We've stopped using campsite WiFi. My wife has a SKY mobile with gallons of Gbs and I have a Popit mobile with 100Gb per month. So not necessary and anyway can watch iPlayer, Channel 4, ITVX etc, abroad when using UK registered mobile, which you can't using campsite WiFi without a VPN - and they don't always work. I should add that we've always been able to get a signal on our mobiles, except on one occasion in Spain earlier this year when there was no mobile signal whatsoever. So for us MiFi not worth the outlay and campsite WiFi not needed.
