Samsung Galaxy S II :: Data Network Mode Not Working?
Oct 3, 2011
Am I right in thinking that the Data Network Mode access your data plan usage? Ie 500mb?When I activate this, it doesn't seem to allow me to connect to the net?Also is there a widget that allows me toggle this off and on?Doesn't it seem weird that Samsung hasn't give us a indicator like the wifi that this data network mode is ON? I could leave it on running without even knowing? Is there a good app which lets me see how much data I am using?

I installed the lite'ning rom around 4 days ago but since yesterday I'm unable to activate data network mode? It's ticked under the settings and i've tried turning it on and off but it still doesn't come on. When I hold the power button it will say its activated but if I wait 30 seconds it switches to saying its deactivated? Is this a problem with the rom?

The network mode on my Samsung galaxy S5 device is always set at GSM only. When I try to change it to WCDMA only or GSM/WCDMA (auto mode) it changes back to GSM only. The area I am has 3G network and most devices I see have H but mine always shows as E no matter what I do. When browsing it takes a long time for pages to open because its always at E.
I have factory reset the device but still facing the same problem.

I get a poor signal indoors at home - on Orange and it's always been the case. I spoke to their customer services and was told to switch the phone from auto select for Network Mode to GSM only. My choices are GSM only, WCDMA only or Auto.
True, having done so, the signal strength seems better though not amazing but, ordinarily, I get then just a "G" for data. I found that switching to WCDMA only, data goes to 3G or even H and sometime H+ but I nearly always lose the standard signal.
I dont understand the difference between GSM and WCDMA nor whether the results I see when choosing each are to be expected or not. I'd welcome any information from those of you who know more about these things than I do.

when I plug my S2 into my laptop (Macbook pro) and choose data transI was expecting to see an icon representing the phone show up on the Finder desktop. That's not happening. Instead I'm prompted to "press the home key to quit Samsung Kies" Am I doing something wrong or do I HAVE to open Kies in order to see my phone's memory (32GB SD). My Nokia N8 would just show up on the desktop...not so with the GS2.
PS. Does using the USB invoke Samsung Kies to open up? I'm not seeing anything on my homescreen except the word "Connecting"...and the little dots that indicate the phone is thinking about something,..but nothing ever happens beyond that.

i have bought this unlocked phone for about 550$, but internet is stuck on edge(not even 2g) which is incredibly slow.Please help me solve this i have searched internet but just a few ppl has the same problem with unlocked samsung galaxy S2 and tmobile.That made me think that there might be a solution like changing the Tmobile sim card(i dont know if there is only one type of sim card), entering an unlock code provided by tmobile, or going to a samsung maintenance service and let them fix it or anyother? I have updated to the new firmware but did no effect.I cant understand how such a big company like samsungs' cutting edge new phone comes out of the factory with unsupporting the USAs one(Tmobile) of the 2(Tmobile,ATT) GSM networks data frequency.

So basically I went away for 4 weeks, came back, switched on my phone and now BOOM it won't call anyone, it won't use 3G or anything or even make texts.
Here's some useful information:
- I'm picking up signal, and can receive texts etc.
- when I try and call someone, it says 'you cannot make outgoing calls while call barring is on' (even though I've checked in settings and it isn't).
- I'm on o2 in the UK
- I've checked my status, and it says 'Mobile Network State' is 'Disconnected'.
- It's running 2.3.3
- I've got the Network Mode on Auto (as it always was when the phone actually worked), and also I haven't been playing around with the APNs or anything like that.
- I bought the phone legit from Carphone warehouse a few months ago, and it worked mostly fine up until I switched it back on yesterday. I'd had a few problems with non-wifi internet before I left last month, but nothing affecting making calls etc.

Yesterday i used the the mobile data connection just as normal. I downloaded from the store and everything. Then i was back in wlan. I tried Fring. I wanted to try Fring also on 3G or Edge or HDSPA or whatever comes out from my handy and goes into the air ^^ I don't know anymore.So I turned off my wlan and was down. No internet anymore and even there was no icon in the toolbar.
I turned my phone on and off, unistalled every app i installed since the last time it worked, which was just an hour before that.
The things i installed were: A brightness widget (appears under volume controll if you press the volume buttons. I forgot the name.) and "Quicksettings", which leeded to uninstalling the first mentioned unit.After that didn't help either, i changed the card in my phone with another from the same provider. It didn't work. In the same move i put my card to another smartphone and got a connection.Conclusion: Either my phone is misconfigured (which i hope for) or it's broken (which would suck but i have warrenty left).
I even tried to let my provider send me the right connection data and saved them. Nothing...I know there is the way of getting back to factory settings, but i only want to try that if i'm running out of possibilities. And of course i don't want to lose my app data. my phone is not rooted now and i know i have to, to save my app data and apps (which sucks. 1-0 for the iPhone). I you have only ideas that could be done by rooting my phone i would do so, but i would rather avoid that because of the 'maybe warranty loose'.

it's weird cause when I toggle off the Data it shows a line across the "4GLTE" but right now its just grayed out not letting me use data at all.

I'm having some really annoying issue with my phone, when I select the Network Mode to GSM/WCDMA (auto connect) it is working perfectly fine but as soon as I change to LTE/GSM/WCDMA (auto connect) I lost 75% of my signal.
Of course without activating LTE I cannot access the 4G Network which is a bit annoying.
I also tried to flash the latest modem for my phone g920i but it didn't solve the problem.

I have a S6 edge and trying to find out where is the network mode can be found. Far is I know, it should be under the "mobile network" menu, but is not there. All I have under the "mobile networks" menu is: Mobil data, International Data Roaming, Access Point Names and Network operators. None of these including the "network mode".
If I try to find it in the search, it takes me straight to where is should be, but again, is not there.

I have a Samsung flight. I unlocked. I want to use it on the Tmobile network. But I can't seem to get the internet working on it. It there maybe a flash I could do to remove the Att trademarks from it and also getting working on my Tmobile network.

This is a strange one, last night I picked up my phone and had no data signal at all but a fairly strong phone signal, I assumed it was ee, they've been appalling lately, I turned my phone off and on, toggled flight mode on and off and it made no difference, I went into the network menu and I noticed that the mobile data was turned off, I turned it back on and all was well again. Just now I picked my phone up again and my mobile data was switched off and my phone was disconnected from the network altogether, how is this possible?

My wife just came back from overseas and now her phone will not detect our wireless network, just says it's "out of range", yet my phone connects fine. I have checked all the settings which are ok, reset the phone and the router to no avail.

IMEI can be seen,everything is fine, when plugged in my orange sim card it just said "mobile network not available". The signal strength is fine and can be seen. I tried an O2 sim card, a talktalk (vodafone) sim card and they both worked fine. both of my 2 orange sim cards didn't work on this phone, but they worked fine on my other 2 phones. latest update, just flashed orange stock rom KJ4, got the same problem.tried manually connect to orange, got notice that "unable to connect, try later".
some more detail:every time when I flashed a new rom, always a notice saying "can't access to "/system/csc/ORA/system/". Tried *#272*imei#, there was no optional CSC available.

I have tried reinstalling the frimware and all that did was lose my apps. Tried doing a different firmware and tried rooting all the same results. The phone is definitely unlocked and unblocked as while I was searching google I came across one of those secret codes to show the status of the locks and all 4 of the categories were unlocked. I have tried a batterry pull and tried cleaning the Sim card. Also just in case this helps when I g into Settings>Call>Additional Settings it says 'Network Or Sim card error'. However the Sim card is perfectly fine.

I recently got my S5 and my data connectivity has stopped working after I took a flight. I had enabled flight mode on and turned it off when I landed. I'm still in the same country. Before this, I used to only be able to connect to H+ but I'm positive that my data was set to enable 4G LTE. My SIM card works on my old S3 and 4G LTE is being used. I'm not sure what's going on, I've tried resetting my phone a bunch of times and playing with the settings.

I just rooted and unlocked a SG2 that was on the 3 network. I ran Galaxy S2 SIM Unlock after rooting using ODIN etc - I put in the unlock code and it said unlock successful. After putting in my Orange SIM and switching on, I am getting the network error symbol and am unable to make calls. (Interestingly, I do get the Orange SIM Plus app icon on the phones desktop. Also, the phone still boots with the 3 logo - was expecting this to have disappeared completely!).

suddenly my Samsung Galaxy S2 can't access the wireless network. It has worked before but now it seems to be hanging when searching for wi-fi units in the network. I can access Kies via usb-cable.

I have signal and I can make calls/send texts but the o2 icon on my main home page has disappeared, it's really irritating me lol!
My mate was mucking about with my phone earlier and changed the wallpaper to a pic from facebook so I'm thinking it maybe has something to do with that... I've been through the settings and can't find anything... been in the widgets to try and get it back cause I remember on my old samsung you could put it on the screen as a widget... but no luck!
I've turned it on and off but no luck, and I don't want to have to resort to restoring it to the factory settings cause I don't want to lose everything..

I mainly use my Galaxy S II to access my WLAN and rarely use the phone for telephone calls. Yet my pre-paid credit is constantly being eaten up?
I think the phone is set up to automatically select the best network. Normally this will be my WLAN,but I suppose,if I am in an area of the house with poor WLAN coverage,the mobile network is automatically selected?
How can I block this automatic (non-option)?

when I set my phones alarm clock at night, the phone has recently started going into airplane mode of its own accord. This isn't affecting the alarm but obviously I am missing any texts or phonecalls coming through and don't get them until I wake and change the phone mode back. I am running ICS 4.0.3 LPS rooted using Chainfires kernel.
