Contact the O2 Customer Service Team 

Managing your O2 phone service, and using O2 discount codes, is quick and simple from your personal online account, but there are sure to be times you need to get in touch with the O2 customer service team. You may need to find out more about O2 WiFi calling, or perhaps you need to call O2 to cancel your contract. No matter the reason, you can get in touch with a representative by using the O2 phone number, 202, from your mobile device. All other phone numbers are listed on the O2 website; alternatively you can chat with an O2 expert online using the LiveChat facility as well.
