FAQs

How do Big Bundles work? Collapsed link

Just top-up the right amount each month for your chosen Big Bundle and we'll exchange the right amount of credit for your minutes, texts and data allowance.​ You'll be able to rollover your data at the end of the month.

Big Bundles last for a month and renew automatically on the same day each month, if you've got enough credit. If you don't, you'll be charged at our Big Bundles standard rates until all your credit's gone. You'll get your bundle allowance back when you top up enough credit again. Big Bundles terms apply.

How do I claim £10 free credit? Collapsed link

You can claim £10 free credit when you buy any O2 Big Bundle. To claim your credit, text FREE10 to 21500 within 28 days of ordering your sim.

What happens if I don’t use my phone for long periods? Collapsed link

Can I keep my number? Collapsed link

Yes. If you’re moving from another network, before you can transfer, we’ll need your PAC. Once you’ve ordered and received your temporary O2 number, fill in the keep my number form. Find out more about keeping your number.

If you’re moving from O2 Pay Monthly to O2 Pay As You Go, get in touch with our Pay Monthly customer service team. We'll do the rest. If you're on O2 Refresh you can only move to Pay As You Go once your Device Plan is paid. If you're not on O2 Refresh but still in your contract minimum term, you may need to pay a termination charge.

I ordered a sim but it hasn't arrived, what can I do? Collapsed link

What happens if I use my Big Bundle up early? Collapsed link

You’ll get a text when you're close to using all your data. If you run out of data, you can either add a Bolt On for more data or wait until your O2 Big Bundle renews the following month. You’ll need to ensure you’ve got enough credit to cover the cost of your O2 Big Bundle on your renewal date.
