Help AT&T 3G compatible?

[sodaboy581]

Although I'll probably be using this on T-Mobile for awhile, on the official specs page, it lists several frequencies: Official T-Mobile G2 Page.

It looks like this phone might be able to do AT&T's 3G as well? (AT&T uses 850mhz/1900mhz, right? They're both listed.)

Feel free to correct me if I'm wrong!

Those are Edge frequencies. UMTS(3G) are the standard TMO 1700/2100.

As Swizz says, those are GSM frequencies. This is a strictly Band IV phone, which means only T-Mobile and a few smaller carriers in the US.

There is an HTC press conference this week though. Perhaps they will announce a European version which will support 850Mhz or 1900Mhz frequencies.

I'm looking into either switching to t-mobile or
Using with Att.

Why is the samsung vibrant compatible with AT&T 3G and this is not?

The Vibrant is a spinoff of the Galaxy S. The Captivate is AT&T's version of the Vibrant. The Vibrant has T-Mobile's UMTS bands, the Captivate has AT&T's UMTS bands.

In short, the Vibrant will not work with AT&T's 3G.

Wrong! The vibrant does work on AT&T 3G if unlocked.

According engadget (Confirmed: Galaxy S unlock codes are stored in your phone, Vibrant capable of AT&T 3G -- Engadget)

The vibrant does pick up AT&T 3G speeds

To be fair, only half wrong. After a little research, the phone is capable of 1900Mhz but not the 850. While 1900 is used more often, it does not have the same penetration that 850 has. So 3G will not be as advertised.

/I love when people go "Wrong!". Douches.

Apparently where I live and at my work place, and and pretty much everywhere I go, my UNLOCKED Vibrant can get ATT 3G service with no problem. Heck, it even works better than my Captivate cause Att locked a lot of things on the Captivate including the market and 3rd party softwares. I had to flash it with a custom rom in order that my Captivate worked like the Vibrant. The Vibrant DOES work with Att 3G data.
