Don't use MagicJack - too many unadvertised costs.
I have quite a few jacks (both regular and plus). This last one I bought is a MagicJack Plus.
After 3 weeks, it still would not stay up running for over a day. The port of number costs an extra $20+ and not in their advertising. They also block any other prepaid plan (international) forcing you to use theirs. I have to finally go back to my previous provider and in porting the number from MagicJack back to the original provider, they would force me to pay another $30+ to port it out.
Otherwise they won't release my phone #.
No other provider I know of will do that. Their business practice is just unethical.
