All US Mobile SIM cards are 3-in-1, which means that every SIM Card can be broken into three different sizes; mini, micro, and nano and fit into any type of device. For reference:
- 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 used by phones manufactured between 2012-2013, like the iPhone 4.
- 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 will 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 like 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!
