In what areas of the world is 900mhz used for cell phones?

Question

Because i'm getting a tri-band phone and the tri-band doesn't have 900mhz while the quadband does. Like what places in the world only have 900mhz coverage? Thanks.

Answer 1

900 I thought were one frequency range for home cordless phones.I thought all cell phones are mainly 800 mhz. Some all over is expanding to the first part of 900mhz.band. Call a cell phone company found in yellow pages and ask them
