In case you bought a prepaid SIM card before 17/12/2016 and you haven’t identified yourself yet upon that purchase, you’ll still have to do so. Don’t take the initiative yourself, please wait until we reach out to you to finalize identification. If we don’t contact you, this means you’ve already identified yourself. No further action is required.
Of course you have at all times the right to consult and update your data if need be.
