O2 in Ireland

[worldspy99]

Have used O2 in Ireland, quite happy with call, SMS and data. Although data speeds were quite slow since I have the TMO international roaming on and we were in a very rural area of Ireland. Quite happy for the most part with the service though. Used it in May 2013 and March 2014.

My experience with O2 in the London area is much the same as yours. I've been with O2 for quite a while now, and for the most part, I am very pleased with the service,

I'm been O2 user for four years. Im really dissapointed with service. Coverage is worst. Internet speed is crap. Since I switched to EE - I'm happy. 4G works in my city.
