Compare to other cellular providers jio give net for low expense but poor connectivity .Now they provide daily 1Gb net for three months with just 309rs, we can get internet with low expense but its main problem is poor connectivity and some times very slow and also provide free calling but calling also poor but it can provide good experience.But one disadvantage is in jiofi calling service is very bad, we can do free calling by using its voice call app but calling connectivity is poor
