The most secure way to unlock a router is to contact the original network provider. Most carriers have specific policies for unlocking devices once a contract has been fulfilled or a specific period has passed. They can provide an official unlock code or update the device's status remotely, which ensures the warranty remains intact and the device continues to receive official security updates.
