Vodafone Offering Free Data to Subscribers on SIM Upgrade Vodafone has given the moniker of SuperNET to its 4G service, and the company has announced that any existing subscriber who upgrades to the 4G SIM will get 4GB data credited to his or her account. This means that as soon as a subscriber updates their SIM card to a 4G one, they will be able to use the data to browse the internet, watch videos and make use of the Vodafone 4G network. Also, if they have a VoLTE compatible phone, then they will be able to enjoy VoLTE calls as well which provide higher audio quality as compared to standard phone calls which happen over the 3G or 2G network. Further, the improved 4G speed will let you access other benefits which Vodafone has been offering to its prepaid and postpaid customers. You will get access to Vodafone’s range of content which it is providing on the Vodafone Play app. Also, other services which might not work on a lower speed network like video streaming will now be accessible to you with ease.
