I have been using jio since then since this has come and it’s very good
network service are too awesome, even after my daily 1 gb data exhausted in 128 kbps speed runs smoothly
I can’t say anything about this because I never get any chance to use there customer service, I never had to, may be they are too good in their network services so I never had to call them
their charges for data package are also very good
they offers you 1gb data on daily basis for 3 months, unlimited calls, 100 sms per day for 3 months
after you exhaust 1gb data you still use their net service in terms of 128 kbps speed
even on every recharge they give you voucher of 10 gb 4g data which you can redeem any time under 3 months
