There are loads of different smartphones, tablets and dongles on the market, each with different features, specs and USPs. They all require a SIM card, but while all SIM cards work in the same way and do the same job, they nevertheless come in different sizes.
Here’s our guide to the different types of SIM available.
This is the ‘normal’ sized SIM, the size you’re probably used to seeing over the years. These SIMs are mainly used in older phones and devices. That means devices like iPhone 3GS and Samsung Galaxy S II.
As the name suggests, these SIM cards are a smaller version of standard SIM cards. It’s about half the size of a standard SIM and while it was first used with iPhone 4, most modern smartphones now predominantly use a micro SIM.
This is the smallest SIM of the three – it’s around 40% smaller than a micro-SIM. Apple has made the nano SIM the standard SIM for all their devices, such as iPhone 5, 5s, 5c, 6 and iPad Mini.
While the newest Apple devices all require a nano SIM, they’re not on their own. Nokia have recently followed suit with phones such as the Nokia Lumia 1520; while HTC have also started to utilise the nano SIM with the HTC One M8, and more manufacturers are likely to follow suit.
Why have SIMs changed in size?
It mainly boils down to advances in technology and improved usability. A smaller SIM means you can have a thinner, lighter phone.
