Can an option be added to send use concatenated SMS (also known as multipart or segmented SMS, or "long SMS).
This will allow messages longer than 160 7 bit characters. eg. first 153 characters in SMS1, then the next 153 characters in SMS2 etc as a multipart SMS.
I know that this will mean more SMS messages sent, but will allow users to receive full notification with most modern phones supporting this standard, the user will see a single long message.

Maybe GHL could give the user the option to turn on long messages if they require?
maybe in 2015.
