Check the service status and see if there are issues in your local area https://status.o2.co.uk

Also check these guides Guide: How can I sort out my network issues? 

Also Companies all use different masts (in some areas they share masts), also it depends on how far you are from the o2 mast, and how that signal penetrates walls due to power loss and radio signal degradation.

Check these guides Guide: How can I sort out my network issues? and Guide: Do you have poor coverage / signal Indoors? This may help Explain / resolve it 

If they don't help then maybe new sims may be the answer?
