[Q] Sprint galaxy s4 no current service trying to unlock sim..possible?
I have a Galaxy S4 through Sprint. It was a replacement phone to another phone but never technically activated. I rooted phone and put a straight talk sim in, says invalid sim. I have tried many apps, places to buy codes, no one can get this phone to work. Is it because it doesnt have prior service? (Didnt think that would matter) Or can someone please tell me how I can make this phone work? Thank you
Btw I now have no active working phone, but my number is on the straight talk sim in the galaxy phone. I desperately need it on. It was transferred earlier from another phone and now im in a pickle.
