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.

Is there a way to tweak the Captivate radio to switch between the 850 MHz band and the 900 MHz band or turn it into a quad band UMTS handset that can be used as a world phone?
no. If you want the 900 band, get the Vibrant

What part of the world would I need 850 that doesn't have a carrier on one of the other 3 bands?
850 is where most iDen phones operate - hence you would need 850 in markets where the operator owns "850" and plans to re-deploy. Lower frequencies yield better coverage and iDen usage is declining.

North America! There are many places in the US and Canada where 850 MHZ UMTS is all that is available. AT&T is migrating UMTS from the 1900 band to the 850 band. Venezuela requires the 900 MHz band and Europe is moving in that direction as well. Right now I carry two handsets when away from home.

Hi guys,
I'm hoping someone can give me a for sure answer on this. I have a company we met at CES offering me some chinese cell phones. Basically they are an S4 knock off. I have definitely decided against selling these, but since I have a really old phone... I'm thinking about buying one for myself to play with.
I am currently on the t-Mobile network. Here is what their website says about "bands"
T-Mobile's UMTS network operates in Band IV, which uses 1700 MHz and 2100 MHz frequencies. Specifically, T-Mobile uses the 1700 MHz frequency to send information to cell sites and then uses the 2100 MHz frequency to receive information. A device must be able to use both frequencies to use T-Mobile's domestic UMTS network.
Most international UMTS networks operate in Band I, which uses the 2100 MHz frequency.

and here is the information about the phone:
MS mode: WCDMA/GSM
Frquency band: WCDMA 2100/850 (HSDPA) and GSM 850/900/1800/1900
Wireless transmission: 3G, WIFI 802.11b/g/n, Bluetooth 2.0, EDGE, HSDPA, HSUPA,

Everything sounds like it should work, but the concern is the 850/2100 on WCDMA. T-Mobile claims it uses 1700/2100.
For comparison, here is the t-Mobile Nexus 4
GSM:850, 900, 1800, 1900 MHz
UMTS: 850, 900, 1700/2100, 1900, 2100 MHz
Data:HSDPA+ (4G) 42.2 Mbit/s, HSUPA 5.76 Mbit/s, UMTS, EDGE, GPRS

I do understand that the chinese phone is only 3G, and the Nexus I compare to is 4G.
According to what I just read on another tmousa page (which agrees with your quote) their data (3g, 4g, and lte) all work on 1700/2100 as of this date of posting.
From your quote about your phone, it operates on gsm 1800/1900. That does not match with tmo.
I know you probably already figured this out, but I am searching on same subject, so others will follow.
Blessings!
Will this phone work with 3G speeds or only EDGE? Amazon Link.
From what I can gather, Claro frequencies are as follows:
CDMA 1xEV-DO in 800/1900 MHz
GSM/GPRS/EDGE in 850/1900 MHz
UMTS/HSDPA service in the 850 MHz band
This phone shows:
Network Frequency
- 2G: GSM 850/900/1800/1900Mhz
- 3G: WCDMA 850/2100Mhz
It doesn't show anything for UMTS, which a friend is insisting is needed for anything better than EDGE speeds.
Is this true? I am buying as a gift and the current phone the guy is using is capable of 3G speeds there. I wouldn't want to give him something slower, as he uses Whatsapp and stuff like that a lot.
Thanks for any help, I searched for about an hour before I gave up and decided to ask.
This may have been answered elsewhere, but I can't find it.
Just trying to understand something. I'm wondering if I can get a better signal with Tmobile if I use a phone that has a 1900 band on the 4G network. What I'm saying is, it looks like the Skyrocket doesn't support Band 2 for LTE on Tmobile's network. Is this correct? Does flashing your radio affect which bands you use for 3G vs 4G?
I'm supposedly "in the service area" for LTE on Tmobile, is why I ask, but I have never gotten a signal until I go closer to town. I'm within the edge of the "coverage" map. I realize those maps are optimistic. Have always used this phone here, but ATT works for people and the towers are in the same location as far as I know. Rural area.
Thanks for any help :fingers-crossed:
Skyrocket's bands are:
i727(r) freg's:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 1900 / 2100
4G Network LTE 700 MHz Class 17 / 1700 / 2100
Tmobile uses:
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

It looks like the Skyrocket doesn't use 1900 on LTE? Is that correct?
The reason I ask is because I'm on T-Mobile, and in my area, I can't get 4G inside some of the coverage map. I am assuming that I don't get Band 2 for T Mobile, which uses 1900 Mhz PCS. However, Tmobile also uses 1900 for 2G and 3G, which the Skyrocket supposedly supports. Am I missing something? Thanks. :good:

idk know the specific answer but our sister phone is the hercules t989 for use on tmobile and it does support lte and/or 4g
did u try the hercules t989 modems
