I'm on a great sim only tariff. It's an 2009 tariff with unlimited internet. I just phoned o2 to see if i could get tethering enabled and they said no, i have to move to the new tariff. This, in the long run would be much more expensive as the new tariffs have limited internet and it all adds up to be more than what i pay at the moment. Is there any way to get tethering without going a new o2 con tariff? I can see why o2 are doing this - they want to move all the old tariffs out as they are the best ones... Thanks!
