If you opted for port in during your SIM activation, your request shall be sent to your existing Telco immediately. Typically, you can expect your number to be ported to ZYM within 2 business days after you activated your SIM card. During this time, we shall issue a temporary ZYM number. Alternatively, you may continue to use your existing Telco's SIM card until the port in is completed.

ZYM Mobile is not responsible for port-in failures due to any wrong personal info provided or any obligations you may have with your existing Telco. Payments made prior to the port-in request shall not be refunded.

On the day of the port-in, both your port-in number and temporary number may be interrupted. This is normal and it usually takes 1 to 4 hours for your port-in number to activate.

Before you port over to us, please bear in mind that

✅ DO NOT cancel the mobile line that you have initiated to port in to us, please. We'll finish the procedure for you.
✅ The port-in number MUST be a postpaid mobile line registered under your NRIC/FIN.
✅ The port-in number MUST NOT have any outstanding balance with your current Telco.
✅ The port-in number NOT currently a suspended or terminated line.

It costs nothing at all to port over your existing mobile number to ZYM.

However, keep in mind that Early Termination Charges may apply if you have a contractual term with your current Telco, so make sure that your mobile plan and value-added services are not under contract with your existing telco.

Once you have initiated the port-in request, it may take up to 2 working days to be successful if all port-in conditions are met.

There are few possible situations where your Port in fails. The most common reasons include but not limited to:

✅ The port-in number is NOT under your provided NRIC / FIN or the personal info you've provided.
✅ The port-in has an outstanding balance or other obligations with your current Telco.
✅ The port-in number is currently a suspended or terminated line in your current Telco.

As such, ZYM Mobile is not responsible for port-in failures due to any of the above conditions. Payments made prior to the port-in request shall not be refunded.

We understand that sometimes things don't work out as planned, and if you've given ZYM a chance and decided it's not the ideal match for you, we're here to help you move on. You can terminate your plan and port out your number after 2 months, as per our Terms and Conditions. This is because we believe in giving our customers ample time to experience the ZYM difference before making a decision.

However, in case of exceptional circumstances that necessitate termination or porting out before the 2-month period, we may consider your request. Please be advised that any subscription fees paid upfront are non-refundable.
