I have a UK Lumia 900 . Other than signing up for a 4G sim how can i tell if is 4g enabled and not just 4G ready?
I believe that only the AT&T version of the Lumia 900 for the US supports 4G(LTE). Your UK Lumia 900 is neither 4G ready nor 4G enabled..
Only the NAM (AT&T) Lumia 900 model has 4G support and that model does not work with the 4G bands used in the UK.
