How to Switch Mobile Provider and Keep Your Number Australia

Updated April 2026 · 5 min read

Are you feeling stuck with your current mobile provider, perhaps paying too much or getting less data than you need? Many Australians believe switching means losing their familiar phone number, but that's simply not true! This guide will walk you through the simple process of how to switch mobile provider and keep your number in Australia, ensuring a smooth transition to a better deal.

The Simple Steps to Port Your Number

In Australia, thanks to number porting regulations, you absolutely can keep your existing mobile number when moving to a new service. The process is designed to be straightforward and consumer-friendly. Here's a quick overview of how it works:

1. Choose Your New Provider and Plan

Before you do anything, decide which new provider and plan best suit your needs. Consider factors like data allowance, network coverage (many smaller providers use the same networks as Telstra, Optus, and Vodafone!), and monthly cost. For example, you could get unlimited data from Felix Mobile for $40/month, or access the Telstra network through ALDI Mobile for just $23/month.

2. Order Your New SIM or eSIM

Once you've picked a plan, order a new physical SIM card or activate an eSIM with your chosen provider. Most providers now offer eSIMs, making the switch even faster as there's no waiting for mail.

3. Initiate the Porting Process During Activation

When you activate your new SIM or eSIM, you'll be asked if you want to keep your existing number. This is where you tell them you want to "port" your number. You'll need to provide some details from your old account, like your account number or a recent bill, to verify your identity.

4. Keep Your Old Service Active

Crucially, do NOT cancel your old service before the porting process is complete. Your old number must be active for the transfer to occur successfully. Your new provider will contact your old provider to facilitate the transfer.

5. Wait for the Switch

Mobile number porting usually takes anywhere from a few minutes to a few hours, though it can sometimes extend to one business day. You might experience a brief period of downtime (a few minutes) when your number is officially transferring. Once your old SIM stops working and your new one activates, the switch is complete!

Why Switch? Same Network, Less Money

Many Australians are paying too much for their mobile plans when they could be getting the same great network coverage for less. Mobile Virtual Network Operators (MVNOs) like Boost Mobile, ALDI Mobile, Amaysim, and Felix Mobile operate on the exact same infrastructure as the major networks (Telstra, Optus, and Vodafone) but often offer significantly cheaper plans.

For example, if you're on a major network and paying $50 for 20GB, you might find a plan from an MVNO offering 30GB on the same network for only $30. It's a smart way to save hundreds of dollars a year without compromising on reliability or convenience. With options like Lebara offering 15GB for just $9/month, or Woolworths Mobile giving you 22GB on the Telstra Wholesale network plus a 10% grocery discount, there's always a better deal to be found.

Don't let the fear of changing numbers keep you from a better deal. It's easier than ever to switch and save!
