*HELP* :( How to SIM unlock?

[Johnna G]

I have a LG Tribute HD (Android 6.0.1) that operates with a specific SIM card. I misplaced the original SIM. How do I unlock the SIM slot to work with other cards? I spoke to Sprint, but they required the previous account holders information which is still linked to the phone. Since I bought my phone used I don't have access to that information and can't get it. Is there any other way?

That previous account holder information would be needed in order to (arguably, legally) complete the process. For all the rep knows you found the device on the street and are trying to use it, while someone else is looking for their phone.

I don't know how you made the transaction but your only recourse is to deal with the seller
