Dont ever buy this instrument. I have been putting up with this piece of crap for the past one year just because i was bound by contract.Every 12 minutes into my call the signal gets lost with this phone. Imagine the situation when you are on an important call and the connection gets severed because of the faulty phone.When i call the customer support people to complain about the signal they remorselessly say its bacause of the phone. Then i wonder why the heck they are offering such a piece to customers. Are they trying to loose customers? The battery life isn't good either - just about 2 hours.
