FAQs

What is a Pay As You Go SIM? Collapsed link

A Pay As You Go SIM is the perfect way to get a SIM without being tied down to a contract. Instead of paying a fixed monthly fee, you top up your SIM card with credit, which you can then use for calls, texts, and data.  You have the flexibility to only pay for what you use, without any long-term commitment.

What types of PAYG SIM only contracts do O2 offer? Collapsed link

There are two types of O2 contract-free SIM only offers: Big Bundles and Rolling Plans.

Big Bundle
Our Big Bundle sim only deals mean you can choose your monthly data allowance. You top up your sim card, and we exchange your credit for your monthly calls, texts and minutes allowance.


Rolling Plan
Rolling plans are contract-free SIM only packages – that don’t require top ups. They include an allowance for minutes, texts, and data. Extra options include minutes for international calls from the UK to 42 countries. 
With a Rolling plan, you set up paying for your monthly allowance using your debit or credit card. Your monthly payment will be taken automatically, and your allowance will refresh. You can carry over up to 100% unused allowance, so you never lose out. You're in control and are free to change or stop your Rolling plan at any time. Read more about our Rolling Plans.
