Hi all, I recently bought a Blackberry 9000 (3G only -- it dates from 2008), and the Melbourne-based vendor assured me it had been tested thoroughly and definitely worked on the Optus network. But when it arrived out here (near Ensay in Vic - postcode 3895) it displayed "no service" and could only find the Telstra network. (Our other phones work fine on Optus.) According to US data, the 9000 only has 3G at 2100 and 850MHz, and does not have the 900MHz band. Could it be that it worked fine for the vendor in Melbourne on the 2100 band, and won't work out here because the Ensay tower (possibly) only provides 3G at 900MHz, and not 2100? (The fact that the phone can detect the Telstra network must be due to it being equipped for Telstra's 850MHz band.) What I really need to know is, what are the current 3G frequencies for the Ensay Optus mobile tower ?? Thanks for taking the time to wade through all this!

You are correct, the tower in Ensay is not putting out 3G on the 2100 Mhz band. This is not uncommon with more rural areas as it's a short range band and isn't likely to be available to many people at all if it was there.
