Data connection keeps randomly not working?

It seems random when the data connection works and the internet works on my phone. I'll sit there with full 3G signal and i get "cannot find the DNS Server" error when trying to load webpages :S
is this a problem with my Samsung Omnia 7, Windows Phone 7 or my network (Orange UK)?

I have this problem on my HD7 as well. If I have a 3G connection, it doesn't work. It only works on H (HSDPA).
Funnily enough, I had the same issue with my HD2 running WM6.5, which makes me wonder if WP7 is using the same comms drivers.

I have this problem too! A LOT everyday in diferent locations.
Actually how can I enable the HSDPA on my HD7? Because I can only get 3G.

These are just network errors.
I use internet alot and it happens on every device I had.
My WP7 is actually pretty stable in this regard.

Same! Never works on 3g only ever H you sure its just network errors cause it happens alot

YES this is a major problem for me with my Omnia 7, I even got a replacement phone from my carrier (Optus Australia) because of it... and it's exactly the same. It's extremely frustrating and makes the phone damn near unusable. Happens on every device? what a load of rubbish, if I put the SIM in my old iPhone 3GS it works FLAWLESSLY. I don't know what I'm going to do.

Can you explain then, how come a reboot always fixes the problem?

Yep, I have the same problem with my Omnia 7.
On all 3 of the networks i've used it on, T-Mobile, Virgin and GiffGaff.
Only solution is to reboot the phone.
I thing i've noticed, is it seems to happen when I move from an area where I have WiFi access (Home/Work/Cafe) to an area where i'm using a Phone network ?

I think we can only hope that the upcoming WP7 update fixes this. Also it seems enabling airplane mode then disabling it also fixes it in a similar way to rebooting the phone.

I'll make a note of that, cheers!

Im having the same issue with my HD7. Only EVER works on H. Not on G or 3G. It's driving me insane. The exact same sim on the same provider never had an issue on my Touch Pro 2, but this phone is shocking for internet

I get this occasionally on my HD7. Not really an issue right now. It does get annoying sometimes when the wifi in my house isnt strong enough to connect

You do realize that phones switch to H only while they are actively swapping data, then fall back to 3G while dormant, to save battery?
Try it - leave your phone alone for a bit and it will switch from H to 3G. Now access something on the net and it will switch to H (if possible) to get the data, then after a few seconds of inaction it will switch back to 3G.
So yes, it is correct that it only ever works on H!
Mind you, it would be nice if it worked on G too, I'm sure it should but mine never does.

hm i thought the " H " means that i dont get 3G signal.
but i think i had the same problem!
solution:
you only need to turn OFF WIFI
somehow its not using 3G when wifi networks are close,
even if you not connected to one.
turn OFF wifi or maybe only "discover new networks"
turning OFF wifi always brings me 3G back ...

Just to add my experience here...
I have a Samsung Omnia 7 and had never experienced any issues with 3G/H data/internet issues on the 3 network in the UK.
However, I've come over to Australia to visit the folks and have put in a Virgin SIM, now I really struggle with this. The connection just isn't working even with full 3G signal.
As pointed out, toggling my Airplane Mode works most of the time - I guess this is because the phone re-registers itself with the network when you enable>disable airplane mode (just like it would if you rebooted it). Curiously toggling the data connection option seems to have no effect.
Pain in the a*se.

I had connectivity issues with my Samsung Omnia 7. I worked out that my phone was not playing nice with my router and so my wifi connected but didn't actually work.
Also, I found that 3G performance was sub-par and many apps timed out because they were taking so long to get connection.
I solved these problems by flashing a new firmware. It was a little tricky and it is potentially risky, but a quick google will lead you to the relevant information.
I used a European firmware (I am in Australia on Optus), but it works fine. I just had to change all the language settings.
Now my phone's 3G and WiFi connections both work a lot faster (no more waiting for an eternity for the marketplace to open for example).

I have the same problem and read on create.msdn.com it has something to do with how wp7 handles the connections.
If the provider cuts off the connection frequently it loses its 3g signal or something like that. Thats why my push notifications are just unreliable. If I take my sim out and use wifi only. It just works and keeps working as soon as I connect to wifi. When 3g comes into play and the carrier cuts me off because im not actively using, the phone struggles to recconect for push etc.

MetroPCS blocking data on flashed phones

I can confirm that MetroPCS is blocking flashed phones from using their 3G data network as of today, November 5, 2012. I had my Epic 4G slider flashed to Metro around 9 months ago. 3G worked up until today. I let my service lapse (for all of 12 hours) and after I paid to have it reconnected, my 3G no longer worked properly. It is actually still connected to the Metro 3G network and 3G shows in the top bar, but the only webpage accessible is a page titled "metropcs_tethering_message" which states:
"Per the Terms and Conditions of Service, Tethering / Mobile Hotspot is not currently supported. Please visit --- for terms and conditions of use."
To be clear, I am not tethering or using the phone as a hotspot... just trying to surf with the phone itself. The days of flashing to MetroPCS and using data seem to be over. I wonder if it has anything to do with their impending merge with T-Mobile?
Time for me to find another inexpensive call/text/data solution.
[email protected] MetroPCS!

Its been like that ever since they blocked tethering.. some cities were opted out from 3g before tethering was blocked. Requesting the desktop version of a site on a metro phone makes that same message appear. It's likely to be an easy workaround but worth the trouble? Certainly not. I suggest you take a look at the virgin mobile guide in my sig.

Well, an interesting development...
After buying a new (to me) GSM sim-based phone (LG Optimus G2X) and signing up with SimpleMobile, I was prepping my Epic 4G slider for sale and re-flashed my rom to the same custom rom I had been using for many months (ThunderHawk EG22 with Nubernel 2.6.35.7 kernel). After I did this, my data connection started working again. Might not stick, but it's been on for a couple hours now.
Now, this wasn't some glitch or bug in my system that caused the data connection to stop working as stated in my original post. I confirmed with MetroPCS that they were actively blocking my data connection, so it wasn't something wrong with my phone. However, after reflashing the rom, it works again! I'm still selling the phone though and moving on from GhettoPCS.
I'm posting this so anyone else who's had their data connection blocked can try reflashing their rom (even the same rom, apparently) to try to get their data connection back.
But once again, [email protected] MetroPCS for blocking flashed phones! Why do they care where we get our hardware to use on their shhitty service?

That may be the placebo effect, many outdated Epic Roms improperly displayed 3g icon when it was in fact 1x.. you should do a speedtest and verify its Evdo Rev A or Evdo RevB and not 1x..

HELP

In Atlanta for the Final Four. Phone was working fine until last nigh, running $myname's 3/11 AOKP build. Mobile Network says that I'm connected, both 3g and 4g. Can't access Play Store or anything that uses data.
Can anyone come to my rescue? I'm limited on hotel wifi and am currently downloading anything ROM to see if that fixes my issue. People can call me and text me but I can't respond.
HELP!

[Q] bad mobile data

I'm having this connection issues where the phone would show the 3g/4g icon but the connection is really slow( slowest speedtest gave me was 0.01mbps). Im testing with a different provider now but is it possible this is a hardware fault?

Same Problem
I have a similar problem, when I enable Mobile Data, it could not connect, I have to turn Airplane mode ON and then OFF and then Mobile date On to get the Mobile Data... Very Irritating... I hope its SW issue

I have slower connection on 3g and h then previous devices

Well its only 4g giving troubles now, is 4g and 3g on one chip or a seperate chip?

Try cleaning cache of your browser

Don't think its browser related because its systemwide. Plus i tries a factory reset already

I've gotten this as well from time to time. Doesn't seem related to whether or not I'm transitioning from Wi-Fi to 4g or not.

I'm getting the same and came on here specifically to see whether it was just me.
These are the symptoms: it seems to happen when I transition from a WiFi network to mobile data network. The data icon still shows activity and good signal but internet access is incredibly slow or non-existent in all apps. Toggling in and out of Aeroplane mode fixes it. I am on a 3G SIM, so for now I have tried to turn of 4G mode and see if this fixes it. Will report back.
This is really annoying - my £100 Acer Liquid Metal did this like 3 years ago... I don't expect a modern £500 phone to have this issue.
I love the phone but issues like this aren't acceptable and I'm getting really frustrated to the extent I might even send it back for refund under not fit for purpose.

Also I have problems with unstable network. Has anyone tried to restore the firmware?

I've turned off 4G as I don't have a 4G SIM, so I'm gonna see if this helps resolve the issue. If not, then I'm going to try and flash a different firmware as my handset came with a EUR firmware and there seems to be some differences between this and the UK firmwares. If that doesn't fix it, I'm going to try the AUS firmware which is a later version.
If I get an success or otherwise I'll post back.

I'm noticing that HTTPS traffic always seems to work fine, but standard non-encrypted traffic doesn't. Anyone else? Seems a bit weird.

Mobile data issue after pie update

Hey,
after updating to android pie I have problems with mobile data. In my area I usually have 4G or 3G but I now only have 2G a lot of times. I even compared the coverage with a friend who has the same provider as me but an iPhone, and she had 4G while I only had 2G. It also seems like I can't receive or send any WhatsApp messages unless I am connected to the WiFi.
Does anyone else have these kinds of problems, especially those living in Europe (I live in Germany)? Is there maybe a problem with LTE band 20? (my phone is not rooted, so I am unable to check)
I have the global version btw, and everything worked fine under oreo

You can try to reset the APN settings on your phone, that did the job for me!
