SMS limit is hardcoded at 460 but should be changeable somewhere
Twillio (and probably other sms providers) allows SMS messages up to 1600 characters, but Civi has the limit hardcoded at 460. I've verified that by simply going to CRM/SMS/Provider.php and changing MAX_SMS_CHAR from 460 to 1600 the system now accepts (and sends) messages up to 1600 characters. It seems logical that the character limit should able to be adjusted and stored somewhere rather than set as a static value in the code. We are currently using the larger limit, and would really like to see this implemented asap so that we can stop manually updating the code each time we update civi.
