How can i unlock my qlink sim card

[Mkatz1983]

I put my sim card into another compatible phone and it says my sim card is locked

Welcome to Android Central! If the SIM card was locked with a PIN, you need to remember your PIN (if you set it) or ask the original owner of the SIM card what the PIN is. If that's not possible, then contact Q Link for a replacement.

Are you sure it's not the phone that's locked to a different carrier?

It probably told you that the SIM was incompatible, or something like that. Because the phone is SIM-locked to a different carrier than the one you were using. (QLink uses TMobile's network, so that's the carrier you were on, and it's the carrier in the SIM card.) And it would be the carrier that locked the other phone that would have to give you the unlock code - if you had a plan with them, and the phone was paid off. (If you got the phone from someone else, that person has to request the unlock code.)
