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.
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.VIEW PAY-AS-YOU-GO SIM CARDS
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.
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.VIEW FLEXIBLE SIM CARDS
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.
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.VIEW SIM ONLY CONTRACTS
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.
