I've been with 02 for many years - we've got three phones in the family and always raved about them; great service, great signal etc etc. However after speaking to a Customer Service Advisor today I am taking my hard earned, tax paid money to another company. He was rude, arrogant and totally unhelpful - he is so in the wrong job. That seems to be a problem with 02, in the main the staff are great but it is always that one in ten exception who are just useless, and to make matters worse they are so arrogant they cannot see how pathetic they are! I wish I could give them zero stars but one is the minimum.An ex 02 customer of many years standing

My parents' landline, which is with O2, has been faulty all day. They are in their seventies and cannot use the computer. They have mobiles with which they contacted me to ask if I could phone O2 and ask to have the line checked/repaired. Both have cancer and one has brain tumours whilst the other has heart problems in addition. The telephone is essential to them. I contacted the O2 online 'Guru' (called Dale but I think he called it Dail!). He absolutely refused to check the line until he spoke to the line owner and gave me a free number to call! How is this possible if the phone is not working? He asked for the letters of the security code!I don't have to be ...  Read the complete review

I have been with o2 for donkey's years. I think this is my 8th year with them. It's also my last. Since the beginning of 2012 I have been finding they are getting worse and worse service wise. I recently moved, and I get very ppor signal. My friends on other networks are fine. My friends on o2 are not. I go to uni in a large city in the midlands. My friends on o2 get no signal. My friends on other networks do....Do you see the pattern here?! it's madness as o2, imo, used to have the best coverage of all. I had a brief flirtation with vodafone and one with orange too, but neither lasted long as I was a die hard o2 fan and they just didn't measure up. Sadly, this is no ...  Read the complete review

I have been with O2 for as long as I can remember having a phone! I have worked with both pay-as-you-go O2, and more recently, a 24-month contract that I have started. The reason for staying with O2 for so long? They are a genuinely all-round great phone provider. O2 have an amazing support team set up both in store, online and on the phone. In terms of pay-as-you-go, O2 have some brilliant offers that could appeal to almost anyone. There are offers that can be paid for such as bolt-ons that provide extras for your phone such as more texts, calls or internet usage. There are also offers that can be attained without payment, these have been seen on the t.v. and are ...  Read the complete review

Never yet had any problems with o2, always a strong signal wherever I go and fast internet speeds. A few years ago when I upgraded to a 3G phone and put my old sim card in from 2003 I found that I needed a 3G sim card to access all the phones features. After emailing o2 they sent me one the next day and after one more email sent that day with some info they needed it was up and running. Very good customer service. I see no reason to ever change networks.
