Virgin, Lyca, Play, Era, TMobile, Nju, what else?
Orange also & Plus GSM
Virgin aren't here though, never heard of Nju. Does Lyca really count though, that's mostly for international calls. Which I don't really understand why people would use when they can use skype/google hangouts etc.
Era is now Tmobile
Thing is, those smaller ones like Heyah and Play actually piggie back on larger networks. Heyah have no masts/signal receivers/reflectors of their own, they just buy large lumps of airtime from Tmobile (I think)
Play have an infrastructure, but they will use others's towers when necessary.
Play are the cheapest, but their reception outside of towns and cities is truly awful.
Heyah are the spawn of Satan IMO, constant spam text messages and calls. They recycle their numbers quickly too, I think if a number hasn't been topped up in 6 months, they disconnect it and resell it. I was getting phone calls for about 6 months from banks looking for the former owner of the number, until I changed to a pay monthly phone.
