Blue are sent as an iMessage. Green as an SMS message.

And who decides when the msg is an imsg and when its an sms msg?
Also what is the difference between the two?

iMessage are always free. Used when you message another Apple device.
SMS will use up some of your text allowance from your carrier (most these days are unlimited so no biggie).
Occasional when texting an Apple device it will switch to SMS, not sure why.

Will iMessage work only when internet is available?

You need the internet or a mobile mast to be working. Doesn't matter which.

What is a "mast"?

What is a "mast"?

In range of a cell tower. So if you get phone coverage it will work. If you have no wifi or service it won't.

So, if there is no internet connection but there is a phone coverage, there is no "blue" msgs but only "green" ones... is that correct?
