I am a gio user from last 8 months this is the best network I used till date it actually works everywhere where idea n vodafone doesnt gets network gio did a very good job in tems of network n net is super awsome n rates are also pretty good as compared to idea n vodafone now currently I m on jio preview offer which is valid for 3 months guyz dye to gio other networks rate has fallen down otherwise till date we would hav spent 250rs per 1GB. Which was not possible for a middle class person but now no worries gio is here pretty impressed with jio calls gio to gio provides HD voice calls for free recently m facing little problm in callong which is not a big issue ovrall every person should hav a gio sim who has 4g enabled smartphone:)
