Galaxy S 4g with AT&T 1900 3G Band?

joel32137 · Oct 5, 2011

Hey all,

I know the Vibrant has AT&T's 1900 3g band.

Can anyone confirm if the Galaxy S 4G also have the same AT&T 1900 3g band?

What sucks is that these bands are typically not listed in the specs but it's always a pleasant surprise when a t-mo phone has the AT&T 1900 band.

Thanks.

I'm thinking of upgrading to the Galaxy S 4g from the Vibrant but I don't want to give up the 1900 band when I swap to an AT&T sim.

Thanks in advance for the info

Thanks for the reply but according to phonearena, the Galaxy S 4g only covers GSM 1900. Not UMTS 1900.

The Vibrant actually has UMTS 1900 hence Unlocked Vibrants can be used on AT&T's 3G network

However, I know phonearena isn't always accurate when it comes to specs/bands so that's why I'm asking all you Galaxy S 4g owners

the s4g doesnt have the full 3g band hence why it goes from hsdpa to edge and not switch to 3g as it actually lacks the band for it .....

Joel, what did you end up doing?

Can the SGS 4G use 4G on AT&Ts network?

fredmc2020 · Nov 6, 2011

I was at one point able to get Straight Talk 3G working on the 1900 band when I used to live in TX. This was using ATT's network so it is definitely possible.

However a word of caution: from my experience in some areas ATT uses 850 for 3G, which the SGS4g does not support (edge only).

Got my sgs 4g unlocked and tested on at&t sim card ,3g worked with no problem (chicago area)

The unlocked version of this phone does include umts 1900 band so it can pickup 3g signal on that frequency.

On the back of the phone it says it clearly.

the tmobile version also

Bought from tmobile with no mention of ATT BANDS in the specs. Rooted, unlocked and was able to pick up 3g in Dallas,Tx on Att.

Thanks all, I'm glad to hear that T-mo's Galaxy S 4g works with AT&T's 1900 3g band.

I know this may be asking much but for all who's running the phone on AT&T's 3G 1900 band (and if you have time), do you mind doing a speed test on AT&T and posting your results?

Thanks,

Heh, you said penetration.

Okay kidding aside
Yes the SGS4g will run on ATT's 3g band. You won't have 4g though.
I actually used mine on ATT for almost 2 weeks lol

If a carrier support 4G on 1900mhz band would I get 4G without problems??

I'm picking HSPA now

Since this morning, I've been picking up HSPA from AT&T on my SGS4G. Until today it always displayed the 3G icon and the network info said UMTS.

Today I started picking up HSPA. Although crappy speeds, it's HSPA

I have no idea what happened overnight but the network has changed.

By the way, I'm in Wilmington, DE
