SIM Card Size

There are three different SIM card sizes: Standard, Micro and Nano. The best way to find out the size of your SIM is on the packaging your phone came in or the website for your phone type. Here are some general tips that might help you:

  • Standard SIM – will fit most feature phones
  • Micro SIM – will fit most Android or Windows phones (including iPhone 4/4S, Samsung Galaxy S4 and Samsung Galaxy S5)
  • Nano SIM – will fit most iPhones (eg. iPhone 5 and iPhone 6 Plus)

Boost SIM packs come in three different types:

  • Trio SIM – can be used for all SIM card sizes. Simply pop out the SIM size you need.
  • Multi SIM – can be used as a standard or micro SIM card. Simply pop out the SIM size you need.
  • Nano SIM – can only be used as a Nano SIM.

Common Questions

How do I replace a lost SIM?

If you’ve lost your SIM or got a new phone and your SIM card doesn’t fit, don’t worry. We can organise a new SIM to be sent out to you ASAP.

All you need to do is contact our customer care team on 1258881 or live chat and let us know what type of phone you have or what type of SIM you’re after. We’ll send it out to you.

The new SIM, once activated, will replace your old one. This means everything on your account will stay the same, including your phone number and any credit balance you may still have.

How do I keep my existing number when moving over to Boost?

Porting your number across to the new Boost Pre-paid Mobile service is as easy as:

  1. Check that your phone is unlocked and 850MHz compatible
  2. Grab a Boost Mobile SIM pack from a participating retailer, or online at
  3. When activating your SIM, select the “Bring my phone number” tab. You need to make sure your name and DOB match up with your existing account – and if you’re porting over from a post-paid account, you’ll need your account number. Have your SIM serial number handy for the operator – you’ll find it on your Boost Mobile SIM pack.
  4. If your phone is 850MHz compatible but was previously used on a different network, you’ll need to change some settings for it to work on the Telstra 4G Mobile network.

If you are porting from Telstra to Boost Mobile, you will need a blank Boost Mobile SIM card from Customer Care. Click here for more information.

Bear in mind, porting can take up to 48 hours to complete.
