MMS and Internet problems - Three mobile AU

[Captain_coco265]

Hi,
I'm a new member here and new Imagio owner.

Anyway, I purchased my HTC imagio on ebay like most would and I put the Teya rom on it [Link] and everything seemed fine except for the MMS and internet.

I am going to be upfront and honest, I have no clue what to do so I submitted a ticket to my phone company (Three mobile AU) they gave me two links; one for internet and the other for mms.

I tried both of the guides and it still doesn't work.

I even put the default rom back on my device to see if it would work; it sadly did not make a difference.

What am I doing wrong here?

The only other information I can think of giving is my plan which is a $29 pre-paid cap - [Link]

Any helpful information about this problem is welcome
