[Q] GSM network mode - Desire HD Q&A, Help & Troubleshooting

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.

[Q] Change preferred network order?

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.

Mobile Network mode GSM/CDMA confusion *#*#4636#*#*

Entering in the "secret" menu *#*#4636#*#*, i noticed that the default network mode is GSM/CDMA auto (PRL)
Aren't two completely different networks (and phone)? Or what that CDMA setting is referring?
Since my GNext is GSM and in my country there is no CDMA network operators, is that the best option regarding the battery life?
I remember that in my previous htc desire, the default network mode was WCDMA preferred (WCDMA different from CDMA), even if i was using GSM auto (PRL) which mean that if the 3g is low it will use the 2g network...and i remember there was nothing about CDMA network
So my doubt is why the Galaxy Nexus GSM doesn't have GSM auto (PRL) or WCDMA preferred as default option? is that a bug?
here a reference about the network mode http://www.google.ie/support/forum/p/android/thread?tid=6a327a95211ac789&hl=en
GSM = GPRS (2g), EDGE(2g), UMTS(3g), WCDMA(3g), HSDPA(3g) {Cell Carrier examples: AT&T and T-Mobile}
CDMA = CDMA*(2/3g) EV-DO(3g) WiMax(3/4g) {Cell Carrier examples: Verizon and Sprint}
Now that the general stuff is out of the way, here's my take on the Preferred Network types:
WCDMA preferred - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 3G is favored more.
GSM only - The GSM phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
WCDMA only - The GSM phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM auto (PRL) - The GSM phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more. This one is a bit confusing to me since PRL is associated mostly with CDMA technology and not GSM technology.
CDMA auto (PRL) - The CDMA phone is capable of using both 2G and 3G data communication and when signal strength is low 2G is favored more.
CDMA only - The CDMA phone is capable of using only 2G data communication. When the 2G signal is too low you get nothing at all.
EvDo only - The CDMA phone is capable of using only 3G data communication. When the 3G signal is too low you get nothing at all.
GSM/CDMA auto (PRL) - Some phones are equipped with both GSM and CDMA capabilities. This setting appears to just have the phone attempt to stay connected to the data communication type that works the best.

Id like to know why the options dont stick as well... Just seems stupid to me that they dont stay after you choose them.
I have also been wondering the same thing. On the Nexus One and Nexus S it would default to WCDMA prefered and if I were to force 3G on it then it would stick on a reboot. On the GN if I put it to WCDMA only or GSM only it will revert to the GSM/CDMA auto (PRL) network type. It did this on stock 4.0.2 and it's also doing it on CM9.
In that menu there is something about LTE ram dump too. Is there a little more ram the LTE guys are getting that's hidden on GSM?

GSM auto (PRL) won't stick but WCDMA did for me but I REALLY regret changing it. It caused my SMSC number to change to 00 and I couldn't change it back on my GNex. It took me a while to figure out that the SMSC had changed and it stopped me from sending text messages but I could still receive them. After wiping and flashing a few times I realised and I put the sim card into an old phone and changed the SMSC back and put it back in my GNex and it let me send texts again.

God it was a nightmare yesterday. I did a google search and found the number on vodafone forums for my country. What's your carrier? Even if you have the number maybe you won't be able to put it on your nexus like me but you can try. Another possible solution might be to get a new sim card but I'm not sure if that'll work. I just read it online.

Mine is greyed out too so maybe that doesn't change anything in this case. I guess your best bet is trying to put the sim card into another phone and set the SMSC number on that phone then plug it back into your GNex. I used an old blackberry

Glad to see it worked. I actually went back to stock and rooted again and flashed AOKP and all that just to fix this and then realised all that wasn't necessary lol. I wonder if everyone switching to WCDMA only is having this issue or just us?

SMSC update
for refenrece about the above problem updating the SMSC i found this link
http://community.windmobile.ca/windmobile/topics/nexus_s_smsc_advanced_menu_options
its for the nexus s, but it works also on our galaxy nexus
so basically with our nexus (also other samsung i guess) through the advanced menu *#*#4636#*#*, u can update the SMSC only putting the encoded value like described in the link above
also the important things are the 2 buttons near the SMSC field:
- the first on the left (nearest the field) mean refresh: basically should load ur actual SMSC (sometimes don't work)
- the second on the right (far from the filed) mean update: so it change ur SMCS with the actual value on the field..so be carefully if the field is empty
(in my language the translation of those button are wrong, and both have the same label..thats why im explaining it )
anyway i suggest to don't play with the *#*#4636#*#* menu at all, unless u have problems
hope this helps some future users
I need help. Im in the US on AT&T. Im having the same problem sending sms. I can receive them but just cant send them. I think i messed up my smsc. Messing around with*#*#4636#*#*.I dont know what to do. Im running stock rom. Can somebody help me and tell what number need to put in. Im kinda lost. Gsm galaxy nexus in the use on ATT

[help] problem with mobile network in one x

Hello
I have a problem with my one x, it does not capture well the mobile network, while on another one x and others smartphone that captures very well the network
I gave him a flash with ruu last updated 2.17; May I always the problem
So I wonder if this is just a software problem that I can adjust itself, or it is a hardware problem and that I should return the phone in this case to the dealer
thank you

Some roms and some versions come with the radio configured to WCDMA only, meaning that it will only connect to 3G and HSPDA networks, most phones are set to WCDMA when available and GSM when not, so the phone skips from one to another depending in signal strengh.
in settings go to mobile network, there should be an option there called network mode, see if its set to WCDMA only or GMS/WCDMA Auto.

I inserted my sim in a friend's phone in the same area and 3G was working fine. I went to Htc Sales and Service Store but they simply said they can't help! I have never rooted rooted my phone and done nothing with my phone except downloading apps from Google play! Can anyone tell how to solve this problem??? Please tell the solution in steps because i am unaware of android development and stuff like that!

Did you get 3G while choosing WCDMA Only?
If Yes,means you have to do it manually everytime you reboot your device.
If No,means you don't have a 3G data plan.
If you reboot your device mean while it will again set to prefered WCDMA so everytime you need to do it manually. Just to remember if you're getting 3G even on prefered WCDMA then leave it as it is. I think it's an issue regarding weak carrier signal.

Its not the build prop. Its how HTC designed the DHD.
The DHD isnt quadband, You can check the specs at gsm arena.
Some countries have thier 3g on a different band, so if you buy a DHD that doesnt scan for 3g on your countries band, you face the same problem.
I have being trying to fix this problem but got stuck along the way. Its very good to see that people also have the same problem. Maybe the devs would try something.

Nope..
Before i can try anything i have to put the device in diag mode which i have being able to, but the problem now is the device isnt showing up properly in QPST(a program for communicating directly to the qualcomm chip).
It detects the open port on windows but its unable to find the phone in the port.
If the phone doesnt show up in the port, changes cannot be done.
So thats the update.
If you have any idea, you could share
WCDMA
goto mobile network under settings, then select network mode, change it to GSM/WCDMA auto if it doesnt work then change it to WCDMA only.
It'll do the trick.

[Q] Change 3G band to European GSM 900/1800

A family member gifted me a Galaxy S4, however it is the SGH-M919. I currently live in Europe and 3G bands in my region are GSM 900/1800. At the moment I can't access 3G and any other type of data for that matter (LTE is not supported here). Is there a way to change T-mobile 950 and 1900 bands to my region ones?
Thanks for taking your time to answer
Sadly not.
Since the radio does not support those frequencies for hsdpa

Hello Flex,
I have the same phone "Samsung S4 SGH-M919 - Tmobile" and I live in Hungary, it works fine with me all you have to do is just to switch form WCDMA/GSM to any other option "like GSM only" then back to WCDMA/GSM as a kind of refresh and the 3G will work fine after that, you can find this inside Settings > More Networks > Mobile Networks > Network mode, but unfortunately you have to do this every time you restart your device.
There is also another alternative solution is to reset the Access point names to default, you can find this inside Settings > More Networks > Mobile Networks > Access Point Names.
to be honest I don't know the reason of this error, but try what I described and tell me if it works with you.
Good Luck
Well. I have the exact same phone and have tried several ROMs, either custom or stock and basebands also. Nothing seems to work. The very few users who reported it was working didn't provide much evidence of it. Even Wikipedia says no 3G 900MHz availability for this phone. A simple edit to NV 1877 values won't solve it. I've tried that too.
