Re: The turn of the millenium called...
I'm on £15/month for 30G (but all hotspottable). Since most of the data gets used at home on a real computer with a real keyboard (phone k/b is too fiddly) the extra £3/month for unlimited (but all bar 30G of it only usable on the phone) wouldn't really be worth it.
For those looking for the £15/month SIM, you're out of luck. Three no longer offer it, but if you already have that package you can continue with it.
Oh yeah, I only get 200 minutes of talk time, but since I'm an antisocial bastard and never call anybody, the unlimited talk time for an extra £3/month isn't much use either.
