No, you cannot.

There are no ‘hidden’ costs or charges related to porting. However, you must meet your contractual charges which you have with your provider prior to porting. There may be contractual charges due as a result of ending your contract prematurely with your current service provider. You are advised to investigate these charges before deciding on whether you should port your telephone number.

Contractual charges may consist of payments for purchasing a service or bundle at a discounted price and charges arising out of the Terms and Conditions of your service with your provider.

The charges applicable to your service after porting your telephone number will be based on the terms and conditions of the package you agree to with your new service provider. Charges may be completely different from those of your previous service provider, including increased charges for making calls from your new provider’s network to numbers on your previous provider’s network. You are advised to compare charges before making a porting request.

No. However, where you have an existing contract, you will be required to settle in full any early termination charges. In addition, bills for usage up to the time of the port will be sent to you for payment. You are reminded that you have an obligation to clear any legitimate outstanding billed balances with the previous provider prior to making your porting request.

Where you have requested and received a port to your new service provider, you cannot be billed by your old provider for monthly line rental after the date and time of being ported and activated by your new provider. Your new provider will begin billing you from the time of porting.

You should check the terms and conditions of your contract with the service provider before porting your telephone number.

You will be denied porting your telephone number for any of the following reasons:
a) Your number has been barred or suspended from service.
b) Your account has unpaid billed balances.
c) Your contract has not yet expired. You must pay off all outstanding balances and terminate your contract (not your service) before you request to port your number.

Yes. You may port your number providing it has not been barred or suspended from making outgoing calls once all invoiced amounts not in dispute are settled. You remain liable to pay any outstanding balance due to that provider, depending on how the matter is resolved.

No.

No, you request your port from your new service provider to which you are moving.

No, and you should not. When you sign your porting request form, you are authorising your new provider to instruct the former provider to disconnect the service when the port takes place. If you have outstanding contractual charges, these will have to be paid before you make the porting request. Otherwise, your porting request will be rejected.

Your application is submitted to your current provider by your new provider for approval. Whether you are an individual or corporate customer, prepaid or postpaid, the process should take no more than five working days.

You will be able to use your current provider’s service. You will be liable to pay for the usage of this service between the initiation of the port request and when the port is finalised. You will be liable to pay for the usage of this service between the initiation of the port request and when the port is finalised.

Note: your current service provider will issue a bill for the unbilled usage on your Fixed line account even though you have moved to a new service provider’s network. You are liable to pay this bill. This is one of the conditions on the Porting Request Form.

Yes.

No. A broadband service will have to be requested from your new provider.

Your porting request cannot be cancelled after porting request forms are completed, signed and submitted at the new service provider’s office.

You cannot port again unless six months has elapsed from the date of your last port.

Quality of service issues should be reported to your new service provider within ten working days of your telephone number being switched over to their network. Should the new service provider be unable to resolve these issues to your satisfaction within five working days of your report, a request can be made to the new service provider for an emergency port back to the original service provider.

After returning to your original service provider due to service issues, you will be allowed to port again without having to wait the six-month period.

During the porting process, your former service provider is only allowed to contact you to recover outstanding payments. Otherwise, your former service provider is not permitted to contact you during the porting process.

No. Initially, local toll-free telephone numbers will not be ported.

All communication concerning the porting process should happen ONLY between you and your new service provider.
