Is there a manual way to put in MMS and internet settings?

[krnchonnom]

Iam trying to use my phone for ntelos. But I cannot find a cab file for it nor has anyone told me how i can pull it off from the original phone.
I have the original phone and another phones that i want to use.
Can anyone tell me how I can manually put in the settings?
