Jio is very good sim launch by reliance company . I like it very much. I want to convey my message to very body who do not know about it . The company has scheme that refer to all 4g phones . The sim is selling free by any phone shop near your home . It gives free data or net to 31st march and calls for life. It means that you can use unlimited data and phone calls till 31st march. Jio also launch a jiofi device which is use as a wifi and it is useful in very 2g, 3g or 4g phones. It is very good scheme that made each and every person with net within their phones . Please don not use any other sim please buy jio . So I think my review gets successful.
