Yes, if you call the Cricket carrier that is selling this phone, you can get the unlock code (SIM Network unlock PIN), but you must meet the requirements that the network provider requires. If you do not get unlocked in this way, you can always buy the unlocking code on our website, in a few hours your phone will be unlocked forever, by code, without losing the manufacturer's warranty or any information.
Of course, our unlock method to unlock the Samsung SM-J727AZ is by code, it's the same code that Cricket provides you.

3. - The device will prompt: “Network lock”, Now enter the code and press OK.
4. - Your phone will indicate: "The operation was successful", becoming permanently unlocked.
