Reliance jio speed is really poor . I complaint to customercare but they not response well. They tell me to 48 hours to solve my problem but the problem remains the same. Some setting change in apn which , I folled by youtube which guarantee to increase internet speed but all are not working as well. Taking about call facililies it seems like very good but the call droped and you need to call 7 to 10 times to connect a call and some times even more than this limit. By the time passes I expect that the facilities of call and internet may improve but now it is not like true 4g or any thing like that.TRAI has said that this is the slowest 4g connectivety.
