More about O2

O2 Financing 

O2 knows the tech can get expensive. That’s why the company offers easy financing so you can get the highest tech at the lowest monthly cost.  Want the latest phone but not eligible for an O2 upgrade? Use O2 financing for affordable payments that won't break the bank. Pay a small portion up front, and spread the cost over 12, 24, and 36-month terms with 0% APR.

You can get a new phone, Apple Watch, video game consoles, tablets, or more! Sometimes you can find bonus offers like free Disney Plus subscriptions. At times, there might be an O2 coupon code to save on upfront fees. 

O2 Multisave Deals

One of the easiest ways to get a discount at O2 is to take advantage of the Multisave promo. Add a new line to your account and you'll enjoy a 20% discount on your Airtime plan. You can up to 20 lines to your account with 5 Refresh contracts included. 

To take advantage of this O2 promotion, choose a phone, tablet, or SIM on an eligible tariff direct from O2. Use your new device to send a text message to O2 at 21500 with the word "LOYALTY." Within 3 business days, you'll see your O2 discount of 20% applied to your account. Once complete, you'll be able to manage all your existing lines on one monthly bill. 

Look out for any O2 promo code or O2 voucher code that could help you save more when purchasing a new phone or SIM.

O2 Top Up

If you run out of data or credit, don’t worry! Adding an O2 top up to your account is easy! Sign in online to top up your account on the O2 website. Or, call 4444 from your device to top up over the phone. You can also set up an auto top-up every month so you never forget. 

O2 customers benefit from 10% of their top-ups back in bill credit every 3 months. 

Unlock Your O2 Phone

While most newer O2 phones come unlocked with their plans, some older devices may still be locked to the O2 network. If your device is locked, you can ask O2 to unlock it for you at any time, free of charge.  Choose the Pay Monthly, Pay As You Go customers’, or O2 Business customers’ section on the O2 help page to find out more details.
