Well that's unless something changed recently, I'm pretty sure they've been on O2, Three, EE and Vodafone at some point. The 5G plans were indeed exclusive to Three and EE and very expensive. I personally haven't bought a phone on contract since the HTC HD2 ages ago so I don't really pay attention to these.I wasn't aware of that. Being exclusive to Three and EE has meant past OP carrier deals have been stupidly overpriced.
