How to Insert a SIM Card into a Mobile Phone

By now, most of you know what a SIM card is. If you need a refresher though, a SIM is a memory chip inside your phone that stores information and connects you to a wireless network. You also know that it makes it easy to switch carrier by moving your SIM. But do you know how to insert your SIM card in a new phone?

SIM Cards come in Three Sizes

Depending on what kind of phone you have, you might need a different sized SIM card:

  • Mini SIM: The Mini, also called Standard SIM, is 15 x 25mm. You would use the Mini SIM in 2011 phones and older, like the iPhone 3.
  • Micro SIM: A Micro SIM is 12 x 15mm, and is commonly used by phones manufactured between 2012-2013, like the iPhone4.
  • Nano SIM: The smallest SIM is called Nano and is just 8.8 x 12.3mm. If you have a newer generation phone, like iPhone 5 and above, you would use the nano-sized SIM.

Inserting a SIM Card

In order to insert a new SIM card into a phone, or a connected device, you need a tool that will open the SIM slot. The slot is usually located on the side of your phone. You’ll see a very small hole, which you’ll have to press to open the slot. You won’t be able to do with your thumb, you’ll need some kind of tool. Most phones come with this tool, looking something similar to this one in the image.

In case you don’t have that tool, you can always use a paperclip which you’ll unfold and use for the same purpose. Press lightly and the slot should pop out enabling you to insert the SIM card. The video below is an example of how you would insert it into a Xiaomi Mi Mix but the principle is the same, no matter what phone or other connected devices, you have.
