My father using this phone from last month.Biggest drawback of this phone is absence of HOTSPOT. With hotspot, Internet could have been of great use as everyone will have smart phones as standby. Otherwise, on such keypad it’s tiresome to use Internet features, so not a good choice. Company already announced that WhatsApp is not available. What now then. Jio phone is for only free calls abd work as only stand by device.1500rs deposit amount is refundable but after three years if it meet all the condition and aftrs returning the phone and this is not going to be happens.manufacturers look for their profit first then customers.
