  1. I am in a longer pursuit of ensuring SAMSUNG Ace Duos SCH-i589 will work with my BSNL EVDO service of 3.1 Mbps. I want to use my Reliance service for voice and BSNL for data on the SAME phone. During my first attempt, Samsung sales guys told that the RUIM card must be OMH. When I contacted BSNL, they said there is a patch to make the legacy RUIM OMH compatible. BSNL Bangalore guys patched the RUIM and given me back. Again I have taken the RUIM the Samsung sales. But they were quite unaware of the process of enabling the EVDO service on this mobile. I have written the matter to Samsung but in vain. Later, I have visited few Samsung Service centres following this. They have asked me to visit the Samsung R&D guys in Bangalore. But the insensitive staff did not direct me to any of the right guys. Later I caught hold of some marketing guys of Samsung. The first response of them was quite surprising! They are not even aware of a CDMA service by BSNL. They were even daring to “educate” me stating there is no CDMA service provided by BSNL. I could make them listen to my queries after stating that I am already a BSNL subscriber! During this conversation, Samsung says they are not responsible to compatibility of their services with “non-standard” service providers like BSNL; it seems they consider only providers like Reliance, Tata, MTS etc. As of now, they have agreed to check again about these compatibility issues and come back. From their response I am not sure, how much it would be hopeful. Current technical status is these: · The RUIM is recognized as an EVDO RUIM in the mobile · I am able to receive calls using the RUIM · But I am not able to configure this for data. · BSNL staff in Bangalore confirms that some subscribers are already able to use this phone for EVDO data, (after the patch); but they are unable to configure it themselves and asks me to go to Samsung! CAN YOU OR SOMEONE ELSE CAN GUIDE ME, HOW CAN I MAKE USE OF MY BSNL EVDO RUIM ON THIS MOBILE FOR DATA?
