Why my porting request has been cancelled?

Portability can be cancelled for a number of reasons.
For example, if the line you are trying to port to Onoff is inactive with the current operator, or if a portability is already in progress.

Also, as a security measure, when a portability request is made in our application, an SMS is sent to the line, to be answered with a secret code.
If you don't reply to this SMS from the line to be ported, then the portability request will be automatically cancelled and you'll have to start again.
