Try an Orange Sim in it, if that doesn't work the phone is faulty on 1800MHz

The last monobanders were Nokia 51xx of 1997

Is it possible that the phone's imei is in the t-mobile blacklist? A new
phone imei shouldn't be blacklisted, but that doesn't mean it's impossible.

As other posters have suggested, try an orange sim - if orange and
t-mobile both fail I'd guess it was an 1800 fault.

You say it's dual band .... could it be dual band 900 / 1900 (usa
standard) and not 900 / 1800?
