I'm with Wind Mobile and my dad is with Fido. My dad is going to buy me the HTC One S because he's on a 3-Year plan with them. I want to know if that's going to work with the Wind Mobile Network if I get the phone unlocked. How do I know if an unlocked phone will work with Wind Mobile? I don't know if this will help, but here's the frequencies for the HTC One S(Fido):

GSM : 850/900/1800/1900*
HSPA : 850/900/2100

And here are the frequencies for the Galaxy Nexus on Wind mobile (Just to Compare):

GSM/GPRS/EDGE : 850, 900, 1800, 1900 MHz HSPA AWS 1700 MHz, 900 MHz and 2100 MHz

How do I know for sure if this phone will work on Wind Mobile?
