Why choose O2?
O2 has a great choice of phone and data plans to choose from. The current offer allows you to order a free O2 SIM card that is delivered direct to your door. Check out the options below to see which option would work out best for you.
O2 Phone plans
SIM Only Deals
These plans give you plenty of minutes, texts and data. Each month you can choose a fixed monthly amount and for this O2 will give you an allocation of minutes, texts and data.
Plans start from just a 30 day contract. Commit to a 12 or 24 month plan and you can enjoy cheaper monthly costs and in many cases extra data.
PAYG plans
Under 18 or don’t want to sign up for a monthly plan? No problem as Pay As You Go is still alive and well in 2026 with O2! Top up and simply just pay for what you use and not for what you don’t.
O2 Data Plans
These are great because it means you can use your iPad or tablet without the need for an open Wi-Fi connection. All you need to do is make sure your tablet has a SIM Card slot.
Every time you top-up you are given an allowance of data which is measured in MB. Once used, you can add more credit for when you need it next. The great thing about these plans is that they are Pay As You Go based so don’t have a contract making them really flexible.
Roam freely
O2 was the only UK mobile phone network to not bring in EU roaming charges after Brexit was approved. Each month you can use up to 25GB of your plan data when in the EU.
Great UK coverage
O2 has spent many years not to mention lots of money investing in its network. The end result means you can use your phone and devices in more places and enjoy great speeds when surfing the internet and sending emails.
