Vodafone Supernet 4 G is slowest and weakest network. I am useing vodafone SuperNet 4G last 5 months.vodafone 4G gives me some offer but they are very costly. its internet speed good some times. I am also using Jio 4G. Jio provides Summer Surprise offer. In summer Surprise offer Jio give us 3 monts free call, internet, sms and far more services but Vodafone not provide any offer. I think jio 4G is better no dought but in calling purpose vodafone Supernet 4G is far better than jio 4G because jio have many call drop issues.
