Has your activation request...

Successfully submitted but your service is not active

These tips resolve most questions we get about activation. Have you:

  • Allowed enough time for activation to complete? It can take 15 min to 4 hours unless porting out of business hours (times below).
  • Switched your device off and on again, every now and then?
  • Sync'd your phone with any companion software it may have? (eg. iTunes, Kies, etc)
  • Inserted your new SIM card correctly?

Give us a call if you need help, our contact details are below.

Failed or you've received an error when requesting activation

These may sound silly, but it's best to double check that...

  • You're entering the SIM card number and any other requested details correctly
  • You're activating the right type of SIM for your service. (eg. a Prepaid SIM for a Prepaid service)
  • Likewise for Mobile Broadband / Mobile Phone as these SIM cards are not interchangeable
  • If porting, make sure that you're entering your previous service provider's account and personal details correctly. 

Give us a call if you need help, our contact details are below.

Activation & Porting times

Activation normally occurs within 15 minutes to 4 hours, unless you're transferring (porting) your number over from another phone company outside of these times.

  • Mon to Fri: 8am – 8pm

If you request to port your number outside these hours, your service will remain active with your existing provider until the next porting day.
