Thanks @OldGreg_Sprint. Looks like my device is unlocked. I am traveling internationally - I was able to insert non sprint sim and it is working. However i had to manually add the APN Profile to access internet.
Hello. I have same problem. After oreo update my phone stops working with my sim card. I try to update PRL and Profile but it says "authentication error try again later". I'm also tried insert old Sprint sim but it seems expired or something, and same problem with activation. Meybe somebody can help me? I'll be very appreciated
Hey Danpeter. We can help out with that but we'll need some information from you via PM. I'll be sending one along your way shortly so we can help out.
Hello friends. After two weeks my phone locked again. I'm not understand why. What to do next? PLEASE HELP, I'm really tired...
Howdy Danpeter, that strange. Normally once a phone is unlocked, it stays unlock. Well unless the SPrint sim card was re-entered in to the phone. I'm going to send you a PM so I can gather some more info.
After your phone was unlocked did you restart it and then dial ## SCRTN# with the Sprint SIM in it?
Okay. I'll need to resend an unlock code. What's the IMEI of your phone?
