Hi, Today, I discovered the network called Ovivo, that apparently costs £0 p/m for phone and tablet contracts in exchange for a few adverts popping up while browsing every now and again. Has anyone had any experience with them? It kind of sounds too good to be true, but reviews seem fairly positive. For tablets, they offer 750MB p/m for free: http://ovivomobile.com/offer/ovivo-for-data/ There is a £20 upfront cost, but a pretty good deal if you ask me. I think they use Vodafone's network? Any help would be appreciated, still haven't bought an iPad Air and this may be a factor that pushes me towards the 3G/4G model.
