3g in usa

I heard that 3g does not work in the USA with the hero. But when i look at the specs for the phone(below) its like the exact same as the g1 (besides added 900 for hspa). So does 3g work in usa?
Network HSPA/WCDMA:
*
900/2100 MHz
*
Up to 2 Mbps up-link and 7.2 Mbps down-link speeds
Quad-band GSM/GPRS/EDGE:
*
850/900/1800/1900 MHz
(Band frequency and data speed are operator dependent.)

Check the official stats for the European version:

HSPA/WCDMA:
•900/2100 MHz
T-Mobile uses 1700Mhz, so that won't work. AT&T uses 850Mhz and 1900Mhz so that won't work.
The 850/900/1800/1900 MHz bands mentioned are for GSM. So Yeah GPRS/Edge will work.

Will my international GT-I9000 be compatible with T-mobile 3G speed?

I've seen a lot of isues with phones on t-mobile locked on EDGE speed...
I was wondering if my phone, a galaxy s international (french) was compatible with 3G or maybe H+.
I can't seems to find any good informations...
Wikipedia : Dual band CDMA2000/EV-DO Rev. A 800 and 1,900 MHz;
WiMAX 2.5 to 2.7 GHz;
802.16e 2.5G (GSM/GPRS/EDGE): 850, 900, 1,700, 1,800, 1,900, and 2,100 MHz;
3G (HSDPA 7.2 Mbit/s, HSUPA 5.76 Mbit/s): 900, 1,900, and 2,100 MHz;
but i think it include every version

Unfortunately your phone won't get 3G but you can get AT&T 3G. It's weird you have 1700 MHz 2G. I wonder if that could be unlocked for 3G? That's the only 3G frequency you are missing.

If you are asking about T-Mobile in the U.S. then perhaps...T-Mo/USA is re-farming some 1900 MHz for 3G operation in some select cities/locales. And your phone does support 900/1900/2100 MHz 3G, so in theory, and if in certain locations, then yes, you may be able T-Mo 3G via 1900 MHz.
From the press release:
As part of the company’s network modernization effort, T-Mobile also plans to launch 4G HSPA+ service in the 1900 MHz band in a large number of markets by the end of the year.

I've heard about Los Angeles, New York City, Miami, Boston, Washington DC and there have been individual reports from many other locales.
AT&T does also have 3G on 1900 MHz in some locales: http://www.cellularmaps.com/att_850_1900.shtml
But I am not sure if they have ceded some of these to T-Mo as part of the failed merger, and/or transitioned those to 850 MHz?
Both AT&T and T-Mo do offer pre-paid SIMs and services - and there are some MVNOs like StraightTalk reselling AT&T and T-Mo network access.

Any suggestions for sub $300 tablets with 3G/4G?
Maybe the Nexus 7 3G is the better option?

Suggest you be specific about what network you intend to use the device on.
I have the SCH-i905 and yes it works fine with CM10 but it is Verizon only and I have not seen any info on how to unlock it to use on other networks (have seen several posts asking, just never any definitive answers).

Thanks for the reply.
Either CDMA2000 or UMTS is ok for me.
So no unlock method for SCH-i905.

Samsung Rugby Smart 3G?

Hey!
Is it possible to change or unlock the UMTS 900MHz frequency in Samsung Rugby Smart?
Frequencies and Data Type
GSM: Quadband:850/900/1800/1900MHz
UMTS: Triband: 850/1900/2100MHz HSPA+ 14.4 MBps
I live in Finland and needed frequency is 900MHz / 2100MHz in UMTS
GSM should work fine?
So it should be fine for calling, but internet is a bit slow maybe?

T-Mobile Dropped My Spectrum?

I'm currently using a Samsung Galaxy S4 I9505 International (GSM card)
I'm now getting data speeds of 0.13 Bps. That can't continue.
I'm When I spoke to T-Mobile support they told me that the 1900 Mhz spectrum (LTE) is being dropped for the new 600 Mhz spectrum. This is for 5G. They advised me to get a phone that has 600 Mhz (phones not available yet) and 2100 Mhz spectrum. In the data below you can see that my phone can use 1900 Mhz for 2G and 3G. This is a mess. Apparently the 1900 Mhz my phone used to use (and provided quite good data speeds) has already been dropped, but the 600 Mhz I will need is not yet in phones currently being sold. What do you recommend I do?
The changes are related to T-Mobile aquiring new frequencies so they can improve service and data speeds. This implies that T-Mobile dropped a frequency which my phone used (1900 Mhz?), and which used to give me quite good data speeds.
So my slow data speeds are the result of changes made by T-Mobile. I brought my own phone, and did not purchase from T-Mobile, so they didn't offer me a new phone cheap.
My research shows me that my area has 700 Mhz LTE. But apparently my phone can't use that.

Samsung Galaxy S4 - Wikipedia
2G: 850, 900, 1800, 1900 MHz, GSM / GPRS / EDGE
3G: 850, 900, 1900, 2100 MHz, UMTS / HSPA+
4G: 800, 850, 900, 1800, 2100, 2600 MHz

Get a device that uses US LTE bands. Your only other option is to risk bricking your S4 to add US bands to its radio chip.
