First u know there are Two company reliance jio and reliance netconnect. Jio have till no data card customer. Jio is now in testing phase with lyf mobile customer , jio group customer. Reliance netconnect stared upgradation of CDMA customer to 4g. Reliance netconnect now using jio 4g tower .reliance netconnect start distribute new sim once jio will start.... So u r talking reliance netconnect not jio . so I put change name of topic
as per the opinion of reliance store agent, the data card migration to wipod with 4g sim is for Jio commencement. i understood jio is new venture of Rcom.but the 4g sim delivered by the agent told me that this for 4g jio service. and he also mentioned that it will be available from mid august.
