Question about compatible bands - Android Q&A, Help & Troubleshooting

I have t-mobile. I still don't understand what bands need to be covered for t-mobile. I'm thinking about buying a Xiaomi Redmi 4 prime. I live in the USA, I want to know what bands should be available for me to use the phone. I already checked http://willmyphonework.net/ and the Redmi 4 Prime is not listed. The bands on the phone pulled from gsmarena are:
Technology
GSM / CDMA / HSPA / EVDO / LTE
2G bands GSM 850 / 900 / 1800 / 1900 - SIM 1 & SIM 2
CDMA 800 / 1900
3G bands HSDPA 850 / 900 / 1900 / 2100
CDMA2000 1xEV-DO & TD-SCDMA
4G bands LTE band 1(2100), 3(1800), 7(2600), 38(2600), 39(1900), 40(2300), 41(2500)
Speed HSPA, LTE
GPRS Yes

According to this page:
https://support.t-mobile.com/thread/126498?start=0&tstart=0
I could see that Xiaomi Redmi Note 3 has the same 4G bands as the Xiaomi Redmi Note 4, and the first answer which marked as the Correct Answer says that it won't get any 4G support With T-Mobile

Radios---- AT&T: GSM/GPRS/EDGE (850 / 900 / 1800 / 1900), WCDMA ( 850 / 1900 / 2100), LTE (700 / 850 / AWS / 1900)
------------ Sprint: GSM/GPRS/EDGE (850 / 900 / 1800 / 1900), WCDMA (700 / AWS), CDMA (800 / 1900), LTE (1900)
Radios---- T-Mo GSM: (850 / 900 / 1800 / 1900), WCDMA: (850 / 1700 / 1900 / 2100), LTE: (Band 4 / Band 17)
Internal storage AT&T: 32/64GB; Sprint/T-Mo: 32GB
what are they
internally all of the GSM models, except for the Dual Sim Chinese models are the same
The sprint model, due to CDMA and LTE radios on board are different, the partition layout isn't the same as the others

A radio doesn't add bands to your device automatically

Is the Alpha fully compatible with US AT&T?

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
?

Galaxy Alpha SM-G850F(Europe) will it work in Australia?

Howdy folks, I'm wondering if my SM-G850F will work in Australia (Melbourne) ? Any information is greatly appreciated
Cannot attach an image of the phone details :/
Android 5.0.2
Baseband G850FXXU1COI1
you need to check if your provider works with the same bands as the ones on the F model.
2G bands GSM 850 / 900 / 1800 / 1900
3G bands HSDPA 850 / 900 / 1900 / 2100
4G bands LTE band 1(2100), 2(1900), 3(1800), 5(850), 7(2600), 8(900), 20(800) - G850F
Yes, it's working like a charm !
Thank you
Thanks a lot! Cheers!

[Q] htc one M8 US AT&T frequency after unlock

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.
RP73
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!

S9+ China on T-Mobile US

I have a new unlocked S9+ China (SM-G9650/DS, Qualcomm Snapdragon 845), and I'm trying to figure out if it is fully supported by T-Mobile in the US. I've done some Googling on this, but I'm not sure I understand the results. The supported band specs for the phone, and the T-Mobile frequencies used, are below. Can someone confirm or comment whether the phone is fully supported, or if not what's missing? Thx, Gus

It will work on T-Mobile frequencies but you won't get Wifi Calling or voLTE. The stock CSC is TGY - Hong Kong, T-Mobile is TMB. I haven't found any way to change the CSC even with custom ROM, but assuming one became available you would trip Knox and lose Samsung Pay, Samsung Health, Secure Folder, OTA Updates and Factory Warranty. Some members have posted in regards to changing the CSC Code in the link below but I'm not certain it's working out. Good luck!

baring any unforeseen hidden stuff, you should be good to go for Tmobile...Minus the new Band 71 on the 600mhz spectrum. Honestly, unless you live in the area that will get this deployment, this shouldn't be of concern. As long as you can use Band 2/4/12, you will be ok with Tmobile.
I almost went with this route as well since I wanted to get a Snapdragon version with larger storage size. But I chickened out because I've been reading people having bad signals/not having full LTE speeds with their imported S9+ on TMOUS.
Good luck and let us know!
I used CT Excel Americas (T-mobile mvno) and it worked on CHC firmware. But I forgot to test volte etc.
