Hi
I just bought this device.
I am a noob, and don't know much.
Under info it says "SGH-T959"
I am under the impression that this is the 3G version (and not the 4G).
Am I right about this?
If I am right, and this is the 3G version, than something weird seems to happen: I just installed CynogenMod ROM and I see the "H" sign when surfing. Now isn't this the HSPA sign for TMobil's 4G speed?
So I am confused
Please help
Thanks!!!
Yes, the phone you have is 3G.
If memory serves, the H stands for HSDPA, which is what TMobile uses for 3G. 2G is shown as an E for EDGE. The stock Samsung ROM shows HSDPA as 3G while most custom ROMs change the 3G to an H. It means the same thing, though HSDPA is more correct.
What they should have done is used 2G for Edge and 3G for HSDPA, or E for Edge and H for HSDPA. But really, I'm just nitpicking now.
Thank you !!!!
I believe 3G = UMTS while 3.5G = HSDPA. Vibrant is actually benefiting from HSDPA, but simply is hardware limited to max data rate of 7.2 Mbits/s.

Hello,
I installed a ROM, its been a long time ago, so I don't remember which one it was... but I've noticed that my phone which used to show G on the top is now showing H at the same place.
My question is, is it just displaying H and running on 3G, or did the ROM disable my 3g, and put me on HSDPA network?
To make some things clear..
G = GPRS (normally when 3G or HSDPA is not available)
3G = UMTS (if available from operator)
H = HSDPA (upgrade of UMTS)
If HSDPA is available and you are connected to UMTS (this is setup first, normally) it will switch to HSDPA modus and will display a H.
The G and the 3G are always shown if covered by the place/network you are on. The H only shows up if the network/coverage of hsdpa is good enough AND your connected..
Atleast, that is the case here.
thanks for clearing that up...
excuse my inferior knowledge, but any idea why it was showing 3G before I installed the ROM, and it shows HSDPA after I installed it?

Well if your on AT&T their roms have HSDPA locked for no apparent reason but chefs here tend to enable it for you to give you a significant speed boost in up/downloading.
Hi
I have the Galaxy S2, when I turn on the use packet data and data roaming in the mobile network settings, an icon H+ starts flashing on the top of the display with two little arrows.
1. What does it mean? Is the phone downloading data from the cellular network?
2. What is: packet data and data roaming? What's the difference between the two?
Many Thanks.
Hi,
The icon itself means that you are connected to the data network of your cellular provider.
The icon can look like one of the following:
G - 2nd (or 2.5) generation connection
3G - 3rd generation coonection
H - 3.5 generation connection
H+ - 4th generation connection. This does not mean your provider actually support 4th generation data rates.
When the little arrows are gray - No data is being sent/received. When they are colored it means your phone is sending/receiving data.
Roaming means that you are connected to a "foreign" cellular provider (not the one you are paying to).
Data roaming means that you allow your phone to use data connection when you are roaming.
Using data connection while roaming is extremely expensive and it is highly recommended not to do so.
Hope I got it all covered for you

Thank you for clearing this for me.

well I did my digging and got some more accurate figures in addition to the above
G is GPRS 86kbps
E is EDGE 236kbps
3G is UMTS 386kbps
H is HSDPA 3.2Mbps
H+ is HSPA 7.2Mbps
H+ is too for HSPA+ for 14.4Mbps or 21.1Mbps
(noteH and H+ are the so called 3.5G
and the new comer:
4G ( LTE technology) is 100-300 Mbps ( the iphone5 is said to be on 100Mbps)
some phones don't show H or H+ , they just show 3G for UMTS, HSDPA, HSPA, HSPA+
only G or E means it's on 2G, - that is you are not in 3G coverage
PS on my Vodafone, using speedtest.net app i get on H+ 7.12 Mbps... ( aka 0.89 MB/s)
Period

Is there a different icon for DC-HSDPA, or is it 'lumped' into H+?
The standard should theoretically allow up to 84Mbps with MIMO, but my phone only supports up to 42Mbps.
KPN in NL has it rolled out, but I've never been able to confirm if I'm on DC-HSDPA. Using Network Signal Info android app, the fastest I've connected is HSPA+ at 21.6Mbps.
hello seniors, please someone help my phone e120l network not connect to "H" only G/3G connected..how to fix this problem? im already updated to 4.1.2 jelly bean rooted+cwm recovery..

Did you connect with stock installed firmware to H or not?
Before this im using rooted rom from Vietnam dev.. Its enabled H on my status bar.. But after a month using thus phone there is no H available.. After that i reflash stock rom then 3G came out from status bar.. No H anymore.. Download speed also decreased via 3G..

Hi, I have my optimus one for half a year. After i upgraded the software to 2.3.3 the 3g doesn`t worked(there is just a H) What can I do to solve this problem?
PS: The update has come with Vodafone Romania and i am on Orange Romania.
Check if the /system/etc/apns-conf.xml contains entries for Orange Romania. If not, download CyanogenMod apns-conf.xml
Otherwise try to flash the old baseband.
Is data working, but you're afraid you aren't getting 3G speeds? This is from the CyanogenMod FAQ:
Why do I sometimes see an 'H' for the network mode?
H = HSDPA mode (fastest)
3G = UMTS mode
E = EDGE mode
G = GPRS mode (slowest)
NOTE: Almost all 3G devices support HSDPA mode, however most stock firmware only indicates "3G" regardless of whether the device is in HSPDA or UMTS mode. CyanognenMod uses "H" to differentiates between the two modes. Note that HSDPA is not 4G, it is merely an extension of the 3G standard and is therefore only slightly faster than true 3G.

Are you sure that H is fastest then the 3G? The speed is not so fast as it was with 3g.

So what? Did you read what I already posted?
"however most stock firmware only indicates '3G' regardless of whether the device is in HSPDA or UMTS mode"
Some stock firmware shows an "H," and some does not. Guess which you have.
Thanks for help. I will try with CM7 to see what is hapenning.
It's weird. I have an Atrix and a new GSII. At home my Atrix shows HSPA and my GSII shows HSDPA. Isn't HSPA "4G" and HSDPA 3G?

That's what I thought too, and I'm also showing HSDPA... hmmm... but the upload speeds are HSPA+ so it can't be right.
I thought both 3G and "4"G could be called HSPA. High Speed Packet Access.
Doesn't the D stand for download. I thought HSUPA (U for upload) was the feature that got all the publicity with the Atrix, as it wasn't activated at launch.
I am sitting on H+ according to my status but in about it says UMTS, which I thought was 3G. My HTC 8525 ran on UMTS 4 years ago.

I think in the about settings HSPA means HSPA+ while HSDPA means the slower standard. I think it is probably a bug. My Atrix could distinguish between HSPA and HSDPA in the about settings. In areas without 4G it would read UMTS or HSDPA while in advanced backhaul areas it would read HSPA. On The GSII it seems to be messed up. I never saw HSPA.

Mine is acting the same way my Infuse was. It never seems accurate. Obviously if you pass the 0.33mbps range your HSUPA is enabled. That's about all we really know for sure, hehe
Phone status display frequently is broken in the framework and not reporting correctly.
For example, the Infuse would report UMTS when in an HSPA+ mode...

I'd imagine the marketing\disguising one technology as another and not being forthcoming about where has "enhanced backhaul" nor defining what "enhanced backhaul" even is in terms of speed, likely doesn't help things either ;-)
hspa and hsdpa are both 3.5G at best

Dial *#0011# on your phone. The screen will show what exactly is your phone using. So far, I have yet seen 'HSPA+ used' display anything other than 0.
New I-9300 owner here on AT&T. I noticed today that my phone says HSDPA in network settings. Is this the same thing as HSPA+? Do I need to change some settings someplace? I am temporarily in small town, so hard to tell from speed tests -- best I have seen so far is 2704 down.
Thanks for your help!
Another thing I can't figure out is how to choose an APN. I set up one to match my GS2, but after I select it, it switches itself back to one AT&T set up. ???
There is no such thing as HSPA in technology - only HSUPA (HSPA Upload) and HSDPA (HSPA Download) - which are cooperative but not necessary for each other.
Sounds as if the Apn failed, so it tries the other ones. An easy method is to delete the other APN's and hope it understands what you want

I don't think your statement that "there is no such thing as HSPA" is correct.
The Samsung PDF user manual for the I747 lists both HSPA and HSPA+ where it explains the 4G icons, and I have personally seen both HSPA:11 and HSPAP:15 on my device by looking at Status > Mobile network type.

I know this is an older thread, but I was just reading this support document yesterday:
http://support.t-mobile.com/docs/DOC-4987
Data services
HSPA (high speed packet access) is actually two different components. HSDPA (downlink) and HSUPA (uplink). Like our 3G voice services, HSPA is WCDMA based, so the same improvements to efficiency and bandwidth are seen here.
HSPA has a maximum download speed of 14 Mbps.
Customers on 3G can use voice and data services simultaneously.

This page provides an overview of HSPA+, which is the technology T-Mobile uses for our 4G network.
HSPA+ is an enhancement of T-Mobile's 3G HSPA technology.
It offers data faster speeds but requires the necessary backhaul is in place (backhaul refers to the pipe that connects our towers to the Internet).
All 3G sites are already using HSPA+ technology but they are referred to as 3G until that backhaul is there to support the faster speeds.

Dunno.
My phone has (in order of speed)
3G
H (HSDPA)
H+ (HSPA+)
It doesn't do 2G on my network.
So I assume that H is actually just HSPA.
I've seen the following marks on my S3 (International 16GB, Stock 4.1.2).
G
E
3G
H
H+
G is barely usable. Like 0.02mb down, ping over 1000.

If you really want to know these will explain it all in full
HSPA+
HSDPA
HSDPA download speeds up to 42mbps where HSPA+ has download speeds up to 337mbps with release 11, 168mbps with earlier release 7
E - edge = slowest
G - gprs = slow
3G = "normal" speeds
H - HSDPA = Faster download speeds
H+ - HSPA+ = Fastest speed on the S3
4G = 3 times as fast as 3G, only on LTE version
