Actually I see this device at my friend’s home it is so light wight comfortable and easy to use. I like coler of this device. it would be best from purchasing new costly 4g mobile(smart phone) because I have bought it few weeks ago. it can catch good signal even in low signal areas. jio router is given free calling also by this device and it has good customer services. I can compare it form other devise it would be good eventuate from every perspective. I love it.
