Which SIM card do I need?

A SIM card is the small microchip that sits in your mobile phone and is the thing that makes your phone connect to a network so you can make calls, texts and go online. The type of SIM card you need depends on the phone you'll be putting the SIM card into. If you've already got a SIM card in your phone then you can remove it and check the size with the measurements below.

OK, we said 3 types, but there is a magic fourth type of SIM card and it is called a Combi SIM, short for combindation. This is effectively a Standard SIM card with a Micro SIM card inside it, which can be popped out to work on handsets that need Micro SIMs. They networks produce these as they cover more handsets and cheaper to manufacturer. Some networks also call this a multi-fit SIM. This SIM card size will fit phones that require either Micro or Standard SIM cards.
