I have a sprint samsung galaxy s3 and I was gonna get it flashed to another carrier, I bought the phone off craigs list and dnt have the account holders info. The other carrier told me to get the msl, so I called sprint and they wouldn't give it to me, I've tried every thing (mymsl, terminal emmulator) and nothing worked. I know the phone has a clean esn and all just dnt understand why I can't. Get the msl. I have the imei and meid if anyone could help.
Imei: 990003351239690
Meid: 256691486901194345
