activating a Straight Talk phone for a customer? Will I get in trouble for this?

So these two girls came in from Australia and bought Straight Talk phones so that way they didn't have to pay a ridiculous roaming fee. I set them up for them because they politely asked. It was a new number new device activation. I did it through the computer but it said to call. So I did 40 minutes later I had working phones for them. And they were saying I was basically the nicest person in the universe.
