Nano SIM and Micro SIM cards

Physical SIM cards

SIM cards have come along way since GSM phones were first used in New Zealand.
We can help you if you've changed phones and need a different sized SIM card, and we can help you to move to eSIM if your phone supports it.

Nano-SIM

The smallest physical SIM card available is the Nano-SIM format.
A Nano-SIM card measures just 12.3 × 8.8 × 0.67 mm.
Most current mobile phones and mobile devices use a Nano-SIM slot.

If you have switched to a new phone, and you need a Nano-SIM to use it, we can help.
Simply visit us in store - and we can also help you to transfer your contacts.

If your phone or device needs a different sized SIM, we can help you with that too.

SIM stands for Subscriber Identification Module. It is a small card with an embedded chip that gets inserted into your mobile phone. Nano-SIM also has a technical name of 4FF (which simply means 4th Form Factor).
iPhone 5 was the very first phone to use the Nano-SIM sized card, way back in 2012.

Switch SIM size and keep your phone number.

You can keep your mobile number when you move to a new SIM card.

Before you start this change, you'll need your mobile phone and your new SIM card.

And this is true for eSIM as well. We can help you set up an eSIM on your phone. If you have an iPhone, you can use Quick Transfer.
