Summary: The reason I gave the HTC HD7 phone only 4 stars and not 5, was that I lost all but three of my SIM card contacts when I inserted the US card. I was prompted with the question: "Import SIM card contacts?" and I answered yes, and then only three were there.
Summary: Overall the phone is great. The only issue I have with it is that it has a tendency of freezing up when I am playing my music and the only way to fix the freeze is to pull the battery out of the phone. It does this about once a day.
This the the 2nd HTC I've owned in a 3 years spam...

Summary: Bought in USA and using it in Canada, just bought a SIM card and bingo! I works flawlessly and as expected. My first HTC lasted nearly 3 years without any problem so I decided to stick with the same brand.
