Ok Im new to this but from the message listed you cant do anything with a nokia 5610 correct? The situation is like this a friends daughter found a phone and its t mobile, we dont even have tmobile in the area in which i live so therefore i dont have any use for it unless i can change it to at&t...it takes my sim lets me unlock my sim card but then ask for a restriction code....which i dont know what that is but its a really nice phone and id like to use it if possible but if not i guess ill ebay it or something. Thanks for any info you can give me. Loonky
THERE ARE NO CODES FOR THESE PHONE MODELS, THE ONLY WAY IS TO CONTACT YOUR SERVICE PROVIDER, BUT IT WILL COST.
