.@ThreeUKSupport the broadband is hardly working videos are buffering, still no 5G only 4G, games are unplayable and it just randomly cuts out. 5G on my a phone is down to 2 bars and is slow! We literally live down the road from a mast, it’s not working!

We are pleased to announce the successful completion of the merger of @VodafoneUK and @ThreeUK. #VodafoneThree will deliver a vastly superior mobile experience for millions of customers and businesses up and down the country.

“These things won’t fix themselves”. Well @ThreeUK seem to think that just talking about fixing a network outage will fix it. No wonder it’s taking longer than expected to fix it, just yapping about it never achieves much.

Anyone know if @ThreeUK has gone down. No service at all

Do not EVER sign up for @ThreeUK it’s hands down the worst customer service I ever experienced Full scam company

Looks like @ThreeIreland is down nicely in at least Dún Laoghaire–Rathdown, had no mobile data for a while (with 5G gone) and now it’s just plain no bars and No Service, cheers @ThreeCare

2nd time in a few days @ThreeCare Mobile broadband is down. 🤬😡

Why has the network gone down twice, Friday 11th for 2 hours and again today just now? And yet it isn't reported anywhere? @ThreeUKSupport

.@ThreeUK you have blood on ur hands why is my data not working i just had to ask a grown man to hotspot me

Anyone else been stung with a £5 coffee because @ThreeUK rewards codes are not working?

What's happened to the #5g roll out in #Cornwall #Kernow?? Sick of being tied to EE down here but no one else does 5g? @VodafoneUK seems non existent, @ThreeUK seems a little better on their coverage checker tbh.

Why is my network down again? Why cant i make any phone calls? @ThreeUK #ThreeUK

The 5G broadband is flat down for the last 3 hours in Central London... what's happening @ThreeUK @ThreeUKSupport ?

Morning folks @ThreeCare. It seems signal is down in D13 area (I'm in Belmayne). It's affecting my mobile and broadband. Are there any known issues in the area? Thank you

Is @ThreeCare down?

I see @ThreeUK is not working for voice calls. Again. I do love this being an on and off issue for the past week. It's so fun.

Three (3) network still down, losing business calls, this is awful service. @ThreeUK @ThreeUKSupport

The worst thing about @ThreeUK network being down for voice for almost a day, is their downplaying it as a 'small' % of customers, when it was nationwide and everyone on their mobile plan. A fine example of a business with low integrity.

Any compensation following yesterdays outage of not being able to make phone calls? @ThreeUKSupport @ThreeUK we do pay you for a service and you didn’t provide that!

For those of you not in the UK, @ThreeUK has had a network outage since 1 PM yesterday. Service has not yet been restored. (My phone uses the Three network). I am wondering whether it is an intentional distraction. @HowardSteen4 These are the times I wish I had greater reach.

Just read that Three was down again today. So that's why I couldn't make or receive calls, YET AGAIN. Honestly becoming a joke. Worst phone company I've ever been with!! What exactly are we supposed to do in case of emergencies then @ThreeUK as someone who's suffering with 1/2

Severely disappointed with @ThreeUK. Needed to call 999 Emergency service tonight for an ambulance. Could not get through to your network being down! I understand that things happen but no access to emergency services? Where is your resilience! Really dangerous!

Cheers @ThreeUK @ThreeUKSupport whole work day wasted and info missed cause of your outage

Do we all get a refund for the outage today @ThreeUK @ThreeUKSupport #NoPhone

3 network still not working. Absolutely useless @ThreeUKSupport. If you don’t sort out the issue tonight, I will be switching to a different provider tomorrow morning. 😡

Anyone having a problem with Shell Broadband this evening? Can’t even phone the @TalkTalk helpline because of the @ThreeUK outage. 😣

How has it not made uk news on the tv that the three network is down since 1pm it’s now 930pm with no phone connection make of receive call @ThreeUKSupport @ThreeUK

So @ThreeUK still down (off since lunchtime) and no help from @ThreeUKSupport Very poor, I’m not impressed #cantmakephonecalls

Come on @ThreeUK, your service is *still* down. An update would be good.
