FAQs
What is a Pay Monthly SIM?
A Pay Monthly SIM Only deal gives you a SIM card with a fixed monthly allowance of minutes, texts, and data, without a new phone. It’s perfect if you already have a device and just need a SIM plan to stay connected.
What are the benefits of a Pay Monthly SIM deal?
With an O2 SIM Only deal, enjoy a flexible plan with generous data, texts and minutes, predictable billing, and access to our reliable 4G and 5G network.
Plus, get exclusive perks with O2 Priority and earn extras with O2 Rewards.
Can I keep my number when switching to an O2 SIM Only plan?
Yes, keeping your current phone number is easy. Just request a PAC code from your existing provider, give it to us, and we’ll transfer your number to your new O2 SIM Only contract.
What types of SIM Only deals are available?
At O2, we have a range of SIM Only plans to suit every need. You can even adjust your contract length and tailor your airtime to suit you.
Want more airtime? We've got you covered. Our Plus Plan and Ultimate plans allow you to level up your Airtime Plan with a heap of extras. You can even benefit from O2 Switch Up and swap your phone for a new one every 90 days. And, get an extended 3-year warranty and roam freely up to 25GB while travelling abroad.
How much data do I need?
At O2, we understand that everyone has different data needs. That's why our plans are customisable.
The amount of data you need is entirely up to your usage habits. If you regularly connect to WiFi or hotspots, you might not need as much data. But on the flip side, if you live somewhere with a poor WiFi connection or are regularly on the go, opting for more data might be the best decision.
Can I get an unlimited data SIM?
Yes, you can. Stream, download and scroll without restrictions with one of our unlimited data SIMs.
Do O2 Pay Monthly SIMs including EU roaming?
Yes, they do. You can roam freely in the EU, up to 25GB.
With a Plus Plan or Ultimate Plan, you can utilise your airtime across even more destinations including the USA, Mexico, Canada, New Zealand, Argentina and Australia. Learn more about EU Roaming.
Can I get a 5G Pay Monthly SIM?
Yes, you can. As long as your phone is 5G compatible, you can enjoy super-fast 5G speeds with a Pay Monthly SIM from O2.
Is there a minimum contract length for Pay Monthly SIM plans?
The minimum contract length is 30 days. You can also choose a 12-month, or 24-month contract, whatever works for you.
What SIM type do I need?
There are four types of SIMs available: standard, micro, nano and eSIM. An eSIM lets you manage your Airtime Plan without the use of a physical SIM.
If you're unsure what size you need, it's best to check the instructions that came with your device.
