As we all know after 31st march 2017, the jio services will be charged, user will have to recharge with ₹303 to continue get the 1 GB data daily and unlimited Local + STD calls.
There are more other recharges available, but the main point is JIO only supports LTE and VoLTE devices it means if your 4G phone has broken or not working you can not insert you JIO sim in a 2G keypad phone.
Airtel and vodafone is giving the same offer like but price are a little bit high, not that much hifh mean where JIO recharge is ₹303 for 28 days airtel recharge is ₹348, but you will not get any free SMS or premium JIO apps services like jio.
So before choosing any service please think and yeah one more thing, please recharge with ₹99 before 31st march because you want to continue with JIO you will have to do this recharge to get JIO Prime offer.
