Mobile number portability lets you keep your existing mobile number when changing service providers. Taking your number to another provider is known as 'porting'.
Porting means you can shop around for the best mobile rates and services without the hassle of having to change your mobile number.
Before changing providers:
check that the provider can offer you the services and features you need
do not cancel your existing mobile service before changing providers. This will prevent you from keeping your existing number.
Current contractual obligations
Changing providers does not cancel your contract obligations with your current provider so you may still need to:
pay out your contract
pay an early termination fee
pay outstanding call charges.
Your existing provider cannot refuse or delay your request to move your number to a new service provider because of any outstanding debt.
You may choose to wait for your existing contract to expire before changing providers, but you should make sure you still have an active service (do not disconnect your service).
You can only change providers and port an existing mobile number if you are the authorised customer, that is, the person who has the mobile service account with the existing provider.
Porting a pre-paid service
A mobile number issued to a customer as part of a pre-paid service can be ported to a new provider.
Handsets sold as part of a pre-paid service are often 'Network locked'. If you want to use the same handset you may need to make arrangements with your existing service provider to have your handset unlocked. A fee may be charged.
Before changing providers ask yourself:
When does my existing mobile service contract expire?
Will I have to pay an early termination fee or ongoing costs (access charges) under my existing mobile service contract if I move my number to a new provider?
Is my handset SIM locked and will I have to pay to have it unlocked before moving my number?
Am I the authorised customer?
What do I want from my mobile service? Which provider best meets my needs?
If the new provider fails to warn you that you may have existing contractual obligations or you do not properly authorise the transfer of your existing mobile number you do not have to proceed with the move.
Keeping your existing mobile number
When you contact a new provider for a mobile service and want to keep your mobile phone number, the provider is obliged to:
advise you that you may have outstanding charges payable or unfulfilled obligations with your existing provider and
ask you for authorisation confirming your request to change providers and keep your mobile number.
Confirmation of authorisation may be:
written (for example, where you sign a form)
electronic (for example, where you agree to certain conditions on the Internet before proceeding) or
voice (for example, where you agree to certain conditions described to you over the telephone by an operator or a voice recording).
The new provider will also:
make sure your personal information is correct
send messages to your existing provider to confirm your request.
Your existing provider will arrange for your phone number to be moved to the new provider. The new provider will make arrangements with other carriers for you to receive calls on that number with your new service.
You do not have to proceed with the move if:
the new provider fails to warn you of existing contractual obligations
you do not properly authorise the transfer of your existing mobile number
If you believe your mobile number was moved without your authorisation you should contact your existing provider.
How long should it take to move my number to a new provider?
Most changes take a few hours, but delays may be caused by system interruptions or periods of high demand.
Can I get a new handset when moving my number to a new provider?
Yes. In most cases you will be entering into a new relationship when you move to the new provider and that is often the point at which customers decide to get a new handset. However, if you are getting a new handset, you should check the contract to see if you will be paying for that phone.
Other factors to consider
Existing contractual terms and conditions
Check all terms and conditions of:
your existing contract
the new contract.
Service providers have to provide information about contract terms and conditions quickly and free of charge to their customers.
Taking advantage of special call rates/free calls on same network connections
Some mobile providers offer special low call rates between same network connections, making these calls very attractive. The ability to recognise networks is lost with number portability. To avoid unexpected call charges, mobile users should check with the person they are calling as to whether they are using the same mobile network.
Inclusion of mobile numbers in telephone directories
Mobile phone numbers are included in telephone directories on an opt-in (customer choice) basis, free of charge. Directory listing can be arranged with your current provider.
