Two weeks ago, we discussed how MagicJack recently became the fastest growing phone company in the US. Well, today twice.com reports that MagicJack is on track to reach 500,000 subscribers. Not too shabby considering the population of Tampa, Florida is about 300,000.

If MagicJack reaches 500,000, they will be the second largest VoIP provider; with only Vonage’s 2.5 million plus internet telephone subscribers ahead of them. The twice.com article talks about the MagicJack business plan and some of their future ideas. It’s not a bad read.
