Yesterday i got an unlocked Softbank 911T, I was wondering if i need a 3G simcard (i have a 2G optus prepaid sim) to use some of the features? like it keeps asking me if i want to "start retrieval network info" and when i press yes, it says "retrieval network info failed". i dont understand and the instruction manual doesnt help at all.
Will it work if i change to 3 prepaid? i still want to stay with prepaid but how much will it cost to get a new sim card from 3, just the sim card?
Or i could change to Optus 3G, would that work?
and what is a USIM? do i need one of those for this mobile because i think i do
Also can i use internet on the phone because its a japanese phone so i'm not sure, and if yes then how?
I'm REALLY confused, please help!!
