Doesn't sleep, can always keep devices "in the pipe"
T-Mobile doesn't charge overages
Cons: Obviously it will suck if you run out of the 10GB max plan. Don't know how it compares to Sonic. If you're not in 4G territory don't expect fast speed.
Summary: I couldn't make heads or tails out of why the Sonic version cost more, but supposedly it's faster. We're getting 5 to 6 mbps down and 1.5 up consistently. Honestly...that's faster than many homes or offices I've been in. It's a great little device that has put broadband in our industrial office space where neither DSL or cable were available. Haven't had it long, but so far, so gooood.
