Q: How can you tell your iPhone 5s has been unlocked?

Is there anyway to tell from the Settings menu on the iPhone or from a menu in iTunes that the phone has been unlocked. My wireless carrier has allowed me to unlock my phone because I will be spending an extended period of time in another country. Leaving in a few weeks. They have sent some kind of notification and bit of software to the Apple server. According to the instructions, this unlock instruction will be loaded on my phone next time I sync on iTunes.  But I won't be able to tell if the unlocking has been successful until I arrive in this other country and put another SIM card in the phone. So my question: is there a menu on the iPhone or in iTunes that provides any indication that the phone has been successfully unlocked?
