Most networks require a minimum of 30 days notification by phone, email or letter of your intention to cancel your contract. During this period you will still be able to make use of your available services.
Step 1. Call your existing network provider to request cancellation. The network will inform you of any special requirements to do this.
Step 2. If you wish to keep your number ask the network for a PAC (Port Authorisation Code).
Step 3. If a PAC has been requested you will need to give this to your new network service provider. Read important information on Keeping Your Number. Please be aware that you will remain liable to pay off any outstanding line rental charges
