Can I use Dual Mode GSM/WCDMA?

[Kavin]

I got a JASJAR. I'm useing a GSM SIM-Card. Now, I want to add a new CDMA account to use 3G-service. Is it possible?
And How to do it?

I dont think its possible... Since JasJar doesnt support dual sim u can use both the sim at the same time... If u want to use both the services like GSM or WCDMA then u will have to have those services in the same SIM itself.

WCDMA and UMTS are the same thing. WCDMA is the radio-technology used, UMTS is more the general name for the whole system.

no

CDMA orginates from the old analog system which were in europe called NMT
