@snowberry The point of this is for you to call your daughter while she’s out and about in Japan, right?
Here’s how magic jack works: you plug it in to your computer, then you plug a normal phone into the magic jack. Instead of traveling along phone lines, your call is routed over the internet.
What this means is that your daughter would get a magic jack (in the US), and bring it to Japan. In japan, she would plug it in to her computer, and then plug a normal phone into the jack.
You call her ‘magic jack number’—a US number—from any US phone (your home phone or your cell phone). The call gets routed over the internet, to her computer, through her magic jack, and causes her normal phone to ring. Since you’re calling a “US number”, you don’t pay for long distance.
My point: she has to be at home in japan for that to work. You can’t call her cell, because her cell doesn’t plug into a regular phone line. She can call any phone in the US from japan (using her magic jack), but again, only when she’s home.
My feeling is that if she has to be at home, near her computer, you might as well just call her on Skype. For free.
You’re both at home: You can talk to her for free. You can call each other on the computer on skype. Done. No need for magic jack.
You’re away from home, she’s at home: You could use magic jack for this. You can also set up skype in the same way, so that you can call a US number and it rings her computer. If she wants to call you when she’s home, she can do that through her computer as well. All of this is is accomplished through her Skype Online Number which is $18 for 3 months.
She’s away from home: This is the tricky part (and the part that you really want, it seems). Magic jack won’t help you at all.
A better approach (IMHO) is to figure out the most cost effective way for her to:
1. Get a japanese cell phone so she can use it while she’s out and about. This also gives her a way to call local japanese numbers. Most likely, you can get a really cheap phone and a really cheap plan with low minutes, since in nearly every other country other than the US, you pay nothing for incoming calls and texts.
2. Figure out the cheapest way for you to contact her when she’s out and about. That means finding a cheap way of calling a Japanese cell phone. When I was calling abroad, Skype had fantastic rates.
Does this describe the problem you’re trying to solve?
