Hi, Zakir,
Why u want to switch off your mobile when u are in office. If u switch off your mobile, your near and dear will not able to contact u in any emergency. The very purpose of the mobile will be defeated. Mobile is an instrument which keeps u connected with all your near and dear. It is better that instead of keeping the mobile switch off, u may keep it in silent and vibration mode. In this case, u may not miss the call.
