[Q] vzw user please help with me 3g data drop problem. - Galaxy Tab Q&A, Help & Troubleshooting

Hello, I am using Samsung galaxy tab. I am experiencing a problem relates to Verizon Wireless 3G. Whenever i use the browsing over the internet, or tethering with my other devices such as pc and android os. The 3G data somehow dropped ( the 3G local will disappear). I tried to click and un-click airplane mode, and data setting, but the 3G will not turn back On unless i reboot the tablet. I already bring to the Verizon Store, they told me only can do a hard reset. I don't think that will help. I am writing on xda to see if any Verizon wireless Samsung tab user experienced such problem, and do you have any suggestion and solution will help me a lot. Thank you so much.
My tablet running 2.3.5 rooted stock roms.

Data not working

I have an HD7 and intermittently I will try and use my phone, I will have perfectly fine signal yet none of my apps email/youtube/facebook/internet explorer/bing search can connect to the web. Signal will be be fine yet they will pull no data.
If I restart the phone it will work again for a few hours and then randomly happen again. Personally I am getting just a little annoyed with having to constantly restart the phone 5-6 times a day. Is anyone else experiencing this problem?
Just so you guys know I am not trying to troll or dog the OS, merely wondering if I have a faulty unit or if this is an OS issue.

so sorry, but do u have data connection with your current sim/plan????
my last plan did not have data plan on it and the phone did not work until i sudscribed the data...
and u cant set up phone with out 3G data plan...
I faced the same trouble few days ago. I dont have Wifi, cannot download "connection setup", but i flash a Singtel Rom (My HD7 is T-mobile):
RUU_Schubert_hTC_Asia_SEA_WWE_1.57.728.02_Radio_5.52.09.16_22.33a.50.10_Signed
Then it work, data connection is fine.
For anyone who comes from an Android phone with data service, check with T-Mobile to see if the service is combined or separate. T-Mobile did have two separate data services, one for WinMo and another for Android, and they would not work with the other phone system. This is how it was with my service and T-Mobile combined them for me so that my data service now works with either system.

Yeah I have data on my plan. Data will work fine for hours but then I will put it down while doing something use it again and no data. If I reset it then it works again for a short while until it happens again.

Hi Jason,
Was it difficult to flash your T-Mobile (USA?) HTC HD7 with the above ROM? Did you gain anything else over the original T-Mobile Rom? I presume it will get rid of the T-Mobile splash screen! Cheers.
Running into the same problem as the OP with my Mrs. HD7. Took hers for the last little while and I can do a reset and access about 3 pages worth of info or updates and then it drops. Tried manual apn configuration, automatic and htc connection setup and no luck. This is at all times of the day in all locations so it is not network based or sim card based as I went to the t mobile store and stuck in the sim and was able to access the network with zero problems on all demo phones. Customer care finally agreed to a warranty replacement after some help from a store rep. They would not allow an in store exchange unfortunately.
What network are you with? I get data issues on giffgaff quite a lot. But a reset does nothing about it - it seems to be related to which cell tower I'm bouncing off and whether it feels like giving me data connection (even though signal strength is maxed out!).
I have this same problem, personally ive had it with my HD2. A quick fix for this is turning on and off airplane mode instead off turing off and on your device.

[Q] Data Connection After Restore

Hey folks. I fixed my phone last night, and know how to get through the scary stuff. Now I'm having a small issue with my wireless data connection.
I'm able to use voice and messaging, and my wifi allows me to use the web. Unfortunately, I can't do anything web-based on the Rogers network.
I'm hoping there's a way to sort this out in the settings, but if not, I'm reflashing soon anyhow. Thanks for any help.
find out what your APN should be for rogers.
After switching to Firefly 3 everything kicked in perfectly. Thanks.

[Q] Wifi disconnects data network after gingerbread update (i9000m)

Used Odin to update to gingerbread from froyo on my i9000m the other day. Theres no service here at home unless I put the phone on the bathroom windowsill, so I didn't notice until today when I went to work that I wasn't getting any data network connection. Could make and receive calls fine, wifi works, but no data, so no browsing or facebook or any apps that require it. I called bell and they came to the conclusion that I have to send the phone in for repairs. Thats a absolute last resort, so I tried another factory reset, this time from the recovery menu. The first time, during set up I enabled wifi, this time on a hunch I did not, and it worked. Also note that the first time, the network connected for a split second before disconnecting again. Anyways, I was getting 3g fine, then I tried wifi, and it disconnected again. Turn off wifi, data comes back. Whats up with this?
Did you set your APN? Go
Settings > Wireless and Network > Mobile Network > APN Names
Then hit menu and add a new APN if none are there. If one is there, it's named something like 'browser' (at least that's what mine is called on my Bell i9000m) and I'm wrong. But I had this problem, and this is how I solved it. You can find the APN settings for your network by google-ing "[Provider] APN Settings]", and if you're on bell you can find them here:
http://support.bell.ca/en-on/Mobili..._Nexus_One_for_the_Bell_Mobility_HSPA_network
It says Nexus One but it works for all phones on bell.
settings are exactly as depicted on the bell site, except the apn was called browser instead of bell. changed that, same thing. other suggestions?
Can you tell me the version of gingerbread you're on, where you got the files, any mods to the firmware like pre rooting?
Sent from my GT-I9000M using XDA App
2.3.3, downloaded from here, no mods.
Alright, so totally stock. What's the version code? It should be UGKG3. Have you tried forcing a kies update with a registry hack? Was it one PDA when you flashed it or 3 files?
Sent from my GT-I9000M using XDA App
Yes, its UGKG3. I flashed with the PDA, PHONE and CSC files. I dont really know what you are talking about with regards to forcing a kies update, if you could explain I'd try it out
This has always happened to me, on Eclair, on Froyo, and now on Gingerbread. Whenever my Wifi is active *and* connected to a network, the Data through HSPA is automatically disconnected.
I always thought it was a battery saving feature - if you have Wifi access, and presumably internet access, then you don't need internet through the cell network, right?
So if you're not getting internet access when your wifi is active and connected, then perhaps it's a problem with your wifi router not passing external internet to your phone?
The thing is nothing changed besides the firmware. wifi worked fine here in the house before and no problems connecting to the data network on the go with wifi enabled. I'm really running out of ideas here.
I guess I misunderstood you before. Are you saying you have no data access at all when wifi is enabled, whether or not you are connected to a wifi network? If that is true, something is definitely wrong. That doesn't happen to me with KG3 - just checked.
Have you tried reflashing the modem file? Maybe it got messed up in your flash before?
Sent from my GT-I9000M using XDA App
yes, no data regardless of wifi connected or not, as long as its enabled.
which is the modem file?
just an update, this seems to have mysteriously fixed itself.

[Q] How to force HTC pure using only 3G

Hello,
I have a HTC Pure from AT&T with stock ROM. It runs WM6.5 Professional. CE OS 5.2.21849. build 21849.5.0.63
I'm using it with a provider whose frequencies are such that the phone can only connect to 3G, at least I never see it connect to anything else. That's ok, but when there is no 3G network available or weak the phone tries to connect to the normal network (it shows a small G at the top of the screen, I don't know if this would be from another provider?) which it cannot connect to. So sometimes it takes forever to redetect the long reestablished 3G network.
Is there a way to force the phone to only try to connect to 3G? A registry hack maybe? I read in another post something about a "band" tab under "system", "phone". I can't find this tab.
Most often I'm able to immediately establish a 3G connection by turning the phone OFF and ON via the connection manager.
Any ideas?
Thanks in advance

use BandSwitch apps, so you can easily control the network connection
The link you posted doesn't work anymore. At least not for me.
But I found the software somewhere else. Seems to work. I'll check if it remains on the 3G network.
Thanks a lot.

Thanks a lot.

Tab on stable 3g but cannot use data

I have a Sprint galaxy tab I flashed to Visafone CDMA in Nigeria. I have been doing this for a while and everything works ok. Recently my tab stopped browsing, even though I have stable 3g data on it. I cannot use data on any apps on my tab, but strangely enough the hotspot works on other connected devices. I can use data on other devices connected via its hotspot. I can even use the usb dialup on the tab when I switch to modem mode, infact that is what I am using now to write this. I tried to activate daily data plan on my phone on the same network to see if it was a network issue. The phone is browsing well on the daily data plan, so it's not a network issue. Has anyone experienced this before? How can I solve this problem? Any help is appreciated. Thanks.
EDIT: I found the issue. Somehow the modem got corrupt, can't figure out how and when. I flashed VZW EF01 GBLeak with its EF01 modem and I'm back browsing on the tab again. I will try and get another copy of the Sprint EF17 modem and reflash the original Sprint GB ROM. If it fixes this problem then well and good, if not...
