Service code not working - Galaxy S II Q&A, Help & Troubleshooting

Hello everyone!
Today I've activated the mobile data plan, but H+ is draining lots of battery. I've heard that the code *#301279# can disable highly power consuming HSPA, and force to use slower but more battery friendly UMTS (3G). And the problem - after entering this code in dialer nothing happens.
I'm on XEO XXLQB (ICS 4.0.4) stock Samsung firmware, rooted and on SpeedMod K3-31 kernel. What can be wrong? The system app "Service mode" is not disabled. Some other codes are working, but this one - not

I wouldn't suggest using the codes to do things with your phone. I hear that you can change Fast Dormancy from Off to On (It did not seem to do anything on my phone), but that is not just 4G to 3G or 3G to 4G. There should most definitely be a third party app (or widget) that allows you to adjust 3G and H+ from stock rom. I've seen them before. I don't use stock (so I always have an option to change to 3G if I want, but I know that you can finda third party app (or widget) to do so. You're welcome

Try the following:
- Dial *#*#4636#*#*
-Select phone information
-Under select network type, choose WCDMA only
Problem solved!
Let me know what happens
Swyped from my Samsung Galaxy SII

After changing it to "WCDMA only" phone sticks to HSPAP only, when the signal is very low it disconnects from network and doesn't "go lower" to 3G/EDGE.
I want to lock phone in GPRS/EDGE/3G and completely disable HSDPA etc.
Method using *#301279# was great, I've checked few hours ago under Android 2.3.x and it worked on it, but on ICS code's not working.

[Q] Data not working after ROM installation.

Hello guys I think I have a problem. After installing this (CyanogenMod 7.2-cooper-KANG-RC0-Android 2.3.7) my phone's data capabilities like 3g is not working anymore.
I am using the baseband S5830DXKT5 (2.3.6) from SIngtel. However, after flashing (before I install cm 7.2) I tested the 3g and I connected to the internet and it was fine. But when I install this ROM, my data capabilities fail.
I have the proper internet settings that my network provided me.
I have a signal and Messaging works. I can also browse the internet through wifi.
Help?

Did you manually enter the APN settings and press the circle ?
No, the settings was already there. I tried to manually change it but the parameters are already the same as what people in my country suggested.
The circle is already toggled.

im using CM7.2 as well but does not have issues.
Since CM 7.2 there is an additional settings included in the Wireless & networks
1.Mobile Networks > Network Preferences
> now there is an option to select WCDMA only, WCDMA Preferred etc.
> ensure you select WCDMA Preferred if you want 3G
> or WCDMA Only to forceit to always use 3G connection

Found this in the other tread.
I had tried it and it still doesnt work.
I also read the whole tread and to no avail, my data connection still does not work.
Ive tried using different baseband versions and different roms.
Whatever baseband I use, the 3g and data connection works. However, once I install any rom there is, Ive tried three (Kang, Ice Cream Sunday, CyanoAce), I just lose 3g and data connection.
can anyone help?
Now basically i also had the same problem... Intially wen i flashed CM version my DATA nor 3G working.. Later called up my svc provider they told to delete the OLD APN and he guided me thru the whole process of putting new APN.. Viola a restart my DATA came back May be u can try this once...
This was an issue for Telcel in Mexico when the upgrade to 2.3 came to Galaxy Ace, the fix was changing the Radio file (to a latin american one) but in this case is all zipped and i don't know if this can help actually.
Just a stab in the dark, try turning on data roaming... worked for me... with Grif's CM 7.1 with an unlocked Galaxy Ace not running it's native SIM. Worth a shot?
Maybe its your APN setting
If you're using globe, they have 3 or 2(not sure) different APN for postpaid and prepaid subscriber.
for postpaid I think its "internet.globe.com.ph"
for prepaid its "http.globe.com.ph"

Can you explain further? I think this maybe the issue because my unit was not bought here in our country. It was bought by my dad in another region.

wow this actually worked.
thanks a lot man!
---------
so for people the will encounter this kind of problem in the future, here is what apparently happened.
Globe (our Network Provider) sets the default APN to the postpaid instead of the prepaid one when you install new ROMS.
to think that this may be this simple. ive researched changing CSCs to flashing different basebands and roms.
case closed!
No problem. Glad I helped.

[Q] How to force Samsung Galaxy GIO to stay on 3G ?

I am using GIO as wireless access point for my notebook, but in 90 % of cases when I am calling someone or someone is calling me it automatically switches to 2G and of course dropping internet connection.
When using it as AP its always connected to charger.
There is no option in stock rom to make it stay at 3G , there is only option to force 2G.
Was trying to uncover "secret" menu using "any cut" application but no luck with it.
I am using stock 2.3.4 Android , was trying 2.3.6 but there is no option to force 3G either.
I saw there is such menu to force 3G on SGS2 / SGN but not on GIO
How can I force Samsung Galaxy GIO to stay on 3G while talking with someone ?
It could be that GIO not be able to hold both, 3G and phone connection at the same time if you calling some one...Im not sure

It could hold both at same time , because sometimes it stays on 3G when talking and using it as AP, so have internet and can talk normally, but there is some stupid default setting that tells GIO to switch to 2G most of the times.
Dial *#*#4636#*#* -> Phone information-> WCDMA only.

[Q] S3 Lose Network Conectivity

On a regular basis (at least once a day), I lose Network connectivity.
The Upstream/Downstream arrows disappear, but I still have 4-5 bars.
Happens Indoors & Outside
Applications report no Network available.
I don't have any power saving apps that disable networks
Android Power saving is disabled.
I'm on 4.1.2, (Vodafone Stock ROM, Unlocked) and this has been happening for a while - from ICS 4.0.1, I believe.
I switched from T-mobile to GiffGaff (O2 UK), but I can't remember if this was happening before the switch.
Unable to make call ("Not registered on Network") when this happens.
Sometimes a toggle of the "Mobile Data" button works, sometimes toggling to "Flight mode" works.
More often than not, this requires a restart. Always fixes it immediately,
Other O2/GiffGaff users are unaffected, so not a network issue.
Any idea if this is an S3 issue, a GiffGaff (O2) issue (any other sufferers on different handsets), or a combination of both?!
Cheers
Sean (En_croute)
Ask your provider for a new SIM, might be SIM problem
Check your O
2 network coverage where its a problem .
You should also check you are using Giffgaff settings in mobile networks .

Setting changed earlier today (Proxy & Port details)
Still dropping off (this evening)
It's not a network issue (other users & instant restoration on reboot), so any ideas folks?
Are you using any power saving apps?

[Q] Data network keep changing between HSDPA /3g

Hello I updated my S2 to jellybean and the data network keeps changing between HSDPA and 3G. Making the use IMPOSSIBLE.
When I had the ICS there was a hiden menu *#301279# to disable HSDPA.
When I dial *#301279# I get somethin like "INVALID MMI CODE"
My phone is in spanish.
In JB I cannot get to this menu.
Is there an alternative to make it only use 3G.
Thank you

Strange it works for me, and I'm running 4.2.2

And it does not work.
Any ideas?
Thank you
Data network keep changing between HSDPA /3g (SOLVED)
I found the solution in this thread:
http://forum.xda-developers.com/showthread.php?t=1818661
Found solution:
First enter service menu via secret code
*#197328640#
In the menu, choose the following items sequentially:
1 (debug screen)
8 (phone control)
3 (nas control)
5 (rcc HSPA control)
And then you will find the well known menu to change the HSDPA settings
Thanks
With my S2 I9100 with OmegaROM V12, the code *#197328640# does not work
Any help?

Limited network selection in SM-G965N- no 2G option. Can i flash modem file?

I live in Bangladesh. I have SM-G965N Exynos single sim Korean KT mobile version with stock rom, latest update- non root. Everything is smooth- my only gripe is- in the Mobile Network option, there is a preferred network selection dropdown but i only see LTE/3G only and 3G only. Nothing else.
I really don't need 3G cause most of the times, i am on Wifi and i don't use mobile internet. I really need 2G option- this also does improve battery life.
Any option i can try or ask a service tech guy to do so that i can get that full selection of network availability? My phone has one or two KT app which cannot be deleted. Any trick to just flash the modem file?
no one out there to even point me to the right direction?
