Couldn't pass up the 29.99 deal to add a line. I'll be paying $40 extra per month, and then only $10 extra per month when I drop the data plan on my original line. Anyways... I read the terms very carefully. You have to stay with the service on the new line for 6 months so you don't get charged by wirefly too. Seems easy enough. My question is, can I do whatever I want to my original line (change phones, etc.) without it affecting my wirefly thing? I used wirefly to get a family plan with a new line, so it shouldn't be affected by messing with my original line, but I just want to make sure.
