    @O2 hey why didn’t I get the #EmergencyAlerts today? I know @ThreeUK had issues but heard nothing about @O2

  • TwoOaksFarm Dave Hartles (@TwoOaksFarm) reported

    So appears you only get an emergency alert if you get 4g or 5g signal. @O2 only deine to let me have 1G in a small corner of my garden, or wifi calling, which means I'll be killed to death before getting an alert.... which is nice...
