- If I had ported out my Zero1 number to other mobile operator, can I port back to Zero1?

Yes. We welcome you back. You can re-register as per normal with us by submitting a port-in request during the online registration. However it is subject to the approval of your current mobile operator and that you had last ported out from Zero1 more than 3 months ago. Please check your number fulfills the port-in conditions.

If you had last ported out from Zero1 less than 3 months ago, there will be a one-time registration fee of $10.70 and $32.10 for the cost of the SIM card. Any unpaid charges from your previous bills will also be charged to you in addition to other administrative charges, if applicable.
