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.

Played around with the settings from dialling *#2263# and speeds improved.
Still comments on Radios & ROMs welcome.
I am getting an Verizon S4 for use in Asia. Any idea/guide to make it as a proper phone for GSM Use? What are the things I need to do to make that as a GSM Phone since I will be using the S4 with majority of carriers in India.

The GS4 will work as a GSM phone if the bands match. According to the Samsung specs, it does the following:
2G Network: GSM 850 / 900 / 1800 / 1900 and CDMA 800 / 1900
3G Network: HSDPA 850 / 900 / 1900 / 2100 and CDMA2000 1xEV-DO
4G Network: LTE 700 MHz Class 13 1700 / 2100
Since India is GSM 900/1800, it should work if you install a local carrier's SIM (and configure their APN). But it looks like you'll be 2G.
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
?
Here is a good tip for cheap factory unlocked NEW Galaxy Alphas:
At $ 549. From Canada GSM .
The question like Giant Neutron Stars vs. Black Holes and questions about whether Dark Matter really exists is :
Samsung's complicated inclusion/exclusion of different Radio Bands on dozens
of Models.
GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 900 / 1900 / 2100
4G & LTE
LTE 2100, 1900, 1800, 1700, 2600, 700, 850
Above are the Radio Bands for the Specific Model at Canada GSM.
How does this look for full coverage TMobile USA ?

Anymore info on this on whether it'll work on T-Mobile's 1700/2100 bands? I'm thinking about getting one to see if it works. Hope it's not a typo in their specifications that's listed.
***UPDATE***: DO NOT buy from CanadaGSM.ca website. They are fraudulent. I received a blank confirmation page upon order completion and the chat line said I needed to give them my CC's 3 digit security code even after they've charged my bank account. They also said my product will not be shipped. The number listed on their website is fake as well. Google... beware CanadaGSM.
Hi, does anyone know how I can find out and check that bands and their associated frequency MHz supports unlocked htc one m8 US AT & T phone?
Depending on the ROM, you can enter *#*#SERVICE#*#* (*#*#7378423#*#*) into the dialer to see the bands supported. But this requires Servicemenu.apk installed, and I just tried it on my M8 (running SROM) and it doesn't work for me.
There are also several apps which can tell you the bands supported by the device (LTE Discover, Signalcheck) but I can't vouch for any one in particular.
What exactly are you trying to determine?
AT&T uses 3G Bands 2 and 5 (850 and 1900 MHZ) and LTE bands 2, 4, 5, and 17. Based on device specs from here, the AT&T version M8 also supports (in addition to the bands used by AT&T) 3G Band 1 (2100 MHz) and LTE Band 7.

Hi RP73 thank!
Because of problem to connect may hTC M8 in Croatia EU area out of city on the the G3 900MHz band I would like to check which band really support my device. Other wise some check applications see my device as US brand AT$T other as Europe GSM device? hTC was bought as factory unlocked!
