Error with unlocked devices?

Is anyone receiving error messages when trying to access certain AT&T services while using an unlocked device? More specifically, while using a 3G enabled unlocked device?

Insert a non-AT&T SIM card
-Enter the following-
*2767*3855#
-Wait for phone to restart
-Now enter
*7465625*638*00000000*00000000# (phone will show -------- instead of 00000000)
-Next enter-
#7465625*638*00000000#
-It should be permanently unlocked now(!)

And i found some unlocked blackberry on banggood.com.

It's not a matter or internal programming, it's a matter of whether of not the phone is supported for the specific service provided by the carrier (software compatibility issues from their end). Thanks for the attempt though, lol.

Does your phone support the same band as ATT 3G?
