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

I have the HTC Radar 4G on T-Mobile. Once I unlock it and use it on At&T, it will definitely do calls, but will it pick up 3G or 4G on the AT&T network? I asked HTC and they were unsure. Thanks!
Do a search in this forum to find your answer.
Sent from my Titan using XDA Windows Phone 7 App
AT&T uses 850 MHz / 1900 MHz for GSM/GPRS/EDGE and the same two frequencies (850 / 1900) for UMTS/HSPA (their 3G/4G service).
T-Mobile uses the same frequencies (850 / 1900) for GSM/GPRS/EDGE, but uses 2100 MHz and 1700 MHz for UMTS/HSPA/AWS (their 3G / 4G network).
If you want to know what phones will work where, compare the frequencies they receive with those of the carrier you want to use.
In the case of the Radar, it uses the following frequencies
GSM/GPRS/EDGE: 850 MHz; 900 MHz; 1800 MHz; 1900 MHz
UMTS/HSPA: 1700 MHz; 2100 MHz
So, for GSM phone calls and data you have a match with AT&T (and, of course with T-Mobile). 3G / 4G is a different story. The Radar has the T-Mobile 3G/4g bands, but not the bands for high-speed data on AT&T.
So, if you are happy just making phone calls and using EDGE data, then you can use the phone on AT&T. If you want 3G /4G as well you have to stick with T-Mobile.

I finally was able to get the h2O SIM card (AT&T service) and surprisingly it picks up 3G! I definitely notice the difference from when it goes from 2G up to the 3G speeds
http://www.htc.com/us/products/radar4g-tmobile?view=1-1&sort=0#tech-specs
Apparently. It says it does 2100/1900/1700/850
*T-Mobile only uses 1700/1900 bands. source
Interesting! I took my specs from the T-Mobile page which omits the UMTS 850/1900 band. Thanks for the correction.
The box clearly states GSM 850/900/1900/2100 AND HSPA/UMTS: 1700/1900/2100
AWS 1700 = T-Mobile, Wind, Mobilicity
UMTS 1900 = AT&T (although they use 850 extensively too), Rogers, Telus, etc
UMTS 2100 = Asia/Europe
My Radar picks up AT&T 3G. Not sure if UMTS 1900 band will be omnipresent on AT&T as a lot have been extended with HSPA 850 as well.
So, whereever you find UMTS 1900, you'll definitely catch AT&T 3G
Hope this helps.
So, will this work with the medianet plan?

YES!! Gets 6M downloads, 1.5M uploads.
So I read around that the hack for the Samsung Galaxy Note I717 to get the LTE 1700mhz frequency working on T-Mobile (U.S.) and Wind/Mobi (Canada) is available.
My question is, would this or any hacks work on any LTE1700mhz band phone to work on AWS carriers running on HSPA mode?
Like the HTC One X AT&T version for example..
3G Network HSDPA 850 / 1900 / 2100
4G Network LTE 700 MHz Class 17 / 1700 / 2100
which is the same specs as the Note in terms of bands it uses...
Anyone knows??

Hi all, I've tried doing a bit of research and have the folowing question.
How likely is it that one handset will cover all UK 4G frquencies in the future?
EE are launching 4G on the 1800MHz frequency which is supported by the I9305 and current iPhone 5 (see below). However the I9305 also supports the 800MHz and 2600MHz frequencies, from what I have found on the ofcom web site the auction of the new 4G spectrum only appears to include the 800MHz and 2600MHz frequencies? How will only two frequencies be split between O2, Vodafone and 3?
Does this mean that the I9305 will cover all UK networks on 4G in the future?
Samsung Galaxy S3 I9305 4G Network LTE 800MHz (Band 20)/ 1800MHz (Band 3) / 2600MHz (Band 7)
Apple iPhone 5 Current Uk model Model A1429 4G Network LTE 2100 MHz (Band 1) 1800 MHz (Band 3) 850 MHz (Band 5)
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.
