Jio — Not able to call

Address:	Thiruvananthapuram, Kerala
Website:	Jio

While calling it shuts off automatically without any information and thus no calling is possible.And also No one is able to contact us and is asked to contact customer care.It often ends call automatically. Range is low and hence it goes slow at times.sometimes the sim turn off automatically. And should power off and on to make it correct.often shows, "jio TV is unfortunately not working".speed for browsing is also slow.
