[PROBLEM] GSM network switching - how to disable - Android Q&A, Help & Troubleshooting

HI, I am a lucky (for now) owner of OPX.
I have problem with network switching. Iam living in small village and i have to use network roaming (yes, i can use others providers network as well for free - in my country).
I'am in P4 network(base/mother network), but in my village there is no good signal for this network - so, i just using another one - usually PTC 3G because this network has best signal in my area.
I have few android phones in the same network (P4) and when i select network, phones do not switch to any other network - even if there is no signal of this network (Nexus4, Nexus5, Sony Xperia Z and CAT S40).
With OPX its different, and very problematic. When i switch to PTC network, it works and not switch to any other network until i left the phone and let it for sleep... (5-10 min) then network switch to the base network P4 and ussually there is no signal in this network, and i have to wait until i can make a call or send SMS message. I dont have the problem with any other phone. I see, that the problem intensifies in specifed room, where is Wifi(dualband) router - but not only. I suppose, its software problem.
EDIT: Switching to P4 network happens when phone screen is off and phone is in idle, after turn on the screen and waiting few seconds, phone ussualy connecting to PTC netwok with good signal.
Screen with bad signal: 1drv.ms/1JmvSU1
EDIT2: I found another freaky thing, after while of phone IDLE, iam turning on screen, and there is full P4 signal, after 1-3sec freeze (yes, freeze, laag) signal agin is 0 and i can enter phone PIN code to unlock.
And there is my question, how to make this works well ? Is there any way to force select only one network ? (i dont need switchning). Maybe can i do this with root privilieges ? I hope, you can help me guys.

issues reconnecting to mobilicity network -canada, please help!

Hello there I currently have an unlocked vibrant currently on the mobilicity network in Toronto, Canada.
The phone works well, no issues except for establishing and securing a connection with the network provider. Every time I go to an area where it loses service, like parking garages or subways it loses the connection- obviously- but when you get back to an area where there should be service I only connect to the roaming service. This is leading to extra costs since my plan has charges for that.
What I do now is when i go somewhere with no service i switch to flight mode. When i get back where there is service i have to usually turn the phone off and restart it and search for a network manually.
Are there any apps, hacks, or fixes that can stop me from seeing or detecting roaming services, and force the phone to lock on to my network provider's service?
I want to use it only in the current home zones, and if out of one, i accept the fact that the phone does not work at all. I am always in the coverage zone and never want to use it while roaming.
can anyone help?
At the setting, there is an option there Data Roaming, you need to check or uncheck it. Select the option that will prevent you from doing data roaming and that should fix your problem.
On the otherhand, I have a question for you. I have the same phone and same provider, mobilicity. Our problem is the 3g connection. It is spotty sometimes the 3g icon appears and then disappears. Does this happen to you? I noticed the problem occurs when I go under like basement when there is no signal. After resurfacing, I gell signal reception sometimes full but the 3g or data connection won't work. To solve this, we would usually shut down the phone and restart it. Do you experience the same problem? If yes, what was your fix. Thanks.
David
Same problem here. Any guidance will be appreciated.
I've done the suggestions for Wind but to no avail.
same mobile , same provider , same issue
hai guys i have the same issue , but my thing is more worser than you.....when ever i go to an underground parking my 3g gets turned off and wen i come out from that place i cant able to make or receive any calls .....i need to restart the phone to turn on the signal again...its really weird any one have the solution ?????
Hey all, I have a Vibrant on Wind, this is what I do.
Go to settings.
Wireless and Network -> Mobile Network -> Network Mode ->WCDMA only
This enables that you stick to Mobilicity's 3G network and not roam on the Rogers 2G network.
If you lose signal, you will not roam, but simply not be connected until you move out and pick up Mobilicity's signal again.
Hope that helps.

I found this on Howard forumns:.... I know this post is old but the solution could help someone who recently bought a old for to get used to customization /flashing.>>> Hope its useful
From Post:

It works!!! It totally works!!!! I love it! Thank you so much guys!!!! Now I don't have to restart my phone EVERY morning as soon as I pull out of the underground garage in my car!!!
Thank you, Thank you, THANK YOU!!!!!!
Dial: *#*#197328640#*#*
Click [1] debug screen
Click [8] phone control
Click [7] network control
Click [2] band selection
This is where you make a change, default setting is [1] automatic, which means it chooses automatically between gsm/cdma (Edge vs 3g). So we are going to change this and set it to wcdma band which is 3g.
Click [2] wcdma band
Click [1] wcdma all []
Now it should display “select wcdma all bands[*]"
Now on the bottom of your phone, click the menu key, it’s the one next to the home key, now click back, menu again one more time, back one more time, this is just to confirm it set to number 2 wcdma band.
Now click menu key one last time, click end.. and you are done. Now to double verify that the phone is locked into 3g, dial in: *#*#4636#*#*
Then click phone information Then scroll down to “set preferred network type” It should now have listed “wcdma only.” PS, if you tried to do a shortcut, and just set wcdma this way first without doing the lock above, it would just go back to gsm/cdma auto once you exit the screen.
Your phone should now be locked into 3g.

Again found on Howard forumns and copied and pasted to word doc. to keep for my mum as she gets the phone.... I got her the the 27.50 holiday plan so she can call anywhere to anyone in North america with unlimited data....coverage is good so far...
P.S. i dont allow roaming as to not incure more charges.
I know this is an oldish thread but.
Trying to fix connection issues and the Dial code does not work for me. It just does nothing when I enter that. The only code that works is *#*#4636#*#* and that does not help me.
Anyone else having this issue and know why it's not working. I have an Amaze 4G. Only posting here about this phone because this is the only thread I could find related to my issue.
Searched all over now. Those codes are to be the only solution and they don't do anything on my phone.
Anyone have answers?
I have a mytouch 4g (it's actually the htc panache) that just suddenly wouldn't connect to the network after I restarted it. When I try to add a network manually, the only option I have is to connect to Canadian roaming...

1. Disable Mobile data, then wait for 3-5 minutes
2. Enter Service mode, then change network to WCDMA only, repeat it like 2 times.
Done.
Correctly good luck...

my problem is described here -Can others be so kind as to verify if they are also having an issue with receiving voice calls or SMS while their phones are using the 2G network for data access. (3G and wifi either unavailable or turned off.)
We have this issue with Orange and I have tested it on one Sunrise iphone4 and we had the same issue. Which is not surprising since Orange and Sunrise are operated by the same staff. It does work correctly over Swisscom.
I raised this case with Orange over one month ago and they still have given me no concrete feedback as to why their network behaves like this.
(FYI this is a network issue and not related to any phone configuration).
Feel free to harass Orange about this. It might get them to pull their fingers out a bit. When I raised the case it took me about 10 calls to their support plus 2 visits to Orange shops to finally get a technician who was capable of understanding this simple but critical issue.
EXACT STEPS LEADING TO PROBLEM:
1. Force phone to use GSM (2G) mode only or be in an area with no 3G coverage, or if your phone chooses to use the 2G network
2. Disable switching to wifi:
3. Connect to 2G packet data, download email or download webpages: Status Bar-> spinning wheel
4. While packet data is connecting, using another phone place a call to your phone
5. After packet data has connected, using another phone place a call to your Phone
EXPECTED OUTCOME:
You expect the packet data connection to either DROP or be SUSPENDED (depending
on network capabilities) and for the phone to ring indicating an incoming call or SMS.
ACTUAL OUTCOME:
The packet data connection persists and remains active; the phone does not ring
and the call is handled by the network as if the phone was unreachable (for most
users this means forwarding to voicemail).
REPRODUCIBILITY:
always; no exceptions.
This has been tested extensively on the Orange network by me and many other users.
Tested devices which all show the same issue, iPhone4, iPhone3GS, Iphone 3G, several Android models.

signal loss

I'd like to share the following info with all those who have identical problem with me.
Symptoms:
Phone randomly looses network carries signal, shows few or full bar reception signal strength but can`t receive or place a call until restart or manual/automatic network selection is initiated.
Solution:
Change / Adjust the network connection speed according to signal coverage, settings -> mobile network -> highest network connection speed. Usually lower the speed.
In my case it defaulted to 3G and i tried setting it to 2G, which solved the symptoms described before.
try change SIM card... if that not help maybe problem is in SIM card holder

probably i was not clear enough. I had (past tense) that problem, now i don't. btw i did tryed changing sim cards, hard reset, even sim card from one other network operator (who also had weak 3G signal), i was googling and googling and googling .... and somewhere i did find that sugestion for simmilar problem.
I had a similar problem, but found that the SIM was just a tiny bit loose. Once I popped it out, reseated it and re-inserted it, I didn't have that problem agaon.

[Q] losing 3g connection and network

Hi All,
I got the CyanogenMod 11 snapshot m12 in my HTC one x+. My 3g/lte connection automatically switches to edge and the network connection goes off but the signal strength indicator shows it as full range. I am not able to call or receive call unless I reboot or toggles to aeroplane mode. This also happens automatically when I get a call while 3g is enabled. Is this a problem with my network or something with the cyanogenmod? Is there any tool available to check if anything is wrong with my phone. ?
Thanks in advance
I am using the international version of HOX+
Tried flashing the boot.IMG? How about a LOGCAT
I have flashed the boot.img. I am getting 3g when i reboot. But some times the network automatically switches to edge and my phone goes out of the network. I dont identify it till I try to make a call because the network range icon shows full range . then I have to reboot to fix it. This problem also happens when I get a call while 3g is enabled and then it switches to edge after the call is finished. And the phone goes off the network.
