Anyone else notice in the notification bar that it constantly changes from H to 3G and back again? I am running the latest radio. Is their a fix for this?
This is normal behavior. If it states 3g your connection is idle and if it states h data is being sent.
Yep!
I'm using 3.6.3 and it shows 3G then when it uses data it changes to H.
Doesn't seem to affect it but it is slightly annoying.

That seems about right though it doesn't switch right away when data is being used. Thanks.

So I stumbled upon something interesting the other day while running a CSDI ROM. I noticed I was unable to use 3G data anymore even if I had full reception and my menu bar indicated a 3G signal was present. Funny thing is I can connect and use 2G just fine.
Since then I've tried wiping, flashing other roms, upgrading recovery, reformatting and partitioning my SD card but to no avail. I don't believe it to be a problem with T-Mobile's 3G network either (I've since called them an am awaiting any further help they could be).
I've made sure "T-Mobile" was selected under "Network operators" but that didn't seem to help. I know I can "use only 2G networks" but that would just be silly to not try and get my 3G up and running again.
Is anyone able to shed some light or have any input into this situation?
Current ROM: superD 1.11
HBOOT-1.33.0006
RADIO-2.22.23.02
8 GB Class 6 SD card
Thanks,

Try *#*#4636#*#* ,and then you can see information phone,there select "wcdma only".I have the same problem like you,the reason is that signal 3G no strenth enourgh and phone always change net between 2G and 3G.
I had no data for 3 or so hours, searched google's live twitter feed and others list data as well.

Thanks for your help, however after switching that setting, it worked for a little bit, then the data connection stopped functioning again. Even though it shows "3G" at the top with 3-4 bars, I simply keep losing the data connection whenever I access the internet.
This is very annoying...
I'm having a bizarre issue with my HTC Desire HD where the notification bar shows 4 bars of coverage (the max available) and the data connection shows 'H' (again, best possible), but the data connection often freezes/stalls/fails. Changing my data connection to 2G only fixes this issue and I get normal 2G connectivity with no issues. This is happening inside the building I work in (in central Edinburgh). I also experience this is other central edinburgh areas outside. However, further afield 3G works just fine.
Can anyone suggest what might be wrong? Alternatively, are there any tools which allow you to monitor the strength of data connection the phone is making? Or other diagnostic tools? Thanks!
I'm in Australia with a HTC Legend, currently running CM7, previously had Sense of course.. however I don't thin this problem is specific to Legend at all.
When I have 'Mobile Data' enabled and I'm in a good reception area, it will say '3G' or 'H' in the notification bar.
I'm not really sure what the difference is, I've heard maybe 3G is slower than H or used to save power etc. But they both occur with the same amount of reception.. either I get 3G/H or G/E if I'm at a place with really bad reception.
However the problem is, when it has '3G' showing at the top, the data speed isn't slower, but NO DATA AT ALL is transferred. Then it switches to 'H' and internet works.
The annoying thing is, it seems the switching between '3G' and 'H' is COMPLETELY RANDOM. I could be looking through market, browsing web, using maps, downloading, streaming youtube and it will continuously randomly switch between the two, turning internet off and on as it does. It's incredibly frustrating because even if I'm in an area with great reception and I know it's capable of fast transfer speeds, while it's stuck on '3G' mode I get no internet at all.
Does anyone know exactly why it does this, what it means or how I can make it to stop switching to '3G' and stay on 'H'? If it's the radio switching to 3G to save battery when it thinks internet isn't being used, I'd like to disable this because it does switch to 3G when I DO want to use the internet, or right in the middle of data being transferred.
Any help is greatly appreciated!
Can anyone provide any info? I'd really like to sort it out!
i think its depend on your provider, u cant always connect at H if your provider dont give u that signal

Its HSPA, what you get depends on your carrier's coverage area. A few cities in the US have them, such as Baltimore. When I flew to Minnesota I got 3G. As far as you not having a data connection on 3G, I believe if you're in an HSPA area you won't get data on 3G. I know I don't (I have a Galaxy S 4G). When you're in a 3G only area you should get data.

Hi All,
How do I make it so that my phone will not try and connect to the internet via 3G (the signal icon on the status bar has 3G written on it). Whenever my phone switches to 3G, internet doesnt work. this has been a problem for me here in Aus on multiple phones. While the icon says H, internet works awesome but the second it switches to 3G internet stops working until it switches back to H. It wouldnt be too bad, if it wasnt for the fact that the bloody thing switches back and forth every 5 seconds if Im in a good reception area, which is almost all the time.
Are you rooted/custom ROM? It sounds like it could be a poorly performing radio. Search for the radio/ril thread. You might find some answers there. You can switch your phone to 2G or 3G networks only, but the 3G option also includes H. So even if you left out the 2G you'd still suffer the same issues.
Hi, I have the Wifi + 3G version of the Galaxy Tab 2 10.1 P5110 and experiencing problems with the signal changing.
I connect to a website called Salesforce and whenever I input data my connection drops, I have noticed at the top the signal is constantly changing between 3G, H and H+ every 3 seconds. When connecting to this website through Wifi I have no problem.
I have changed options to just use 3G only but this still switches between the 3 network variances.
I have tried putting another web browser onto the tab and this had no effect.
I have double checked and triple checked the APN settings, deleted APNs, created new APNs and no luck.
I have also contacted my mobile data provider to see if they and just give me 3g access and no H or H+ but thats impossible on there side of things.
I currently have samsung stock 4.0.4 android software installed on the tablet.
Any ideas on what I can do to resolve this issue with the signal switching all the time?
This happened with me when i was in a place with bad coverage or inside a building. It cant maintain a stable connection so it switches to another.
When i got out of the building or moved to a place with better coverage the connection became stable at H+.
Hope this helps.
Also, if your tab is not locked to a provider try another provider.
