    @O2 Can you advise if there are network coverage issues at the Creamfields venue? No signal available whatsoever for a family member. Trying to understand if there is a fault and if it will be rectified. Thanks!

  • ConnaireMcG Connaire McGreevy (@ConnaireMcG) reported from Burren, Northern Ireland

    What is the story with the @O2 signal at Milltown Industrial Estate these days. The last few months since they “upgraded the network” it has been worse than ever. Getting very hard to run a business in the area without mobile signal.

    Question? @O2 phone signal been iffy at home for while, drops to 3G, doesn’t always connect on calls but within a mile radius of home will not connect to car Bluetooth…. Odd!! Would this suggest interference from something and how do I report?
