I got my eir phone bill and a shock at the same time. I was under the distinct impression that area-code 076 numbers were ordinary landlines, just not geography specific - in other words the location you're calling could be in Leitrim or Limerick, Donegal or Dublin, but the charges were included in most plans as "calls to Irish landlines". Thanks to Adam & Aoife at eir I was informed that this is not the case. If the number is 0766, it is outside most bundles and is chargeable as a premium rate number. If the 076 is followed by any digit other than 6, it is just a regular non-geo specific landline and the call will be free, depending on your specific plan. 0766 - be warned, I don't ever remember being warned that these were premium rate lines, like 1890, 1850, etc.
