Transferring or porting your number can take anywhere from 10 minutes to 24 hours. Porting multiple lines and porting landlines can take up to 10 days. It all depends on which carrier you are switching from and to.
Porting your number means bringing your current working service number to a new carrier when you switch services. Your new carrier will do this for you!
Do not disconnect your number you are wishing to port because the port process will do this automatically. If you disconnect your number with a working service before you port, it will be really hard to get that number back.
Most carriers manage the number porting as part of their online activation process when you receive your new phone and simcard - or they will handle it in the store itself.
