An unlocked iPhone is an unlocked iPhone; right? Not exactly. There are different types of unlocking, with different consequences that the user has to deal with, and if buying an iPhone, you need to be aware of what you are getting.
There are factory unlocked (FU) iPhones, worldwide unlocked (WWU) iPhones, and chip unlocked iPhones. Each of them is different in some way from the other, and they each offer different levels of freedom. Let’s dive into the details.
Chip Unlocked iPhone
A chip unlocked iPhone is one that is locked to a mobile network or carrier, usually on contract. As a result, the full financial value of the phone has not been paid. Payment is usually on a monthly instalment and the network lock is a measure by the carrier to keep the user from making away without completing the payment. A chip unlock bypasses the network lock by using a small, special physical component called a chip.
So, a chip unlocked Apple iPhone is one that uses a chip inserted in the device to bypass the network lock. The disadvantage is that you can only use one network per chip.
So, if you are currently using a chip to use a Vodacom SIM card in your iPhone and want to use another SIM in it, you will need to buy another chip.
WorldWide Unlocked iPhone
World wide unlocking (WWU) is done via software and enables you to use any SIM card with the device. You can change SIMs as you please and use them without any worries or inconveniences, so long as the phone is compatible with the mobile network. ,
Is there any caveat? Sure: if you factory reset or wipe that phone, the original carrier lock will come back and you will be unable to use it with any other carrier except the one it was originally locked to. On other words, you have to go through the software unlocking again.
Factory Unlocked iPhone
A dactory unlocked (FU) Apple iPhone is one that is sold free of a lock to any mobile carrier. This is what you should be wanting. It is sold by Apple and at independent stores in the USA, Canada, UK, South Africa, Australia, and many other countries around the world. It offers complete freedom, as you can insert any SIM card from a compatible network at anytime and use at will.
In summary, a chip unlock requires a physical chip for the iPhone to be usable with another network’s SIM. A WWU is carried out via software and requires no physical chip. A factory unlock is the definition of true freedom and comes with no restrictions.
When shopping for an unlocked iPhone, do not forget to ask what kind of unlocking it is.
