Cellular network operator O2 on Friday said its data networks had been restored after millions of smartphones across the UK and Japan were taken offline yesterday (via BBC).

A statement on its website said the 4G network was finally working again, after having been affected from about 05:30 GMT on Thursday.


Earlier, mobile network equipment supplier Ericsson said that an expired certificate was the reason behind the outage, which also created problems in several other countries. Ericsson UK boss Marielle Lindgren said the "faulty software" that had caused the issues was being decommissioned.

Both O2 and Ericsson issued a joint apology to millions of customers hit by the disruption. "I want to let our customers know how sorry I am for the impact our network data issue has had on them, and reassure them that our teams, together with Ericsson, are doing everything we can," said O2 boss Mark Evans. "We fully appreciate it's been a poor experience and we are really sorry."

O2 is owned by Spain's Telefonica and has the UK's second-largest mobile network after British Telecom subsidiary EE.

The company said voice calls were not affected by the problem, but some O2 customers said they could not make calls or send texts, despite having cellular reception.

The outage also had knock-on effects for other services that use the O2 network, such as Transport for London's electronic timetable service at bus stops, which stopped working for most of Thursday.

Vodafone is much better.
You're joking aren't you?! Although I should say that everyone has different experiences and it depends where you live, etc. Had several family members on Vodafone over the years and it's always been terrible for data, particularly data reception more so than the speed. In the end everyone has moved over to other networks, I've been with 3 for 18 months after switching from O2's network, couldn't be happier. Went to the top of Scotland to visit family, a no reception area for most networks in places, I was the only family member with signal and data access.

It was weird because I had just updated to the latest iOS version and didn't notice no data until the next day when I was in the gym. I had no idea O2 was down and was thinking the update had broken my phone. Then I look over on the gym TV see what was happening.

Vodafone is the Verizon of the UK. I’ve tested all the networks and for me it was the best by far. Glad O2 is good for you

30 million total impacted by it and all because some dope forgot to renew a certificate so it expired.....that is just pi$$ poor management

Luckily for me I am on both Vodafone and o2 so minimal impact but it does just show how reliant we are now on being able to access internet services.......rewind 15 years....you were lucky if you could receive texts let alone look at what some dog or cat is doing on insta :)

Vodafone is ranked the worst in the UK for network reliability and speed according to root metrics who are an independent mobile network analysis firm. I was on Vodafone and was paying for 4g but never got it. I could walk for 1 mike in any direction from my house in a major town and get 2g at best. Despite them claiming otherwise. My phone had no issues and was not faulty. Vodafone are just plain useless as far as I am concerned.

Time, because it rules EVERYTHING!
I had issues yesterday, but I just jumped on WiFi but I feel sorry for those businesses affected, which were a lot!

But I’ll stay on Tesco Mobile, who use O2’s network, because they are cheap as and have fantastic customer service. And they do NOT put your price up mid contract and tell you to deal with it... like EE, Vodafone, 3, O2 will..

state of confusion.

From the way I read it, and from experience working with integrating and supporting systems in general, it sounds like this was on an antiquated system (which is precipitating it’s demise). Systems like that might not have the ability to have the cert renewed/updated. This could have been one of the many reasons why it is being decommissioned per their statement.

Cellular service has become criticical infrastructure, so I’m not ignoring the impact. I’m simply speaking to the reason for the outage, that it might have been avoidable, but not necessarily for the reason you are calling out.

We are more reliant than ever on tech, but such is progress.

I’m hearing a lot of people saying “people should have contingency plans in place” or “you did alright without a mobile 20 years ago”. To those people I say what if I came and took that piece of technology called your car? Just took it for the day. Where’s your contingency plan for that? Or can’t you live without that?

Expiring software certs seem like problems where better solutions need to be found (remembering when Apple had some issues with Apps on the Mac App store and peoples apps they had bought just stopped working one day).

Vodafone is very good in Portugal. So it really depends on where you are.

Agreed. I'm with 3 as well and no complaints.

I've been with O2 for about 15 years if not more and never really had any complaints about them apart from them being very slow to roll out 4G when it was new. Plus I do like their O2 "priority" tickets for gigs and quicker entry to venues.

My main issue with O2 is that they refuse to get on the eSIM bandwagon (in the UK at least as O2 in Germany has support for it) meaning the iWatch is only supported by EE and Vodaphone but you need to be on a contract phone with either of those carriers. If I could just add an iWatch to my current set up I'd be in an Apple store in a flash!

Different strokes for different folks - moved to O2 from three last January & found O2 to be shocking - rarely getting a signal & when I did the only way I could get data to work was by switching airplane mode on & off - decided to take a punt on Vodafone & I couldn't be happier - great signal & the customer service was ok as well (when you finally get past the infuriating automation & actually through to someone).

I moved from Giffgaff (O2 MVNO) to Three yesterday, not because of the data, that was just the date of my number transfer. Picked the best time to do it, clearly!

P.S. It's not my fault, honestly! Those Ericsson PAC transfer machines are way old anyway...

I moved from O2 to EE when I got a Series 4 on launch. Very happy. My wife and kids are on O2 still, and I didn't hear from them all day yesterday. Who do I send the thank you letter to?
