Unlock a Sony Ericsson mobile locked to the 3 (Hutchison) network

I recently acquired a Sonya Ericson C903 handset, which was locked to the now defunct Three network (formerly Hutchison Australia) which was recently acquired by Vodafone.

Vodafone has a free service that provides the relevant unlocking code when given the IMEI number of the phone;


They will also provide the unlocking procedure as per the following document;

Sony Ericsson Unlocking Procedures

Now the problem is you need a working 3 network SIM, where do you get this from?

For free, you can go into any Vodafone store and ask for a ‘blank 3 SIM’, which you can use to allow you to follow the above Unlocking Procedure in store.

It is that easy.

Thanks to Vodafone for their free support helping unlock my phone.

Unlock the Nokia 6300 for under $10 with the iSIM

Here’s a quick post on a tested method to unlock a Nokia 6300. Well, not quite unlock a Nokia 6300 but trick the phone into thinking your SIM is of compatible carrier. I purchased the iSIM from eBay for $10 including shipping to Australia. When searching on eBay, search for “unlock 6300” and arrange by lowest price first.

The iSIM is a IC that goes in-between your phone and SIM card. The only drawback with this method is having to cut a 5mm by 5mm slot into your SIM card to allow the chip to sit flush (see below picture)

I successfully tested the iSIM with a locked Nokia 6300 to Vodafone, with an Optus SIM card.
