Signal Changing 3G H H+ - Galaxy Tab 2 Q&A, Help & Troubleshooting

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.

MyTouch 3G Unable to Access 3G Network

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...

Sending it back to Samsung or your carrier is the best solution if you do not know what to do.

Prevent 3G data connection

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.

3G data disable while on roaming

Hello,
I know there is a thread for this in Galaxy Note section, but i feel i need to share this for OPO community.
I'm using OPO v33 rom. I live in Mumbai and have a 3G vodafone postpaid corporate connection.
Recently i have been to my native mysore on few occasions, and everytime i have seen the 3G data getting disabled even when the data connection settings are enable on roaming.
I never faced this issue on my nokia lumia 920 which perfectly latched onto roaming and 3G data was available.
On roaming, with OPO, the data gets disabled and i dont get a specific "E" or "H" sign with + noticafion.
I only have the signal bars with small R icon on top of the bar.
Please let me know if there is a workaround for this.
I have also seen this issue on v25 rom aswell.
Note: i have tried setting connectivity to automatic in mobile networks.. and also tried to select the specific Vodafone network. both didnt solve this issue.
Another interesting thing while on roaming: my nokia 920 recognised 2 networks for vodafone.. one with 2G, 3G and another with only 2G. and i could select the first one .. and 3G was getting enabled without any issues.
i think that E and H as well as H+ is only something you can geti n your own country. When roaming, it's always the default for that service prodiver in the country that you will get.

You said your rom is not rooted? That probably means the default network settings for your phone is LTE/3G/2G. That option will look for the best signal you have in your current location, then it will choose that data network i.e., EDGE .
It seems like your 4g/LTE signal is weak on your vicinity Perhaps, if you could force LTE (by rooting and installing Advance Signal Status app from Playstore [Device Info >Set Preferred Network Type > LTE only) you can have at least lte reception. Unless, 4g is not available in your area
Try going outside your house, and find open spot and see if your device was able to detect it.
Just let me know if you still have some concerns. Cheers!

Same problem for me. Same galaxy s6 model and same original android version 5.1.1 (g920fxxu3q0kn)
From a couple of days it doesn't connect on lte. But the big problem is that if I choose lte/3g/2g it doesn't connect neither in 3g. I have to force it to 3g only to let the device connect back to internet.
I don't know why but when I came back home, if I switch back on lte/3g/2g, it connect back again on 3g (no lte in my home area)
I'm not sure if it is involved with transit in/out wifi spot or some kind of lte cells. I will try other tests next days
I fear it could be a bad bug
