I purchased this product in April 2010 after seeing lot of advertisements and recommendations. Alas! using it turned out to be a night marish experience. The phone if not used for couple of hours, automatically goes to emergency mode, no one can reach you or you can make call. You have to switch off the phone and switch on to activate the sim card. Sound clarity is awful. So much disturbance while talking. Sometimes the phone automatically tries some number. It is difficult to use while going for brisk walk or morning exercise, as the song keeps jumping from the first few lines to last line because of slightest jerk. Service is worst. If you get the toll free number, it keeps disconnecting quite frequently during the conversation and everytime you have to repeat the problem to a news call centre executive. They promise to resolve within 48 hours but will not respond in 72 hrs even. So my request you to all, please keep away from this product.
