Ok this has been bugging me.
My GS2, whether stock, or currently with UnNamed 1.3.2, the phone always says UMTS under Mobile Network Type under Status and I am confused as to why?
I live in the Northern VA market and all around here is solid HSPA coverage. I actually even live in an LTE area as well. But any where I go around here, including where I work, it always shows UMTS. Where I work (AT&T) our two display GS2's also always show UMTS. Our other phones show HSPA like they should. I also have an Atrix which properly shows HSPA.
So I never really know what network I am really on. I don't know whether I am really on HSPA and it's just displaying wrong, or I am actually on UMTS.
Anyone have a clue what is going on?
The framework lies and displays everything as UMTS. Simple as that.
It was funny - on the Infuse, the display rules seemed to be:
UMTS = UMTS
HSDPA = HSPA
HSPA+ = UMTS
Well it appears as if the GS2 is having the same problem as the Infuse then. Do you think it is inherent to Samsung Phones?
Also do you know if there is a patch to correct it to properly display the network?
I am using UnNamed 1.3.2 and I noticed in his thread a CWM flashable add-on called "Show true connection status in the status bar".
I know that won't really correct the issue, but I haven't tried that add-on yet. Do ya think that would work give a proper display, or would it be reading it from the same place that is having the issue?
*EDIT*
Oh I forgot to mention, that it appears that the Skyrocket doesn't suffer from this issue. Our display models at work properly display HSPA like they should.
Unnamed will differentiate between UMTS (3G) and H+ in the status bar.
Not sure about H vs. H+
Edit: Probably related to the fact that AT&T stock ROMs lie and always display H+ for any network mode other than GPRS and EDGE.
It idles in UMTS and switches to HSPA when data is in use. What your status bar shows is completely dependent on what the rom developer configured it to be.
I have similar problem. I wish to use edge to have better signal, but it is always UMTS...Usinig UNNAMED 2.2.1. There is not a option to choose network type. Anyone know what to do?
B.T.W. *#*#4636#*#*---->Phone information---->GSM only doesn't work. It won't save the option.

But what's curious is the SkyRocket properly displays HSPA though. Whether it's idle or not it displays it correctly. The code can't be all that much different being as the Skyrocket isn't that much different of a device.
Also as far as displaying it on the status bar, the mod that you can get for UnNamed for the true connection on the status bar, is it reading it right from the network or just from the settings? My point is if the phone is showing UMTS, wouldn't the mod on the status bar still show it cause that is what the phone is showing? Or would it be correct?
Most hellraised Rom will have what you are looking for

Does anyone think or know why or why not we can flash the radio from the G2 to work on the vibrant to get the HSPA+ network connections. or is this a hardware thing? im not a dev but wouldnt mind learing so i can contribute too.
it is a hardware thing. the vibrant can get hspa connections but not hspa+. hspa maxes out at 7.2Mbits/s though, so that's still pretty good.
How would we be able to get hspa working? I think my touch pro2 was on hspa. I always had the H logo in the tool bar.

This same question has passed my mind as well. More often then not I notice in the phone status that the signal is UTMS, on the rare occasion is may say hsdpa. So i wouldn't be surprised if in the radio settings, utms is the preferred signal type.
we already have hspa. hspa+ is what the g2 has. hspa is just 3g...
From past experience with all of my previous smart phones the radio firmware upgrade is hardware specific.....So a Samsung radio will not work with HTC(G2) firmware.
for t-mobile, when you're on HSPA or UMTS, it just uses the 3G logo on the notification bar.
you can check at settings->about phone -> status to see what mobile network type you are on. mine says HSDPA right now, but when i'm at home, it usually says HSPA.
when they update your cell site with the HSPA+ cell, you will probably get an increase in speed because they will probably upgrade the internet connection to the cell to support HSPA+ speeds which means you get up to 7.2Mb/s. I think someone said earlier that most 3G sites only have two T1 lines as the backhaul, meaning you will probably get max 1.5Mb/s in a speed test.
Hardware thing. MIP
HSPA 7.2 is good enough for me and when HSPA+ rolls out in my area I ought to get closer to that theoretical speed more often. I've seen speeds like 5.9 Mbps on Speedtest.net when I'm near a regular HSPA tower.
I do wish we could mod the icon to display an "H" on HSPA connections like the G2 (G2 shows an "H" for regular HSPA as well as HSPA+). I remember running Klick Hero on my G1 almost a year ago, and getting the H icon from time to time on that old thing!
You can confirm you are on HSPA with the Mobile Signal Widget.
Itll show h on 2.2

The reason you cannot flash the G2 radio to get HSPA+ on the Vibrant is because the Vibrant DOES NOT HAVE A HSPA+ RADIO. Flashing the radio/modem software onto the Vibrant will not help and will probably damage your handset.
Adding software to the phone to use hardware it does not physically have is pointless.

You don't do anything to "get HSPA working", because it already works. If the cell site your handset is connected to is HSPA, then that is what your handset will connect with.
Just because the icon in the notification bar says "3G", this does not mean that you are not connected to a HS(D)PA network. Check "Settings > About phone > Status > Mobile network type" to check which type of network you are connected to. Mine currently says "HSDPA", but I have a "3G" icon in the notification bar.
Does anybody think its possible to take a baseband chip from the Epic 4g, and solder it into the Vibrant to get it to work with Sprint's WiMax network?
Only way I see that happening is of you mod the phones hardware then mod the software drivers to make it work...it can be done but is a huge pain in the butt....I use to mod our sat phones and radios over in iraq to bump signal for direct calls...the hardware side is easy little patch work needed....software side to make it work is where the work would really come in...mod for the kern...then drivers...then fixing all dependency issues for the radio...then last part is the battery issue...you would have to find a radio that wouldn't eat like it was at an all you can eat dollar dinner....but if you are into hardcore mods keep everyone posted...lol

Not without a ton of programing knowledge.
i would venture to guess no, because more than the baseband chip would probably need to be included. you'd probably some of the receivers as well. At the very least, the chip marked wimax power amplifier.. http://www.chipworks.com/samsung-epic-4g.aspx
why would you want to do that anyways? the phone isn't designed to support two baseband chips so you probably wouldn't have any way of having both tmo and wimax. might as well just buy both phones

The shipped ROM on the Vibrant does not display an "H" for HS(D)PA connections ever. It will only show "G" for GPRS, "E" for EDGE and "3G" for UMTS, HSDPA and HSPA.
Try phono which shows real time signal. I was able to find the right spot for signal at work.

http://en.wikipedia.org/wiki/Umts - when the icon shows 3G this is what it shows
http://en.wikipedia.org/wiki/HSPDA - when the icon shows H
HSPDA is able to provide faster speeds, but I believe it's highly dependent on how strong your signal is
Not sure myself, but if you're on Tmobile or ATT it pribably stands for HSDPA. 3G would mean WCDMA I believe.
Sent from my Vibrant using XDA App, Bionix-v 1.21
Long story short... it depends on how the ROM has been programmed to display what protocol your phone is using for data traffic.
3G just means regular UMTS 3G data
H means that it is is using HSPA, a faster protocol for UMTS 3G.
It doesn't mean that you're taking advantage of the faster speeds... that is dependent upon a slew of other factors.
Just to clear some things up. 3G is an all encompassing term, that INCLUDES the following technologies:
UMTS
HS(D/U)PA(+)
W-CDMA
EV-DO Rev 0/A/B
LTE
WiMax
As noted in the post immediately above me, the symbol it shows, depends on how the rom was customised to show each icon for the corresponding protocol.
If you don't believe me, that's cool, but go look at the ITU declinations on what is and is not 3g. There is no 4G CDMA technology. Pure CDMA is dead in the long run. All the current 3G GSM technologies, use the WCDMA or OFDMA air interface.
OFDM is not 3G

This is false. WiMax uses OFDM and LTE uses OFDMA (the same, but for multi-user as opposed to single). WiMax as 802.16e is NOT 4g. Neither is anything currently available and anything being deployed in the next 2-3 years.
I didn't say it was 4G. I said that OFDM was not 3G.
It isn't. Taking the broad view, its pretty clear to me that code div mult access is what differentiates 3G from its predecessors.
With 4G it will be orthogonal frequency
Here's a mathematical formula that pertains to all Vibrant ROMS that use an H and/or 3G
3G = H
The answer is, there is no difference except for the way they look. Both are really only using 3g.
The phone switches from hsdpa to umts back and forth all day according to how you use the internet. It automatically switches from hsdpa to umts when it is not browsing the web. That is-- if you live in an area with hsdpa. In which case it would stay on umts all day. Which would make your battery pretty happy. My battery hates hsdpa

This is false. Your phone jumps on the preferred network. Usually, unless you have specified, it sits on the fastest preferred network available. As such, battery consumption improves when you disable 3g (which is HSPA AND UMTS).

If it's not 3g then what is it? OFDM is used on both current 3g and future 4g (LTE-Advanced) systems.

hi there,
I believe what you say and if it is just a matter in which the ROM is programmed, why does my stupid S3 still switches from H+ to 3g?
I dont know and I cant tell if either of the two is faster than the other, but it is annyoing the constant switching
Thanks

H+ = HSPA+ = 3g. There are different names for the different 3g evolutions and technologies, but they are still 3g. It keeps hopping between the networks because you're unfortunately in an area with bad coverage for the faster network.
Hey, I have an USA T-Mobile Vibrant.
It is rooted and running the Vibrant edition of Darky's 9.3 Final ROM.
I am also using the latest overstock kernal and the honeycomb 2.0 theme from the I9000 forums.
Enough background info. This isn't really a problem as much as my curiosity.
My phone almost constantly is switching back and forth between 3G (UMTS) and H (HSDPA) on my data connection.
It doesn't seem to affect battery life or service too much (though H might be faster), so I'm not worried; but does anyone know what the deal is with this?
Thanks ahead of time!!!

Mine has been doing this lately as well. It's only been happening since I installed my current ROM (Trigger 2.7).
Noticed this just now as well...might have something to do with the mods to show H or 3G.
I wonder if it has anything to do with signal strength. I know that shouldn't make a difference but I can't think of any other reason.

I would agree, but I went to my settings/ phone info/ signal page and the reason it was changing was because it was physically switching between UMTS and HSDPA.
Why? I have no idea.
I do live in a T-Mobile 4G enabled area, though I am not on their so called "4G plan".
I did notice that it did not have this switching problem on Bionix Frost-u2.
So, if anyone has some insight, please help us all understand

I was just watching my signal strength change and it doesn't seemed tied to the change from 3G to H.
For example, it would be around 67dBm and be on UMTS. Raise to up to around 75dBm and be on UMTS. Then it would switch to HSDPA and still be at 75dBm or sometimes lower down to 69-72dBm and still be on HSDPA.
So with that type of cross-over stats, I would be skeptical of that solution.
HSDPA is a temporary data link. If it was on continously the phone would have very poor battery life.
When network server has a data packet for your phone it 'pages' up your HSDPA capability. Your phone can also request HSPA to initiate a data transmission.
The HSPA paging process is similar to receiving and initiating a voice call.
If no more packets have qued at their server or received from your phone after some period of time it will revert to normal 3G battery saver cycling. It has to be re-paged up to reinitiate HSPA data link. The wake up HSPA function does add some initial delay.
So is there a way to force it to stay on HSPA while tethered, for example? (Or always)
Ever since I've transferred to AT&T I've had laggy data issues. I finally rooted/flashed to AOKP, and while trying to address the issues of no APNs appearing or saving and no signal status in the status bar, I've come to find both AT&T and T-Mobile as Available Networks under some network setting. Am I chasing ghosts here, or is there something actually up?
EDIT: So I really need help troubleshooting the issue. I'll logcat, dump, or whatever necessary. I've been in many cities/areas and this problem persists: if I haven't used data or the phone hasn't been backgrounding traffic, it'll take anywhere from 5 to 30 seconds before a connection is made when I try to access an internet-related function on my phone (even though 3G/H is displayed in the status bar). Out of shear frustration (this has been happening since I got the phone, under stock ROMs and now under AOKP), I tried messing with *#*#info#*#*. I changed WCDMA-preferred to WCDMA-only -- no improvement. Oddly, I also tried GSM-only. Well, great improvement! Even though I only have E, there is absolutely no latency in waiting for a connection -- so pages and other data end up loading faster on Edge than 3G !
I have absolutely no idea why my phone takes forever to make a connection. Under 3G, I see only but a few upstream network activity blips (even under full bars) for as much as 30 seconds, before there is any downstream activity (and when it comes, it comes). Can anyone help???
P.S.: I'm going to try using a friend's SIM later for comparison.

The phone displays 3G because thats what it is... then when data is being processed, it shows H because its using the "what AT&T calls 4G but its really HSPA" side of the network. For just standby time with no data, its going to show 3G because HSDPA is traffic, not standby.

Well that's strange. I'm used to phones displaying what network-level they are capable of. So why would it not just display H for HSPA+ when HSPA+ service is available, instead of only displaying under traffic.
I'm going to go ahead an edit this thread to help troubleshoot what I think to be the main issue.
After some trials I see that the network indicator switches back and forth between 3G and H a few tines before making the connection and transmitting data. Hmmm...
Basically, "4G" will eat your battery alive so the phone idles at 3G and jumps to H+ only when you use data. If you were on a "stock" ATT rom it would always read H+, but this is technically false since when its idle the phone sits in 3G. CM9 and AOKP accurately display it which is why you see the switch.

I have a HTC Amaze for a phone and the Galaxy S2 is my media player. Sometimes, when I don't feel like carrying around two devices, I put my T-Mobile SIM in the galaxy and use it as my phone. I must say, Edge is not as slow as I remember it being. Maybe speed is contingent on network traffic. If thats the case, instead of using crowded "faux G" networks, I may defer to Edge to save battery life and get good dl/ul rates.
My phone does the same thing. I noticed it sometime ago. When idle 3g. Internet I get H+. This is with both Shostock2 and Phone Bricker. I was curious to know too but just blew it off because it really doesnt make any difference to me as long as Im getting decent speeds. Im not even with ATT anymore. Went with Straight Talk. Which uses ATT towers. Cant beat the price!!
They don't have the correct apns, but that symbol problem is because the phone doesn't use hspa+ passively, only actively. It causes some lag when downloading, but it is faster fit large data. But your problem is due to a supposed imei range with bad modems. Rehash stick, fix the triangle, and return it.

Can recommend a radio for this phone? It was originally for Rogers, unlocked, rooted, and I'm using blackstar jelly bean.
At first i used the SGH-T989D TLMC4 radio, only worked well downtown Mississauga.
Right now I'm using the Blaze 4G UVMB1, radio, works a lot better but I live on the edge of coverage so it's spotty at best when I am at home.
So if you have an experience, please give me a recommendation.
This is my exact set up man, good to see someone on this site on the same boat. I've noticed that the T98 works better on 4.2 for some reason. I get really poor reception in my room (switches from mobilicity to CND roaming allot). But on 4.2 I was able to make calls and send text more reliably. Try "kid blaze" though it doesn't show any signal bars but it connects pretty well
