    @giffgaff hi! I’m buying my mother a phone for her birthday and want to get a giffgaff sim to go in it. Went to order one on your website but whose name, email, number etc do you need? Mine (buying) or hers (customer)? Thanks!

    @giffgaff I ordered the Huawei P30 yesterday and you guys have sent me the P30 Pro.. My moral compass feels bad for accepting this, please advise :)

  • BradChanner Brad Channer (@BradChanner) reported from Cardiff, Wales

    @teamIPSE Without a doubt! And phone signal! It is appalling how bad the signal is in parts of the UK outside of London! I am 4 minutes from the Cardiff city centre with no signal! #howareyoumeanttorunabusiness @o2networks @O2 @giffgaff

  • BradChanner Brad Channer (@BradChanner) reported from Cardiff, Wales

    @O2 This has always been an issue. We are with giffgaff whom I believe use your signal. I have tried everything. I have even bought a booster, but the reception coming into the booster isn’t enough to even make the booster work. Very frustrating. I have to sit in a window 4 reception

  • carolinejoyw Caroline Joy Watson (@carolinejoyw) reported

    @giffgaff Hi I’ve tried both the app and the website. My card details are up to date and I usually have a recurring goody bag. Think something is broken as I’ve not been able to add credit all week but thought it was because I was abroad

  • katlvsjames kirsty mccaw (@katlvsjames) reported

    @giffgaff I've had no signal since half past 11 this morning it's now 8.10 and still nothing . What is going on ?

  • Robdeespania Robert Tkaczyk (@Robdeespania) reported

    @giffgaff Hi Jade, my final giffgaff goody bag finishes in 1 hour and I’ve received zero real help.

  • BenjaminEHowe Ben (@BenjaminEHowe) reported

    @alice_fearn @Jamesontweets @ThreeUK If you're not sure (and I don't think anything is certain when it comes to mobile signal!) then you could always test it using a Pay As You Go SIM? And you can be sneaky with "virtual" netowkrs – e.g. Giffgaff and Sky use O2, Lebara and TalkMobile use Vodafone :-)

  • 1Joshwa 🚑🌈Josh 🇪🇺👨‍⚕️ (@1Joshwa) reported from Patchway, England

    @giffgaff your 4G full bar signal doesn’t even load a webpage 😩 #giffgaff

  • katlvsjames kirsty mccaw (@katlvsjames) reported

  • runningrobderby Rob Turner (@runningrobderby) reported

    @giffgaff Wow, turns out it could be a mast issue in Keswick, which they have no control over , not even able to escalate or inform @o2 looks like we'll be switching mobile providers
