The T-Mobile G2 has *#*#4636#*#* to enter the diagnostics function.
Would there be anyone out there that could give me the best (performance) settting options that I should select with my G2 when in the diagnostic mode? Thanks in advance!

I mostly use WCDMA only. You also can downlaod AnyCut from the market and load the shortcut PHONE INFO and it will do the same thing as dialing those numbers

Also too, why do I use WCDMA only is for it only looks for HSPA+. That way if I'm say in walmart it does not go back and forth on HSPA+ and Edge all the time. If its not 100% HSPA+ than my cell won't connect and waste that little bit of battery roaming

If you're in a city with good HSPA or 3G coverage, use WCDMA preferred. If you're in a city with spotty 3G/HSPA coverage, use GSM auto (PRL). The first will connect to 3G/HSPA if at all possible. The second option needs to reach a higher signal threshold before it switches to 3G/HSPA. I've tested both.

I know this is a newb question but what does it mean when you see all of those numbers and symbols? Is it a number to call or text? I want to know because I say it under the OTA post in order to "Check In" but I have no idea what it means or how to use it.
Its basiclly a code to get into phone information on your cell

You enter it just like a phone call, then it will present the Phone Info menus to you. To checkin, it's the same sort of thing, just dial *#*#2432546#*#*
Hope that helps.
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.

@Simmo3D
It's not about the radio band but about the service provider itself.
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

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.

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
Hi all,
I was in Vegas a few weeks ago and LTE was killing my battery. I found the code to get to the menu that allowed me to switch it off. Embarrassingly, (or possibly not I mean I was in Vegas and may have been loaded at the time) I have since forgotten the code and can't for the life of me google it up again. If anyone knows what it is, I would love to get it from you. It looks like ATT just got LTE running in Denver and I would like to at least run a speed test. Anyway, thanks for helping.
this is not possible in the stock att rom.. they disabled those menu entries.. you can change your apn to phone apn.. to get only 3g/4g

Didn't you forget a #* at the end to make it *#*#4636#*#*
Figured it out
OK, I googled it out. The method that I used was *#2263# But this must be done with the SIM card released. That will take you to the RAT selection menu without any restrictions. There is a selection for automatic choice which will pick up LTE if available or WCDMA (all) for HSPA+, 2G/3G etc without LTE. Turned LTE on and the speeds were beyond ridiculous (47886kbps vs 6646kbps) but I could have lit a cigarette on the phone while watching the battery drain. Going to stick with HSPA+ unless I need to dl large files for some reason.
Something is wrong with your phone, I'm always on LTE and I get at least 14 hours out if it with HEAVY use throughout the day.

Follow up.
So after I figured out the LTE switch, I went ahead and threw CM10 on my phone. So far the battery issues are not nearly as bad. I assume that something was conflicting or causing an issue. Who knows? The performance is better and that is what counts. Thanks for the replies.
Change APN
The easiest way I have done it is by changing the APN.
