Unlocked T-mobile Pebl on Rogers?

I have an Unlocked t-mobile pebl.
It works fine on the Rogers network except there is no Web or MMS.

I know I have to change the settings. And I have been able to find the correct info to put in but I cannot figure out where exactly to input the information! I have done some extensive research and still have had no luck!

Any help would be fantastic!

Thanks so much!
This is a t-mobile phone that is unlocked.
Not a Rogers phone. They do not support handsets that are not their own.
