Do you want to cancel your subscription with your mobile phone operator but you don't know how? In France, nothing could be simpler. You just need to retrieve the RIO code of your number by dialing 3179.
Then, all you have to do is indicate this RIO code when registering with your new operator, you do not have to take any steps to terminate with your old operator , it will be done automatically.
You may still have to pay the termination fees with your former operator if you were still engaged (more details on termination fees, click here ).
