Hi there,
You may contact to your service provider
Samsung SGH-E690 Unlock Code to get your code for unlocking your phone. I suggest to visit
Samsung Unlock Code site, they will provide you an accurate code with easy to follow instructions on how to unlock your phone. Once your phone is unlock, it will work with any network worldwide. No need to stick with one network.
Hope this is helpful.
Thanks.
