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.
