This guide explains your options clearly and legally and how an E.Tel mobile plan can make it simple.
1. Use a Dual SIM Phone
Modern smartphones support Dual SIM, meaning you can have:
One physical SIM and One eSIM, or
2 eSIMs
On iPhone and many Android devices, you can choose which number to use before placing a call.
How to choose which number to call from (iPhone)
Open Contacts
Tap the contact
Tap the current phone number label
Select the other line
Place the call
This allows you to call from a different number without changing phones.
With an E.Tel Mobile plan, you can run an affordable secondary number without paying for excessive data you don’t use.
2. Hide Your Caller ID (Call From a Private Number)
If your goal is to prevent the other person from seeing your number, you can hide your caller ID.


On iPhone:
Go to Settings
Tap Phone
Select Show My Caller ID
Toggle it Off
On Android:
Open the Phone app
Tap the three dots (menu)
Go to Settings
Select Calling Accounts or Supplementary Services
Choose Caller ID
Select Hide Number
This will hide your number for all outgoing calls until you turn it back on.
3. Use a Second Mobile Plan
If you regularly need another number for:
Business calls
Online marketplace transactions
Temporary projects
Travel
Privacy separation
The most reliable solution is having a second SIM.
E.Tel specialises in affordable smaller mobile plans, so you can maintain a second number without overpaying.
Benefits of a second E.Tel number:
Separate work and personal calls
No expensive big-data commitments
Flexible plans
Reliable coverage on the Optus 4G Plus network
4. Use Internet Calling Apps
Apps like WhatsApp, Skype, or other VoIP services allow you to call using internet data instead of your primary mobile number.
However:
Call quality depends on data strength
The recipient may need the same app
Not ideal for urgent or official calls
A proper secondary SIM is more stable and professional.
5. Can You Temporarily Change Your Number?
No! Mobile numbers cannot be temporarily changed for outgoing calls.
If you need a different caller identity, your options are:
Dual SIM
A second SIM
VoIP app
Caller ID suppression
Why Many Australians Use a Second SIM
Common reasons include:
Running a side business
Selling items on Facebook Marketplace
Online dating privacy
Managing family members’ accounts
Separating work and personal life
A low-cost secondary plan makes this practical.
Why E.Tel Mobile Is Ideal for a Second Number
Unlike major providers that push large data bundles, E.Tel offers:
Budget-friendly smaller data plans
No unnecessary overpaying
Reliable 4G Plus coverage
Simple, flexible options
If your second number is mainly for calls and occasional data, you don’t need a 100GB plan.
E.Tel keeps it simple.
Final Thoughts
Calling from another number is straightforward when you understand your options.
For occasional privacy, caller ID suppression works. For regular use, a second SIM is the most reliable and professional solution. If you’re considering a second number, choosing a flexible and affordable plan makes the difference.
E.Tel Mobile plans are designed for Australians who want value without paying for data they don’t need.
