Number Porting

Number porting is available for Singapore only. 

Porting Process (Step-by-Step)

Step 1: Submit Documents to Nautilus

Send the signed LOA and your latest telco bill to your Nautilus account manager or support contact.

Step 2: Verification & Pre-check

Nautilus will:

• Verify submitted documents

• Check number eligibility

• Submit a porting request to the Singapore central porting authority

Step 3: Porting Date Confirmation

Once accepted, we will:

• Receive a target porting date (usually within 5–10 working days)

• Notify you of the exact cutover time

Note: Porting can only be done on weekdays (Mon–Fri), excluding public holidays.

Step 4: Testing & Cutover

On the porting day:

• Calls to the ported number will begin routing through Nautilus

• Our team will test to ensure routing is complete and functional

• You should remove the number from your old telco systems (if applicable)
