The new MyZone train fare technically increase to most number of people than those who were able to save if you are going to analize the changes closely.

Before MyZone:
I pay $139.00 - monthly ticket (28 days)

With MyZone:
I pay $148.00 - monthly ticket (28 days)

Increase by $9.00 monthly expenses.

Here is a tip to save for your train fare if you don't want to buy quarterly or annually.

* Buy single trip when going to work and buy weekly train when going home (after 3 pm).
- Buying weekly train ticket after 3pm covers your train faire going back home and the ticket officially starts the next day.

Example:

Travel from Oatley to Chatswood:

***
MyTrain    Adult
Single    $4.60   <--------
Return    $9.20
Weekly    $37.00  <--------

***
MyTrain            Adult
Monthly (28 days)    $148.00
Quarterly (90 days)    $407.00
Yearly (365 days)    $1,628.00

No savings made when buying monthly (28 days) ticket: $37.00/weekly x 4weeks = $148

MyTrain            Adult
Monthly (28 days)    $148.00     <--------
Quarterly (90 days)    $407.00
Yearly (365 days)    $1,628.00

Note: you have to pay some admin fees if you lost your weekly/quarterly/monthly ticket that is why quarterly and annually is not advisable to use.

Technically, train ticket is used when going to work (5 days a week)

$37.00 / 5 days = $7.40 per working day is the total cost of a return trip.

* If I buy single trip on Monday(19-Apr) going to work: $ 4.60
* Then I will buy weekly train ticket when I go home (after 3 pm): $37.00
Note: Weekly tickets bought after 3pm can be used on the same day and the official start date will be the next day.

- I can use the weekly ticket going home (19-Apr) and the official validity of the ticket is from 20-26Apr (7 days).

Total cost for 6 working days: (19-26Apr / Mon,Tue,Wed,Thu,Fri,Mon) / exclusing Sat and Sun
$4.60 single + $37 weekly train fare = $41.60 (cost of train fare for 6 working days)

$41.60 / 6 working days = $6.93 per day.

There are about 20 working days in 28 days.
$ 6.93 per day x 20 days = $138.60 train fare for 20 working days.

Comparison per working day :
$ 7.40 per day - If you are going to buy weekly train ticket
$ 6.93 per day - If you are going to buy single + weekly train ticket
------------
$ 0.47 savings per day.

Comparison per Month (28 days):
$148.00    - buying monthly (28 days) train ticket
$138.60 - buying single + weekly train ticket (28 days)
---------
$ 9.40 savings per month

Here in Australia, it is possible to transfer your phone number from one service provider to another. This way, you can keep your phone number with you even if you decide to change providers. 

Usually, there is are no additional charge involve in porting your existing mobile number to another service provider. You can even change the ownership of the phone number (some providers charge a fee for change of ownership).

Virgin mobile will charge $25 if you want to request for change of ownership.  Optus does not charge for the change of ownership. I heard that Telstra does not charge as well.

From experience it only took a few hours for the transfer from one service provider to another to complete and it took less than a day for the change of ownership to complete .

Some providers provide phones that are lock to their services and charge fees to unlock the phone. Some has policies that you need to consume a certain amount before they can unlock the phone for free or you need to stay with them for a certain period of time.

Virgin mobile provides unlocked phones. You can use other SIM on their phone.

Here in Australia, I notice that you need to register your personal details in activating your pre-paid SIM card/number.

In Phils, you don't need to register pre-paid SIM.

I just notice this week that even if you are using pre-paid SIM, you can still track your calls for the past seven days (with Vodafone).
