Vibrant on ATT - Vibrant Q&A, Help & Troubleshooting

Hello im am using a vibrant unlocked on ATT with trigger 2.8.1 (which is pretty awesome stock, Ultra smooth) was wondering if anyone else is getting the H logo for data because i get the H logo and its pretty fast. Ocasionally i see the 3g logo flash for a split second but i mostly get an H logo. Whats the.difference between the H and 3g and am i really getting that H signal or is that just an illusion built into the rom?

I'd like to know as well

as far as i know, the H is 3.5G...so its faster than regular 3G

The "H" means you have the potential of a 7.2 mb download though I have never seen faster than 5.8mb on H.... still plenty fast

Help about 3G icon on Roms

Hi im a noob and im running the vibrant on the bionix-v rom and I cant seem to get the 3G icon instead of the H
How can I change that?
Sent from my SGH-T959 using XDA App
H is 3G it represents 3g and 3.5g the rom probably had this embedded when making it. to change you would need to push it in adb
Well I know that H is 3G but I want,it to say 3G and it changes but only when im on maps
Any ideas why?

AT&T HSPA (H) and UMTS (3G) coverage.

Hi All,
Ever since I debranded my phone when I first got it, I almost constantly get "H" rather than "3G" in my home. However, lately I have been getting a mixture of H and 3G. Is AT&T "downgrading" their network or something?! Knowing that they are crappy, I would not be surprised if they are actually starting to "cap" or "throttle" the speed of their network in some areas.
Anyone else experience a similar thing?
No they didn't. H comes in when you do something like go on the browser. Otherwise it just says 3g but its really h

That's the thing, even when I go on the browser it sometimes stays on 3G.
Afaik they are not throttling their service on the 3g end only when they light up the lte. Mine has been consistently h unless it's idle as someone suggested.

Sometimes. Not since switching from Rendeiros last rom to his latest. I would reboot then try it again with wat u were doing. That worked for me

Yep same here. 3g as I type this, obviously not idle... Been seeing it more lately but not all the time

Data verry slow after flashing any p500 rom

I have the T-Mobile optimus t running void#forever. No matter where I am, when I use data my 3g icon goes from 3g to H and is very slow. This doesn't happen on any rom made for the optimus t (or p509). This is the best rom I have found and don't want to change it, please help.

h = hsdpa
hsdpa is faster than 3g
Then why is it slower than 3g.

I fixed it, but totally forgot about this post. I had to go into the testing menu and change my bands to USA (or automatic). Then I had the speed I was meant to have.

My vibrant gets 4g?

From what i have researched, and i could be wrong there's not alot of info on this so i appologize in advance, the symbol for 4g is also an "H". I heard they have a vibrant 4g, ffc, 4g, etc., and i definitely do not have it. BUT my Samsung vibrant sometimes gets an "H" symbol when I'm in some areas. Concord NH doesn't get 4g but when im in a tmobile store i randomly get the h symbol and when I'm in Nashua i only get an h symbol. i pay 50 a month for unlimited data and 100 mgps at "4g" speeds. I just want to know if the T-Mobile Samsung galaxy s vibrant on firmware 2.1 stock, mine is on 2.3.7 cm7, gets or is able to get 4g on updated firmware. Thanks in advance for any help.

T-Mobile Samsung Vibrant does NOT have 4G hardware.
You are seeing an H because you are running a custom rom. On CM-7 and MiUi it displays an H, indicating something like 3.5G.
Oh ok thank you for the quick reply also one more question am i supposed to get 3g with T-Mobile unlimited data because i get a text saying 2g after 100mb limit is used and also on the my account app it says 2g. But in Nashua it says 3g on stock firmware, but the speeds are around 0.12mbps (internet speed app). I kind of want to know before i go to T-Mobile and waste time

I think that you are only going to get full "fast" speeds for the first 100 mb. After that it will still show 3G in the task bar but your speed will be throttled down to 2G speeds.
Alright thanks for the info mods can trash this if they want now

I assure you you're not getting 4G speeds. Your device does not have the hardware needed to receive these speeds. 4G and 3G is NOT software... so, not being 4G, you're definitely not getting it. It's just the ROM you're running. Despite icons, your phone is running as usual.

agreed. its all hardware, not software. on the vibrant, we are limited to a modem of HSPA+ 7. 4G is marketed as having a modem of HSPA+ 14 or higher.

3g connection?

I am not sure I have an issue or not in all honesty. I have flashed to the new baseband on my lg optimus t. I am using hephappys ics 9.1.4 but I never get a 3g icon. My connect speeds on mobile network show a h symbol and are about 2Meg down by 126 k upload. I am not really sure what I should see for a 3g connection.

Google and read more about 3G and H.
H stands for HSDPA.. means 3.5G basically faster than 3G.
Good to know. My stock rom must have just shown 3g instead.
I am surprised that updating the baseband has improved the signal as much as it did. I went from 2bars to 4 bars.
It's also nice to not have to flash a rom then flash the baseband fix.
