Port-in existing number
There are 2 simple ways to do it.
✅ Method 1 - You may visit our reseller outlets to request to port in your existing phone number to us. Check the popular resellers location here
✅ Method 2 - You may first order a simcard with us at at www.zym.sg. Once you've received the simcard, download ZYM Mobile app and follow the step-by-step instructions and choose to port-in your existing phone number to us.
A friendly reminder
After you've request to port-in to us, it typically takes up to 3 business days for the port-in to be successfully processed.
While waiting for your port-in status, you may start using the ZYM simcard right away as a temporary ZYM phone number is assigned to you. Alternatively, you may choose to continue to use your current Telco's simcard until it is no longer in service. This means the port in is completed.

It costs you nothing to port-in to ZYM Mobile!
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 if everything are good, you can expect your mobile number to be ported to ZYM up to 3 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.

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 between the entity between Telcos who facilitate this.
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.

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.
