Hello

I have a T-Mobile contract on my n900. It works fine in Holland, Belgium and Germany. However, in the UK I cannot connect to any provider at all (both 2g/3g). I get 'SIM card rejection' or 'call cannot be established'. The same SIM card works in N97 in the UK so it is not a provider issue.
I found threads about similar problems with 3 UK provider and old firmware, but mine is new PR1.2.
Any suggestions? Thanks
