Help Phone wont register on EE

[Jasondroid]

I have just broken my Samsung Galaxay S4 and whilst I'm getting it repaired I want to use my old HTC Desire S with my current EE sim.

I have taken my EE micro sim out of my S4, fixed it into the adapter card that came with the sim to make it normal sim size and have pushed it into my Desire S.

I am (fairly) sure that my Desire S is unlocked as it was originally on O2 I think. However, the EE network is not recognised as soon as the phone is turned on, but it doesn't give me a warning that the sim is not present. When I search for new networks the phone finds all of the networks fine so I select EE and I get a message telling me "your sim card does not allow connection to this network"..

I could have sworn the phone was unlocked. Is it not?

Or is it that EE being a newish network has trouble connecting to the older phones.

All network settings are factory default.

Please help.

I don't know how they do it there, but in the US you can bring the phone into the store and ask them to do an "equipment swap". They'll give you a working SIM for the phone. (For free usually - SIMs are worth a few pennies.)
