1. Can I transfer my existing number to heya?
Yes. To transfer your existing number, it must be an active Postpaid mobile line with no outstanding payments and registered under your NRIC/FIN with your telco. Your request to port-out from your existing telco must be submitted at least 7 days before your next billing cycle.
We are unable to support port-ins from Singtel plans at the moment
4. I've opted to port in my number. When can I start using my heya?
Transferring your number to heya will take up to 3 days. You can use your heya SIM after successful port in.
