Maybe research all the major carriers' character limit and use the lowest one as the maximum for the outgoing messages.

The reason for that is the maximum length of a SMS message payload is 160 7-bit characters. Longer messages are combined into multiple payload deliveries, reassembled by the phone. Two messages together may send up to 306 7-bit characters, since there is a 40-bit header if you split up the message.
