S What is the difference between an unlocking of mobile phones and a factory for mobile phone unlocking?

What is the difference S between an unlocked phone and a mobile phone factory unlocked? And what a mobile phone debranded?

Unlocked means not linked in a network, like AT & T or TMobile. You can get an unlock code from a GSM phone in various ways, that actually provide TMobile the code is I've had the phone long enough. Factory unlocked only that, the phone was not locked to one carrier when sold. Debranded is the elimination of all special screens, menus, and software that ties a phone to a particular company. This can also mean not having a telephone company name on the outside of the phone also. You may lose some specific functionality of the phone network of its kind. If all you do is make calls and text occasionally, never mind. MMS, internet, wifi, such things may not work correctly.
