need help getting 4g - AT&T Samsung Galaxy S II Skyrocket SGH-I727

i just unlocked this phone and put it on t- mobile getting edge speeds and i am new to the rooting/unlocking/flashing things to my phone does anyone have a download link for a different radio that would get 4g speeds and would be able to help me flash them to my phone

Check your app settings.

i have checked all the settings from what i can find out it has to do with the phone being at&t radio and the radio not working on t-mobile 4g or even 3g for that matter

I tought it was the hardware in the phone that decides that this phone support the LTE (4G) frequencies :
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 1900 / 2100
4G Network LTE 700 MHz Class 17 / 1700 / 2100
but if this chan be shanged to : (4G Network LTE 700 MHz Class 17 / 1800 / 2600 )
By changing The ( flashing ) new radio..
Then Im interested
Pleas say something you out there that know this stuff

the skyrocket does support 4g lte that was the main feature over the galaxy s 2 the biggest thing is when you unlock this phone the radio program isnt set to read a different companies radio from what i have read and can understand so i was trying to flash a radio that would support t mobiles 4g connectivity

[Q] TMOUS Sensation 4G in Europe

I am travelling to Europe soon and can't really find out if the Sensation will fully work there. I am getting it SIM unlocked through TMOUS, but I am unsure about the actual bands it supports. I know it will work for standard GSM calling since where I am going 900 MHz is standard, but what about data? Will I at least be able to get 3G? Searched hi and low and couldn't find an answer to this anywhere. Thanks.
Paul
same boat
I'm in the same boat here. I leave for Ireland in the beginning of September, and hope to bring my T-Mobile Sensation (factory unlocked also). If anyone has any insight to this it would be greatly appreciated. 3G is a must now a days.
Go to gsmarena and look for the bands of the HTC Sensation and compare it with the Tmobile Sen 4g
just got back from spain/ibiza after a two week vacation:
i had a sim that ONLY did phone/sms and a friend had a sim that did data...but he kept complaining about the speed, so i'm assuming the speeds are edge-like. again, this was in ibiza and our choice of sims was limited...
HTH
gsmarena for htc sensations
that was a good idea hytl, looks like the tmobile version has two more frequencies on the HSDPA but everything else is the same. So our phones should work fine with 3G.
US Version
General 2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 900 / 1700 / 2100
HSDPA 850 / 1900 - For Bell (Canada)
European Version
General 2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 900 / 2100
Anyone know why the T-Mobile version doesn't pick up AT&T's 3G?(here in America) from what I've read online AT&T use's 850 and 1900, and gsmarena says it the T-Mobile Sensation can pick up those frequencies, but I dont get any 3G. actually I dont even get edge, I can just make phone calls and text, no data whats so ever on AT&T's network. dont know if i should start a new thread, but its confusing the hell out of me. Could it be a software lock? its not rooted or anything.

which 3g bands SGH-T959V has?

Hi all
I just bought new unlocked Samsung Galaxy S 4G (SGH-T959V) on the internet and before to talking to possible providers I got confused about its 3G bands. I've got two specs with different bands:
one says it has 1700/1900/2100 (e.g. see pdadb.net)
another says it has only 1700/2100.
How do I check which 3G bands my phone really has? Is there any way to check it using the phone itself? Like test software or something?
Thank you
From http://www.gsmarena.com/samsung_galaxy_s_4g-3719.php
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 1700 / 2100
Perhaps that is some of the confusion about bands; 1900 is also a GSM band.
T-Mobile, for better or worse, uses the AWS bands, which results in its handsets having a different set of requirements than other carriers.
I've used an AT&T SIM in my SGS4g and was able to get 3G, so I'm fairly positive the phone also has the 1900 HSPA band.
Wikipedia says T-Mobile has 1900 in both GSM and 3G
I dont know what bands they use but I use simple mobile unlimited 3g for $40 or unlimited 4g for $60....$20 sim with free activation. SimpleMobile uses tmobile network

Your in a bit of a bind then since you have the international version! Your phone might not have the right frequency support to get T-mobile 3g/4g until they complete their move of 3g to the 1900 band.
This is an excerpt from Anandtech Review
The International and T-Mobile One S differ in what UMTS bands are supported, as the International One S targets both Asia and Europe, while the T-Mobile version goes for the Americas. I’ve made a table with the pertinent information.
HTC One S - Network Support
GSM/EDGE Support 850 / 900 / 1800 / 1900 MHz
WCDMA Support
One S - International 850 / 900 / 2100 MHz
WCDMA Support
One S - T-Mobile 850 / 1700 / 1900 / 2100 MHz

You really need that 1700/1900 band for AWS 3g. However, t-mobile is currently moving 3g to the 1900 spectrum which should enable you to get 3g when it's done in your area.
Here is a map of current reported 1900 3g coverage. http://www.airportal.de/
Sorry to give you the bad news.

[Q] CM 10.2 ATT Skyrocket signal issue in Europe

I get my ATT Skyrocket from a friend last year.Phone is unlocked in Germany.I am facing a problems with signal after i install CyanogenMod 10.2,he is losing from time to time,people who calling me get message that i am unvailable,and i dont get every SMS message.I live in Bosnia and Herzegovina and a wonder is there any solutions for my problem.I am reading that can be phones radio/modem problem.Do i need to change phones baseband or radio/modem,does it supports CM 10.2 KitKat,is that causing my problems...Sorry on my bad english.Grateful.
Skyrocket has the following frequency bands:
2G NetworkGSM 850 / 900 / 1800 / 1900
3G NetworkHSDPA 850 / 1900 / 2100
4G NetworkLTE 700 MHz Class 17 / 1700 / 2100
After some searches I found 900/1800 MHz bands work for Bosnia so you're out of luck as far as your 3G or LTE.
You should lock the phone on 2G network and that should give you solid/uninterrupted signal.
Go to settings -> mobile networks -> Network operators
It will scan for a while keep the screen on until it finishes scanning the local networks. Choose your carrier from the list. Once it is accepted go back to Network Modes and change it to GSM.
Good luck
Please no PM's !

F350S uncompatible in UK

So i just bought a LG G PRO 2 checked it everything seemed to work fine
But then i realized the network connection drops every few mins and reconnects only to a G signal (2G)
so upon further investigation i discover that the band frequency on this model is CDMA eg. USA + Canada
To say im P*&^ed off is an understatement clearly the person who sold me this is aware and is now ignoring any contact i try to make with him
I have contacted LG to see if i can possible purchase a motherboard for model D837 or D838 as i see this is my only option to get the device working
Unless anyone here can advise otherwise
Once i go into the band selection screen and disable CDMA bands it seems to sustain a stable connection but only to a 2G network haven't been into a 4G area as of yet to test but it is completely incapable of connection to a 3G frequency within the uk which i will be connected to 80% of the time
not 100% with the F350 but the frequencies for it should be:
2G: GSM 850 / 900 / 1800 / 1900 MHz
3G: UMTS 2100 MHz
4G: LTE 850 / 1800 MHz
2G is fine, as UK uses 900/1800.
3G: all UK networks at 2100.
4G: only EE/3 use the 1800MHz frequency. no-one uses 850 in UK.
look around the forum for the secret menu and see if you need to enable 3G/4G manually. or do a manual firmware update.
,My Wife has an F320S (G2)and she can enable all Bands in the Hidden Menu and works fine in Europe in Austria.Network Operator is Three (HG3).
I think the F350S is the same.
Go to Dialer and tipe 5457#*350#
in Modem Settings can you aktivate all Bands what you need
I hope this works for you.
Thanks for the reply guys
There's loads of settings in the hidden menu
I cant see how changing anything in here will help as it is a CDMA device which means it physically does not have the necessary hardware to connect to a 3G network in the UK
As it uses a totally different technology than UMTS
Ive discovered at WCDMA is actually UMTS so i cant see why it doesn't work ?

Those are the default settings that the device is on so no joy with that thanks anyway
using my EE sim signal drops frequently using my daughters O2 sim it seems to sustain a connection but again only to 2G network
Clearly the problem is the WCDMA bands on the device are 850 / 1900 / 2100 while 2100 is used here 900 is the more widely available and thus incompatible with device
I think my only option is to sell it on but to who its no use to anyone in the UK really
