Three goes to zero as UK mobile provider suffers voice and text outage

(2025/06/25)


Britain's Three mobile network has suffered a major outage, with voice calls out of action and limitations on texting.

The problems kicked off early on Wednesday morning, with Three originally reporting that voice services were lost, but data was still working. This was later [1]amended to say text messages were affected too, but data transmission remained operational.

"We're continuing to work on an issue affecting voice services which started earlier today. A small number of text messages are also being affected by the issue," a spokesperson told The Register .

[2]

"Data services are working normally, so calls can be placed via third-party messaging apps. We know how frustrating this is for our customers and we apologise for any inconvenience caused."

[3]

According to the [4]Downdetector map , the outage is hitting across the UK, with Wales and Scotland hit hard as well. The company has not said what caused the outage, but at least third-party messaging apps are able to route around it.

Earlier this month, Vodafone and Three [6]combined to form the joint-venture VodafoneThree, pledging to spend £11 billion ($15 billion) on network improvements for faster data and improved voice calls over the next decade. That doesn't seem to have worked today.

Three fiddy

elsergiovolador

If that happened when I had Three SIM card, I wouldn't have noticed because I had no reception anyway.

In London.

Re: Three fiddy

VoiceOfTruth

This.

A few weeks ago somebody commented about the (paraphrased) '100% network coverage in the UK', saying it's not true. Using Three in Foyles, slap bang in the middle of the West End, we're talking dial up speeds. Sort of usable for WhatsApp text messages, but that's about it.

I love being with three! It reminds me of my times in remote, desolate parts of the world, totally disconnected from civilization. And all this from the centre of Surbiton

Empire of the Pussycat

Yep, I dumped Three, central London, no signal.

3G Shutoff

Steve Davies 3

I was in West Wales a while ago and there were areas where it was 2g( on Voda) or nothing yet they want to cut 3g... I hope that Vto oda and BT are going invest before the whole area becomes a mobile free zone.

If they don't then there will be a lot more unhappy punters than with the outage today.

Why No Notification?

Gerry 3

Haven't been able to make or receive calls all day.

Three claim that only "a small number of text messages are being affected". So why can't they be bothered to send a text to all customers warning them that they can't make or receive voice calls? At least people would know it's not their fault and then they might be able to make alternative arrangements.

If you're on PAYG and use Three largely for incoming calls (especially in the EU, where roaming charges don't apply) you probably panic that you've lost your number because you haven't topped up or made a chargeable call recently. You wouldn't just assume the whole network has fallen over.

What he said ^^^ Three used to be a good company. Daren't call customer services as you get complete muppets who barely sound like they know what a mobile phone is.....

Re: Why No Notification?

And now they will be 'improving' their customer service as they get onboard with Vodafone. Apparently, they are taking on Vodafone's billing and account management methods and procedures - so victims of Vodafone's customer service when billing goes awry will be pleased to know they will no longer be alone when it comes to being shafted...

My wife and I both run our mobiles via Three. Mine went out of contract earlier this year. After the previous outage and the 999 fiasco (on top of my never wanting to be a victim of Vodafone again), I resolved to take both away once my wife's account goes out of contract.

Wife's account goes out of contract in two days (Friday)...

Both numbers will be ported away. Where? Anywhere not associated with Three.

Anyone else in a similar position might want to learn from the mistake we made at the start. NEVER operate his and her mobile accounts with the same network. All it means is that if YOUR phone goes down, so does THEIRS (single point of borkage). We won't be making that mistake again...

My only regret is that their customer service structure is such that it is almost impossible to speak to a living being in order to let them know why we are leaving. Maybe that will sink in if people vote with their feet.

Re: Why No Notification?

It's always the same - "*some* text messages", "*some* of our customers *may* be experiencing", etc.

It'd be refreshing if, when these things happen as they do, they just put up a message saying "OUR NETWORK IS FSUCKED RIGHT NOW. We're trying to fix it. Apologies."

Wondered what was up...

abend0c4

I'm on Smarty, Three's unloved stepchild, and am currently roaming. I wasn't able to make calls ("Sorry you've not been given access to this service") until I turned off VoLTE - though whether that would be a fix if you're not roaming, I'm not sure (it certainly wouldn't help if there's no 2G or 3G coverage).

I did get notified of voicemail but couldn't retrieve it, but when trying was instructed to "call from your phone and set a PIN". Needless to say, I was calling from my phone and had previously set a PIN.

Can't help feeling there are too many layers of (fragile) complexity.

It's also very annoying that incoming calls get ringing tone when the target phone won't be making a sound.

Anyone calling an elderly relative living alone might assume the worst and set off on a long and unnecessary journey, or have to disturb a keyholder or the emergency services.

Time for dozy Ofcom to set some standards.

Chloe Cresswell

Friend is in a MVNO who use the three network, took his work phone down, Luckerly he has his shop VoIP provisioned on his phone too, and most of the time data was working so he could use that to call out from his mobile!

Two phones, both Three

CorwinX

Mine came back up for calls around 16:45.

Data, browsing etc, was indeed unaffected.

Not sure about SMS because a couple of people I texted haven't got back to me yet. Can't be sure my texts got through.

Re: Two phones, both Three

PCScreenOnly

Misses phone is back now, but had to have a restart - thanks to a 18:45 update on the ID site

Re: Two phones, both Three

ChrisElvidge

No data interruption here.

Don't use calls/texts much.

Wow!

G R Goslin

Wow! Am I glad I left them last week. I was with Three for years. Finally I got fed up with the monumental price hikes and the utter destruction of their once good customer support, and moved.

Re: Wow!

Asked for a PAC and got ~£5 reduction on unlimited data package.
