Grab yourself a new SIM card with the data, texts and minutes you need. Whether you’ve already got a SIM-free mobile phone, or just fancy switching to a new plan, we have three types of SIM card for you to choose from. Basic pay-as-you-go SIMs, flexible SIMs that let you change package every month, and long-term SIM-only-contracts.

SIM CARDS - IN A NUTSHELL

SIM card sizes

SIM cards come in 3 sizes; Standard, Micro and Nano.

What size do you need?

Your phone user manual will tell you. Most new smartphones including iPhone and Samsung handsets need a Nano SIM. Some new handsets use the Micro SIM. An older handset (pre 2010) may feature a Standard SIM.

Combi SIM cards

Most networks now provide combi sim cards, which come with all three sizes of SIM card - just pop out the size you need to fit your phone.

PAY-AS-YOU-GO explained

WHAT IS PAY-AS-YOU-GO?

Pay-as-you-go SIMS have no commitment and no contract. Top-up your data, text or minutes by top-up card, credit or debit card whenever you want and choose the amount that matches your budget.

WHO'S IT FOR? - BUDGET CONSCIOUS, OCCASIONAL USERS

Pay as you go is great if you don’t use your phone that often or want to know exactly what your spending. There’s no credit checks either so it’s great if you’re young or don’t have a perfect credit history.

flexible sims explained

WHAT IS A FLEXIBLE SIM?

A flexible option, with no commitment, no contract and no credit check. Register a credit or debit card, choose the amount of data, text and minutes you need each month, without being tied to a long-term contract. Then, if something comes up, simply change your deal the next month to suit your new usage.

WHO'S IT FOR? - NO COMMITMENT, VALUE SEEKERS

Flexible SIMs are great if you want better value than PAYG but don’t want the commitment of a 12 month contract. They don’t need a credit check either (just a credit or debit card) so you don’t need a strong credit history to get one. Also, as the name suggest, it’s really easy to change tariffs each month so if you can’t make up your mind as to what package you want, these SIMs will be a great place to start.

sim-only contracts explained

WHAT IS A SIM-ONLY CONTRACT?

Generally, 12 month contracts, with data, texts and minutes that refresh every month. Find the deal that meets your budget and usage needs, which will probably depend on how many calls you make and how much data you use. To get a SIM-only contract you need to pass a credit check and then set up a monthly direct debit.

WHO'S IT FOR? - Data Hungry, Ultimate value hunters

SIM Only contracts are great if you want the best deals on lots of data and are happy to commit to a 12-month contract. Remember – as it’s a longer contract, you will usually need to pass a credit check. Combining them with a SIM Free phone is also a great way to save money as they usually work out cheaper than taking a contract with a handset contract over 24 months.
