It’s been six months I have been using jio 4g. I got the sim with my new samsung j5 mobile for free. In first three months it’s speed was outstanding with unlimited net usage and 4g speed. As the demand for jio 4g sim increased its browsing speed started getting slower and now afeter 6 months I am like why, I have been using this sim as its network problem is getting more worse.After its plan would end, I would get a new 4g sim.
