feeling that the lastest update isn't compatible with the phone. Whats going on? Please help as this has been going on for 3 weeks.

The phone will not update if an update is incompatible with a particular model of phone.

The iPhone 5s is shown on Apple's iOS11 compatibility list - so all 10.3 updates will certainly be compatible

Take it flight mode is turned off.

If so maybe turn it on for 5 minutes then turn it off again that should also reset your connection.

Worth a try I suppose.

Could you roll back the update? Ask them to get back it to the previous version.

How do I roll back an update? Any clue? I will try it but cant see an option to do this either on my phone or via iTunes

Try using someone elses sim card. If that works you know you sim card is faulty. I have had 3 days trying to sort my new sim card with the same problem. Tried my grandsons sim in it and it worked fine.

So basically they sent me a new sim card and never validated it when I phoned them. still waiting.

I have already tried her sim cards to no avail. I'm stumped!

sorry that should say I tried other sim cards, to no avail
