Basically I had set up FB on my phone with my other emails. I also enabled Facebook chat on it as well. However, I got a message from someone both on the Facebook app as well as on the "Messaging/Online Threads" section. The thing is that I don't have texting from my calling number anymore and it looks like it only got sent to my profile's message inbox on FB and on the Messaging Online Threads.

Am I going to be charged or I can still send a message Since before replying it says "Chat on Facebook"??? Thanks

FB Chat and SMS are handled in the same interface on the phone, but FB messages are NOT the same as SMS text messaging. You will not be billed for anything that is chatting over FB Chat.

No Facebook is based on your internet connection and not your sms service.

That's what make WP so special, you receive certain messages in one tab even though it is from different interfaces.

Thank God. I accidentally texted my niece's mobile in India and I'm in US
