I put in my T-Mobile SIM card with unlimited data plan from my phone and it just worked, connected to 4G, no setting changes needed. I haven't checked if it's pulling from the unlimited data pool or the modem pool, this will show up in my T-Mobile account in a day or two. Speedtest.net only showed a drop of about 10Mbps, but opening webpages on my computer loads just as fast as usual. With the SIM card in my phone I usually get 40-50Mbps, so the slow results on the modem could be due to the small antenna or because it's only 802.11g. I'm deducting a star for that alone. All in all surprisingly good performance for a cheap unbranded device!
