How do I enable call forwarding on AT&T sim with Verizon TP2?
 

I've searched the forum and the web and have been unable to find a solution to my problem

I have a Verizon TP2 with the Verizon 6.5 ROM and an unlocked sim. Voice and sms works great but I can't figure out how to enable call forwarding with the AT&T sim. When I follow the instruction on the AT&T site using *21*... I get a "Command not supported" on my phone. When I go to the Phone Settings "GSM.UMTS Services" there is no option for call forwarding. I can forward just fine with my old AT&T phone. Does anyone have the fix? Please help.

Alright, I have installed the Show Hidden Phone Settings.cab from this post and now call Call Forwarding shows up but I get a "Network Error" "Cannot read settings from the network. Try viewing settings later, or disconnect data connection and try again." All of the other options work except this one. I do not have any data configured with AT&T and all of the settings are the Verizon ones. Do you think this could be the issue? Does anyone have call forwarding working on AT&T with a Verizon TP2?
