Mobile Broadband FAQ

This article will answer some frequently asked questions about iiNet Mobile Broadband service. 

IMPORTANT: As of 13 October 2015, Mobile Broadband hardware and services are no longer sold by the iiNet Group, however existing customers may continue their service and request a replacement SIM card if necessary. Existing Mobile Broadband customers can view and swap plans in Toolbox (My Products > Broadband > Change plan) or by calling us on 13 22 58.

If you already have Mobile Broadband with us, you'll find some help with setting up and troubleshooting on iiHelp.

Once you have your iiNet Mobile Broadband SIM card, you’ll need one of the following hardware options:

  • A USB modem (dongle) and a computer/device with a USB port
  • WiFi hotspot and a WiFi enabled computer/device
  • Compatible tablet device with a SIM card slot

Please note that the computers and devices you need will need to meet one of the minimum operating software requirements:

  • Windows XP or more recent version
  • Mac OSX 10.2 or more recent version
  • Android OS

You can, but it may not work. iiNet Mobile Broadband operates on the Optus Mobile network, and only the Optus-approved Huawei and ZTE modems that we previously sold have been tested for use on this network.

As of 13 October 2015, iiNet no longer sells mobile broadband hardware. We recommend checking with the seller of any mobile broadband hardware you're looking at buying to confirm it will work with a mobile broadband service on the Optus network.

Check your location on our coverage map. It’s updated directly from our network wholesaler, Optus.

The Optus 3G network currently covers 98.5% of the population in Australia. Optus plans to continually upgrade sites to increase 4G coverage in the future.


No, but it is worth noting that all Mobile Broadband hardware previously purchased from iiNet is not locked to a specific provider. That means you may be able to use the hardware while overseas with a SIM card purchased in that country (subject to network compatibility).

You can track your usage by logging in to Toolbox, but please note that these records may be delayed by up to 48 hours.

Once the quota is exceeded, your Mobile Broadband service will begin accruing excess charges. The service will not be “shaped” (speed restricted).

iiNet is required to notify you by email and SMS once you reach 50%, 85% and 100% of your monthly quota.

By default, once you exceed your included plan value by $200 we will restrict your Mobile Broadband service. This amount is known as an excess spend limit or unbilled usage limit and can be changed by calling us on 13 22 58.

For our most recently discontinued mobile broadband plans, 3G excess usage is charged at 5c per MB and 4G excess usage charged at 2c per MB.

Excess data may be charged at a higher rate on older discontinued plans.


Tethering allows you to use a mobile phone or mobile tablet device as a USB modem or WiFi hotspot to connect another device to a Mobile Broadband service (e.g. desktop PC). iiNet does not recommend or support tethering for Mobile Broadband or Mobile Voice data - on some devices (e.g. iPads, iPhones) the Mobile service does not allow tethering.
