I am using since 15 September.When I am using jio sim intenet speed really good.In mornings I will get arround 10 mbps speed and night its increasing upto 18 mbps.But call drops occurred.Now a days speed are too slow like 3 mbps and calls are still droops.My question is that why jio offer free sim and internet and calls free for 3 month’s. If jio is not continue the speed while millions of people nion jio now a days.So I’m requested to to increase the number of signal strength to everywhere.
