Japanese Cell Phones in America? (questions~ Please read)

by xkoi_kanax / December 31, 2007 10:33 PM PST

Okay~ So I was wondering if
I could buy a Japanese Cell Phone on
the Internet?
I have an American cell Phone with T-Mobile,
But I have a trouble communicating with my friends in
American Cell Phones cannot type Japanese,
And I don't do Romaji well (And I don't know English well either!)

So would it be possible to buy it off the internet,
then use it in America??

If you can help, I'd much appreciate it!
Thank you!

Years ago...

Japan consistently altered the cell frequencies to never match any mass produced unit. There is no question why they did that. Be sure to check if your phone works with the local cell company equipment.

End of 2008??

Verizon wireless announcesed they will allow hardware and software from other companies if the hardware and software meet Verizon's standards..
Check this news..

I am not sure the networks in Japan.. But many Koreans use CDMA.. so they can bring korean phones to the verizon networks..
Sorry, T-Mobile is GSM network.. Maybe, Apple iPhone, a GSM Phone, can use japanese but you need to hack the phone to use it in T-Mobile network and typing in japanese.. This is avoiding hardware warranty..

Yes you can use a Japanese phone in America!
by PathmarkPolice / January 2, 2008 4:22 AM PST

The answer is yes, BUT you must make sure the phone you're purchasing from Japan:

1.) Is Tri-Band 900/1800/1900 make sure it operates on these frequencies. You can pop out your T-Mobile sim card and put it in your Japanese Phone.

2.) Is Unlocked! Make sure the phone from Japan isn't locked to any carrier.

Also make sure you have a wall adapter for the phone's charger, so you can use it in your home here in the US.

In reply to: japanese cell

Check which frequencies the phone operates on. In the US, 850 and 1900 mhz are used for voice services. If your phone does not include those frequencies there is nothing you can do to make it work in the US. Some foreign devices may have either 850 or 1900 mhz instead of both.

how much
by Broke Down Mouse / February 1, 2011 5:50 AM PST

Do you remember how much you paid? My wife is from Japan and I could probably get a friend of hers to bring one but I wanna know if you think it's worth the time and expense. And what's a hypersim?

Update. Yes, Japan swapped frequencies
by R. Proffitt Forum moderator / February 4, 2011 12:33 AM PST

And no phone that works in Japan worked anywhere else.

For example KDDI's CDMA frequency differs from those you use in the states.

This will change soon.

I'm not a rich person, nor am I a businessman But I know how to get the American youth to buy Japanese Cell phones. Its so easy. I'm suprised that No one has don this, yet. lol. during my travels and various jobs I've learned what the worlds youth want. Ive even done a few experiments with phones. Infact I personally boosted the sales of nokia, in sanfrancisco, and Dubai. as to show that I could. lol Tech Sales its soo easy. If I like it then I will promote it. Even during the short time spent living in Tochigi I personally pushed the sales of a product that to be honest was ans is worthless unless there are multiple owners.
