SIM card sizes

There are three different SIM card sizes in the various Apple iPhone models. Each has an adapter in case you want to switch to a phone with an incompatible SIM Card slot.

  1. Standard SIM Card - The original SIM Card size is similar to any card in your wallet. However, if you want to transfer your data to a new phone, you can take out a small portion of the SIM card to insert into another iPhone. The original iPhone along with the older iPhone 3G and 3GS all use the original SIM Card, according to Apple.
  2. Micro SIM Card - Micro SIM Cards were introduced with the iPhone 4 in 2010. The Micro SIM is also used in the iPhone 4s. The Micro SIM Card size is small compared to the original SIM card but not quite as small as the Nano SIM card.
  3. Nano SIM Card - Nano SIM Cards are the smallest SIM cards that came out in the iPhone 5 in 2013. The cards have been in every iPhone since, all the way up to the iPhone 7 Plus.
