Contact O2: Phone Numbers & Support

O2, part of Virgin Media O2, is one of the largest mobile network operators in the United Kingdom. With millions of customers across Pay Monthly, Pay As You Go, and Business accounts, O2 provides multiple ways to get in touch with customer support.

Calling O2 from Your Mobile

The easiest way to contact O2 is by dialling 202 from your O2 mobile phone. This call is free and connects you directly to O2 customer service. The automated system will ask you to select from options including billing, technical support, upgrades, and general enquiries. Have your O2 account details ready to speed up the process.

Calling O2 from a Landline

If you're calling from a landline or non-O2 phone, dial 0344 809 0202. This number is charged at your standard landline rate and included in most calling packages. This is the best number to use if your O2 phone is lost, stolen, or not working.

Pay As You Go Support

O2 Pay As You Go customers have a dedicated free helpline: 0800 032 1402. This number is free from any phone, including non-O2 mobiles and landlines. PAYG customers can also text BALANCE to 20202 to check their credit balance.

O2 Business Support

Business customers should call the dedicated O2 Business line on 0800 977 7337. This connects you to specialist advisors trained to handle business account queries, fleet management, and enterprise solutions.

Tips for Faster Service

• Call during off-peak hours (early morning or late evening) for shorter wait times
• Have your O2 phone number and account details ready
• Use the My O2 app for quick queries like checking your balance or paying bills
• Try Live Chat for non-urgent matters - often quicker than calling

Lost or Stolen Phone

If your O2 phone is lost or stolen, contact O2 immediately on 0344 809 0202 (available 24/7). They will block your SIM to prevent unauthorised use and can blacklist your device's IMEI number to stop it being used on any UK network.
