If your mobile phone has been purchased second hand it might be a little more difficult to unlock.
Some mobile networks will still do it for you, but others, for example, Vodafone, can request that the unlock is put through by the previous owner who originally had the contract.
If you do have any issues, consider having aGeek in Chesterfield unlock your mobile phone.
Please note: If your current network cannot give you a price for an unlock code, it may mean that it isn’t possible to unlock your phone with a code. If this is the case, do not try buying a code anywhere else. They may even charge you only to come back and tell you that it isn’t possible to unlock your mobile phone. You could try unlocking the phone using a cable instead.
2. If approved, use the unlock code
If and when your network comes back to you and confirms that your phone unlock has been processed, you may need to type a code into the phone to unlock it.
This is dependent on the type of handset you have – the network will supply you with specific instructions. With models such as iPhone, you only need to follow the on-screen instructions for using a different Sim card once it has been inserted. (This can involve connecting it to iTunes through a computer or laptop).
A word of warning with iPhones:
If you have an iPhone that is jailbroken, for the official unlock to work, you need to first remove the jailbreak and all of the associated applications from your iPhone. If not, you won’t be able to unlock the iPhone this way.
