Possibly. On a 4.1.6 BES, the Device-Only Items/Allow SMS policy item is defined as: Specify whether the BlackBerry device permits sending Short Message Service (SMS) messages (text messaging).
Set this rule to False to hide text messaging functionality on the BlackBerry device.
Note: To block incoming text, or SMS, messages, set the Firewall Block Incoming Messages IT policy rule in the Security policy group.
If you do not set this rule, a default value of True will be used.
This rule applies only to Java-based BlackBerry devices version 3.6.0 and higher.
I have highlighted several key words there.
If your BES Admin has set this item to FALSE, but has NOT set the Firewall Block Incoming Messages (with SMS checked) then the result would be that you can RECEIVE and not SEND SMS messages. HOWEVER
From the error that you are having, I think this is a carrier and not IT Policy issue. I would recommend you call your network...
