A SIM card is a chip inside your phone that stores information and connects you to a wireless network. This lets you easily switch carriers by changing 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.

All US Mobile’s  SIM cards are pre-cut so that you can choose the size you need. It’s formatted as the image above, enabling all three sizes. You simply press gently along the perforated line of the chosen size and voila – your SIM card is cut in the correct size!

Inserting a SIM Card

To put a new SIM card into a phone, or a connected device, you'll usually need a tool to open the SIM slot. The slot is usually located on the side of your phone. Next, to the slot there's a small pin hole. You'll have to use a SIM ejector tool or a small pin to push the slot out. 

Insert a SIM Card

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 device you have.
