manual network selection still switches to other networks

Hello all,
I've tried searching for this, but didn't find anything about it, so I hope that's not due to me having bad searching skills :?.
I have an MDA Vario from T-mobile (dutch), and am using it without letting the preloaded software run (by softresetting right after initial WM5 setup). It works perfectly fine, but I have one problem with it, being that even though I manually set the phone's network to T-mobile, when I go into Belgium it still switches to another network.
Since I have an unlimited GPRS plan, I just leave msn on all the time, but I don't want it to be causing any GPRS traffic while roaming on another network (which would be expensive), and since internet is the only thing I use the phone for (I have another phone I use for general voice calls), I would like it to just not register to any network at all when it can't find my home network.
Oddly enough, my motorola MPX200 (running windows mobile 2003) seems to be having the exact same problem (which is why I was surprised to not find any topics discussing this before). My colleague who has the same phones (MPX200 and Vario) also has the same issue.
Since I live really close to the border, I have to be very vigilant about this to avoid high roaming costs... If I can't fix this on the phone side, I guess I'll have to ask T-mobile if they can place a roaming bar for me.
Does anyone have any idea how to fix this? Or, in some odd MS logic, is it supposed to behave like that??

Have you tried going to "Phone > Menu > Options > Network >Set Networks" checking only your network, unchecking the rest, and setting "Network Selection" to "Manual" ?

Ahh, actually I hadn't. I tried to go to that screen earlier, but it wouldn't open. I guess I had my eyes in my backpocket since it clearly says to terminate the active connection and try again .
Thanks for the suggestion, I'll see if it helps next time I head into belgium far enough to lose T-mobile coverage .

Good luck !

Well took me til now before I could test it, went into belgium to go to the cinema (saw chronicles of narnia... don't bother unless you enjoy childish disney flicks...) but it still switched over to another network...
Guess I'll just get a roaming bar on it, until I get smart enough to code something up to disconnect GPRS on other networks (pah right ).
Unless anyone else got any ideas?

Hi!
Well, I have the same problem.
I selected "manual network" and erased all preferred networks but my own.
Still t switches to the network with stronger signal.
T-mobile-Germany hotline said that this is the normal (??crazy??) functionality of the phone. Stunned.

Hello!
I have exactly the same problem with my Qtek 9100, I live in France and work in Switzerland. 2 or 3 times a day I have to check if the selected network is still the good one if I don't want to pay the roaming cost.
I've contacted a french developper to see if he is interested in the development of a little software that could help us... I will keep you informed!!!!

MMS&Data Connection Problem..

Apologies if this has been posted before, I have tried to find topics similar, but have found no resolution thus far.
My X10's data was working perfectly, then about 2 weeks ago, market stopped working at "Starting Download" never completed, and I couldn't download Apps! This suddenly fixed itself one night randomly, and all my apps downloaded and installed, but instantly the market problem continued when I tried to use it again!
Now, the 3G/2G connection is totally non existent, there is NO icon at the top.. I have tried restarting the phone, turning it off and on, sim and battery out, even calling O2 to get correct APN settings (Server field is black, is this right?) and I got no "green light" beside "mms" at the APN type field..
The signal was fantastic before, and my family are still getting 3G connection on their phones, so I ahve no idea what the problem is.. I installed a few battery saving things which Iv since uninstalled.. but i have no clue what to do!
Any help would be much appreciated.. Thankyou!

suggest backing up your apps and then doing a factory data reset.. it's a pain in the proverbials but worked for me when this happened a couple of months ago.

How do I go about doing this mate? Any easy way?

Hi - Before you do this.. Can I just check something.. have you check in your network settings that it's not switched off... settings; wireless controls; mobile networks; MMS and data (needs to be on!).. and network mode - best to have it on GSM/ WCDMA Preferred to make sure... otherwise.... to answer your question above..
That will depend on whether you've already downloaded a file/ app manager such as ASTRO which will allow you to back up the apps.... if not you'll just have to make a note of which ones you want to reinstall and re load them after you've reset the phone.. the reset is done in the settings menu - sd card and phone storage - factory data reset... it will reset your phone back to how is was when you first got it though..

3G connectivity issue when leaving wifi zone

So, I've done quite some looking around in this forum and others but have not been able to to find an answer...
Here's the issue: when leaving an area with wifi connection, my galaxy s refuses to connect via 3G. Sometimes the "H"/"3G" is shown but no data is being transfered, sometimes the "H"/"3G" doesn't even show up. I've tried switching to plane mode and back, but that only helps sometimes. Switching to 2G and back doesn't help either, neither does re-selecting my provider from the provider list in the wireless settings or turning wifi on and off.
I'm on JF3 still. And here's the question: Is this an Eclair bug or firmware related? And is there a workaround, besides switching to plane mode and back every time I leave the house?
Your help is appreciated!

I have similar issue too. I hated it.
It appears to be an Android problem.
http://code.google.com/p/android/issues/detail?id=2207

I have this problem too, running an optus one.
I think sometimes.. going into the APn seetings, clicking on the field, dont change anything and press okay.. so it refreshes the APN settings and it works?
Or I rescan for networks. and choose my optus provider again.
Such a fluke.. that first few days i got this phone didnt have this problem.. and now it does... hope it gets fixed soon.

Okay, thanks. will try my luck with the android developers...

I checked out the link to google code and there seems to be a solution: restoring the default apn settings (hit the menu button when in the apn list). Seems to work, at least for now, my 3G connection came on when I left wifi after being on wifi for a few hours.

Australia S5 Internet 4G playing up since coming back from holiday

I have an Australian S5. I went to England for 2 weeks and used a UK SIM card. All was fine.
Since coming back to Australia and using the Australia SIM my 4G shows I have internet but to get the internet to work I need to turn mobile network off (4G disappears) then turn it back on again. Afterwards 4G works fine.
When I have the problem, 4G will show but there is no activity. If I try to check email for example the email app (default app) starts to refresh and then just stops like there is no new email.
When I was in England I had a notification that there was new software. I updated the software over the air. All seemed well.
The phone is completely stock and not rooted. I haven't tried anything to resolve really.. except these two things:
- Rebooting phone - problem comes back after a while say 24 hours
- setting the APN. If I choose another APN, for some reason the one I was originally on is re-selected somehow. I don't know how, may be the provider has some control over this? I use Telstra.
Any help appreciated.

I've created a new APN and removed / re-inserted the SIM card but problem still exists.
I've no idea how to troubleshoot. Has anyone got any suggestions?

I fixed this over the weekend. It was the "restrict background data" option in power saving settings.. I turned that off. All good now. :good:

No data after having WiFi enabled for a while

Hello,
I've had this issue across more than 1 device and more than 1 carrier.
Here's what happens:
I enable WiFi, and for a while everything works as expected. I can send and receive MMS messages. I can disable WiFi and go back to my 4G connection.
The problem is, after an unknown amount of time, the phone drops the 4G connection in the background. I only know when I can't receive/send MMS messages anymore. At that point, if I disable WiFI there's no 4G data connection, and I have to turn Airplane mode off and turn it back on.
This is really annoying. It happened to me using Sprint and a Galaxy S4 (both stock and custom ROMs) and it's happening to me with a Galaxy S5 from MetroPCS. (I've used the stock Metro ROMs, Stock T-mobile ROMs, and Custom T-mobile ROMs).
Right now I'm using a Stock T-mobile ROM with the latest firmware, carrier is MetroPCS.
What can I do so this doesn't happen? It's really frustrating.
Thank you for your time.

Disabled "Smart Network Switch" in WiFi Settings?

Disabled "Smart Network Switch" in WiFi Settings?

Hello.
That's already disabled.
Should I enable it?

I tried with "smart network switch" enabled and disabled and problem still happened.

My S5 G900F Android 5.00 (Smart Network Switch disabled, Power Save disabled) on EE UK has had this problem for 9 months after phone upgraded itself to Lollipop (EE win the accolade to being the SLOWEST ON THE PLANET to provide Android updates.....). Since Jan 3, my wife's G901, a couple of weeks after it upgraded from 5.0 to 5.02, has developed the same problem. Neither phone has ever been rooted or other.
I have fruitlessly searched everywhere for a solution without success. EE Customer Services Tier 2 & Samsung's own service centre have failed to fix it. EE & Samsung blame each other for 5.1 or 5.1.1 not being available for download. Neither is prepared to resolve the issue despite hours on the phone. Have tried Safe Mode, Factory Reset, clearing everything, reloading APNs & Samsung even reloaded Android. All a waste of time: Many many days of it!
After approx half an hour connected to Wi-Fi, only way to get the mobile data to connect, is either reboot, enter & exit Air-plane mode or flip the 4G > 3G > 4G connection under More Networks. Have tested the fault in different cell areas countries and continents; fault is same everywhere.
It seems there are quite a few sufferers of this problem.

Samsung S5 keeps losing data connection
I have the same problem. My new Samsung phone loses the data connection (even though data is turned on) and I can only re-connect by restarting the phone. The first EE shop I took it to couldn't help at all. The second gave me a new SIM - that didn't work. Then I tried online support and after 3.5 hours of my life, in which I was passed on from one person to another, they completed a factory re-set - which didn't work (and additionally lost all the personalisation of my screen and some of my contacts). So I now have a not-very-smart phone which I have to re-start every time I want to use data. This is a business contract and the phone is less than two months old, but I'm not getting any effective support from EE. Android version is 5.0.2

me too, since last update. and app 'phono' shows "mobile data off" not got a time on it, but when i leave wifi coverage, it wont reconnect to cell data 2g/3g/4g. flightmode toggle to restore.

Abandon hope if you have this intermittent mobile data problem!
...at least until there is a software update, though I have no idea if that will help.
I have now tried a new sim card, a factory reset, and a replacement phone - which was provided only because I'm a business customer and I found a sympathetic member of staff. *By the way, I was told that if you are personal customer they won't consider replacing your phone if it is more than a month old - even if you started complaining about the phone as soon as you got it, the chances are a month will have elapsed by the time they put you through the hoops of a new sim, reset etc - and then it is too late to insist on a replacement phone.
In any case the replacement phone didn't resolve the issue so I have reached* a dead end. My phone fails to connect to data after having been connected to wifi - you have to do it manually each time you move away from a wifi connnection. At first I was doing it by restarting the phone, but am now following the advice of someone else who has the same problem and am going into flight mode and out again. *
This is not satisfactory, and it seems from reading forums that EE are to blame for the problem rather than Samsung, but I'm not 100% sure about that.*

Possible solution that works, for me, at the moment!
Having suffered this issue of my S5 (SM-G901F) not connecting to mobile data after being on Wi-Fi for a while unless switching airplane mode on/off for a few weeks; although it has probably been happening since the update I received late December; I have tried all of the turn this switch off, factory resets (x2), etc, etc, etc. and Googled the issue without success.
I have found this thread interesting, and I even tried calling EE support only to be told "you have tried everything that we would tell you to do" and "it wouldn't be a sim card, or handset issue, sounds like software". The reply was basically that like-it or lump it until the 5.1 update is released "by Samsung not EE because EE do not release Android updates". [Perhaps EE don't release the updates, but the stock rom is tested by them and their bloatware added before they eventually release it!!!]
Following my last reset I tried selectively re-installing the apps I used incase that was causing the issue. No Luck!
One last thing I tried was to look at every system 'thing' that I could find which used/switched any part of the mobile/mobile data/wifi - in addition to the settings I had already tried (all of which were mentioned in this thread previously). One thing I could not find not mentioned here, or anywhere, was the VoWi-Fi call on/off which I had always set to on as I do not live in a great reception area. Calling over Wi-Fi is great when you don't have a strong mobile signal.
Having 'played' with this setting for the last 24 hours I have found that the VoWi-Fi on/off appears to be a possible cure - for me anyway.:fingers-crossed:
When VoWi-Fi was set to off and leaving the phone connected to Wi-Fi overnight, the S5 immediately switched to mobile data this morning when I turned the Wi-Fi off . It continued to switch between Wi-Fi and mobile data all morning whilst out and about in and out of Wi-Fi connections - Woop Woop!!!
I then tried switching VoWi-Fi on (with Wi-Fi on and at home), leaving the phone for a number of hours, only to find that when I turned Wi-Fi off the phone refused to connect to mobile data even with a 'decent' mobile signal. The only way to get it to connect was to go back to switching Airplane mode on/off.
Switched VoWi-Fi off again, left Wi-Fi connected, left the phone for a couple of hours, etc. and hey-presto immediately switched to mobile data when I turned the Wi-Fi off. [Dances around the room because he's got the S5 automatically switching to mobile data again. Even though I'm at home with a great fibre internet and strong Wi-Fi connection!!!]
I do not know if this could be a solution for the others who are suffering from this issue, but it appears to be a solution for me at the moment. I thought I would share as your previous posts have helped me and you all seem to be pulling your hair out; like I have been; trying to find a solution.
Try it, it may work, but don't shoot me if it doesn't!

It's encouraging to know that I'm not crazy. I've had this issue across two devices and carries.
John,
Thank for your suggestion about WiFi calling. Unfortunately, I always have it off! I never used it, so maybe I should try turning it on? We'll see lol.
At this point, I think this is going to be my last Galaxy line phone.

Is it wi-fi calling that's causing the problem?
I have wondered if there is a link with wi-fi calling, but haven't tested it properly. I signed up with ee and bought the Galaxy phone specifically so that I could use wifi calling, as the town where I live (in the Scottish Borders) doesn't get a mobile signal strong to work reliably indoors from any of the networks. I'll try turning off wi-fi calling to see if that sorts the data thing (though I see that for one person above it did not). That would mean I wouldn't get calls or texts when I'm at home so it would not be a permanent solution for me. But in fact the wi-fi calling is not reliable anyway....

Brian,
You never know the way things are going with this issue; given that nobody seems to be able to pinpoint the fault; turning it on may just sort it!!!

still no change and its a pita.....
