Since launching of jio sim peoples are very exited to use jio sims they buy 4G-LTE phones for firstly their is the main reason that all the people knows that jio is giving free data offers, free calls to any network free text message talk in the today’s generation people don’t live without mobile and internet and all of us know that without internet mobile is useless for teenagers they want internet as talking to the network coverage it has some problems which people are suffering but this is bcoz now the two of three people are using jio for free internet so the bandwidth should be affect as well as we talk customer service of jio is very good and cooperative they help to solve our problems very friendly some are complaining of not getting jio sim started because of they dont submitted their documents as we talk about charges and billing their is no charges of sim and data, calls so in my opinion its the time when people can say KAR LO DUNIYA MUTTHI MAI
