- I received Zero1 SIM card, what should I do?

Upon receipt, please go the Zero1 app and select the "SIM Activation" icon to activate your SIM card. Alternatively, go to the SIM activation page here https://zero1.sg/activate and login to your Zero1 account.

You will need to verify your personal information via Singpass to complete activation.

For new numbers: Your SIM card will be activated immediately.

For port-in numbers: Your SIM card will be activated within 1-3 business days.

If you collected your SIM at Mosi Mosi or ShortQ on a Friday / Saturday / Sunday, you may only initiate the activation request after 2pm on the following Monday, which is the next business. This applies to both new lines and port in mobile services.
