wats that?
some phone has tri band and some phone has quad band wats the diiference?
Triband means ur fone is able to access GSM 900/1800/1900 MHz networks
Quadband means ur fone is able to access GSM 800/900/1800/1900 MHz networks
depends on the country and provider is providing which networks
so if you go overseas...you will still be able to use the phone based on the teleom operator in that country...
