How compatible frequencies/bands with Tmobile? - AT&T Samsung Galaxy S II Skyrocket SGH-I727

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

[Q] Data usage/frequency (3G)

I got Nexus S on ATT and I have tried it with a TMobile SIM (got surprised because phone isn't locked...) but it works on 2G only.
I'm wondering if it will work properly (as 3G) in Europe. Does it cover 900 and 2100?
What is ATT's data frequency? Is it 2100?
thanks !
I'm gonna reply to my own topic: according with Wiki ATT uses 850 MHz and 1900 MHz for UMTS (3G) that means ATT (unlocked) phone will work as 2G in Europe (2100 MHz)
On the other hand, T-Mobile's frequencies are 1700 MHz (uplink) and 2100 MHz (downlink).
Does it mean a T-Mobile phone will be able to work properly on Europe's 3G networks (2100 MHz?

3G frequencies

I have a question about 3g frequencies among all carriers. If I have a device for example which supports these Frequencies
Device:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 1900 / 2100
And say I wanna use this device on T-mobile
T-Mobile USA 850/1900 for 2G/EDGE - 1700/1900 3G/HSPA
And I am only receiving EDGE on T-mobiles network is this because I am missing the 1700 frequency on my device? For all carriers listed 3g frequencies must the phone your using have both those frequencies to be able to get a 3g signal?

[Q] Samsung Galaxy s2 hd lte (SHV E120S) 3g does not work!!!!!!!!

Hello guys!
I just brought my Galaxy s2 hd lte which is known as SHV-E120s similar to att galxy s2 skyrocket in ATT.
It is unlock .
when i put my simcard, i always get G which is GPRS. This is so slow and it makes me crazy.
Thus, i look over google and find what my support 3g band which was.
2G Network: GSM 850/ 900 /1800/ 1900
3G Network: HSDPA 850/ 900/ 1900 /2100
HSDPA 900/ 2100
4G Network: LTE 800/ 1800 /2600
Also I look over T-mobile 3G frequency over google and found that
850MHz: GSM/GPRS/EDGE/UMTS/HSPA : 2G/3G
1900 MHz: GSM/GPRS/EDGE: 2G
1700/2100 MHz: UMTS/HSPA/HSPA+: 3G/4G
1900 MHz: UMTS/HSPA/HSPA+: 3g/4G
1700 / 2100 Mhz: LTE
Acoording to this chart. i know that i cannot use LTE.
However, i believe, it will support 3G which i have HSDPA 1900 and 2100 Mhz.
Based on m assumption, because of t mobile use weird signal AWS? thats why my phone does not work 3g?
i really want to solution for it. THE GSRM IS SO SLOW THAT I CANNOT EVEN POSE THINGS ON MY FACEBOOK.....
thank you.

UP !!!
Have exactly the same problem .... any solution to this ????
No it is not similar you're in the wrong subsection. Rocket HD is different. Also make sure your phone is unlocked and u need a different radio compatible with the T-Mobile frequencies

[Completed] Some help with bands please

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.

Does the Skyrocket have a 1900 LTE Band?

From the [REF] 1-stop Thread:
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
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:
Tmobile uses:
LTE Frequencies:
1700 MHz & 2100 MHz AWS band 4
1900 MHz PCS band 2 (in refarmed areas)
