Not quite sure what you mean, but UMTS 1900 is already there on the international version, same for the 1900 GSM frequency.
Quad band GSM 850/900/1800/1900
Quad band UMTS 850/900/1900/2100
I guess OP's phone is locked on certain network and he wants to unlock it or the Korean version doesn't have 1900 frequency.

Hi friend..
well as i can read on Wikip.edia, Telus and Bell Mobility work on HSPA 850 & 1900 MHz. At&T, work on HSPA 850 & 1900 MHz and also on GSM 850 & 1900 MHz.
In the specifications of Mozart by HTC site you can see:
HSPA/WCDMA: 900/2100 MHz
GSM: 850/900/1800/1900 MHz
so i think Mozart can work good only on AT&T that have GSM protocol.... but i saw also on Canadian HTC site and i found that HCT provide HTC Surround branded Telus... i search for specifications and i see:
UMTS/HSPA – 850/1900/2100Mhz
Quad-band GSM/EDGE 850/900/1800/1900Mhz
..practically the same!
I cannot try that cause im in Italy... but i think it work good too.
Hope i helped you a bit! SEE YAA

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
mike1986 lays out the differences in a chart http://forum.xda-developers.com/showthread.php?t=2223236
Come on dude there has to be a million threads on this one topic, please search before posting as per the rules

A radio doesn't add bands to your device automatically

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
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.
