Right, as long as it does not steal the service, & it doesn't legally you are safe.

If a PAM plan didnt require an exsisting connction (and it does) you are made to use a HOW and thats it.

PAM offers no data in itself only the means to use the existing service.
By compliance, you are not restricted to use an alternate service if you have means (legally).

For example if you have a phone plan that restricts long distance call but you use skype to do this over the carriers data, you can legally make this call. You are using a legal alternative method.
