I'm going to be buying the Thunderbolt soon and I was wondering if it costs extra for the 4g hotspot service. I was unable to find if there was a promotional deal or if it was 30 dollars a month. Any clear answers are appreciated.
The hotspot is free for all Thunderbolt owners until ~May 15th. At that time, you'll be able to subscribe to it if you still want it. For those that don't, there's nothing to cancel.
