Railcard and Airtime Plan offer details
As a student you'll get a free 16-25 Railcard, and 20% off your Airtime Plan, when you sign up to O2 Refresh.
The Airtime Plan covers your calls, texts and data. The offer doesn't apply to your Device Plan, which is the monthly cost of your device.
You'll need to claim your Airtime Plan discount within 28 days of signing up to O2 Refresh. You'll get your Railcard discount code through Priority, 2-4 weeks later.
