 In a nutshell  

Last updated October 2013

O2 is one of the "big 4" mobile networks in the UK.



O2 was formed in 2001 and is part of Telefónica O2 Europe. It was originally part of the BT group and is one of the biggest mobile operators in the UK, with over 18 million customers. In addition to voice, messaging and data services, it also provides 3G mobile broadband, fixed broadband and home phone services.

O2 launched its 4G service in August 2013, with monthly contracts starting at £32/month and with music, sport and gaming services included. The initial coverage is in London, Leeds and Bradford with a further 10 cities planned by the end of the year. Be aware that O2's 4G service does not support the iPhone 5.

I've been with the same mobile company 18+ yrs but last 5 hardly any cover and none at home for last 5 years should I pay my bill?

Asked by Ger Richards from United Kingdom on 16th Jun 2017

How much does it cost to change from O2 mobile to Virgin mobile?

Asked by Grix from UK on 1st Mar 2017
Pay As You Go only. Also how long does it take?

Why am I being offered a second hand phone when mine wasn't broken? It was in excellent condition only problem was after marshmallow update wifi couldn't be used.

Asked by Mrs Claire Jones from England on 22nd Nov 2016
Did the software update on the 7th October 2016 after I did that wifi would no longer work on my Samsung gakaxy A3. Spoke to o2 who said it was a Samsung issue. Samsung took my phone twice for repair and problem still existed so o2 took phone in the 7th November and they still have it now they were waiting for parts then it was with an engineer now they waiting for parts again now iv been told I need a replacement phone but it will be a reconditioned one and someone else has used it, this is unacceptable as I never broke my phone they are not on it out of order been on phone around 35 times to be told it's a repair fault then repair saying its a customer service fault I was cut off about 3 times in one day.
Never before after 15+ years have I ever had such bad customer service, I am not accepting a tatty phone when mine was in mint condition, I think o2 should pay off my existing contract and let me have a new phone as I still owe £80 on this phone and iv not even had it for over a month yet I'm still having yo pay the bill... Come on o2 sort this out.
Customer service is shocking.
Time to go to another network I think.

When starting a new O2 contract it's best to block all Direct bills to mobile, Premium bar and International Bar to your account, you can always remove the bars later by calling customer service. On new contract or upgrade from 1 October 2018 you can now set a Spend cap at £0.00 to protect you from unexpected bills as you can always change this by calling customer service. Most people on this form don't quite understand what a contract means. You are agreeing to pay a monthly charge for 1 or 2 years plus any extras charges which you must pay. If you cannot guarantee you can afford it for the year(s) don't sign up use pay as you go no excuses please. Look after your phone and insure it, 2 years is a long time paying for something you have broken or had it stolen. I have used O2 (Cellnet), EE (T-Mobile & Orange), Tesco, Virgin, Vodafone and Three for over 26 years and I find now it's easier to buy my phone outright and look for the new SIM only deals. It's so easy to change network with a PAC code and your number changes over the next working day and automatically cancels your existing contract.

Just changed from Vodafone to O2 for £20 20GB sim only which now have Spend Caps on contracts from 1 Oct 2018 tutor Vodafone do not have Spend Caps. (Capped contract) Signal is the same as Vodafone which is the best for indoor an outdoor coverage. My number was ported over the next day and I was amazed it was all finished by 11:00. Phone O2 to set a premium rate bar for all calls and premium texts on my account and I feel overall very satisfied from the service I have received. My family and most of my friends are going to change to O2 when their contracts are up.

if your business happens to be unlucky enough to have between 10 ad 100 phones with O2 business , you will find they refuse to take calls from customers. You can call the general business line, who will say you need the 10/100 team, but unfortunately they can't put you through. In fact not even they can contact the 10/100 team. The best they can do is emaill someone in the 10/100 bunker and ask them to return your call , within 24hrs. Unbelievable, but that is the level of service

Suddenly, you the customer, have become the service provider. It is your responsibility to be available to take their call within the next 24 hours. You will find they will try once and if they don't get you,,,,,, well they tried!!!. Honestly, it is a complete stitch up

it took 4 weeks for me once to get to speak to the 10/100 team and somehow it was all my fault, Me, being the customer.!

We are in the process of moving our 15 phones over to EE. The reception probably isn't any better, but at least when I call I am put through to a human being, and in the case of EE, so far, a very professional person who has resolved any issues we have

We have a full on day at work. I do not have the time to be at O2's beck and call. I want a responsive mobile company who will respond immediately to the few problems we have. We don't need to contact them that often ,but when we do, they need to sit up and look smart.

Thankfully other providers are available. If you are a flat out small business working all the hours, like ours, stay away from O2

I’ve been with all networks I have my personal number with EE no doubt EE are good as golf but their in door reception at my work place was awful and due to nature of my job we don’t get access to WiFi to use WiFi calling. The only network with better coverage indoor for me is O2 so I decided to give it a go.

I took the web chat route and after. Few seconds I was connected to an advisor who was extremely helpful and courteous. Also gave me three months free line rental on thr sim only deal I got disconnected due to a poor connection on my phone I reconnected and it was a different advisor who was as helpful patient and courteous. Offered me the same deal when I explained to her. Therefore so far no issues. O2 customer service is definitely better than Vodafone and Three. As for network coverage and call quality it’s great thr call quality I find better than EE however net speed is slower. 4G coverage is also not as vast as EE but I have a 4G signs, anywhere I go.

I would definitely recommend.

Awful company that knows it owes me £400 and blocked me from FB when asking for it back.

Awful company, I returned a phone to them within the 14 day period. They accepted the return and their system shows they owe me the money for the phone (around £400) but they don't refund it.

I've been on the phone with them many times and they just ask me to wait 5 days and it will be in my account. 5 days comes and goes but no refund.

After many times of doing this over two months, I went to social media and they blocked me from their Facebook page for talking about it. I contacted their CEO, still no resolution - looks like I'm out £400. :(

Worst customer service I have ever encountered in my life don't even bother calling them they are completely incompetent rude and horrific! This is what happened to me:
So I tried to upgrade and add two iPads to my account.
Got hung up on twice
Called 6 times for the link when I eventually finalised the deal they got my email wrong and the level of incompetence was ridiculous they couldn't take down the correct email.
Eventually got the links then there was a system failure couldn't get it.
Then got hung up on again.
Eventually went into store and got a worse deal thanks o2.
Then I get a text the day after saying my order has been dispatched I have no idea what was ordered. I walked away with everything at store.
So begrudgingly I called the customer services again they told me someone had ordered something in store on my account. IT WAS NOT ME. They told me nothing could be done unless I went into store. It's my mothers birthday I can't go into store Sammy advised me I had to go and she wouldn't look into anything until I proved that wasn't me. She was HORRIBLE.
I then called back and spoke to Marium who was lovely and cancelled the fraudulent order.
I am disgusted with the customer service Sammy didn't even report it as fraudulent she advised me she had no idea if I was telling the truth that I might have gone in my lunch break! I don't work anywhere near the store. She wouldn't even tell me what actual store it was she just said it was the last one I went into. Well that could have been any because IT WASNT ME.

In short I think o2 customer service is awful. I was over charged on my first bill from o2 due to being charged for multi media messages (many people have had issues with o2 and charging for MMS) o2 promised to reimburse some money which was never written on my customer file notes to confirm they had authorised giving me a reimbursement and after not giving me the money back they then after several lengthy conversations said they would give me a reimbursement which actually never transpired so now I am totally frustrated and can't be bothered chasing them! I never ever had any issues with MMS charges from Vodafone coz they don't charge for MMS and they always professionally dealt with me.

Dont sign up with O2 until you read this!

In my life as an adult, O2 is the worst phone company that I've ever used, their network coverage is very very very bad, their customer service sucks as well and communication between the department are not even effective, and they have customer service representative in india, south Africa and UK and other countries but I had to go through the painful frustrating task of dealing with call agents from these 3 countries, and if you're on the phone to them make sure the bad network dosnt cut off the call, because if you call back another agent from a different country will pick and won't even have a clue what you talking about because the previous agent didn't leave notes. When a company called mobidoll started scamming me, O2 played along nicely from June 2016 to October 2016 I had paid close to £200 this is money I paid ontop of my line rental and device fees, (money paid to mobidoll) O2 promise me in August that, they'll rais a dispute on behalf, we'll, that never happened after about hundreds calls back and forth with long waiting times and explaining myself over and over again I almost went mad from frustration, well not only did it put a massive impact on my credit score, I ended up paying every single penny before the barring on my phone was removed, they promised not to charge me once the dispute is raised, they even made me pay late payment charges, well the last payment I made was in October for £34 which they told me my problems are finally over, WeIl right now my bill came and they're still charging me late payment fees, it very sad to rub money of innocent vulnerable customers. This is a good confirmation that O2 are horrible, they don't care about their customers and teamwork hand in hand with these scammers which makes them scanners too, there's a lot to say which I can't post it all here, my heart is really broken because friends warned me about O2 before signing up with them. I keep paying money I don't have every month, extra money ontop of my tariff and they always give me explanation that don't make sense, I can't wait for my contract with them to end and be free, I'm really stressed about all this. I won't ever recommend O2 to anyone at all.

O2 recently outsourced their mobile customer service to Capita, who offshored it to South Africa. I have no problem with offshored call centres other than their total and utter lack of power to do anything useful when something goes wrong other than 'fill in a form'. Or if you want to escalate, fill in another form. O2 have effectively driven a wedge between the people who handle the call and the people who fix problems and as a customer this is for the first time in a decade making we seriously think about leaving O2.

You took the words right out of my mouth! I've had 2 contracts with O2 since March this year and 7 months on have yet to get network coverage or signal anywhere inside or outside within an area of several miles around my home. This is a familiar story from many other O2 customers I've heard as well as some Vodafone users too I've spoken to (and as it happens Vodafone share the same ariel O2 uses!! And thus also same issue they refuse to admit to or acknowledge!) After numerous complaints alerting O2 to the issue,I've been told that unfortunately 3 if their masts are not positioned to include my home address location and cannot be adjusted to do so meaning no improvement should be expected in future either. So for my troubles I've been offered £50 CREDIT toward my bill so generously making up for the 7 months of the service I've been unable to use which I've already paid for and what remains of 2 24month contracts I'm trapped in paying for the service I'll never be able to make use of for the full duration of both contracts!! Wow I'm Speechless.

After they failed to collect their money via DD from the new bank account (which they confirmed they had on screen in July) for two months and three calls from me to find out what problem was, they stopped my phone. After 1hour and 10 minutes to get through to someone in Jo burg, I was told they had tried to collect the money but my bank had refused it!. They lie, they dont care about customers (their staff turnover is so high they know they wont be there the following month to answer any questions) and they operate on the basis of we will bully you into submission.
I have since cancelled all payment facility to them, told them if they want any outstanding money (they are very quick to contact you if you owe them!!) they can take me to County Court. I am perfectly happy to let a Judge see all my calls to O2, their texts, recorded conversations, bank details etc and let a sensible legal person make a judgement over who is in the right.

Its a shame that All O2 users couldnt get together and all stop paying - then watch O2 go into freefall. All it takes is a little care and some genuine customer service to resolve these issues.

I joined 02 when I was 15, I have been a loyal customer for 8 years. Over the past two years I have had the worst experiences with 02. They issued me a contract with a special deal for being a loyal customer. Only to find out they had filed me into two more Sims, which they had advised were family and friends without stating I would be the one paying for them. Why would one person need to have 3 activated sim only contracts? That was cancelled taxi!y and the charges were reversed. Then last November I received a sudden bill for 125 pounds. Baring in mind the contract come with unlimited texts and 300 mins call allowance for 10 pound. However I went over by just under 200 minutes and they sacked another 115 pounds on top. Rediculous!!! I then lost my phone the following December. The security questions were ridiculous to try get help with my account. Relied on memory of an elephant who has nothing else to do with their life but watch their 02 account. One of the first rules you learn about questionnaires is not to rely on customer memory. It is now the fifth month of not having this phone. I attempted to get the contract cancelled five times. In January I managed to cancel the account but quickly learnt from my next bill that this wasn't done. I was told my phone account had been cancelled and not the payment account.... wait a minute, I thought this was the same thing? Nevermind that, I carried on presiding the cancellation of the account. Yet again the stupid security questions. The long process to get anything done and a 02 guru saying they could help. Finally today I have been able to cancel and have it confirmed however have to pay another bill. By that time I would have paid 6 months of contract I having used.

Yet alone to mentioned, when they were getting on good I was a student with a budget. I would receive the most ridiculous bills each month which now have me sitting in a planned overdraft and trying to get the paid off. They are a greedy network with shot signal and really long processes to get anything done. They are a financial burden and risk you take on. Beware, they do not value their customers and unfair . The only part I think is good is their gurus are very friendly and patient. Feel sorry they have to be serving in this company and performing ridiculous protocals. Why would I need security to cancel an account?

Three days ago when I checked my online bank account I noticed the balance was going down very quick.

I then checked my messages and emails and there isn't any information about that outstanding charge at all. I thought it was probably somebody else using the title of O2 and called the O2 customer service. And it was for the over-allowed minutes. My friend using 3 company has their minutes automatically stopped once it's reached the allowance and I get nothing, nor a near allowance notice and no notice even once I have been charged over a hundred pounds! It's just been charged secretly and this is just like a thieve?! When I suggested the customer service to do reminders or auto cut they just don't like it and start persuading me to unlimited minutes.

I had exactly the same problem . Was on a ten pound contract for being a loyal customer of 7 years, with 300 minutes included. I went over by 200 minute and they bills me for 125 pounds with no notice or warning as it was accrueing.

O2 seem to think its OK to renew contracts for you without your permission, that combined with some of the worst customer service I have ever experienced.
If you ever find yourself considering getting a contract with them know you would do better simply punching yourself in the face every day for a couple of years.

Train your sales team to be honest and not lie to your customers. Very dissatisfied by the information. Complete lie and not accurate information. I cancelled the contract, didn't pick up the iPhone. You tricked me into signing up to another tariff. Called 6 times to resolve the issue. Still not received the order cancellation confirmation. Now that I have my pac code glad I am leaving a dishonest organisation. You should be ashamed you lost a customer of more than 10 years. Extremely unhappy.

The service in general is poor! My phone the signal the waiting for a fix or solution the crass excuses and the biggest issue of all! O2 if I don't have phone service for a week no reduction or refund! But 1 minute over my agreed tariff then its flood gates open for hitting me with additional charges! Why? I have had no phone service for practically 1 month! Apart from wifi or data roaming! O2 solution it's your sim mate!!! Now new sim no different!!! I go abroad all of a sudden I have a signal!! 17 quid extra on my bill which again I do not understand!! It's all unlimited yet the tariff I chose was 18 for service 15 for phone and yet it has never been 33 pounds in total although I have unlimited everything!!! Total con total rip off from a company that once cared but know basically says I have your money now get lost.

There was a brief foray with VirginMedia a few years ago with one contract but their mobile phone customer service was atrocious so the contract was not renewed (I am with VirginMedia for landline, broadband and TV and I have had no issues). In all that time I have always found O2 to be helpful and courteous when I have contacted them and quickly resolved any issues.

DON’T FALL FOR O2 ATTRACTIVE ONLINE OFFERS! Unfortunately it is very likely that you’ll be screwed, just like me. I’ve ordered online a Sony Xperia Z3 at a competitive price with the help of an advisor via the tchat. It was supposed to be delivered the day after. Two weeks after and with the MONEY DEBITED RIGHT AWAY still no news at all, 0 emails, 0 papers to say they came and no one was home, 0 calls, 0 email alerts or something. I had to call them 3 times, plus call UK mail as I was asked by O2 to finally find out that they tried to deliver it 3 times and then they sent the phone back to O2. If you don’t work or spend the whole day home you will be fine. But if as me and as most people your are not home during the day, you are very likely to have the same issue as me. They don’t give a time span within which they would deliver it. So unless you have a few days off to take to make sure you are home for your delivery, it will be sent back to O2 without any advice. I finally went to an O2 store and explained the problem to a nice advisor who tried to help me by calling O2 customer service, which is actually not at all a customer service because their only reply was: “Too late Miss, we can’t sent it back to you. You’ll be refunded but if you still want the phone the only possibility is to re-order it and now the price has gone up by £120. Bye!” Now this is one week after, and STILL NO REFUND… 3 weeks lost, no phone, money debited… And this a famous company…?

Been with O2 for over 7 years and the customer service is miserable. Unable to take mobile phone calls at home with no signal, need to go near a window to carry on telephone conversation. The monthly direct debit contract is 24 months and very expensive compared to other networks. The 3 G signal is never available, and yet O2 is eager to launch 4G.
I agree O2 was very good in the past, but now its customer service and signal have both deteriorated badly. I have no intention of renewing my contract after over seven years.

The latter, I blame on their eagerness to forge on with the lucrative 4G market whilst letting the 3G network suffer as a consequence.
An example of the signal issue is this ... last year, in my kitchen and lounge, the signal on my phone was (to coin an old CB expression) blowing the windows out. It was terrific. Today, I am lucky if I get one bar. Nothing in my home has changed and I have tried several different phones but the issue is the same.
O2 can't give me an explanation for this, stating that there signals are working well... This really doesn't give me confidence to renew my contract this October.
In my mind, O2 have lost the edge on both quality and price which is a damn shame as 12 months ago, there were so dog!!

Exactly O2 has lost it's Mogo - the shop assistants are half heated about helping & I made the mistake of going into there shop on Camden high st : I have been with O2 for a decade yet because I got a new number two years ago they only have records of me being with them for 2 yrs : I wish I had let my contract just end I got talked into a rolling sim 4 different O2 reps told me different things not once did they say this rolling sim is a upgrade when I was offered it : u can tell they r happy 4 people not to be to aware of whats benefits there coustomers more what they benefit - yet there is a lot of competition out there - the last good thing priority moments yet half ok

O2 used to be good, now going down in reputation and service, with poor customer service,expensive plans/handsets.Without the customer's knowledge they appoint Azzurri to take charge of accounts, so the customer is pushed from pillar to post for any issues arising from mobile phones. With faulty handsets, it took O2 more than 5 weeks to send re-furbished handsets which were also faulty, with customer at the receiving end of this miserable service. PLEASE AVOID THIS COMPANY AT ALL COSTS, THEY TREAT LOYAL CUSTOMERS OF OVER 7 YEARS VERY SHABILLY. I WOULD NOT RECOMMEND THIS NETWORK PROVIDER TO ANYONE.

what has happened to o2? used to be good now going down the pan with shoddy customer service, expensive plans/handsets. heard a rumour of a merger with three, if that's the case i'm off, three are a company worth the watching. Shame as they used to be good.
