7 Best SIM Unlockers for iPhone/Android Carrier Unlock

Are you ready to switch cell phone service carriers? If so, you’ll first need to know what the best sim network unlocker is for you.

What Is SIM Unlocker?

While it is possible to unlock a phone through your carrier, each carrier has its own set of strict standards that must be met before they will unlock your phone.

If you don’t meet the unlock criteria for your current provider, there are paid third-party services – SIM Unlocker that can help.

Note: SIM Unlockers can only free your phone from carrier lock when its blacklist status is Clean. None of them work for you if your phone is blacklisted (reported as stolen or lost).

So, before using any of the following SIM Unlockers, you need to check the blacklist status of your phone with its IMEI. The only way to check is to use an IMEI checker.

However, too many IMEI checkers offer fake or inaccurate information, so you’d better choose a trustworthy one. We recommend WipeLock IMEI Checker, which provides a 100% accurate report.
