O2 contact number for any customers on Pay Monthly contracts – 0344 809 0202

If you have questions about your Pay Monthly account then you can ring O2 on 0344 809 0202.  The Pay Monthly scheme means you pay a fixed tariff amount every month that includes data, minutes and text allowance to use within that set period.  If you are running out of these credits and need more, you can ring this number to talk to someone about what your options are.  The contracts also come with a selection of phones to choose from, some with an upfront fee and all with a monthly cost.  If you are ringing from an existing O2 phone, you can just dial 202 to reach this team.

If your contract is due to expire, you will be eligible for a new phone although with O2 Refresh.  This lets you renew your contract early and get the choice of a new device.  You can use the website section to find out more and selection a phone – – or you can call customer services or even visit one of the stores.  You can use to find your nearest store by town name or postcode.

When you are on O2 Refresh, your bill comes in two parts – one for the phone and the other for the airtime plan.

When you trade in your device, you have to clear the remaining amount of the phone balance.  Once this is cleared, you can pick the new phone that you want.  You can also use O2’s recycling scheme to get some money for your old phone.

To see what your phone is worth to recycle, go to and put in the details.  You can even choose the sell option if you are ready to go ahead with the sale immediately.  You then send the phone to the address provided and the money will be sent to you.  There is a fast payment option that would see money put into your account on the same day.  Recycling can earn you cash and also help the environment by correctly disposing of the old phone – it even helps the company improve lives of young kids around the UK through their different schemes.

Customer services team – 0344 809 0222

If you need to call the ‘pay as you go’ team, you can do so on 0344 809 0222 or by calling 2202 from an O2 mobile.  The difference between Pay Monthly (known as contract customers by some) and pay as you go is that the latter doesn’t involve a monthly bill.  Instead, you top up with credits as you need them.  It does mean that you don’t get any free minutes, texts or data and have to pay for everything.

To call the number, you do need to have enough credits to do so.  You will also get messages to remind you when you are low on credit and then you can opt to go and top up straight away.  You can also use different ways to check how many credits you have left:

  •         Call 2202 from your mobile
  •         Hit *#10# then the call button for an automated figure
  •         Press ‘2’ on your keypad for the hotkey credit checking service

You can use your Pay as You Go account in over 200 countries around the world and can access over 400 networks.  O2 Travel means you can also use the internet at a lower rate than normal when you are in Europe.

Voicemail is also available when you are abroad but listening to messages is like calling the UK so you would see a charge of the same rate.  You don’t receive a charge for receiving the voicemails so if you don’t need to listen to them urgently, you can wait until you come home.  Always know your PIN for the voicemail service, otherwise, you won’t be able to access the messages.

Call 901 from your device to access the voicemail and you will be sent straight to the inbox or be required to enter your PIN number.  When you first get the phone or do a reset, you will need to set a PIN and you can change this PIN at any time by dialling 901 then pressing * and option 4.

If you have trouble resetting your PIN via this method, you can text the word RESET to 802901 and a temporary PIN will be issued to you.  

Once you use this to access the account, make sure you change it to something difficult for anyone to guess but easy for you to remember.  You can also disable voicemail by dialling 1760 from your phone.

It is best to keep your network to manual rather than automatic on pay as you go then the phone doesn’t automatically connect to a network as you move around and incur roaming fees.  On manual, if there is no O2 signal, it won’t just connect to another network.
