After coming to India, I unlocked my phone through AT&T and bought a new sim card (Vodafone) and just recently initiated the 3g plan. However, upon starting it, it was apparent that the 3g would not work here, for i was constantly running on Edge. I was told that the band in America is lower than that of Indian company; I was told America runs off 1900mhz and India runs off at around 2100mhz. My Phone was of AT&T so im thinking it might only be going at 1900mhz, but I'm a bit confused because i unlocked it, unless that doesn't do anything to the band. So, anyway I was wondering if there was a solution to my problem? I've bought 3g network and it only runs off edge(2g). I read around about radio and something about rooting it, but I didn't want to try anything until i was almost sure it wasn't something that wasn't going to help me.
Also, even though i am no longer with AT&T, when i try to use my 2g for hotspot, it keeps telling me to enable tethering by calling 611..but that's not a valid number here in india haha.
So, thanks for reading and all help is appreciated.
