Unfortunately, it's not just a handset or modem problem. Thanks to our programming modification, we can vary the number of characters. We've tested sending above and below 160 to different handsets. The problem appears to be carrier-related. Each carrier appears to have a different protocol as to how they transfer an SMTP email to SMS text message. But, still not sure what's going on.
