Can a DCT4 sim card work in a DCT3 phone?

I have a Fido phone model 3390. I used crux's unlocker, keyed in the code
and got the 'sim not restricted' message with the check mark. I then tried
my card from my Rogers 3220B phone.

The Fido phone is listed as DCT3 and the Rogers is DCT4.
The Fido phone gives the message "SIM card not accepted".

The unlock seemed to work based on the screen code (a wrong code gives an
error message). Any chance there is a difference in the sim cards?

well, I found another program that unlocked 1 and 2. With Lock#2 removed, it
took my Rogres card ok. Now I am trying to figure out the details for the
3220B phone.

I seem to be my own tech support here...

This is how I unlocked the new Rogers 3220B phone. Now I need to figure out
how to turn off those flashing lights as I talk.
