So you have a better battery time than mine!
And if this is some CDMA phone, there is never an unlock. It confounds folk but for those you have your new carrier move the phone to their system. That's not unlocking is it?
http://www.howardforums.com/showthread.php/1785087-OFFICIAL-Samsung-S380C-CDMA finds it is CDMA and my advice is to stop asking for unlocks. CDMA is different and if you keep asking, folk can get tired and you may get upset.
I am a low income person because of disability. I bought a straight talk phone to activate only when I travel. I just qualified for a free phone. They sent me a phone that is so bad it only holds a charge for 8 hours. They will transfer the service to any phone. I took the straight talk phone to Walmart and they were very rude and said "We don't unlock phones here". When I called straight talk, they hung up on me the first time. I called back and they told me that since I hadn't used the phone continuously for a yeàr, they would not unlock it. If anyone knows how to unlock a Samsung S380C, please let me know.
