It is an ultimate phone to endup your search for a long battery backup time giving , a hassle free and hangup free operating phone. It was always a problem for me to be in touch with my family and friends whenever I went for a official tour because no yesteryears phone would give you more than 6-8 hours of battery backup time but this device gives 12 hours of battery backup quite easily. So friends grab this wonderful 4g phone coming in a reasonable price.
