Recently I brought the sim frok a jio mini store.it can be used only 4g phones.it will not work any 3g phone.the sim is produced by mukesh ambani.the offer of the sim is supper.they are giving unlimited 4g data for 3 months in any 4g phone, unlimited voice calls r lifetime.12 months of free 4g data for lyf handset users and free voice call for lifetime.
the Customer service of the sim is not so good.because if u call to its customer care service.it takes a lot time to take the call.once I call them an they took 45minutes to take the call.
the speed of the net is cool.but one problem I am facing with the sim is.if I call someone.he cant hear my voice clearly.thats for network problem.otherwise the sim is super cool.friends, if you are using a 4g phone, then bring the jio sim.it is awesome.
