Straighttalk appears to be CDMA only in my area and to confuse you, this phone has WDCMA which is something else.
The 6350 is not very special and there's little reason to keep it.
I plan on leaving ATT for Straighttalk, unlocking my 6350 Nokia phone and using it on their system. Are most sim cards interchangeable? Will my idea work?
Thanks for your help.
