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 have a tmobile galaxy S vibrant which i believe is on the 1900 cellular band and the data is on the 1700 band.
i am traveling to a country which is on the 900/1800 cellular band and 2100 data.
will my phone work there with a locally purchased sim?
im going to israel
will data work if buy a local data package? (edge or otherwise)
thank you

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!
oh by any chance will this work? http://forum.xda-developers.com/showthread.php?t=1547114
they talking about 1700 band and not the 900 so i dont know
Sorry. The modem chip in the note is 850 and you can't change it.
Hi,
All Guys in Singapore specially pay heed
I bought this lovely phone to be able to enjoy quad core for one and LTE data access. It seems that when I try to connect to the 4G LTE on Starhub (in Singapore), I only get 4G, not the LTE speeds.
Please correct me if I am wrong, that the e970 has 1700 and 2100 band for the LTE, while Singapore only has 1800 and 2600 bands available.
Is there any possibility of enabling 1800 and 2600 bands?
The local variant is the E975, can I flash the stock e975 firmware to the e970 without adverse effects?

2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 1900 / 2100
4G Network LTE 700 MHz Class 17 / 1700 / 2100
You can use 2G, not sure what the 3g band is in Singapore.

My quick search shows Singapore uses 2100 for 3g, so the phone will support it. However, you cannot add or enable new frequencies. The hardware does not support them unfortunately. Your local LTE is not compatible with the E970

You can use 3G/HSPA+, I was there last week and I was getting 5-6 Mbps using SingTel prepaid.
EDIT- No LTE, sadly. But 3G was enough for anything I'd do on my phone.

HI,
yes the HSPAP works quite well. Im on the StarHub network, I also get a decent data rate. But LTE is LTE, it would have been nice to be able to coax the E970 somehow into those bands.

Hello all. I've just got LGOG recently. Everything seems to work fine except I can't get HSDPA or 3G with this phone. With Nexus 4 and my current sim, I can get HSDPA and/or 3G in the same area. I use the same apn setting but I can only get Edge on my OG.
What I have tried:
- Got to the service [email protected] Only and change Network mode to WCDMA 1900 >>> didn't work. Shows only EDGE.
- Service [email protected] Only then RAT selection and change to WCDMA only >>>> phone won't get any signal.
I would be appreciated if anyone can shred some lights. I was about to sell my Nexus 4 but I have to think again if I can't even get 3G with OG in my area. Thanks!!!
What carrier are you on?

I am using Walmart family mobile. The APN is set to use epc.tmobile.com in Nexus 4. I tried the same thing in LGOG but I have no luck.
Not sure what's wrong with your phone. I switch between my nexus 4 & og when the batteries die, and data always work.

Is it about the 1700/2100 frequency that OG uses for LTE ? I took my friend's AT$T sim card and put in my OG. The 4G works fine.
Ace42: I saw your post about flashing OG radio to N4 radio. Will the flash mod the radio of OG to be exactly the same as what N4 has? For example, will it change from:
GSM: 850, 900, 1800, 1900 MHz
UMTS: 850, 1900, 2100 MHz
FDD LTE: 700 (band 17), 1700/2100 (band 4) MHz
to:
GSM: 850, 900, 1800, 1900 MHz
UMTS: 850, 900, 1700/2100, 1900, 2100 MHz
If so, I would like to try it out but is the mod reversible ? I am pretty new about this so please excuse met if I might ask some stupid questions. Thank you so much.

The radio bands are hardware dependent, you will not get additional bands from a radio. It is just the att modems may give no mic or speaker audio on T-Mobile and its MVNOs.

Thanks for the clarification. I actually tried to flash the phone last night and it doesn't work. I think I will just need to wait for T-Mobile to refarm this area then.

They mostly rearmed major cities, there's a service map that shows how very few areas have rearmed 1900.

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.

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.

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???

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
?
