Which SIM?

If you're looking to purchase a SIM Only plan, your first step is to identify which SIM card you’ll need. This is determined by the device you are looking to use the SIM in, whether it’s a mobile phone, tablet or USB modem.

There are currently 3 main types of SIM cards which are used in most mobile phones, tablets and modems. These are:

  • Standard SIM
  • Nano SIM
  • Micro SIM

The different types of SIM cards along with some of the latest compatible handsets are summarised below.

TIP: If you're not sure which SIM card your new handset will require you can find this information within the 'Specs' tab on our product pages

Replacement SIM's

There may be some instances where you’ll need a replacement SIM card, such as if your phone is lost or stolen, or if you purchase a new handset SIM-free which requires a different SIM type i.e. like moving to an iPhone 5s (nano SIM) from an iPhone 4S (micro SIM).

In these instances the first thing you should do is contact your network provider and explain why you require a new SIM.

New SIM cards can usually be provided by your network free of charge, however this may vary from network to network.

We recommend visiting your network provider’s local store where replacement SIMs can usually be provided the same day, saving any delays in waiting for you new SIM to arrive.
