Need Help with Ntt Docomo D905i... Unlocking

[stinko0man]

The success of the Taiwanese team could have not come at a better time . Hopefully DoCoMo will continue to produce phones with both 3G and GSM capabilities. Having to use two phones is really quite an inconvenience.

Just to clarify, the modern DoCoMo phones are supporting three 3G bands - '800', '1700' and '2100'.

800 - The so-called Japanese 850 band, called 'FOMA Plus' by DoCoMo's marketing bunch. It's this band support that allows DoCoMo phones to work on 3G 850 networks outside Japan.
1700 - A band unique to Japan. This band was added to alleviate bandwidth congestion issues on the 2100 band in cities.
2100 - The regular 3G 2100 band, used in Japan and across the world.

For the record DoCoMo phones don't support 3G 1900. GSM wise they're typically supporting GSM 900/1800/1900.

Hmm, the American T-Mobile uses the 1700 band as well, and very soon Canada will probably have that as well. I wonder if that'll somehow work here too...

[AL9999]

No it won't. The American AWS band is different to the Japanese 1700 band.

The American AWS band pairs 2100 for RX with 1700 for TX, whereas the Japanese 1700 band uses 1700 for both RX and TX.

So, they're not interchangeable.

[KBoardBox]

Too bad for our American friends then.

[stinko0man]

What about 2G? ATT is also GSM, does that mean that the band range of the DoCoMo phones are incompatible?

[KBoardBox]

DoCoMo phones will run on the 1900 GSM band, if available.

DoCoMo phones will run on the 1900 GSM band, if available.

And there's still 850MHz 3G available.

[KBoardBox]

Damn straight.

hmm, its tempting to pick up an older 903i series and try 3g out since i might have 850 3g

Yeah- where I live secondhand 903i phones are going for <US$100 so it's a chance to save a lot of money. I think the SH903i looks nice but when I get back to the States I don't know if where I'm going (Boston area) will have 850MHz coverage. And there's that issue of incoming calls not working on 3G, but then again, I'd like being able to keep in touch with people on my own terms...

Does anyone know how much should a p905i cost? Where can I buy it an do you think it would work in Mexico?

[wolvorine4424]

Buying will be a hard one. Unless you have a friend or someone on this board that can get it for you. (they have to be in Japan)

Let me check the specs and see if it will work. But as far as I know, not sure if you can unlock it just yet.
