[Q] Radio and 3G problem - Samsung Galaxy Nexus

Hi,
I changed radio on my Galaxy Nexus two weeks ago. I switched to XXLH1 (the last one) and i think that since that time I have problem with my data connection. I cannot get H or 3G in my town. Only E. I didnt have this problem some time ago. Could be the problem in the radio? And if so, Is it good to try to switch to lower version? Thank you!

Dial *#*#4636*#*# then tap on phone information, check if it is set on WCDMA-preferred, not GSM-only.

Where shall I tap? When I tap on the icon of the little telephone to call that code, it says it is not valid.

Install the 'Network' app by Philipp Mangelow. It is a shortcut to that menu.

I have this same problem after upgrading to 4.2.2, selecting wcdma preferred doesn't help...any ideas

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.

In addition seems there is no way to change the network mode in that menu on my gnext, the option i choice doesn't stick

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

[Q] Why can't my GNex connect to T-Mobile 3G?

Hi everyone,
I'm reasonably certain that this isn't a redundant thread -- at least, none of the discussions I've read have helped me fix my problem. Anyway, here goes:
I have a new i9250T that I purchased through Amazon. When I got it, I popped in the SIM card from my Nexus One (both SIM and phone acquired in January 2010). Everything worked fine, EXCEPT that I could only connect to T-Mobile's 2G network (Network Type = Edge:2). After trying everything I could think of, I called T-Mobile, and the tech told me that my 2-year-old SIM card was 2G only and that I should update it. So I went to a T-Mobile store and got a new SIM. Alas, it doesn't seem to have worked.
I would REALLY appreciate any suggestions. Some additional info:
-- I'm in Philadelphia, in a very good coverage area.
-- I flashed yakju, 4.0.2, and UGLC1 radio before getting the new SIM.
Again, any thoughts will be appreciated. I've seen enough posts on various boards from people successfully using this phone on T-Mobile to not give up, but I'm out of ideas.
check what your APN settings are on your N1 and make sure that they ate the same on your GN.

Thanks. I'll check that tomorrow morning (I left the N1 at my office).

i too received my galaxy nexus today from amazon, i also only seem to be receiving EDGE service. The apn settings were enter automatically from the sim card i assume, and seem to be the same as my old Galaxy S 4g.What else can we try.

Weirdest crap... aren't the GNEX suppose to work with either GSM Carriers 3G? From what I read lol ...
- Google Galaxy Nexus
I get 3G/H with my Nexus. Running Android Revolution HD 3.0 w/ franco's kernel. Not sure if I got it before then running stock, though.
It should definitely work no question with little issue. Just pop in your sim and good to go. Maybe its some random network issue in your area that coincidentally started?
Same here, got it on Amazon. it's a GT-I9250T which means it's for the Australian market (I9250 International, I9250M Canada, I9250T Australia). I'm just stuck on EDGE, but works fine on AT&T - I tried it with my gf's sim card.
The problem is with the frequencies. T-mobile uses 1700 and 2100 (both! for upload and download), AT&T uses 1900Hz. The phone is supposed to be a pentaband phone that's able to work on all on the freqs besides others (850, 900). So my guess after a few days research is that it's limited in the software. Still researching the solution...
Let's keep each other posted on this, i'm eager to get my 4G back !!!
NEW DEVELOPMENT!!!
Information from another post: flashing UGLC1 radio helps. Good luck all
I had the same issues with no 3g speeds on any radios except a random docomo radio until today.
Based on a few posts in the baseband thread i tried the settings in the hidden menu
Go into the phone dialer and type
*#*#4636#*#* -This should bring up a testing menu
Go into phone info, then pull up the settings menu
There should be a select radio band button
Try the USA band, if that doesn't work, try automatic.
This worked for me, I've since flashed 4 different radios that hadn't worked previously and now do at standard speeds vs edge only.
Well my buddy bought his also from amazon and had the same issue as the OP. But luckily we got it fixed. I believe what he did was only tinker with the APN settings. Under APN Type in your T Mobile apn make sure the correct profiles are there. One of them could be data but I'm not sure as I'm on SIMPLE Mobile and my buddy is on T Mobile, sorry. If you get it working and your MMS isn't working, then add mms to the profile as well. That should do it. He did get his phone with 4.0.1 and I updated it to 4.0.4 Android Revolution 3.0 just like me as well but it wasn't until we tinkered with his settings did it work. Oh and we also swapped for a new SIM. Let me know if this helped guys. I'll try getting his settings if I see him tomorrow.
Edit: his was also an Australian galaxy nexus. But he seems be having everything working now

So ait this is the Australian version? They use 850 and 2100 bands so is it possible the other bands are disabled on that version?
Problem solved!
I took chimaki1's advice and fiddled with the radio band setting. I had done this previously, but I had always selected "USA Band." This time, I selected "Automatic." Closed out of the Testing menu, and -- bingo! The wonderful 'H' appeared and I was now getting real speed -- 7.9mbps down, 2.8 up. Not as good as some of the insane speeds I've seen posted by GN owners on T-Mobile, but a lot better than 100kbps down I had been getting. Also, I didn't mess with the APN settings at all.
To recap the solution for others having the same issue:
From the phone dialer, enter *#*#4636#*#*
Tap "Phone information"
Tap the Settings icon at the bottom right
Tap "Select radio band"
Select "Automatic"
Close out of the Testing menu (you can just hit the Home key)
I can't remember whether I had to soft reset or not; I don't think I did.
I hope this works for others. Thanks very much to everyone who posted.

This is weird. my galaxy is still not getting 3G/4G Service even after changing radio band in the hidden test menu.
Is your galaxy running the stock software, or are you running something different. if so, what rom are you running
It's running the yakju image and OS version 4.0.2. I flashed both using the WugFresh tool. The phone came with yakjuxw (I think) and 4.0.1.

Not "disabled" but more like they're set up to "prefer" the Australian bands.
I'm having the same issue on the I9250T I just got. Stuck on edge. I played around with the hidden menu settings, still no luck. I'm using a TMo SIM card from my previous phone which had 4G so I doubt that its a time/patience issue. Any help will be appreciated.

My phone has had "H"/4G access since day one, if I put it on US-Band I only get Edge. I put it on AUTOMATIC and it works fine, leave it on AUTOMATIC.
Today I tried a friend's ATT SIM and it worked fine with H/3G speeds. popped the TMo SIM back in and I'm back to EDGE. Wondering if there is something that needs to be done to the phone settings or, or I was hopping some one could tell me what needs to be done.. thanks

Tmobile S4 on AT&T cannot connect to LTE help!

Hey everyone!
So I picked up a tmobile s4 to use on ATT since I read it was the most unlocked due to bands / bootlocker. I unlocked it via the method described on this site via the debug menu.
Popped in ATT sim, everything looked fine initially.
1. I'm only getting 4G in an LTE area. device hasn't picked up any LTE anywhere yet.
2. When I go under "Network Mode" and select "LTE/GSM/WCDMA (auto connect) the signal dies out and it always reverts back to GSM/WCDMA"
3. I've called ATT a few times and triple checked that I'm on an Android LTE data plan, so that's not an issue. ATT techs suggested it could be a device issue and maybe I should take it into their tech center.
4. Tried to set up ATT Visual Voicemail, that failed also.
So can it be a Sim issue? Maybe something on tmobiles side? Since device was never active on their network. A lemon S4?
I've run out of options
Any help would be appreciated.
TIA!

LTE/CDMA in ro.radio.networkmode screws up phone.

Hi, guys I recently ran into an issue with the build prop modification in regards to network selection. If I enable the network selection as pointed out in one of the other threads and select LTE /CDMA my phone will lock on LTE however no phone calls can be made out or recieved. I had to reflash to 10k then reroot and then change the build prop to CA/TLS and finally hardreset via stock recovery. Anybody else have this issue?
UPDATE... looks like as long as i dont try to make a call the option to switch it back to auto is still there. One a call is attempted and fails the option to set to auto disappears.

Most carriers Phone calls and Texts dont go through LTE...... If your setting it to LTE only thats why.

I understand but after it's been on LTE for a while it doesn't give you the option to switch back.

Simple fix. Just select airplane mode for a few and then toggle it off and you'll see your network options come back once data roaming turns off and your carrier logo appears. I typically run lte/CDMA to get consistent lte speed bit when a callsade I have the same issue as you. But I just gave your the fix so your good

Stop changing it to lte/cdma and you're phone will no longer mess up. Leave it on gsm/wcdma/lte auto. You're phone will switch when the appropriate network is available!!!

Thanks a lot captain obvious, the point of the thread wasn't to "not switch it" dude, it's finding a work around and make everybody aware of what happens.

N7105 *#9090# default and LTE/4G question

Hi,
Need some assistance regarding a setting for the N7105. If someone could kindly input in their dialer *#9090# and tell me what the default settings are (please do not select anything). Then press back button to cancel.
The default settings are the ones with an asterisk in between two brackets, as seen here (*)
I accidentally selected
[1]DM/DUM over HS-USB

when checking out the service mode/diag config using the above dialer code.
On another matter, also in regards to the N7105. Has anyone noticed in Settings>About Device>Status, that their N7105's Mobile network type is consistently LTE:14
Reason being, is that when my phone is displaying that status, my signal bar shows only 1 bar. However, it does sometimes show full bars and the Mobile network type then displays 'UMTS:3'
I am in an area that can receive 4G signals (Sydney, Australia), but I was under the impression that my phone should be idle in UMTS:3 mode for general calls and SMS; and switching to LTE:14 when I activate mobile data and thus use 4G signal.
I am able to make calls/sms and connect to 4G with no problems, however am concerned that since it tends to be in LTE:14 mode the most that it may drain the battery more than if it were in UMTS:3
Thanks in advance.

Just dialing *#9090# won't change anything, so long as you don't touch any of the options. Simply dial it, look at the defaults, and then press back button to cancel/close page.
Thanks in advance to those who can help.
Mine is on HSDPA:9, i'm using the N7105 also.
Even if its using LTE band, as long as your not downloading data, it wont kill your battery.
Mine is
[2]DM/DUN over HSIC &
[5] DBG MSG ON
