    @jessklingelfuss @ThreeUKSupport @O2 It’s awful all over the place, in my opinion network is congested, too many phone companies with too many devices on a substandard network. If your not happy maybe retweet complaint using BBCWatchdog, WhichUk and ofcom tags. Im on a mission go get them to fix it or own up!
