An SMS message that exceeds 160 characters is considered to be Long SMS.
When you exceed the SMS character limit, you will be charged for each additional message.
e.g. if your SMS is 2 messages long and your SMS rate is 7p / 7c, then you will be charged 14p / 14c per long SMS.
The 160-character limit on SMS is due to SMS technology itself and is not a limit set by Phorest.
