Samsung Galaxy S II :: Mobile Data Connection Isn't Working

Jul 21, 2011

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'.

Galaxy S6 :: Why Losing Mobile Data Connection When Screen Turned Off

Aug 27, 2015

I have a Galaxy S6 (64G) from AT&T. I've been having problems receiving Whatsapp notifications when the screen is turned off for a while. I measured that it takes about 10-15 minutes after the screen is turned Off using the web interface for whatsapp. I have enabled notifications to always allow pop ups in the appI checked that restrict background data is not enabled for WhatsppI have set Whatsapp notifications as priority under App notificationsChecked to make sure that So not disturb is set to OFF.

After the connection is dropped I see all the missed messages and notifications showing up only after opening the app. This has been very annoying and I've been unable to respond to important messages in a timely manner if the phone has been idle for a while.

Galaxy S6 :: Mobile Data Not Working

Oct 11, 2015

this is my 3rd post about my mobile network problem. I am not getting 3G service in my mobile. What is the possible reason behind this? I can only use 2g with slow data speed. When I choose wcdma/GSM, then one message appear "emergency calls only". Frequency is full but why this happen? In my area 3G is fully available.

Samsung Galaxy S II :: Unlocked It Got Stuck On T-mobile EDGE Data Network?

Jan 11, 2012

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.

Samsung Galaxy S II :: Turning Data Connection Automatically On For MMS Retrieval?

Sep 20, 2011

My previous phone was HTC Wildfire S (stock Android 2.3.3) and I was able to receive and send MMS with data connection turned off. Simply, when I send MMS phone automatically turn on data connection. Same, when somebody send MMS to me, Wildfire S automatically turn on data connection and retrieve MMS. Now I am using Samsung Galaxy S2. I have to keep data connection always on if I want to send and receive MMS. I don't want data connection to be always on because I haven't flat data plan. I tried Quick Setting app. It change APN for internet and keeps data connection always on (do not modify MMS settings). At this way I can use MMS normally, but my battery drain for just 8 hours!

Galaxy S6 Edge :: Why Getting Mobile Data Background Usage With Mobile Data Disabled / Background Data Restricted

May 23, 2015

I have a new T-Mobile S6 Edge and love the phone, but one thing I have not figured out is why I still get background mobile data usage even though I have disabled mobile data and set "restrict background data". Both tuiService and OS services are downloading approximately 100K at a time periodically over mobile data throughout the day even though I have a wifi connection.

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?

Xperia Z5 :: Cannot Get Mobile Data Connection To Work

Nov 2, 2015

I cannot get the mobile data connection to work. I have restarted the phone, contacted my network provider for the information to set up a new connection, have updated the software, have done a reset but nothing is working. I also do not have the 3G symbol next to my network provider so something seems to be missing or not working correctly.
I have put the sim into my Iphone and I do not have any problems. It immediately connects to 3G and I have internet and do not have to change any setup info. Its pretty frustrating as I have only had it for less than a week but have spent most of the time searching for a solution and am wondering, if there are this many issues, whether not to just return the phone. Any tips to setup the mobile data connection?

Xperia Z3 :: Mobile Data Not Working Suddenly

Sep 20, 2015

I have a three month old Z3 on Vodafone in the UK. I have travelled abroad with it 4 times in that time. The first 3 times were fine. Data worked as normal. This month I went to CZ Republic where it was fine. Flew home Saturday. Flew to Spain on the Sunday - no data roaming. I could get texts and make calls but could not get internet or even pick up a 3g or 4g signal at all - even though my 3 friends, all on vodafone right next to me had no problem. I called vodafone and took it into a shop over there. They reset all of the settings for me including setting a new APN etc.Still nothing. They are insistent it is a software fault with the phone - not a connection issue.I landed back in the UK last night and I am picking up data fine again - but I go away next week again and need to make sure it will be working.

Xperia Pro/Neo/V/L :: Mobile Data Stops Working - Needs Reboot?

Nov 24, 2011

Every so often, mobile data stops working (and no symbol for data on the phone)Signal strength is strong.Switching mobile data off and on again, re-selecting network, switching GPRS/3G does not fix it.The only way to fix it is to reboot the phone. I think it usually happens after I've been in an area with low/no signal for a while. (Obviously when I have the signal back, I expect the mobile data to also come back automatically).Neo 2.3.4 Operator Simyo (Spain)It also happens to my wife's phone (Neo 2.3.4 Simyo as well) Is this a known bug?
