Nokia N93 Specs

pls anybody list out all the mobile fone services in india and tell me if they r CDMA or GSM?
nokia 6275i specs says it's operating frequency is CDMA x1,800/1900MHz,so can it be used with any of the services in India.
pls do explain me about Reliance services in India and why don't they
have sim cards in them,is that a cdma service.Why india lacks few models of the Nseries like N93,N92?.will all mid end models work in almost all countries?
Reliance
TATAIndicom
MTNL
The above mentioned services are few CDMA services in India
GSM services are
Airtel
Hutch
AirCel
BSNL..
I have no Idea about Escotel..
Reliance is CDMA.. you can carry your Reliance fone to any part of India.. with National roaming.. all you have to do is .. you got to enter their service area code.. thats all.. that will allow you to the other reliance networks.. Reliance works in Chip.. like as we use SIM cards.. bcoz its for security purpose.. they secure their assets given to the customers.. you cannot use SIM in that mobile fone.. there are many factors.. they give netwap.. GPRS too..
