Does anyone know which one is faster when it comes to data? I currently have h2o data works and mms work but I have bad reception at home. people cant really hear me when im inside my house. How can I tell if my internet is 4g? Another question if I was to unlock my lumia would I be able to use on T-Mobiles 4g? T-Mobile data on my last phone the htc hd7 was really good everywhere and no one can beat 5gigs a month.
