[Q] Change preferred network order? - Samsung Galaxy Nexus

I have a slightly odd requirement, and I wondered if there was any way to fix it:
My carrier has a partnership with a second carrier so we can roam on each others networks for no extra cost.
Where I live, my own carrier only gives me a 2G signal, whereas the other gets 3G. Thing is, I have to physically select the other network. If it's on Automatic, it always "prefers" my own carrier.
This is fine until I'm on the other side of town where the other network gets no signal at all. I then have to manually select my own carrier again!
Is there any way to get it to prefer the other network, or even more ideally, prefer the one that offers the better signal at any given point?

Hi,
a bit of *bump* because I'm struggling with the same issue. I had such option on my previous samsung i780 (oooold) and it worked like a charm.
Currently my mobile operator has 2 roaming partners and if I want to change quickly the preferred order (because in some location it might have better coverage but only there and only for a while) I wold have to switch simcard to the old phone...
Isn't there at even a separate aplication to do that? Does andorid API allow such modification?

Glad I'm not the only one!
Interesting you mention an app to do it... i've not looked actually. If an app can access the list of networks and actually set the phone to use one, then I guess it would be possible. I'll check it out...

to the best of my understanding this is somewhat network option/setting and when suggesting an app I was thinging abount some way to read this setting, modify it and then save/send back to network. It would be a matter of access to the network settings from the API and knowledge how to operate it....

Still investigating this. Looks like the stuff to access the list of networks is in some internal APIs, so a little harder to access. I'll post back when I learn more...

Hey I hope you guys can figure this out have you tried the *#*#4636#*#* command and changed the radio? This will select the most preferred network.. e.g. I'm with Telstra in Australia, the stock radio defaults to 2100MHz but Telstra's HSPA+ is 850Mhz.. so I have to switch to AUS2 radio so it defaults to that every time.

It's not about the radio band but about the service provider itself.

GSM Frequeny

I have a Orange SIM card which I got in Israel, I am now in Canada and that SIM works fine on my friends Nokia 6600, but when I try to use it with my XDA IIs I can't find any networks or anything. I am guessing its the GSM frequecy although the phone supports all of them. Does anyone have any idea what I need to do to get the SIM to work here? Does anyone know how to manually select a GSM frequency?
XDA IIs
ROM Version: 1.40.00 WWE
Radio Version: 1.15.00
Protocol Version: 1337.45
Hello psytech,
I believe you're roaming. Sometimes, you really cannot just plug your sim card then voila its working. If you are roaming, most of the time you really have to manually select the network.
anyway, i'm currently using windows mobile 2005, and no longer using windows mobile 2003 SE. i hope i could still help you or atleast you can see the pattern on how to do it.
here what you do:
1. click on the signal strength icon (the icon located on the upper right most portion of your screen just beside the speaker icon)
2. a dialogue box will appear with a clickable 'settings' button (located on lower left part of the dialogue box.), click the 'settings'
3. you will then see 3 tabs on the bottom part of the screen, 'phone', 'services', 'network'. click on 'network'.
4. you should find something like 'find network' button there, then just but before you click on it, choose 'manual' for network selection.
the rest is self explanatory, i hope i was able to help you. cheers!
You say your orange sim works fine on your friends nokia but does not work in your IIs.
Is it possible that your IIS device is sim locked as in will only work on the O2 network in the country you got it from.
If so unlock it via wiki (link in sig)
not it
I forgot to mention that the SIM worked fine in Isreal, my original SIM is orange (I do have an account with) I just can't get support cause I didn't buy the phone from them (capitalists).
About the network search. Thats what I've been doing for the last couple of days but I can not find ANY networks at all. which is what leads me to believe that its a GSM frequency problem.
What happens if you put your friends sim in your phone
GSM in Canada is generally 1900 http://www.gsmworld.com/roaming/gsminfo/cou_ca.shtml
doesn't work either
My friend's SIM doesn't work on my phone either. If canada is 1900, how can I make sure that my phone is currently using 1900. (I know it supports it, but how do I actually see that its actually scanning with it?)
What happens if you go to Settings->Phone->Network and then change Network Selection to Manual.
You should then get a list of networks. This will list all networks even if you cannot connect to them.
[edit] This has already be suggested earlier in the thread
If you do get some networks then the only reason that I can think of that you are not connecting is that under Prefered Networks you have a network selected that your carrier does not have a roaming agreement with.
Check your provider's website to see who they have agreements with.
no networks
My provider (Orange) has agreements with Rodgers, but my problem is that I am not listing ANY networks, I tried manual and even added the Rodgers network to my favorite networks, but when I try to search for networks I can't find any, I just get a blank window. This is very odd to me and I've never heard of anyone with that problem.
Like I've mentioned before, I updated my windows to TuMa 1.4 and my radio to 1.1.15. If there's anything else I need to do or anything I may not have done when I updated my network please tell me.
btw when I installed that TuMa windows I change my ID thingy to Tmobile.
Problem solved
Attenttion everyone:
It has come to my attention that there is a problem in the Band Selection CAB when it comes to certian cellular providers.
The problem so far appears on a Cellular One network that only supports 850Mhz. When the North American Option is choosen in the Band tab, the phone can not find a network to register on. I'm not quite sure why this happens yet, but there is a solution to fix.
http://relaysgoldens.com/sx66/ext_roms/BandSelect-fix.CAB
By installing this CAB, it provides a fourth option on the band tab, "Reset Value to Zero".
By selecting this option, the phone will be reset to it's default state, and will work normally.
I've trapped this as a bug in the 1.40.124 extrom and will be working to figure this out.
Note: the band selection setting is persistant, and will not be reset even if you downgrade the ROMs on the phone. If you are experiencing this problem, the ONLY way to reset the value is to use the CAB above.
-Chris
P.S. I've also updated the 1.40.124 RAR file on the website to include the updated bandselect CAB.

3G possible with Three Mobile PAYG?

I'm using their PAYG sim which gives a free 150mb allowance for 90 days, but am only ever able to connect via GPRS (my phone says I am roaming as well for some reason). Is anybody else using this sim and able to receive 3G?
yes indeed.
Three don;t have the 3G coverage of the other networks, and so they use Orange as a backup network when you are in an area that does not have any of their own transmitters. Seems you might be in such an area, which is why it says you are roaming cos you're actually on Orange!
Make sure you are not stuck in 2G only mode of course.....
dial *#*#4636#*#*
select phone information
slide down to the bottom, abnd make sure the first menu box is set to WCDMA preferred, and not GSM only.
Thanks for the information, thought this might be the case but wasn't sure. The phone was already set to WCDMA Preferred so I guess GPRS is the best I'm going to get from Three Mobile for the time being.
Thanks also for letting me know how to access the testing screens, lots of good info there!
no probs, here to help.....when i'm in a good mood and not at work of course

[Q] GSM network mode

I have noticed people managed to change their network mode to GSM only mode??? How do you that?? I only have 2 options: WCMDA and GSM/WCDMA auto?? Is this thing vary due to your courier?? Currently I am with 3 Australia. I wish I have the option to switch only to GSM. From experience, it can save you a lot of battery.
If you don't have the option then you can't pick it. I don't know if that means it's been removed or if it's simply because 3 don't offer a 2G network service (GSM mode). They probably have some 2G sharing but only in spots without 3G so you still have the GSM/WCDMA auto mode.
That's the best I can offer since I know that's how it works with 3 over here in the UK where they have only their 3G network. The firmware likely has GSM mode disabled for that reason but wait for more to back me up or prove me wrong.

I have a feeling it could be the ROM or firmware that comes with it has it disabled the GSM only option. My Desire HD is the UK version. I am not sure if the other Australian version (from Voda or 3) have that options. With my original desire (and also using 3), I have that GSM only option available. So I dont think it's because 3 doesnt offer 2G network.
Get Advanced settings from Market. You can set it to GSM Only in the phone information menu.

Thank you for sharing..yes, it works....but I will try out and see if it does save a lot of battery life.
Type *#*#4636#*#* in the phone dialer to get to testing menu. Under phone info you can set different options that are not otherwise available. No app is required.

Thanks for the info. I have tested both method...both work. But the only problem, how do we set it permanently?? I mean I have noticed every time you reboot the phone, the setting changes?? and I have to set it back to GSM only??
but even if you could technically switch it to gsm, would it actually make a difference? surely if the actual mobile network is pure 3g and no 2g, then switching on the phone wouldn't change a thing? as its not actually possible to use 2g on 3 network?(because they built network from scratch out of 3g is what they always boast about anyway..)
This is strange. I have an unbranded bought sim free HTC sensation here in the UK which Im using on the 3 network and I dont have the option under network to set it to gsm only. This option should be here on an unbranded handset, and its there on my old Desire which was also bought unbranded sim free when Im using that on the 3 network.
Anyone shed any light on this? I know the work arounds mentioned above, but Im more interested in why the option is missing on my handset.
Cheers
PS I know this is the Desire HD thread but its the only topic I could find on this subject so far.
I don't think it matters, just don't even bother with the settings menu for that in the first place. in the Testing menu just set the radio to either GSM Auto (PRL) or GSM Only. GSM gives more talk time.

WCDMA / GSM auto problem

Hello Guys,
I'm experiencing a problem with my Froyo Desire for probably a week now.
The thing is that in certain areas my Phone can not receive calls / sms or such. In other words "GSM services" dont work. 3g though works fine (stable, strong and fast connection) My Provider is T-Mobile.
After quite a lot of testing I was able to isolate the error:
When WCDMA / GSM is chosen by the phone automatically it seems to me as if it didnt switch "back" to register with my provider via GSM when i want to make a call or if someone wants to call me.
When i switch to "GSM only" manually everything works fine but i have no 3g of course.
I also experience this problem only in certain areas. I live in an area where there is really strong HSDPA available (up to 7mbit\s). When i go to other places of my city i still get HSDPA (not as strong) but calls / sms still work.
The last paragraph may be of no importance, i don know.. probably it helps..
I have googled quite much about this problem and also found a few persons experiencing the same issue but nobody was able to come up with a solution.
I would be very thankful if someone could try to figure this out.

gsm only Desire?
I'm having a nightmare with 3g 2g connectivity on my Desire on the three network whilst at home. If I could manually select gsm only this would be fine as I could still call and text and use wi-fi. Unfortunately my options are gsm/wcdpa (or whatever) auto or the 3g only.
can someone please advise if it is possible to select gsm only and if so, how?
many thanks
Can someone please advise me how if possible, to set the desire to gsm only?

Wireless and network-Mobile network- should be here somewhere.
Thanks, but there is no option for gsm only. It's wcdma only or gsm/wcdma auto. there has to be a way around this.
Similar problem, different version
I've experienced similar problem.
In some area, I can get steady grps signal when I switched GSM only on; but when I switched WCDMA/GSM on, I could get no data connection at all.
I'm using China Unicom's mobile service.
Solution
Hi there,
I've the same issue and I fix it allowing the option GSM/WCDMA Auto in the configuration menu.
Then enter the following code *#*#4636#*#*, select "phone Information" and set preferred network type, set "GSM car (PRL)".
Sorry about my bad english.

[Q] Mobile data is stuck on "G"

I have finally acquired a data plan from my cell provider, and today I set up the APN settings for it. However, whenever I turn off the wifi, I only get the "G" (GPRS) icon in the status bar, with unbelievable slow download/upload speeds.
I just now tried flashing my radio to Radio_12.28e.60.140f_26.04.02.17_M2_SF (Even though I believe I had it before as well), and still I can't get it up to "H" (HSPDA).
I asked a co-worker with a Galaxy S on the same cell provider, and he has HSPDA speed at the same location as I. I also compared his APN settings to mine.
What can cause this error? Should I try flashing a different radio? is the Radio_12.39.60.19_26.06.04.06_M or Radio_12.35d.60.140f_26.06.03.24_M2 better in any way? Are they stable? Is this even the cause of my problem?
I have moved this question from the "Android Development" forum (sorry) - and over there I was told to use
*#*#4636#*#* -> Phone information -> WCDMA preferred
or
*#*#4636#*#* -> Phone information -> GSM auto prl
I tried both options, and when I tried "WCDMA only" I got disconnected, when I use any "preferred" setting, I get "Network type: GPRS".
I checked with my co-worker, and he has "GSM/CDMA auto (PRL)" - trying that I am still stuck on "GPRS" as my network type (He has "HSPDA" on his network type)
Are there any other hidden locations I need to check, in order to finally get HSPDA?
where did you buy it?
there are different "versions" out there with different frequencies.
"G" (GSM) is available in every country..but EDGE, UMTS, HSDPA, etc have different frequencies..that could be a reason why it doesnt work.
DN41
I have ordered my DHD from France, but I believe it came from Spain, according to the English (Spain) and English (Catalan) languages on it.
Where can I see what frequencies it support, and how can I change it/fix it?
I just checked. The DHD is
Europe:
HSPA/WCDMA: 900/2100 MHz
GSM: 850/900/1800/1900 MHz
Both Israel and Spain (And France) is on 2100, so I think it should be OK...
seems that this is not the problem
if it would've been the wrong "revision" with different frequencies, you couldn't have done anything.
seems like a software problem...does other sim cards work?
DN41
Try
Settings, wireless and networks, mobile networks, network modes.
This give options for WCDMA only, GSM only and GSM/WCDMA auto.
Hope this helps.

you might also want to check you have a 3G capable sim card, if you have only just aquired a data plan
Someone once told me there is no such thing as 3G sim - they are all basically the same, except for the on card memory size (64/32MB, or something like that). I wasn't too sure he was right, but then my cell provider just told me he can give me the data plan, without the need to physically upgrade the sim card. Then again - what do they know?
Do you think it might be the case?

Yeah, pretty sure there's no 3G SIM card. The SIM card only identifies you to the network.
Yes, it was the sim card. Apparently mine was quite antique... Now it works just fine with H/3G.
Thanks for the help, though.
