MMS After deBrand ??

I have a C902 that thanks to the people here, helped me out with de-branding the unit.

As a result of the de-brand it has taken all apps with it.

Today I was sent an audio clip from someone else's mobile. When I go to play the sent message,the C902 responds with: "Setting for MMS is missing..." and asks me if it can connect to the internet, presumably to download the required app.

As I don't have a data plan I can't install the app via the phone.

What do I need to do to get around this hurdle?

Fritzables.

But it still tries to connect to the internet - is there a way I can manually install the app??
