Mobile Billing Explained

If you're looking for information about call rates and other charges, you'll need to check the Critical Information Summary for your Westnet Mobile plan over on our legal page.

 

Westnet Mobile billing basics

Westnet Mobile billing has two main components;

  • Monthly plan fees ("Access fees") which are charged from the 1st to the 1st of each calendar month regardless of the billing period for your other Westnet services. They’re billed one month in advance.
     
  • Excess usage charges for any calls, SMS/MMS or mobile data used in the previous month. These are additional fees you incur when you exceed your monthly call/text or data allowance, or for usage that isn’t included with your plan such as premium services or international roaming. Learn more.

 

Your invoice after SIM card activation

New customers or Existing customers where SIM is activated BEFORE monthly invoice received

When your Westnet Mobile service activates, our billing system will align your mobile billing with the beginning of the next calendar month, then charge one month in advance.

This means that your next invoice will include:

  • Adjusted access fee for remainder of current month
    This covers the exact number of days remaining in the current month. You’ll also receive a pro-rata call and data allowance for these days.
     
  • One month access fee in advance
    As per our billing policy, services are charged one month in advance. If you ever change or cancel plans, or switch to another provider, any unused access fees you paid in advance will be credited back to your Westnet account.

Example: Your Mobile Voice is activated on the 5th of March.

Your invoice is raised on the 10th of March and it’s due 14 days later on the 24th of March.

It would include the following charges for Mobile Voice:

  • Adjusted access fee for remainder of current month – March 5 to April 1
     
  • Access fee one month in advance –April 1 to May 1

 

Existing customers where SIM is activated AFTER monthly invoice received

When your Westnet Mobile service activates, our billing system will align your mobile billing with the beginning of the next calendar month, then charge one month in advance.

However, if your Mobile service is activated after your invoice has been issued for the current month (but before it is due), then your Mobile fees will be delayed until your next invoice.

This means that your following invoice will include:

  • Adjusted access fee for previous month
    This covers the exact number of days that remained in that month. You would have also received a pro-rata call and data allowance for these days.
     
  • One month access fee for current month
     
  • One month access fee in advance
    As per our billing policy, services are charged one month in advance. If you ever change or cancel plans, or switch to another provider, any unused access fees you paid in advance will be credited back to your Westnet account.

Example: Your invoice is raised on the 21st of November and it’s due 14 days later on the 4th of December.
Your Mobile Voice Service is activated on the 28th of November.

Because your invoice was already raised on the 21st, it doesn’t include any charges for your Mobile Voice during November or December.

This means that your next invoice (raised December 21 and due January 4) would cover the following charges:

  • Adjusted access fee for previous month – November 28 to December 1
     
  • Access fee for the invoice issue month – December 1 to January 1

This scenario is as complex as mobile billing gets; because the invoice issue and payment dates span 2 months (December and January) that means truly paying a calendar month in advance means making payment for the full calendar month AFTER the payment due date.

  • Access fee for the invoice payment month (still won't be in advance at time of payment) – January 1 to February 1
     
  • Access fee one month in advance (at time of payment) – February 1 to March 1

 

Changing Mobile Voice plans

If you change your Mobile plan, you will receive a credit on your Westnet account for all unused access fees that you paid in advance. You will then be charged in advance at the rate for your new mobile plan.

This method ensures that you'll pay the correct rate for the exact days you had each mobile plan.

Please note that changing plans does not ‘reset’ your call and data usage to zero. You’ll receive a pro-rata amount of your new call and data allowance for the remainder of your current billing period. For example, instead of having 10 days’ worth of your old plan’s allowances left, you’ll have 10 days’ worth of your new plan’s allowances until your next billing period. Naturally this does not affect any allowances described as ‘unlimited’ in the plan details.

Example: Your current mobile plan has been paid in advance up to the 1st of July.

You change your mobile plan on the 25th of April.

Your next invoice would include the following credits and charges for your mobile plan:

  • Adjusted credit for old plan – April 25 to June 1
     
  • Credit for old plan – June 1 to July 1
     
  • Adjusted access fee for new plan for remainder of month – April 25 to June 1
     
  • One month access fee in advance for new plan – June 1 to July 1
