You know everyone has a mobile broadband card when Virgin Mobile is going to be carrying one… We just got word, and this screenshot, from one of our ninjas saying Best Buy is going to be carrying the data card starting June 14th. Just like everything else from Virgin Mobile, there will apparently be a prepaid option as well! Do you find yourself constantly worrying that you’re about to pass the 5GB softcap on your plan? If so, prepaid can definitely put an end to your troubles. Pricing isn’t solid yet but as far as monthly plan options go, we’re told it should be competitive with Cricket — possibly $40 for 5GB and a cheaper 1GB plan as well — and the card itself will run $149.99. Details on how prepaid will work are not yet avaialble.
