I have purchased a jio sim when it was on preview offer only on Samsung 4G phones & I must say I was hugely impressed with its free calling, internet & Sms.
It was proving to be a game changer at that time, but as soon as it was rolled out to all handsets it has become a pale shadow of itself, its internet speed is now working like a 3G or sometimes worst than 2G eeven before you exhaust your daily data threshold pf 4GB.
Even worst is its calling which is not all ready to connect before you dial a particular number 4 to 5 times & just forget about your calls getting connected to Vodafone, Airtel or idea, its jio 4G voice app is not ready to get Online also.
I dont know what is the problem with it, but surely itvis proving out to be a headache nowadays & I will surely dump it after 31st December
