Why choose O2 SIM only deals?

If you’re looking for a new SIM card, it’s important that you make an informed decision and find a deal that works best for you.

Here are some reasons you might want to consider O2 for your next SIM only deal:

  • Network coverage: O2 customers enjoy 4G network coverage across 99% of the UK.
  • Roaming: O2 customers can use their minutes and up to 25GB of data as normal across more than 40 European destinations. And O2’s Travel bolt-ons means you can use your minutes and data in 27 destinations outside of Europe. These may be included in your contract or available to buy as a roaming add-on.
  • Customer service: According to Ofcom’s latest stats, 85% of O2 customers are satisfied with their service overall. Although the number is high, it’s two percentage points less than the industry average.
  • Data: O2 SIM only deals include generous 5G-ready data packages. Customers can choose from 12GB, 100GB, 150GB and unlimited data options.
  • O2 Wi-Fi extra: All O2 customers can automatically connect to one of O2’s 15,000+ Wi-Fi hotspots where the signal is stronger than 3G or 4G in that area.
  • Perks: O2 customers can choose from 3 or 6 months of free Disney+, Amazon Prime, Audible or other services. If you’re a Virgin Media broadband customer, you might be eligible to double the data on your SIM, plus get a broadband speed boost.

O2 Rewards and O2 Priority benefits

O2 Priority is a big draw for many of its customers. Here’s what it gets you:

  • Ticket access: O2 Priority gives customers access to exclusive gigs and events and 48 hours early access to ticket sales for some widely available events.
  • Venue perks: Enjoy priority queues and the choice to bring three friends with you, even if they’re not on O2. Free cloakroom use, free power banks and VIP bars may also be available, exclusively for O2 customers.
  • Other O2 Priority rewards: O2 customers also enjoy discount cinema tickets, offers from high street favourites, bars and restaurants, and the chance to win trips and experiences.

Choosing an O2 SIM contract

Here are 5 things to think about when buying a SIM only deal from O2:

  1. Contract or PAYG: O2 offers SIM only deals on a contract as part of Pay As You Go bundles. You should decide which works best for you before making your choice.
  2. Contract length: If you’re happy to sign up to a contract, it’s important to think about how long you want to be tied to a specific deal. You might be able to afford monthly payments today but will you be able to afford them in a few months’ time?
  3. Data needed: Working out how much data you need can be tricky. A data calculator could be helpful when choosing the right package for your needs.
  4. Data-only SIM: Once you’ve decided you want a SIM only deal, it’s time to think if you want a data-only SIM. If you’re buying a SIM for a tablet, minutes and messages won’t be necessary, just data.
  5. Your device: The major drawback of any SIM only deal is finding a device separately. It’s important to make sure that the cost of the device balances with any payments for your SIM. Some people decide to keep their existing handset and others choose a refurbished phone.
