O2

 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.

Most of the advisors are useless and few of them seems useful but after few days you realise that in fact they are liars. I have been waiting now for 3 months to get a voucher for referring a friend and I don't think I will ever have it. But I had the "pleasure" to spend 2 or 3 evening with the customer service on the chat...for no results, but Dan, Kevin, Bill, Jasmine...I know them all now!!

I have had a contract with O2 for many years but the price just kept going up. I thought I would try and discuss this with customer services but after half an hour on the phone of being told I was in a queue I decided to drive to Cambridge to discuss face to face in store. There were 4 assistants and no one else in the shop but no one wanted to help me. I was given a phone to speak to customer services about terminating my contract/taking out a new one. An hour later I left the store. I felt I was treated very poorly NO ONE could be bothered to help me .
I drove to Bar Hill, went to Tesco Phone Shop who were helpful,polite and at least seemed to care. I wouldn't ever recommend 02 to anyone.

we took a 24 months corporate contract with O2 in 2013 for 14 handsets. Their network coverage in Hampton, Walton-on-Thames and Weybridge is very poor. There is either no coverage or calls drop with no reason. Other times the voice quality is very poor.

There are also problems with mobile data on 3G network.

The only good thing about them is that they have hotspots in shops and town centres. So I can connect to internet for emails and other business use.

Avoid O2 at all cost. The UK signal coverage is poor.
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 replacement handsets were also faulty, with no mobiles to use. The case went to the Ombudsman services to resolve.

Like most of the reviewers on this site, I too have been with O2 for many years and have unfortunately witnessed their gradual decline in quality from their customer services to their strength of mobile signal. 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!!

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.

I recently can home to the uk I had two unlocked iPhones and wanted data more than phone. I went to the kidderminster o2 store and they gave me a fair rate 1 gig for £15 and plenty of calls and texts. We were I going to be in Devon and again I reminded them I needed data coverage. This is where their deceptive practices came to the for. They showed me a 2G coverage map and said you will be fine no problems.
On arriving at our destination in Devon I turn on cell and have little or no phone and absolutely no data. I went into the Barnstable store in Devon and they tell me we only really have 2g coverage in Devon. That brings up the question why are they putting stores and selling phones in an area where there is no coverage?
They suggested I phone customer service on a landline . When I said I don't have one that's why I bought O2 it appeared to be a point of confusion. Maybe all O2 customers should be switching back to landlines because of the poor coverage?
They allowed me to phone customer service I repeated the above story reaffirming it was the data I wanted and need. The representatives answer was she would take the data off and credit my sim for £15 . I explained I would only probably make 20 calls and even fewer texts in the 6 weeks I am in England and I again needed data. Her answer to this was "what do you want to do?" No help ...
This whole experience of the baiting and switching coverage and buyer beware has left a bad taste in my mouth with o2 I would never recommend anyone in the Southwest of England to use their service.
I looked this morning on T mobile and they appear to have much better 3G or 4 G coverage I will be switching at the end of month of having no phone coverage thanks to the crooks at O2

I have been an O2 user since the days when it was called Cellnet when it was owned by BT. It is now owned by telefonica the Spanish telecoms Company.
I am shocked and amazed at all the negativity directed at O2 in the reviews I have read. I work all around the south east and find the signal is generally very good. I also get a phone call every two or three months from customer services to check as to whether I am happy with the service or not. Generally I am very pleased !

I cancelled my O2 mobile contract as from 24 January 2014.
I received a letter saying that I would receive my final account in 4 to 6 weeks. Two days before the six weeks were up (I had expected to receive the final account by post) I received a letter from a debt collector asking for payment of the account together with their fee of 19.16. I paid this as I did not want to be registered as a bad debtor at my time of life (I am 69 years of age and have never been in debt). I contacted O2 to ask for a refund of the 19.16 I had to pay, through no fault of my own, but they refused. I emailed them again but have still not had the courtesy of a reply. I would not recommend O2 for a contract phone to anyone. Like another reviewer, if I could give minus ratings, I would do so.

Increasing prices now and then, customer service advisers speak broken English, probably based somewhere in Asia to cut the costs, don't think about loyalty, all they want is your money . Was offered a free phone with free unlimitied internet for upgrade only to find myself charged 5 extra for "data" when I called the customer service they said it was my fault even though my order on my account says free unlimited internet! Will never use them, at least directly, a lot cheaper through online based companies who offer cheap deals with cashback.

I want to make my experience of o2 customer service very clear to everyone thinking of using o2 services. I took a contract out a few months back and started to experience problems straight away. I had the handset changed in the first 28 days. I have also had a sim swap to try to solve the signal problems causing calls to fail in strong signal areas. After this didn't work I contacted o2 customer service via phone. This is where the service received went down hill very quickly. In the first phone call the member of staff I spoke too agreed there was a problem somewhere. However, they told me there was nothing else they could do to try to rectify this. They also told me that I would not be compensated for the frequent drop out of signal nor would I be able to cancel my contract. I then rang back a few days later due to this problem becoming very frustrating. After over 90 minutes on the phone I was told I needed to do a disconnection and recollection to try to resolve the issue but this would leave me with no service during working hours. (note that 90 minutes on to customer service asking to be put through to management was not an isolated case for me.) When I was finally able to do this I rang back and requested a manager to perform the disconnect and reconnect at a specific time on a specific day. two days after this was meant to occur I rang back to ask why this wasn't done. The manager I spoke too stated he could see the request on the system but couldn't tell me why it wasn't done or contact the manager and ask why. I then had to rearrange a time slot when I could be without signal for the time period needed. the disconnect and reconnect actually happened as requested this time! However, I asked this manager to listen to previous calls and call me back. He stated he would call me back within 24 hours. This was 3 working days ago and I am still waiting. Not only have the managers failed to do as promised they also told me false information on numerous occasions. They where even unaware of any policy regarding reasonable adjustment for a disability! These are only some of the problems I have personally experienced. Also note that the escalation line that you are passed through too when you request to make a complaint is always very busy which to me means my experience of poor customer service isn't an isolated case. I WOULD NOT RECOMMEND THIS COMPANY TO ANYONE!!!!

Don't believe their coverage maps. Bought xperia z on 4g contract and the coverage map said seamless indoor and outdoor 4g in my area. I can't even get a signal outdoors and despite phoning several times, I am still waiting for 02 to get back to me. All they have said so far is that their map may be incorrect and need updating but I have entered into a 2 year contract and spent money on phone accessories on account of there incorrect promise.

Terrible. Terrible network. Used to be good for coverage. These past few months I and my friend who lives in another part of the country kept on having same problems. Calls cutting off very bad reception. Then I find out that other networks like Vodafone. EE which are now orange do 3G coverage in the area I live while O2 far behind in the times don't offer this even though I as well as other customers pay 47 a month for the contract... A service which we are paying for but not recieving!! While other networks provide it. O2 seem proud to be advertising 4G. Before you move on to 4G I suggest you sort out the problems with 3G first. Perhaps o2s problems have come about because they have become too greedy. Too many other mobile providers piggy backing on their network while O2 customers suffer! I visited Shrewsbury the weekend. Big town so shouldn't have any problems here I thought. How wrong was I. I got disconnected from O2 chat (complaining about network coverage!) and my friend who was on phone with his mother got disconnected and attempted the call 3 times until he gave up.... This was in a large town. So what was the excuse here O2??? Stop getting greedy. Sort out your own customers problems because people are getting sick and tired of a bad network that used to be good!

I migrated to O2, after many years with Orange,due to the awful customer service. Initially O2 was excellent, but over the past few years it has become as bad as Orange when I left. The new chat system is not fit for purpose and even though it is secure every time you are passed to another adviser you have to go through the security questions again and provide the history of why you called. Making it a very time consuming process. I recently called them over a query and it took 25 minutes to get through,and after 10 minutes of taking it was cut off. As there was no call back, I tried the Web based chat facility. Another hour and a half later I still hadn't resolved my query. It's as though once they have you the service is no longer provided to the once high standards. Wouldn't recommend unless there are changes.

I have been with O2 for 17 years - prior to this it was BT. I am disgusted with there no customer service since my last 2 year contract. My HTC Desire developed a fault in May - my contact ends in Nov. Basically O2 do not care the phone doesn't work and my contact is over 30.00 a month. I took my phone into an O2 shop yesterday. They called O2 and after 1 hour they offered me 5.00 of the 'buy on' of my contract at 130.00 with only 4 months left on contract and clearly my phone is completely unuseable. I have sent off the phone for repair but had to pay 25.00 deposit to borrow a phone. I've lost all my txt messages and other personal notes as the HTC PC backup is useless. i've lost all my diary entries. O2 basically could not have cared less. I will be going to another network provider in November. Clearly part of the issue is that 'airtime use' and mobile phone are both in the same contract. Even trading standards appreciated my phone was 'not fit for purpose' but O2 didn't apologise or bat an eyelid even when I showed the 'guru' in the the Hempstead Medway the phone. O2 should be ashamed of themselves.

I have been with O2 for years and until recently i would have reccomended them to anyone, I think they must have changed policy or outsourced their customer service people who used to be helpful and polite, now whenever i speak to one they don't seem to actually work for the same company as the last, none can ever tell me the same story and i am still waiting for the phone call from a manager which I have been "assured" is coming from two different reps but never actually does. The only contact i actually recieve are letters threatening to take me to court over a bill i have been trying to pay and resolve for over three months now. Absolutely terrible steer well clear I don't know what changed and it is a big shame as they used to be so good.

I have been with 02 pay as you go for as long as i can remember, the signal quality is really good, download speed is good, internet access is only up to 1 a day, good value for moneyy for 15 a monthg you get unlimited calls and texts to any other 02 number leaving you with your credit to contact any other networks, overal it would take a lot for me to change to a differennt network

Yes, the network and signal are all good and fine, but I am sick and tired of getting O2 spam via text telling me to text STOP to this or a host of other random, smarmy messages about talentless chart musicians clearly aimed at the 13-18 year old demographic. Unnecessary, unhelpful and annoying - I don't want my network operator constantly in my face. Less is more.

I've been with O2 for several years. Joined on a business tariff and payed a little more to get responsive customer service. Until this year any call to them was attended to readily with rarely any wait and always a helpful, transparent and informative support. So good was my service I tended to recommend them. Lately the quality of service has slipped to poor with rude customer service and what seems to be an arrogant disregard to any of my concerns when I called lately about poor reception in many areas when those on other networks keep connection. All I got was a dry 'we have the best coverage' response with no attempt to even acknowledge my concern. I was stupid enough to be seduced into a 24 month contract on the strength of my previous experience and now have over a year before I can cut loose. From good to rubbish in less than a year and I'm not sure they even care that much.

Up until March 2011 i was with 02 but had to leave after a reduction to my tariff was not applied and and i recieved a bill which i should not have recieved. The person who assured me that i would still be paying 20.00 per month neglected to input the renewel onto thier data base and i was subsequently robbed. I tried in vain to reason with them but they did not even give me the benefit of the doubt despite being with them for over four years and having had the same proble 18 months prior to that. 02 have gotten too big so they dont really care if they lose a few thousand people after stinging them for extra undue money. Horrible company to be with.

O2 are great, far better than other networks such as orange and vodafone. I have good reception, not any worse than any other network and at least O2 have uk based call centres which offer good customer service. People seem to moan about the slightest thing, and to be honest the grass isnt always greener on the other side, O2 have their faults but are by no means the worst provider out there and usually the ones that say they will never be back come running back with their tail between their legs. Anyway thats just my opinion, everyone has different views but i think O2 are cool :-)

I have had no problems with 02. l have always had signal even when my friends who are on other networks don't. Customer service at any company nowadays is poor but I haven't had any problems with 02. Have been with them for years and will stay with them. They have a wide range of different tariffs and the one I have picked is cheap but still gives me everything I need. Moved to Orange briefly a few months back and had a terrible time with them not to mention they were extortionate !! There customer service appalled me but this just confirmed how good 02 were and I quickly moved back!

A few years ago, i'd have rated O2 a well deserved 5 - not now though, 1's as good as they get. Poor customer service, expensive tarrifs, awful reception...they've gone from alpha male to runt of the litter. If less is more then O2's stance must be less for more. I pay through the nose for a contract which O2 feel they can change on a whim. 6 weeks left on a 24mth contract...then i'm out for good!

I have been a customer of O2 for 8 years and I have been receiving appalling service over the last few months and especially the last few days. I am not one of theses people that only complain when things go bad as I have on numerous post supported O2 completely. Their service is now at a point where i'm really struggling to see the point in staying with them. Their price plans and tarrifs are now one of the most expensive! Not to mention that they have done away with free unlimited internet for your mobile devices! I hope more people complain to make them realise that they are now losing valuable ground. Any other network should capitalise on their 18 million customer database! soon to be 17 999 999.

On the whole their customer service is pretty good. The fact that their call centres are UK based is a big plus. My brother is with T Mobile and he says that althought their customer service reps are pleasant, he can barely understand a word they say and they can rarely understand what he's asking them. However their signal strength is pretty bad. When at my friends I have to lean out of the window or go to the top of her garden to make a call. Even at my own home I regularly loose connection during calls. Another friend who is on O2 also has the same problem. I am currently with them for Broadband and home phone otherwise I think I may have moved to Vodaphone simply because of the useless signal strength I get

I'm in two minds about O2 - when I first signed up to a contract with them in 2006 they were excellent - would recommend the best phones, get you the best deals and I never had a problem. However since 2008 they seemed to be getting in poor quality phones - maybe I just had bad luck but my last three phones have been terrible and I had so much trouble returning them. When upgrading contracts the staff are now unhelpful to the point of rude and when I upgraded last year I was told I was on an eighteen month contract but when I checked my bill they'd put me on a two year contract with a phone that didn't make phone calls!! However there are good points to 02 - the freebies for 02 priority are pretty good, no other phone company offers the range of discounts and freebies O2 do (although these could be better) Also you can now talk to a customer service advisor online and these seem to be a lot more efficient and helpful than when you phone up.

I think O2 are possibly the worst service company I have ever had the misfortune of dealing with. After the crazy bills of 700 quid for a month I recieved when I occasionally was abroad with work I decided to leave and join vodafone, who have a far better passport package. But to add insult to injury o2 have continued to charge me for an inactive usb broadband dongle which is out of contract and I don't even have any more. I tried to call them to cancel several times but their highly ineffective staff could never locate my account, which rolled on and on. Having cancelled the direct debit they have now passed me over to a debt collecting agency for a service I have not been using but due to their inefficiency have been unable to cancel. So the robbing continues. Customer service is terrible.

o2 isn't as astonishing as it's reputation was portrayed in the past. I believe it has made new terms and conditions to create a profit rather than impress their customers such as; the o2 unlimited tariff - when your month for unlimited has finished, your charged 15p per minute for the first 3mins you call someone. This means, EVERYTIME you ring someone in the first 3mins you'll lose 50p. Also, I wouldn't reccomend this network for smartphones, you can find better deals like internet and texts from T-Mobile. However, the 'o2 surprises' and connection is excellent. On the otherhand, i've noticed calls from Sony Ericsson mobiles on o2 sometimes is affected by a disturbing buzzing sound. Overall, o2 is acceptable, but i wouldn't reccomend it.

I have tried a couple of P&G sims from other suppliers but not so good coverage where I lived ( Hertfordshire ). If there is a good signal in your area they are the best.

O2 is a good network for any payg user using a standard mobile phone. Anyone who signed up to a simplicity payg package before april 2011 have had a really good value package. However, O2 (with exception to O2 linked companies like giffgaff and tesco mobile) has a larger price tag now and the signal range is poor, especially for smart phone users. Even though there is a large area of signal in the UK, it doesn't cover all areas (mainly costal and countryside areas) and there is little 3G signal which is bad for some smartphones owners. Customer Service are helpful but the line to the service is very poor quality when I've phoned them. I would recommend staying with this network for any user without a smartphone and current simplicitly payg users (from before april) but if you have a smartphone and are looking for a different network, I would not recommend O2.

This may not be relevant as I've only had an 02 sim in Slovakia where the choices are 02, or Orange. As I've said in another review on Orange, I would never give my custom to Orange ever again! So 02 it was for me. Coverage in Europe seemed pretty good on the whole (although it was better with my Vodafone sim). Calls were expensive, both locally and internationally, but that may just be Slovakian tariffs, not 02 in particular.
