TMobile clarifies just when its 200MB of tablet data is truly free

T-Mobile's offer of 200MB in free monthly data for tablet owners seemed too good to be true, and to some extent it was -- a few customers have ended up with bills. However, the company has set the record straight with a Q&A post. To get completely free internet access, you'll need to own a fully paid-off device; opt for the carrier's financing and you'll have to tack on a $20 data plan if you aren't already a customer. Mentions of an additional $10 network access fee were a mistake, T-Mobile says. The gratis internet service does have some strings attached, then, but it really is possible to avoid charges if you're careful.
