Well, I tried using the stock message app and Go SMS Pro app, I also checked if the number for SMS services is ok, and it is. I tried to uninstall Go SMS but I still wasn't able to send SMS longer than 160 characters. It is possible to split longer messages, but it's quite uncomfortable for the recipient.
Anyway I'll try to figure it out and let you know if I find something.
