Problem with 3G / HSPA+ - Samsung Galaxy Nexus

I keep getting Edge/2G only data . My cell phone provider inform me if it's possible to toggle a switch to stay 3G / HSPA + only data like the other samsung galaxy variants. Sorry for the noob Q , i'm new to this forum . Any info is very much appreciated.

Open the dialer, dial *#*#4636#*#*, go to "Phone information", scroll down and under "Set preferred network type:" select "WCDMA preferred", press back button two times and restart your phone.
If you are still not getting the 3G/H icon in the corner of your screen, call your provider...
I did and they did something and told me to remove the battery and restart and then I got the H icon again.

Who is your provider? Maybe you used up all your allotted high speed data.

2G mode and 3G mode only

I've noticed in the menu options, there is an option to keep the phone in 2G mode only. On the other hand, is there any way to keep the phone in 3G / 3.5 / 4G mode? Any software that can do this?

The phone will only switch to 2G if faster speeds are not available. The 2G mode option allows you to prevent the phone from switching to faster (and more battery consuming) data connections....
From the dialer, you can type in *#*#4636#*#* to bring up some "secret" settings. From there you can configure your phone to only use 3G.

How about if I don't want 2G at all and want it to stay 3G only, even if there is no signal? I remember this option on the SGS 2..

You do what chrono just said and the hidden menu let's you force 3g only. *#*#4636#*#* on the dial pad.

Go into phone info. From there if you scroll down a bit you will see a text that says something like "GSM/CDMA auto". Press that and you should get a drop down menu. Change the setting to "CDMA only". That should work.

Not sure how that disables 2G (1xRTT). Unless I'm mistaken, both 1xRTT (2G) and EVDO (3G) run on top of CDMA.
Also, you can get to this from settings->wireless & networks->More...->Mobile Networks->Network Mode
There you can select LTE/CDMA or CDMA.
And it always sticks

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

[Q] ATT Note on Tmobile network

Hi
I have a ATT Note 2 with a t-mobile sim in it with ATT rom/modem/etc. The HSPA worked for like 2 minutes and never worked again. 2g works fine.
Has anyone gotten 3g/3g+ working one ATT note 2 on the tmobile network?
I know note works but couldnt find an answer for Note 2.
Please advice!
Thanks
^^^^^^ 2nd this.
ready to acquire GN2 ATT from local CL. but since i use t-mo cheap 5gb data plan, i am not sure how to benefit the plan. just a thought, you said HSPA worked for 2 mins (or so..) ? did you do any browsing/data usage and get result ? or just monitor the signal bar switching from H+ to E ?

Did you tried flashing a T-Mobile ROM??
yes didnt work either..
@ vish :
another shoot in the dark, do you think it has a relation with the phone being unable to toggle to 3G / UMTS mode ? will you please flash the t-mo radio back and tried :
1) With phone on, take off back cover and press your SIM card so it releases from the spring. It won't come all the way out as it's blocked by the battery. This seems fine - I didn't bother trying to force it out as I didn't want to break anything...
2) Once you see the message that the SIM card is removed, go to the dialer and dial *#2263#
3) You should see a menu with band selections. The current setting is "Automatic". If you switch to "GSM All", you will be EDGE (2G). If you switch to "WCDMA All", you will be on HSPA+ (3G, though AT&T and others call it 4G).
4) Press the SIM card back into place until it clicks. For whatever reason the phone will not recognize it until you reboot. Upon reboot you should see your new setting in effect.

so with jedi ROM x 6.1.2, 4g signal stays intact ? can you please do speedtest & post it here ?
btw : this 4g signal, supposed to be H+ in t-mobile ? or is it just UI issue ?

Sorry for the late reply - i tried flashing tmobile model and I got either bootloop or no service. Even with the sim card out.
Any other ideas?
Are you sure you are in a refarmed area? Cause if not you will ONLY get EDGE
^^^ what he said. T-Mobile is refarming their network to be compatible with AT&T's 3G frequencies but only in certain cities right now. Check their website, it tells what cities. They may be testing in your area. Otherwise you'll only get edge because the note 2 can't do what the note 1 did. It's an exynos thing.

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
Click to expand...
Click to collapse
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.
Bump
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

[Q] Is there any way to force HSPA/turn off LTE?

I get horrible LTE reception at work, and I know that my battery is paying a heavy price. HSPA on the other hand is great (4-5 bars usually).
On my Galaxy S4 I'd open *#*#4636#*#* and open up the device info and change the Network Type. But, the Nexus 7 doesn't have a dialer. Is there any other way to force HSPA on the nexus 7?
You can install ICS Dialer for example, enter your service code and get into the service menu. I tried, it works.
Yup, that worked perfectly. Thank you!

You can actually do this without having to install anything, though the app might make switching to and from a bit easier:
1. Go to Settings
2. Connections (tab)
3. More Networks
4. Mobile Networks
5. Network Mode
6. Change the network mode between LTE/WCDMA/GSM (for LTE) and WCDMA/GSM (for non-LTE)
