Pay & Go™

Upgrade with us and we’ll reward your loyalty by giving you 10% of the value of your top-ups as call time worth up to £200 or 5% as discount off a new handset up to £100.  Based on top ups over the last 18 months or since connection or your last upgrade whichever is the most recent.  It’s up to you how you take it!  So, the more you top-up, the more you receive!

*The 5% handset discount is not available if upgrading to iPhone on Pay & Go. Terms apply

You can choose from a great selection of Pay & Go mobiles and you can upgrade in one of two ways:

• Upgrade over the phone by calling 2550 from your mobile
• Upgrade in one of our O2 shops

If you've already purchased a new handset with a new SIM card, simply follow the steps below to register your upgrade and claim your reward.

If you have just purchased a 3G handset you need to ensure that you have a 3G SIM Card. If your old SIM is not 3G you need to contact customer service on 4445 to arrange a number migration if you wish to keep your old number.

• Call 2210 from your EXISTING handset, using the EXISTING SIM card -  to find out how much reward you are eligible for.
• Follow the prompts
• You’ll get an authorisation code – make sure you note it down, as you’ll need it later.

• Call 2210 from your NEW mobile, using the NEW SIM card
• Enter your authorisation code and record your name and address when prompted
• Once you’ve accepted and confirmed your upgrade request you’ll be given a confirmation code for your records
• Now insert your EXISTING SIM card into the new mobile.
• Your free calltime credit will be automatically added to your new mobile after 14 days, and confirmed by text message.
