My experience ...I did online with NRIC verified online, collected SIM Cards from Service CenterInterested to know experience for Giga port over to Simba(Senior) too.
Heard some failed porting experience , but I am wondering if the porting failure can be minimized by doing it in person at the service outlets (instead of doing online)? This is because the service rep. tends to do some checking (eg: check the port-in number validity and details such as account holder's name and compare against NRIC), so as to approve/finalize the porting request.
07.00am - started port-in process for 2 mobiles from Singtel to SIMBA
11.30am - collected SIMs
11.05pm - Singtel cut me off
01.11am - port-in successful!
Very fast!!
... within 24 hours!
