i have a samsung galaxy s3 unlocked in the UK. i will be in America from july to November so i want to be able to use my s3 over there. the carrier which is good for my phone is Spot Mobile. the trouble i have is that the sim card states that the phone needs to be on 1700mhz for hsdpa+ and 4g but according to the specs of the phones it doesnt support this. surely this cant be correct. i used a 4-5 year old arc s and it worked in america now a modern phone from the past 2 years wont get 3/4g network. is this correct or am i overlooking something. i would like some feedback from this. thanks.
