So a little while ago, I was with Ntelos in terms of phone service, but since they were dying out and no longer having service in my state, which is Virginia, I had to switch companies and decided to go to Metro PCS. The biggest problem was that back then, they had said that they wouldn't take in my phone, so I had settled with a free (and shitty) Samsung Galaxy Core Prime for a few months. About a week ago, I heard about the ability to unlock phones and switch carriers, and really wanted to go back to my S3 but found it difficult for me to do since the old carrier for this phone, Ntelos, no longer operates in my area. I was wondering if there happened to be ANY way I can unlock or flash my S3 so I may be able to put service on it again. Thank you.
