haven’t gone back, but i’ve actually found the opposite, that vodafone is quicker….mad eh….
my mil said the same was with eircom then moved to vodafone and she said that she finds the internet better..
i did find though sometimes slow when with eircom and amazinglyi’d get a call from eircom asking me if i would like to go up a meg or whatever it is….pay more….find vodafone cheaper in the long run… (see how long that lasts)
