SIM Cards

Getting the right size SIM card for your smartphone or tablet

Standard, Nano, micro and eSIM - what do I use?

As technology advances and smartphones become more powerful, SIM cards are changing. Not only are physical SIM cards getting smaller to take up less hardware space, but most phones are also now dual-SIM - meaning they have both a physical SIM card slot and a digital eSIM already built in.

At the moment, physical SIM cards come in three sizes:

  • Standard SIM
  • microSIM; and
  • Nano SIM

If you're unsure what SIM to use for your device, you're in safe hands - our Multi-SIM card contains a Standard, micro and Nano SIM. And if you choose an eSIM, you won't need to worry, as you won't use a physical SIM for your device.

Whichever option you go for, you won't need to get a new SIM card if you change phones in the future.

Can I put any SIM in my device?

The SIM you'll need depends on the make and model of your phone or tablet. Our Multi-SIM will fit any of your devices, as it can be turned into any SIM size. If you need it to fit your iPad Mini or iPhone 5 for example, you can convert your SIM or micro sim to a Nano SIM, and you're good to go.

But if you choose an eSIM, you'll need a phone that's eSIM compatible. Check out the list of compatible devices.

Where can I buy a SIM that fits any phone or tablet?

Where does the SIM card go?

Every phone and tablet model is designed differently, so there isn't one universal location for your SIM card. For more help, check out our device guides

Existing customer in need of a new SIM card?

Simple, you can easily swap your old SIM card to a new one or to an eSIM, using our SIM swap tool. A SIM swap lets you keep your current Vodafone number when you get a replacement SIM. You'll need to do this if you have a new device that requires a different sized SIM (for example if you've upgraded), if your device is lost or stolen, or if your SIM is damaged.

How do I get eSIM?

You'll need an eSIM compatible phone. Check out the list of compatible devices.

You can swap your plan from a physical SIM to an eSIM in your My Vodafone account at any time.

eSIM leaves space in your phone for a physical SIM card, so you can use two numbers without needing two phones - perfect for business or roaming. Just make sure your phone is dual-SIM compatible first.

The different SIM types

Standard SIM

This is the largest SIM type around now. These were introduced in 1996, and they are still used in some older smartphones today such as the iPhone 3GS, Blackberry Curve, and Samsung Galaxy Note.

Micro SIM

microSIMs are used in many smartphones today but they are no longer the smallest size. Introduced in 2003 to save space, they were used for almost ten years. They are found in phones like the iPhone 4s and Samsung Galaxy S5.

Nano SIM

The Nano SIM was released in 2012 and, to date, it is the smallest SIM around - even in its thickness. This SIM is used in most smartphones today, from the iPhone 5 upwards, and in most android phones including the Samsung Galaxy S7 and Google Pixel.
