Yes, my first bill for just a single line with the 450 minute plan and the $5 text plan was about $200. They made my bill drop date be a few days before I got the phone, so the first bill was almost 2 months of charges. If you have the 149.99 plan, it could be as much as $300 + the activation fees + the taxes, depending on the dates they use. The first bill could be close to $400. I know AT&T sent me a little warning sample bill a few weeks after I got the phone, with a special warning in red text that the first bill could be unexpectedly high like that, lol.
