How we calculate total minimum cost: Your min. cost is the minimum total amount you will be required to pay, when you sign up to a SIM plan or a SIM plan with a device payment plan.

• When you sign up to a month to month SIM plan without a device payment plan, your min. cost is one month of your SIM plan fee.
• When you sign up to a month to month SIM plan (which includes a plan fee discount) without a device payment plan, your min. cost is one month of your discounted SIM plan fee.
• When you sign up to a month to month SIM plan with a device payment plan, your min. cost is the cost of your device in full plus one month of your SIM plan fee.
• When you sign up to a month to month SIM plan (which includes a plan fee discount) with a device payment plan, your min. cost is the cost of your device in full plus one month of your discounted SIM plan fee.
• When you sign up to a month to month SIM plan with a device payment plan (which includes a device discount), your min. cost is the cost of your device in full (less one month of your device credit amount) plus one month of your SIM plan fee.
• When you sign up to a month to month SIM plan (which includes a plan fee discount) with a device payment plan (which includes a device discount), your min. cost is the cost of your device in full (less one month of your device credit amount) plus one month of your discounted SIM plan fee.

No other discounts or bonus offers are factored into your min cost.

Changes to Plans (month to month): We may make changes to your month-to-month data plan, including to the price or inclusions. This could include moving you to a new plan, which may cost more. We’ll give at least 30 days’ notice of any increase to plan access fees, any data inclusion decrease, or any plan moves.  If you don’t like the change, you can choose a new plan (once per payment cycle) or cancel your plan.

Optus Choice Plus Watch Plan: Available to eligible new and recontracting customers who also sign up to a 12, 24 or 36 month eligible device payment plan with Optus. If you need to cancel your plan, there are no plan cancellation fees but you will not receive a pro rata refund for the remainder of the payment cycle, unless otherwise provided in our standard agreement and subject to your consumer law rights. Your related device payment plan will be cancelled and you'll have to pay out any remaining payments owing as a one-off payment with any device credits or discounts forfeited. You will be automatically charged via card on your monthly invoice date. You must maintain your card payment details or your plan will be cancelled. Limit of one Optus Choice Plus Watch plan per eligible device payment.

Device Payment Plans (OptusPay): You must have an eligible Optus plan to add a Device Payment Plan. If you need to cancel your Device Payment Plan before the end of the agreed term, or you need to cancel your related eligible Optus plan during the Device Payment Plan term or you want to move to an ineligible plan during the Device Payment Plan term, then you’ll need to pay out the full remaining cost of your device. Device credits or discounts that Optus was going to cover do not apply in these cases. Limit of one related device payment plan per Data plan. You will be automatically charged via card on your monthly invoice date. You must maintain your card payment details or your plan will be cancelled.

Device Discount: If you have device discounts, they will apply for the duration of your device payment plan. If your device payment plan is cancelled before the end of its term, you will need to pay out the remaining device payments in full in your next payment and any applicable discounts will be forfeited.

Optus Number Share: Compatible connected wearable devices use Number Share functionality to access the Optus Mobile Network. The wearable device is not the same as a mobile phone and some network functionality is not available on these devices. Call quality may not be of the same standard as a mobile phone and may drop out in certain areas. Requires a compatible wearable device and compatible mobile phone with selected operating systems. Only available if you have or sign up to an eligible mobile phone plan and use your phone to sign up via the app. Your phone must have Voice over LTE (VoLTE) functionality which must be enabled on your device. If you cancel your Number Share Bolt-on or your mobile phone plan to which the bolt-on is attached, the number sharing functionality will not be available on your wearable device. Number sharing functionality is only available for use in Australia. Optus Number Share is a month-to-month option which is normally $5/mth but is available at no additional cost on the Watch plan. You will be automatically charged via card on your monthly invoice date. You must maintain your card payment details or your add-on will be cancelled.

No Excess Data Charges: If shared data allowance is exceeded, all shared data services on your account will be slowed to a maximum speed of 1.5Mbps (suitable for general internet browsing and music streaming, however some activities such as video streaming may see increased buffering and loading times). Usage while slowed is unmetered. Applies to data usage in Australia only.

Optional Extras For Optus Choice Plus Watch Plan: Optional Extras are available on a month by month basis and do not form part of your plan. You may cancel them at any time. Optus may change or withdraw an optional extra at any time and we will try and give you at least 21 days prior notice of a change. If an optional extra is cancelled, changed or withdrawn, you will be liable to pay charges for the optional extra service that remain active until the relevant payment cycle ends and your plan will continue for the rest of its term.
