I am looking to change my mobile service from Singtel to Starhub, and keep my primary number. So I want to share you my porting process.
Reason for the change if you are wondering - I am changing from Singtel to Starhub, mainly as I am in a new office to Fraser Tower and my 4G coverage for using mobile data is not optimal at the high level my office, when I am looking to tethering internet from my mobile for my laptop to have faster a internet. Note - It is a new building and up quite high, so my SingTel 4G/ 3G signals may be poor as a result of not having enough range of SingTel's current infrastructure in my new area.
So after going through the steps online via starhub.com, then you want to "Select Your Number" step.
Select Your Number with Starhub
- In "Select Your Number", select "Port from another telco".
- Enter your Singapore phone number under "Enter the 8-digit number"
- Select "Yes/ No" for whether you own this number for the question "Do you own this number?"
Great thing that they note here, is that you can "port any Singtel/ M1/ Circles.Life/ MyRepublic/ Zero/ Zero 1 Postpaid number to StarHub". There may be nuances around this for each telco provider, so be wary, especially with the less mature providers at the moment.
Then, you will receive details around the Number Porting Terms & Conditions that you will need to agree to, here are the details here so you know what to expect.

Additional information (optional context)
Essentially Starhub, M1, Singtel all follow IMDA's requirements. This is important given the stickiness requirement of your mobile number for online and modern services such as PayNow and SingPass. Essentially it is:
Full Mobile Number Portability is a solution that allows consumers to keep one mobile number for life, even when they switch operators. It works via a central database system in a multi-operator environment, in which all ported mobile subscribers’ numbers and routing information are kept. When a call/SMS/MMS is made to a ported mobile subscriber under the solution, the caller’s mobile operator will check against the central database information and route the call/SMS/MMS directly to the ported subscriber’s new operator.
Here's some details on some of these local telco's overall Full Mobile Number Portability guidance.
Starhub Full Mobile Number Portability guidance
1. What is Full Mobile Number Portability?
Full Mobile Number Portability is an enhanced mobile number portability solution that will allow you to retain full use of your existing phone number, even when you switch service providers. As such, you will not have to go through the hassle of updating all your contacts on a new number from your new service provider.
Prepaid and postpaid mobile subscribers can make use of this solution to retain their original phone numbers. However, the service is only applicable for prepaid to prepaid and postpaid to postpaid mobile subscribers only. (Starhub)
2. How is Full Mobile Number Portability different from the previous mobile number portability solution?
The previous mobile number portability scheme is based on a call-forwarding solution. As such, subscribers will possess two mobile numbers (the original mobile number and the new mobile number issued by the new service provider which they switched to). A call made to the original number at the previous service provider will be forwarded to the new number under the call-forwarding approach. When a subscriber under the call-forwarding solution makes a call or sends an SMS, the new number will be reflected on the recipient's phone. Furthermore, the subscriber will not be able to receive MMS on his original number with the call-forwarding solution.
The call-forwarding solution also only applies to post-paid mobile subscribers.
Full Mobile Number Portability will eliminate these limitations, and also extend mobile number portability to prepaid mobile subscribers. (Starhub)
