Samsung does not ask for the unlock code

What to do when your Samsung doesn’t ask for the unlock code?

First thing, DO NOT worry

There is one thing you can try when your Samsung doesn’t ask for the unlocking code. Some require you to already have the unlocking code but there are some that do not require one.

Basically, your Samsung will inform you that it’s network locked, but will not allow you to insert a code to unlock it.

If your phone does not ask for “SIM Network Unlock Pin” then you can go to the dial screen and press

  • #7465625*638*#

Congratulations! Your Samsung now asks for the unlock code.

If your Samsung still doesn’t ask for the unlock code you can check out another article from our Help Center that will guide you through more troubleshooting steps, but for those, you are required to already have the unlock code generated.

Exception!

Please note that there is also the possibility when your phone can only be unlocked through the Device Unlock app specific to T-Mobile USA and Metro PCS USA.

In this case, your Samsung will not prompt you for any unlocking code because there is no designated field in which a code can be inserted.

  • Hi, I have a sprint s9+ it’s eligible for unlocking, but Sprint won’t do it. I have paid once before to have it unlocked and it said that it was, but now all it says is invalid Sim card and Sim card unreadable. It doesn’t ask me for an unlock code and the previous attemptee had me download their unlocking app. I tried ordering from you guys using multiple browsers and it refused to let me submit my information.

  • Ok . I have tried everything to get my galaxy s6 to unlock from Verizon. Not getting code prompt, did hard reset and tried the method here. When I tried it here with verizon sim it says not on network, when I tried with tmoble it says in valid mmei. Any way to unlock this phone for my daughter? It is my old phone that has been paid for.

  • Hello, I have a Samsung Galaxy S9 Plus which was purchased and activated through AT&T. I received an eight digit unlock code from AT&T through E-Mail and the phone showed unlock successful when entered. I tried Sprint and Verizon sim cards and neither would work. AT&T says according to their system the phone shows to be unlocked and there is nothing more they can do. Is the phone not compatible with other carriers since it was purchased from AT&T? Any information you can provide would be greatly appreciated! Thanks in advance! -Eddie

  • Please help me. I have a Samsung galaxy s6 and I have an activated sin card for my ZTE haven. The company I go through say the sin should work but it doesn’t. Without the sin my Samsung says “no sim card inserted” when I insert the sim card and try to use this unlock code or even make a call it says cellular network unavailable. Can you help? I bought the Samsung from a pawn shop that is owned by a cop who assured me that wasn’t stolen but it may be locked. Can you help me?

  • I have a Samsung Galaxy S5(Sprint), before leaving to Europe, I called Sprint and they’ve provided me with a pin code(SIM network unlock pin) in order for me to be able to use this phone is Europe. The problem is, once I insert a SIM card, my phone doesn’t ask for a pin. The pop up doesn’t appear at all. Up on the notification bar it’s showing a “invalid sim card” message. How can this be fixed?

  • My sprint galaxy s8 says invalid sim card when I put in my mobile one and dialing the code does not do anything.
    Please help.

    • Hi Aaron, your phone might still be locked to Sprint. Call your carrier to verify this. If you’re no longer locked to your carrier, ask if they can unlock it for you, if they can’t get your unlock code go to this page https://www.unlockunit.com/unlock-samsung to check if your phone is eligible.

    • Hi Jason,

      We found this tutorial.

      Another great tool you can try is the AT&T Troubleshoot & Resolve, which provides additional simple steps you can apply to resolve network issues. Once there, select your phone’s make and model > Service/Network issues > Phone calls/Internet.
