France publishes consumer guides on mobile number portability and unknown bank debits

In France, a guide explains how customers can switch mobile operators while keeping their existing phone number. The process relies on number portability, where the new carrier obtains the subscriber’s RIO code (by dialing 3179) and handles the termination of the old contract, ensuring a brief service interruption but no loss of the number. The guide outlines steps for moving from operators such as SFR, Orange, Bouygues or Free, warns about existing commitments, and clarifies what portability does not cover.

Another French advisory piece advises consumers who spot an unfamiliar bank debit. Before filing an opposition, users should verify the transaction’s origin by checking receipts, email confirmations, and discussing with family members who might have used the card. The article notes that delays between purchase and posting are normal, and that the account holder remains liable for authorized debits. If fraud is confirmed, the guide differentiates between opposition (preventing a charge), contestation (after a charge), and revocation, and explains the appropriate timing for each action.
