We currently provide our mobile services for free, but please be aware that your carrier's normal rates and fees, such as text messaging and data charges, will still apply.
In the event you change or deactivate your mobile telephone number, you will update your account information on Facebook within 48 hours to ensure that your messages are not sent to the person who acquires your old number.
You provide consent and all rights necessary to enable users to sync (including through an application) their devices with any information that is visible to them on Facebook.
