Choosing your SIM Only tariff

O2 is the UK’s leading network in the UK and their popularity is well deserved. O2 offers a wide range of plans specifically designed to suit the needs of smartphone users.

You can also choose from a variety of data packages to suit your needs including 1-month, 12-month and 18-month contracts.

O2 has a great customer service centre and you can get easy access to your bills online. Check O2’s coverage in your area here.

What about Internet?

The majority of O2 customers choose at least 2GB of data, which is sufficient for average use. Once you've reached your data allowance and exceed it, your connection will either be throttled or stopped. This can be annoying to say the least but could also be a good thing so you don't get charged excessively. You can purchase an additional data Bolt-on should you require normal service until your next billing period.

Are you a high data user? Your best option is O2’s premium 4G tariff. This provides Unlimited data for just £33 p/mth. Other deals include 100GB for £18 on an 18-month contracts SIM.

SIM Only Contract’s top tip:

The cheapest O2 SIM Only is £10 p/mth on a 12-month contract. This includes 5GB of data and Unlimited minutes of talktime. It isn't as cheap as other networks but still offers reasonable value. If you are looking for more data then we recommend a tariff in the £15 to £20 range.

Our editor says:

There are awesome offers available including FREE Disney+ and other value added benefits but in terms of minutes and data O2 don't really impress that much.

The Good

I like: Roam at no extra cost in 75 destinations.

The Bad

I don’t like: The data allowances with O2 are very much on the low side and don't match up with the high usage of many smartphone users today. There are cheaper options available with more inclusive data. Take a look at deals from Three, Virgin, Vodafone, BT and Plusnet.
