Answer the question about text:

Turns out that even if we unlocked the phone , we still would n't be able to use it in NZ becauase it 's the wrong frequency . Again we had been told we could so we were not impressed . After this , Mike 's mother took us ddown to this really neat restuarant for breakfast - $ 7.95 eat all you want . They had amazing food . I honed in on the french toast and pancakes ! !

What may happen after unlocking our cell in NZ ?
The cell would have no coverage available .
