It definitely works, I have seen someone using it but I have no idea how.
It will work but only after registering it's MEID with reliance (which end user can't do directly), unlocking MSL, NAM & Data provisioning the handset with Reliance network.
It won't work out of the box directly when imported from
Ebay US.
@Mukul
Go for the handsets suggested from the RIMweb forum earlier in the topic. You'll get the latest and best imported CDMA handsets at prices unthinkable in GSM. I am an active member there.
Do not bother for CDMA SIM enabled handset only as you won't get any because all US CDMA networks run with programmed handsets for all models.
Even if your dad currently has a Reliance CDMA SIM, transferring that number to the imported handset is not an issue and can be done easily. The seller will explain the process to you.
There is one
Motorola Droid Pro Global listed today on the forum at attractive price of Rs 11,000 >>
For Sale: Brand New Droid Pro GSM Unlocked + CDMA - Reliance Mobile (CDMA & GSM) - Discussion Forums
This is a global phone, which means you can use it in Reliance CDMA (programming ) and it can also be used for any GSM network after inserting SIM. This is either network but one at a time.
Another model which i suggest if you like QWERT Slider Keyboard is Sprint
Samsung Epic 4G. This also can be had within 15K.
