Just a little bit of info.
2G:
All versions: GSM 850 / 900 / 1800 / 1900
3G:
S5830: HSDPA 900 / 2100
S5830L: HSDPA 850 / 1900
S5830B: HSDPA 850 / 2100
Thanks to davebyone for the help gathering the info.

That's a S5830.
GT-S5830 Qualcomm HSDPA
Noob help, very please, and sorry for the stupid question. I bought GT-S5830 in Australia, factory unlocked. Want to use it in the U.S. with AT&T SIM 3G. All I get now is EDGE.
Does the info below mean I need a different CHIP/Phone to get S5830L or is there a setting I can change somewhere under a *#*# code to get this so I can use 3G (since I THINK AT&T requires S5830L: HSDPA 850 / 1900 to get 3G)?
-----data from previous post below------
[INFO] GT-S5830, GT-S5830L and GT-S5830B frequency bands
Just a little bit of info.
2G:
All versions: GSM 850 / 900 / 1800 / 1900
3G:
S5830: HSDPA 900 / 2100

S5830B: HSDPA 850 / 2100
You cannot change the radios on your phone, so if you're sure you have the HSDPA 900 / 2100 version there really isn't anything you can do to get AT&T HSDPA 850 / 1900.
Hello
Tried to find out the answer in these forums but can't find it.
I bought an AT&T I717 for the faster processor and lack of a physical home button (prefer the look) but not sure it's compatible with our data networks?
GSMArena gives:
i717
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 1900 / 2100
4G Network LTE 700 MHz Class 17 / 1700 / 2100
N7000
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 1900 / 2100
4G Network LTE 700 (region specific)
I've got a nasty suspicion that my Three UK network might be using 900 MHz 3G. The only frequency not on the i717.
en.wikipedia.org/wiki/UMTS_frequency_bands#cite_note-9
Can anyone else confirm this is the problem or is it the stock AT&T Radio? Would rooting and installing another Radio & ROM make any difference or should I attempt to sell it and get an N7000?
Any serious help much appreciated.
*#2263#
Played around with the settings from dialling *#2263# and speeds improved.
Still comments on Radios & ROMs welcome.
i was gonna ask if it possible to get AT&T 3G bands 850 & 1900 Activated on this phone thanks. if you know about this you can help me thank you..

The U20i supports gsm (2g) on 850, 900, 1800 and 1900
and HSDPA (3g) on 850. 1900 and 2100 by default...

You're right... I accidentally listed the networks for the U20a...
The two types were sold in different regions. (or by different providers, dependant on which frequencies they used), but there is no way to make it work on other frequencies... it's a hardware issue as far as I'm aware.
Hi....i got a little problem in my country we have Orange Dominicana from Dominican Republic...supposely their 3G network is this one:
CDMA N/A
GSM/EDGE 900 MHz / 1800 MHz / 1900 MHz
3G 900 MHz
But i have the i717 and when i go to *#2263# to force in to 900 band it will only read edge so its kinda slow. but when i use my phone in Claro Dominicana network they have:
CDMA 1900 Mhz
GSM/EDGE 850 MHz / 1900 MHz
3G 850 MHz
It works perfect in 850...the 4g icon appears on my bar. Now ppl say its because the att wont work on orange and only the international version will, i dont know that, is there a way i can solve this? maybe flashing the international modem on my i717 or are they the same? Thanks!
Why two threads?
It seems like the Samsung Galaxy Alpha has all the necessary bands to be used with AT&T in the US. But does anyone know for sure? If Samsung takes too long to release this in America can I buy the UK version and use it in the US?
Thanks

Bump. I have the same question.
GSM Arena says this about the device:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 1900 / 2100
4G Network LTE 800 / 850 / 900 / 1800 / 1900 / 2100 / 2600
If what wikipedia says, AT&T uses the following frequencies:
2G: 850 / 1900.
3G: 850 / 1900.
4G: 700 block B (main frequency) / 1700 AWS / 1900 / 2300.
So, if I read correctly, you can use the international Alpha for 2&3G, but for LTE, you are covered only by one LTE band, 1900, and this being not a main frequency, won't have good coverage everywhere, I think.

Does this pertain to HSPA+ too?

HSPA+ is 3G, so you shouldn't have problems with it.

So I'd get HSPA+ anywhere I'd get it from an AT&T phone, just not LTE necessarily?

Yes. If it was me to make the decision, I'd want my phone with an unlocked bootloader, HSPA+ is good enough speed for me.
Though, practically, I've never tested LTE in my life, until recently we didn't have any 4G networks.
International Galaxy Alpha NO US LTE on ATT or TMO

I bought an unlocked international/Euro Galaxy Alpha SM-G850F at the London Samsung store... Installed my USA ATT SIM and have no prob w. calls or H or H+ data but can NOT get LTE band in the USA on either ATT or TMO even though the device seems to have the right bands for ATT or TMO LTE. On advice from an ATT Wireless store manager, I updated my APN settings to match ATT setup but still did not get LTE. FYI my H+ is quite fast for most purposes but I want LTE. Hope that answers your question.... Mine is how can I get LTE???

Are you sure the European version has correct U.S. LTE bands? I was under the impression that it does not....

I am trying to solve this also.
I think that the Euro Version with the Exynos does not have the proper LTE Bands for North America LTE.
But the Qualcomm version does, though not sure about
TMobile.
I am looking at this from Canada GSM for $ 549. Factory Unlocked with following Bands:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 1900 / 2100
4G & LTE 2100, 1900, 1800, 1700, 2600, 700, 850
Obviously for AT&T you just buy theirs.
I have read that the EXYNOS versions do not function in North America on LTE.
With all phones it seems that you must be very very
Specific about Model Numbers including Suffixes etc.
Especially SAMSUNG loves to make 24 versions of ALPHA, 50 versions of S4 etc.
Frequency Bands are a real WTF for amateurs like me:
For example are there TWO DIFFERENT 1700 bands, one for4G LTE and one for 3G , HSPA + or are they the SAME BAND with dual usage ?
In example ABOVE the Alpha Factory Unlocked Canada GSM @$ 549.
IF used for TMobile the LTE Bands look fine, but the 3G
1700 Band is not there. Will 3G merely use the 1700 LTE
band or does the SOC ( QUALCOMM) need to have
allocated the 1700 band for dual usage LTE and.3G
?
