Pay & Go sims

Free sims for phones and tablets

Get a Pay & Go sim

Our pay as you go tariffs are flexible. You also get lots of perks, just for being on O2. And you can keep your number, if you've joined from another network.

If you're already on O2 Pay & Go, you don't need to order a new sim. Sign in to My O2 or call 2202 to switch to a new tariff - you can do this once a month if you want to.

Now you can get 50% extra data with Pay & Go Big Bundles. Simply choose your tariff below. If you’re already with O2, text BIG50 to 2424 to opt in. Offer ends 30 March.

Top up the right amount for your chosen bundle each month and we'll exchange your credit for your minutes, texts and data allowance. And until 30 March, you get 50% extra data with all our Big Bundles.

There's no contract with Big Bundles, they last for a month and renew automatically on the same day each month, but only if you've got enough credit to cover the payment. If you don't, you'll be charged at our standard rates, until all your credit's gone.

You'll get your bundle allowance back when you top up enough credit again.

Top up as often as you want and keep your credit to use how, and when, you like. Top up regularly and we'll give you a free UK allowance of O2 to O2 minutes and texts, as well as a bit of data.

Once your free allowance is gone, you'll use your credit for all calls, texts and data, at our standard rates.
