the diamond in various conuntrys

hey!
Does anyone know if a diamond bought in the US will work in Israel?
You can go to www.gsmworld.com and then roaming, and then coverage maps. (pick a country)
Here you will see all the various networks in that country and the bands they use. For Israel all networks use 900, 1800 or 2100 (3G).
Since the only diamond you can buy right now uses 900, 1800, 1900 GSM and 900, 2100 3G, it will work perfectly in Israel.
I also want to add that HTC diamonds bought in the US currently is the Europe/Asia version (lacking the 850 band). This will/might change sooner or later.

Upgrade the radio software to connect 3G

Hello to all. Bought a week ago TD2 released in New York to use it in Brazil, net 3G of the operator Claro. It happens here in Brazil operates in the TD2 not 3G for data transmission and is always in EDGE mode, although there is availability of the 3G network. I heard that HTC has limitations in the software radio to create niche selling to carriers, so the same hardware, with tables of frequency band, or can not work on different carriers using the same frequency of band. I ask if the exchange of software to radio TD2 can make it recognize the 3G network.
Thanks in advance

Claro uses the 850/1900 MHz band for 3G.
You've probably bought the European version of the TD2 which only supports 900/2100 MHz bands.
This is defined by hardware - you can't change it by flashing a different radio.

Xperia x2 3G bands.

can anyone with a european xperia x2 confirm what 3g bands it has.
i keep on reading conflicting theories.
either its UMTS 900/1900/2100 MHz or UMTS 850/900/2100 MHz.
i think they are already being sold in the netherlands.
which one is it?
thanks
Any european variant of a SE handset always has 3G bands:
a) 900/2100MHz
or
b) 900/1900/2100MHz
but i saw some websites it says that it has 850mhz 3g plus i need to know if it has the 1900mhz because in manhattan where i live it works on 1900mhz 3g.
The XPERIA X2 white paper says
a) X2 (European) has 900/1900/2100MHz 3G bands
b) X2a has 850MHz/1900MHz/2100MHz 3G bands

[Q] 850 band on GT-I9000

hey,
i have a GT-I9000, and i'm trying to enable 850mhz band for 3g,
i flashed the jjjv5 modem which is 850enabled,
and selected the 850 band through *#2263#*, the second i select 850 i get no signal, does that mean my phone isn't 850mhz capable or does it mean there is no 850mhz reception in my area ?
galaxy s suports all bands
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 900 / 1900 / 2100
so you dont have 850 band in your area.
perhaps i was not clear - i'm trying to connect to 850mhz WCDMA band, not GPRS/GSM.
where do you live ? do you have the international i9000?
i live in israel, where we have a 850mhz/2100mhz 3g carrier (Pelephone)
the phone was purchased privately, not from the carrier.
i'm not quite sure about the phone version, the box states UMTS bands as 2100,1900,900.
the writing on the box and every document about the phone states GT-I9000.
does that mean that 850 3g band is not possible for me ?
i9000 doesnt support israel's 850 3g band, you can use 2100 instead which is suported by both ,phone and carrier

I'm also having a similar problem. im in Honduras with Tigo paid for 3g but only connecting to edge, i have the gingerbread xwjw5 build. I have a unlocked gt-i9000
only if you have the I9000T you can use the 850 band

Enabling 850 Band

Hi,
I own a HTC One, european version. But as I am living currently in south america, I can not use anything faster than EDGE, as the EU Version only supports 900 Band upwards, whereas overhere the band of choice for quick data is 850.
Is there a way to activate this band?
Thanks, Tom
