I recall seeing several comments in the past where people have outlined which carrier porting combinations are easy and which take longer. Anyone happen to have this info stored in their brains? (e.g. Voda -> Voda, Telstra -> Optus, etc)
Would be great to know which paths take 30 mins and which take a whole day.
Thanks in advance.
I tried to find it for you but failed.
Easy way is to go to the website of the carrier you want to port to, then search the porting time, they will tell you how long it is to port a number from other carrier to theirs.
