Can't get setSmsEnabled to work

[Brian]

I have been trying to set the checkbox "Receive text messages on this phone" by calling setSmsEnabled() but it does not seem to be working.  Can anyone shed some light?

Here is my code:

AllSettings settings = objGV.getSettings(true);

Phone[] phones = settings.getPhones();

phone[0].setSmsEnabled(false);

Thanks,

Brian
