Before you port over to us,

Do not cancel your current mobile subscription)
To port in to ZYM, your current mobile subscription with the existing Telco MUST stay active. Once you've initiated to port in to us, we'll finish the procedure for you.

Make sure the port-in number is a postpaid plan
As ZYM only offers postpaid subscription, it is important to know that your port-in number MUST be a postpaid mobile line registered under your NRIC/FIN.

Your port-in number must not have any outstanding obligations
Though depending on the commercial agreement with your existing Telco provider, you are to take note that your port-in request to ZYM may be rejected by your current Telco if you have any outstanding obligations. i.e Outstanding bill / Still under contract.

The port-in number NOT currently a suspended or terminated line
Under these circumstances, your port-in request will be rejected if the port-in number is not "active" in your existing Telco.

You are to be reminded that ZYM Mobile is not liable for any delay / reject of port-in request if any of the above conditions are not met. No refund on prorate, advance or any relevant usage charges shall be given under this context.

Other than current month prorate and advance month subscription fee, 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.

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 mobile 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 and your SIM subscription with ZYM starts. Alternatively, you may continue to use your existing Telco's SIM card until the port in is completed.

As stated, 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. No refund on prorate, advance or any relevant usage charges shall be given under this context.

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.

Anyone over the age of 18, with a valid NRIC / FIN can sign up for a ZYM subscription.

Anyone at least 18 years old can sign up a ZYM subscription, both locals and visitors.

All you need is a valid NRIC / FIN or Singpass, and a Mastercard or Visa credit / debit card.

Note: If you are a non-singaporean / PR, you must have at least 6-month of Pass validity to sign up a ZYM subscription.

Under the most recent update in our communication regulation, the max number of ZYM subscription per NRIC / FIN is 10.

It's best to stick to what you can handle, though.

There are 2 possible situations where your Port in fails. The most common reasons include but not limited to:

Information mismatch

Please contact your current Telco to verify and update us on the correct information if necessary. Once your details are consistent, we will resubmit your port-in request again.

You are under obligations
Either you have an outstanding bill balance or you are current still in contractual term with your current Telco. Please contact your current Telco to make necessary arrangement and let us know again for a port-in resubmission.

The port-in number is no longer active
If port-in number is a suspended or terminated in your current Telco, we wouldn't be able to complete your port-in. Please contact your current Telco to make necessary arrangement and let us know again for a port-in resubmission.

You are to be reminded again that ZYM Mobile is not liable for any delay / reject of port-in request if any of the above conditions are not met. No refund on prorate, advance or any relevant usage charges shall be given under this context.

We're sad to see you go, though. Do be informed that ZYM does not restrict our customers from porting out unless there are certain forms of obligations in place.

The common reasons are:

👉 Information mismatch
The name or identification number (NRIC/FIN) you provided to the Telco you wish to port in to doesn't match with ZYM Mobile's records.

👉 Obligations
You are having some contractual obligations or pending bill payments with ZYM Mobile.

👉 System delay
While rare, there could be a system delay in the Telco you wish to port in to.

In summary, it is wise to check with the Telco you've requested to port in to. They will be able to advise you on the exact reasons why your request has been rejected.

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 (Minimal subscription for a non-contract plan is 2-month).

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 / roaming services utilisation are non-refundable / waiverable.

To initiate, simply reach out to our ZYM customer care @ Whatsapp 80404040. We're always here to assist you, even if it means bidding farewell.
