I'm curious what is the average revenue per GB of 4G (or mobile data in general). That the entirety of their 4G network bandwidth usage is about 30Gbps (averaged over the month) is slightly surprising to a not-mobile network engineer such as myself.
In the UK Vodaphone offered free 1GB of 4G in september to me and I assume other subscribers. I wonder if that was to help boost these numbers, or was just marketing.
