Same company but TMobile doesn't offer the iPhone in the USA so u will have to unlock it first in order to use the TMobile sim card.

You need to unlock your mobile inorder to use it with T-Mobile,USA.Eventhough T-mobile is the same company it operates different in each country.You can avail the unlocking service if you contact the Europe T-Mobile network or you can avail the remote unlocking service from online vendor like and follow their free unlocking instructions to remove the network lock.
