Activation & getting started

SIM cards come in three different sizes; the size you require depends on your phone. The three sizes are standard, micro and nano. 

Standard	Micro	Nano
The most common and largest of the three sizes. Commonly used in earlier smartphones and basic phones (e.g Telstra Flip/T96/Easy Call/Cruise, iPhone 3G/3GS, Galaxy S2)	Used in slightly older generation devices, and many of the mid-range smartphones (e.g Galaxy S4/S5/J1/J3, Note 4, iPhone 4, LG G4). This is the mid-sized SIM card	Used in most current and later generation major smartphones (e.g iPhone 5, Galaxy S6, Xperia Z3, LG G5 and later). This is the smallest of the three sizes

Most new SIM cards are multi-fit and can be used for all three sizes, by popping out the size for your device. It’s sometimes a good idea to keep the other pieces you pop out as you may use them in the future if you need to use your SIM card in an alternative device. 

Important: You shouldn’t cut a SIM card down in size. If you do so and it causes damage to your device, it may cause your device warranty to be voided. It may also cause the SIM card itself to fail.

The quickest way to get a new SIM card is to visit your local Telstra store and request a SIM replacement. It’s free, and your local store should be able to get the order sorted for you in a matter of minutes. Just make sure you take some ID with you so they can confirm you're the owner of the service.

If you’re unable to get to a Telstra store or you live in an area without one, you can also contact us to get a SIM replacement sent out via the mail. We’ll also give you the option to suspend your service until you receive the new SIM, just in case someone tries to use it.
