Dublin Wireless Solution

My company is relocating an employee to Dublin for a few years. The relocation company has indicated getting a landline at his apt was too expensive (not sure why). Thus, my assumption is that wireless is the next choice (broadband is weak at his apt so Skype is not a solid solution). An hour or two of calls per day will be to the US, another hour or two will be in Europe and Ireland.

Can you recommend a wireless provider or a solution for this need?

thanks
