Hello,

I am trying to find a good replacement phone for use with an At&t sim card. This is the new At&t merged with cingular.

I want to know if the At&t sim will work in an treo 650 cingular phone...
 
Once you unlock the Treo 650, you will be able to swap with other GSM network. I suggest you can approach Simpleunlocking.com and specify the country,locked network of phone.Based on the availability you can get the permanent unlock service along with free instructions.
