If your new service provider fails to meet promised quality of service, then you can reverse the porting (i.e. port back to your previous service provider) within 14 days of your porting having been completed. After that period has elapsed, you may not port the same number again (whether to your previous operator or to any other operator) for sixty (60) days after the port has completed.
The charges applicable to your service after switching will be on the terms and conditions of your new provider, and you will now be on their network. As such, charges may be different from those of your previous service provider, including increased charges for making calls from your new network to numbers on your previous network.
Not related to porting, however, note below that there may be contractual charges due as a result of ending your contract with your current service provider.
There is no charge for you to port your number. All porting charges are met by the network service providers.
Your porting process can be cancelled with no charge before you send the validation SMS to the special porting number 77678, set out in step 4 of the porting process (above). Once that SMS has been sent however, the process cannot be aborted.
No. Porting may happen on any business day.
The only disruption to your mobile service will be when you receive a text asking you insert the SIM card provided by your new provider. This process should take around 30 seconds and once your new SIM card is inserted and your handset is powered back up, your mobile service and number will have been ported.
