Port-in existing number
ZYM Mobile has a hassle-free online port-in process.
✅ Step 1: Order a SIM card in www.zym.sg.
Choose to have it deliver to you via your mailbox or doorstep.
✅ Step 2: Download ZYM Mobile App
While waiting for your SIM card to arrive, download ZYM Mobile App in Appstore or Playstore. You will need it to self-activate the SIM card later.
✅ Step 3: Activate the SIM card
Once you've got the SIM card, follow the instruction on the SIM pack to kick start the SIM activation process. From there you may choose to port-in your existing number (Must be a postpaid number) to ZYM Mobile. Once done, your port-in request shall be submitted to the Telco you are currently with.
While waiting for your port-in status, you may start using ZYM SIM card with a temporary assigned phone number. Alternatively, you may choose to continue to use your current Telco's SIM card until it is no longer in service. This means the port in is completed.
A friendly reminder
It typically takes 1 - 2 business days from the day you've activated the SIM card for your port-in request to be successfully processed.

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.
