Port Your Number Easily in Singapore – A Complete Guide

What is Number Porting?

Number porting, also known as Mobile Number Portability, is the process of switching to a new telco while keeping your existing mobile number. Instead of getting a new number, you retain your current one, making the transition seamless and hassle-free.

This is especially useful because it saves you from the inconvenience of updating your contact details across multiple platforms, including social media, banking apps, and two-factor authentication services.

In Singapore, number porting is widely supported across all major telcos and is typically completed within a few hours to a day. Both prepaid and postpaid users may be eligible, depending on the telco’s specific policies.

Top Reasons People Choose to Port Their Number

Better data deals or coverage

Many users switch to take advantage of more generous data allowances, faster speeds, or stronger network coverage in their area.

Moving from contract to no-contract plans

Some customers prefer the flexibility of no-contract plans, allowing them to change or cancel their service without penalties.

Converting from postpaid to prepaid or vice versa

Number porting makes it easy to change your payment model without losing your mobile number.

Desire for better customer service

Poor customer support is a common reason people move to a new telco that offers faster, more responsive service.

Why Porting Is More Relevant Than Ever in a Digital-First Singapore

In 2025, Singaporeans are switching mobile providers more frequently than ever. Why? Because the market now offers a wide range of SIM-only, eSIM, and lifestyle-bundled mobile plans that go beyond just data and talk time. Today’s mobile user wants perks that integrate into their daily routine—from streaming to ride-hailing.

Telcos like Circles.Life have capitalized on this by offering bundled ride credits, such as TADA voucher codes and marketplace discounts, making them attractive options for users seeking both affordability and convenience. Porting your number allows you to retain your current mobile identity while enjoying these expanded benefits.

Number Porting: How it Works (Step-by-Step)

Step 1: Submit a porting request

Once your Circles.Life SIM or eSIM is active, open the Circles.Life app on your mobile phone. Log in using your assigned number, then go to Profile > Account > Port-in number.

Step 2: Verify ownership and fill in your number details

Enter your current number, select if it is postpaid or prepaid, and choose your donor telco and porting date. Make sure your number is still active and registered under your name with your current telco.

Step 3: Wait for approval and system transfer

Once submitted, Circles.Life will contact your current provider and handle the switch. Porting usually completes within a day. Keep your old SIM active during this time and do not manually terminate your current number, or the request may fail.

Step 4: Complete the transfer

You will receive confirmation via SMS or app once the port is successful. Your existing service will be automatically terminated, and you can begin using Circles.Life with your original number.

Porting Between Prepaid and Postpaid Plans

A key question for many users is whether they can switch between prepaid and postpaid mobile plans. The good news: Singapore supports both directions—and the process is seamless.

Porting from Prepaid to Postpaid

Ideal for users who want:

• Higher data allocations

• Monthly billing convenience

• Lifestyle perks like TADA promo codes, travel vouchers, and more

Porting from Postpaid to Prepaid

Perfect if you’re:

• Reducing expenses

• Needing flexible, commitment-free plans

• Managing a secondary number for ride-hailing app registration, deliveries, or business

How to Prepare for a Smooth Porting Experience

Before initiating a port-in request, follow this checklist:

• Check your contract end date (if on a postpaid plan)

• Back up your contacts and SMS, though most data is now cloud-synced

• Notify key apps (especially banking and ride-hailing apps) so you can re-login post-port

• Have your NRIC/FIN ready for verification

• Activate your Circles.Life SIM or eSIM before requesting the port

How Does Porting Impact the Apps You’re Using?

When you transfer your number to Circles.Life, most apps continue to function as normal. However, it’s smart to review how certain categories may be affected.

Ride-Hailing Apps

After a successful port, all major ride-hailing apps in Singapore will still work with your new Circles.Life service. These include:

• TADA – Budget-friendly with no commission fees, supports monthly promo codes

• Ryde – Offers carpool and taxi options

• Grab – High availability across the island

• Gojek – Known for competitive promos and fair pricing

• ComfortDelGro – Reliable service with a strong taxi network

Circles.Life plans often come with lifestyle perks, so be sure to take advantage of any ride credits or vouchers included.

OTT (Streaming) Apps

Streaming services like Netflix, Disney+, and YouTube Premium won’t be affected by number porting. You may be prompted to reverify your number if it’s tied to account security, but your subscriptions will remain active.

Gaming Apps

Game accounts tied to your email or third-party logins (e.g., Facebook, Apple ID, or Google) will be unaffected. If your number is used for verification or in-game purchases, update your profile with the new SIM once porting is complete.

Banking Apps and OTPs

Your mobile number is commonly used for:

• Two-factor authentication (2FA)

• Transaction alerts

• Account recovery

After porting, most banking and wallet apps will continue to send OTPs to your number. Still, you may be asked to reverify your identity or re-log into certain apps. Check your account settings and ensure your ported number is properly registered.

Chat and Calling Apps

WhatsApp, Telegram, and similar apps typically continue working post-port, since they're linked to your phone number. You may be prompted to reverify your number. Back up your chats before making the switch to ensure a seamless experience.
