I have purchased Reliance data card and used for sometime.Disconnected on request due to coverage and low speed problems in May 2007.Now I wanted to take a new Prepaid Internet connection from Reliance Infocom in this Data card.I have gone to Reliance Webworld to load the prepaid internet connection but couldn't be succeeded due to the reason that data card is not blank even after 5 months passed.I contacted customer care so many times to blank my device but not done so far. My device model no is HUAWEI EC325.

If anybody has any Idea how to blank this device for reuse let me know!
