I'm not a sales associate, do some groundwork on their site to compare features; especially with other providers, as I know there are plenty out there.
My plan is free, and I've blocked all of China and Singapore from UBBDev, to answer your question on geofencing; they also offer premium features which I cannot attest to as, again, I'm on their free plan.
And "is it fast", have you had any problems accessing any of my sites (other than when Groupee takes the UBBDev server offline for occasional maintenance)?
