I think there is another topic about this, but it might be dead.
I've got a 9800, running 6.0.0.706 with Airtel, India.
Just noticed the send PIN messages option wasn't there, so I pulled the battery, and as soon as my phone booted, I opened the messages application and 'lo and behold! It was there!
I exited the application and opened it after a minute and two, and it was gone again!
I tried this a few times, and I've noticed the option disappears about 20 seconds after the phone boots up. Does anyone also have the same problem?
However, please note, I can send PIN messages, I clicked the option while it was there, and managed to send a PIN message to a friend, and the tick mark along with the 'D' appeared.

Any help would be appreciated!

That was also an issue with the same version OS on a 9650. Try a hybrid or downgrade/upgrade.
