First Of All Say That This kind of First Technology is release now of days.its help that firstest use internet from any where.i bought this sim 2 moths ago.1st of this days its service is unbelievable.but after few days is network service is poor and poor.sometime network down 20 to 30 mins.and every 2 mins to 3 mins call is drop.that is unexpected from this product. because we are highly expected for this product but in talk time section lost my expectation.customer service of this operator is good some times.but inter net speed is awesome highest I got is 1.5MBps which is around 12Mbps.when I bought a sim from care for free.if you want this sim for experience to fast internet then I recomanded to bought this sim from care. or if you think that use this operator just its free talk time that I dont recommend to you.
