  • timporteruk Tim Porter (@timporteruk) reported

    I ask “Why?” when it’s been established the hub is not the issue. He informs me so that they can do further checks. As of today I’m still waiting to receive a text message from @ThreeUK and this is truly when the penny drops.

  • brndnxiii brndn (@brndnxiii) reported

    @ThreeUKSupport I live in NW London and I’ve been experiencing a disastrous 4G connection for a couple hours. I can’t even open any page on Safari and most apps won’t load due to bad connection. What’s happening?

  • pickled_tinker Grody (@pickled_tinker) reported

    @ThreeUK you should honestly be embarrassed about your network's performance!! 3/0.2 at 2000ms pings is not only atrocious, but makes O2's ****** 3rd world network stomp all over you. SO23 9LJ Has been **** since the very first day. @Ofcom should forbid your 5G rollouts.

  • DannyTh46002503 Hands0n (@DannyTh46002503) reported

    @ThreeUKSupport Jonathan, see previous. It is intermittent. Now working at 12:22 when I flipped back to 3 MBB to check. As it affects FQDN and IP address suggests a route issue somewhere in 3. Maybe one leg of a diverse route. Can't be Internet if other CPs work OK

  • jonathanfaiman Jonathan Faiman (@jonathanfaiman) reported

    @ThreeUKSupport Thanks. But it’s still down and we have a strong signal from mast 85506. So we must be part of the small number of customers who are into day 3 of a network wide problem with mobile broadband. And other than you care, we haven’t been told anything.

  • IanSwine Ian Dixon (@IanSwine) reported

    @ThreeUKSupport No. Because my phone is locked to another network. I bought the sim for a dongle
