What Is Number Portability?

A Guaranteed Right
Since 2003, any mobile subscriber can keep their number when switching operators. This measure aims to facilitate competition and free consumers from being "locked in" with their historical operator.
The Step-by-Step Procedure
Step 1: Obtain Your RIO
The RIO (Operator Identity Statement) is the code that identifies your line. It's essential for portability. To get it, call 3179 from your mobile. It's free and available 24/7.
Step 2: Subscribe with the New Operator
When subscribing to your new plan, indicate that you want to keep your number and provide your RIO. The new operator then handles the entire process.
Step 3: Wait for Portability
You receive your new SIM card. Effective portability generally occurs within 3 business days. You're notified of the exact date and time by SMS.
Step 4: Temporary Interruption
On portability day, your old line is cut off and your new SIM activates with your usual number. The interruption lasts a few hours maximum, often less.
Points of Attention
Automatic Termination
By requesting portability, you automatically trigger termination with your old operator. You have no action to take with them.
Termination Fees
If you're committed, termination fees may apply according to your contract. Check your conditions before proceeding.
Final Bill
Your old operator will send you a final bill for the elapsed period. It may include any termination fees.
Services Linked to the Number
Some services are linked to your number: bank authentication by SMS, account recovery, etc. They will continue to work normally after portability.
Special Cases
Portability with Ongoing Commitment
You can request portability even if you're still committed. You'll simply pay the termination fees provided in the contract.
Portability of a Professional Number
The procedure is the same, but make sure you have company authorization if the plan is in your employer's name.
Portability to a Prepaid Plan
It's possible but less common. Check that the prepaid plan operator accepts incoming portability.
What the Law Says
Portability must be completed within a maximum of 3 business days from the request. If this deadline is not met, you can claim compensation (3 EUR per day of delay beyond the first day).
Conclusion
Number portability is a simple process that shouldn't deter you from switching operators. With a few clicks and your RIO, your new operator takes care of everything. You keep your number, your contacts see no difference.
