About O2
O2 is a UK mobile network that sells pay monthly and pay as you go SIMs, SIM-only plans and mobile broadband alongside handsets. Its online shop stocks phones from Apple, Samsung, Google Pixel and other Android makers, as well as tablets, laptops, smartwatches and accessories, with trade-in offers on older devices.
O2 - frequently asked questions
Here we answer the questions people ask most often about O2 - from voucher codes to credit checks and customer rewards.
How do I use an O2 voucher code?
Choose your phone, plan or accessory in the O2 online shop and continue to the checkout. Enter the voucher code in the promotional code field before confirming the order, then check the updated total.
Does an O2 contract involve a credit check?
Yes. Pay monthly contracts are a form of credit, so O2 runs a credit check before approving one. O2 is operated by Telefonica UK Limited, which is authorised by the FCA for credit.
What is O2 Priority?
Priority is the O2 rewards programme for its customers. It gives access to tickets for events and a range of offers, and sits alongside other schemes such as O2 Extras and rewards for pay as you go users.
Tips for using a O2 voucher code
Enter your O2 voucher code at the checkout before you confirm your order, and check the summary to see whether the discount applies to the device, the monthly plan or both. Read the terms first, as a code may cover only certain handsets, accessories or new contracts, and it usually cannot be added once an order has gone through.
How to save at O2
An O2 voucher code is a simple way to take something off an order. Beyond that, trading in an older phone can bring down the cost of a new one, and the deals page gathers current offers on phones, tablets, watches and SIM-only plans. A SIM-only plan avoids paying for a handset you do not need, while Airtime Rewards and O2 Extras are worth checking once you are a customer.
Delivery
Standard home delivery is free on devices, SIMs and accessories. Order before midnight, Sunday to Thursday, and it should arrive the next working day, although remote postcodes can take up to 48 hours. Paid premium delivery offers timed slots, and click and collect lets you pick up the same day in store when the item is in stock, with orders held for 7 days.

Customers can join the Priority rewards programme for event tickets and offers, collect Airtime Rewards and use O2 Extras, and the trade-in scheme gives value back on an older device when upgrading.
