I would love to be able to use this amazing phone in on T-Mobile in the US without crippled data speeds as well as seamlessly on voice. Anybody here have experience with this new phone on this network?
ST18a is supposed to be for AT&T, but I speculate that ST18i might be better for T-Mobile US due to 900/2100MHz. 1700MHz is missing though. I also don't know how accurate this is:
hxxp://en.wikipedia.org/wiki/T-Mobile_USA#Radio_frequency_spectrum_chart
Just today a T-Mobile Tier2 told me all I needed was 900 / 1800 / 1900MHz for 3G, and 1700 and 2100 for 4G.... so I am left very confused.
Note even access to 3G via roaming on this phone would be acceptable.
just to relieve you from misunderstanding, the ray is not 4G, and the bandwidth 2100 is 3G, and is used mostly in europe and asia pacific, which ever version you get, the umts is available in 5 bandwidth and are all 3G
Hi kms108,
What's your experience with the ST18i? Are you using it in the US? Possibly on T-Mobile?
Thanks!
i have the hong kong version, which is unbranded and using it in hong kong.
i'm liking it very well, just the right size to hold, not a android phone on the market to match it in quality, specs and size wise.
Xperia ray DOES NOT support 3G from Tmobile.
I own the device and I learned it the hard way.
Although ray supports 2100 MHz, the only device that can access Tmobile 3G is the one with BOTH 1700/2100 MHz. It is because Tmobile split both frequencies: one for download and the other for upload.
While for other carriers your phone will work in 3G if it supports either one of the frequencies, however, Tmobile is different.
Having said that, almost ALL of the unlocked phones in the market won't be capable of accessing Tmobile 3G.
If you wish to access 3G, the only carrier that will work is AT&T.

Which version, ST18a or ST18i, did you buy? See following:
hxxp://androidforums.com/sony-ericsson-xperia-ray/443709-3g-4g-us-t-mobile-using-st18a-st18i.html
Mine is the ST18i.
Well, neither version will support Tmobile 3G.
ST18i UMTS HSPA 900 (Band VIII), 2100 (Band I)
GSM GPRS/EDGE 850, 900, 1800, 1900
ST18a UMTS HSPA 800(Band VI), 850 (Band V), 1900 (Band II),
2100 (Band I)
GSM GPRS/EDGE 850, 900, 1800, 1900
Here's the specs from the manual.
Since both are missing 1700, neither will be capable of receiving 3G from Tmobile.
AT&T
What irony -- maybe the AT&T acquisition of T-Mobile will have some benefits after all, especially those who buy the ST18a...
This wikipedia link confirms your experience: hxxp://en.wikipedia.org/wiki/T-Mobile_USA#3G_upgrade
The Xperia X10 had 1700, too bad Sony eliminated it.

I got a V19 phone from china with Android 5.0. I believe it is a rooted phone, I've seen some of those features. It came in a box that says Android. I have no idea of the manufacturer.
Problem: I cant get the data connection (tmobile, wifi works fine) to get better than the edge network, 2G. I've learned that T-Mobile requires these bands:
LTE Frequencies:
1700 MHz & 2100 MHz AWS band 4
1900 MHz PCS band 2 (in refarmed areas)
Lower 700 MHz band 12 (in development) / in service in selected areas
3G/4G Frequencies (WCDMA):
1700 MHz & 2100 MHz AWS band 4
1900 MHz PCS band 2 (in refarmed areas)
2G Frequencies (GSM/GPRS/EDGE):
1900 MHz PCS band 2
Inside the battery area the phone lists :
GSM 850/900/1800/1900mhz
WCDMA 850/2100mhz (HA)
When I got to engineering mode, I can see other bands that are greyed out.
So my question is this. Is it possible to slick this phone and install software, etc, that allows the bands I need? Or are 'Bands" hard coded into the hardware of the phone? Easier to just buy another phone with correct bands? Advice or links?
Thanks,
Gary B.
my v19 from china same as yours bro.. it says android 10.0 but its features says 6.0ver
Hi, last week I was given a Moto G3 XT 1541 from Spain. The problem is that it doesn't connect to argentinian carrier's 3g or 4g bands, it only works on 2g. A friend told me that I could work it out flashing the firmware of another model like XT1540 which works perfectly on 3g and 4g. Is it a firmware block? Can I solve it flashing another model's firmware? If I flash it, will my phone work or it will be a stone? Thank you ver much.
Yes, you can.
Moto G 3rd generation does not have capability of 2300 MHz bandwidth.
Requirements for a4G
1. A handset that supports 2300Mhz.
2. A 3G plan.
3. USIM (they provide free upgrade)
4. 4G network coverage
I think even HSPA or HSPA+ might not work for me on this phone. I am using a T Mobile family plan here, and comparing th bands given on the website:
"4G (HSPA+)
With 4G, theoretical maximum download speeds range from 21 Mbps up to 42 Mbps. You can take advantage of incredibly fast download speeds, and even use voice and data services at the same time.
Frequencies: Band 2 (1900 MHz), Band 4 (1700/2100 MHz)
3G (HSPA)
With 3G, theoretical maximum download of 14 Mbps. With 3G, you can use voice and data services simultaneously.
Frequencies: Band 4 (1700/2100 MHz)"
"Moto G (XT1550)
LTE (1, 3, 7, 8, 28,40) UMTS/HSPA+ (900, 2100, 850 MHz)
GSM/GPRS/EDGE (850, 900, 1800, 1900 MHz)"
It seems that the uplink is unsupported by my phone and so the phone is unable to use the HSPA/HSPA+ bands. I think the only way to use it is to unlock the 1700 MHz band on my phone.
XT1541: GSM/GPRS/EDGE: 850, 900, 1800, 1900 - UMTS/HSPA+: 900, 2100 - LTE: B1 (2100), B3 (1800), B7 (2600), B8 (900), B20 (800)
Argentina UMS/HSPA+ works on 850 and 1900.
This phone will only get 2g where you are. Flashing another firmware will not fix this.
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.

Please post steps for this. I would like to get VoLTE and Wifi calling
Hi, i'm about to buy the Honor 9, but I have a problem. I will buy it in Amazon (Europe) and ship it to my country (Argentina) that uses this bands:
2G (EDGE, GSM/GPRS): Bands 850 / 1900 MHz
3G (HSPA+, UMTS/WCDMA): Bands 850 / 1900 MHz
4G (LTE): Bands 4 (AWS o 1700) / 7 (2600) / 28 (APT o 700*)
(the most important band is the B4 AWS, the others are not that important)
And I searched on google and I found differences, some places say it has the b4 band(frequencycheck.com,phonedb.net), others say no (gsmarena)
Amazon says its the model 51091SNW, but assume is the STF-L09 version
So I need your help, if anyone of you has bought this phone in Europe and wants to confirm if it has the band that I need, I would be grateful. Otherwise, I'll have to choose another phone because a phone without 4g nowadays it's not good
Thanks in Advance!!!
I checked the price comparison I usually use and which is usually pretty well informed (this is their English page, the company behind it is originally from Austria):
Frequency bands: GSM (850/900/1800/1900), UMTS (850/900/1900/2100), LTE (B1/B3/B5/B7/B8/B20)
https://skinflint.co.uk/a1638115.html
Same info from my go-to review site (translated from a German review):
Networking: 802.11 a/b/g/n/ac (a/b/g/n/ac), Bluetooth 4.2, GSM 850/900/1800/1900, UMTS B1/B2/B5/B8, LTE B1/B3/B5/B7/B8/B20, Dual SIM, LTE, GPS
https://www.notebookcheck.net/243422.0.html
Both is for the STF-L09, which is sold throughout Europe, so I guess it doesn't matter that both have their info from devices from Germany...
It seems to lack Band 4, and according to gsm arena it does so for all Honor 9 models available
