To port a number from Singapore across to Delacon, you must ensure you have another phone number from which you can make and receive calls. The current number you want to port across will no longer be able to make and receive calls during the porting process.
The costs for porting your client's number to Delacon will be as following:
$100 setup port fee
+ number fee
+ minute fee
An alternative would be to set up a VOIP system with Delacon where your inbound number will be forwarded to a VOIP softphone so that you can use Delacon for inbound and outbound calls.
