    I think it's two bytes per character. One byte allows 256 different characters, and there are more than that available (consider that you can send a message in languages such as Japanese or Arabic if you wish).

    Yes, 8 bits = 1 byte. For any ASCII character you need an 8-bit combination, which effectively makes every character a byte.

    Bah, you guys are too quick. I wrote something, realised it was wrong and deleted it, then edited it. That's how my post snuck in above without you seeing it :p

    This is true for non English (or Latin based) languages. However, for regular ASCII, it holds that 1 char = 1 byte.

    Well, I guess it depends on whether the phone/network is clever enough to dynamically switch encoding based on what's been entered, or whether it'll do everything in "extended" (Unicode?) format.

    Ah, and this would apply for a regular text message, yes?

    Goddammit you snuck in again :p

    Anyway, on my old cellphone I think I remember it saying the number of bytes in a message as I wrote it. And I think, I think... it added one byte with every character I entered. Not certain though :eek:

    Unnecessary anecdote: I used to have a handset which, when set to use English, used up several characters in the character count when using letters like ç, but when set to French ç only equalled one letter in the character count.

    (this is really a tangent post)

    ^ says how many letters a message can be, but it doesn't say how much data is sent in total (including metadata). This mightn't be relevant to the question, since each message sent is a flat rate.

    While I couldn't find actual any info on what data is sent alongside the SMS digest, this page shows what data is stored with a single tweet.

    Routing and metadata are not counted, but depending if you bust character count, your message could cost you extra as there is such a thing as concatenated SMS, which is a set of SMS messages that each represent a segment of the total message. Each segment could be charged as a seperate SMS since that is what it is. If your message requires segmentation for a concatenated SMS, your character count will be lower as an additional header is inserted right into the user data portion (7 bytes for 7 bit ASCII encoded messages, 8 bytes for 8-bit or 16 bit encoded messages.

    If you really want to dwelve into the deep layers of GSM/SS7 signaling and message headers, there's always this page :

    http://services.eng.uts.edu.au/userpages/kumbes/public_html/ra/sms/#Service Elements

    Again, since this is the Internet and we have search services, I'm quite surprised it took over 10 posts before someone just bothered to look it up. Was this question even worthy of a thread ?

    ************************** comes to mind... I guess that's the new generation of "Internet users", they just browse forums and facebook...
