[Q] 3g problems - Galaxy Ace S5830 Q&A, Help & Troubleshooting

Hello, i'm from Argentina.
I want to learn more about 3g connection.
When i try some ROMS from these forum, 3g sometimes works and sometimes not...
I always use the same APN settings, but it depends on what ROM i use if it works or not...
What can i do to get 3g fully working on every ROM that i want to try?

Go to phone dialler and write *#*#4636*#*# and go in phone info and select cdma only to get full time 3g...
This works on all roms (stock atlest dont know about CM )

Setting for using GSM only

im currently on valkyrie rom, and i wonder if there is a setting that allows me to only use the gsm net, not 3G for my xperia X1i, im experiencing poor signal strength at work.. please say there is and that it will work for me
Well, i've disabled 3G in Settings---> Phone
Then i also disabled 3G Data with "NoData" from MoDaCo http://htcdriver.com/index.php?page=nodata
Don't know anything about the valkyrie ROM, but i suppose you could do what i did.
In valkyrie you should have the option to change to GSM mode in CommManager.
i tried both metods, but i dont get any reception when i change the damn thing! probably my operator, im gonna call them

[Q] Milestone is loosing signal - hardware or software error?

Yesterday my Milestone dropped the network and wrote "Only emergency calls". On other phones there was maximum signal. After a while the phone logged in to the network, but lost the signal again. I thought something is with the ROM, so I made a factory reset but didn't help. I flashed the correct SBF file (first Éclair, then Froyo), but didn't help. I restored an earlier MOD I used without any problem but didn't work.
I always used the German baseband files with other MODs because my Milestone is German.
The problem is that if I make anything (I mean anything related to the data connection), the GSM signal disappears, sometimes data connection remain with no problem, sometimes it is lost, too, but sometimes it has GSM signal with only EDGE network. If I do nothing, just turn off the screen and do nothing, everything goes back to normal, and the phone has normal data connection with GSM signal, I can make or receive phone calls.
I put in another SIM but the issue was the same.
Can I try something related to software and didn't try yet or this is a hardware failure? And if so, what is the price of a GSM module? I couldn't find it.
MOD: It seems that only the 3G is not working (sometimes HSPA does while 3G phone connection don't), with 2G there isn't any problem.
dial *#*#4636#*#*
Under phone info, try a different network type.
It probably defaults to GSM (auto). It does on mine anyway and it's fine.
But maybe WCDMA preferred, GSM only, or WCDMA only will work better.
It depends on which is screwing up... the WCDMA or the GSM
edit: had the dialpad code wrong... again.. geez

Are you sure you have applied the correct baseband?
I would tell to re-apply thru AOR.
Sent from my Milestone using XDA Premium App
You could go to settings, wireless and networks and somewhere there there is use only 2g networks and if that is checked, you could try to uncheck it. That is what happened to me before on the froyo mod. Also, you could try turning on airplane mode, then turn it off. Good luck
I always used the German baseband, tried to switch 2G/3G many times, applied the baseband trough OR, applied the RTEU baseband, re-flashed the ROM, the original Éclair, the Froyo, again and again but nothing helped. I gave up I decided to go to the service. Before that on a forum somebody asked something, I gave an answer but I was not 100% sure about it, so I flashed the RTEU Froyo.
And it worked. The 3G, HSPA, 2G, EDGE, phone functions all are working now. My phone is truly German, it has QWERTZ keyboard and the original ROM was the ROM from Deutsche Vodafone (tried that one before, too), it has the logo on its box, and the German baseband files always worked. I don't know what just happened, it's simply working now. Why now... don't know.

[Q] Only using 3g connection on hd7

hi everyone ,i'm a new user .
as title i make this question.i often connect to internet by 3g connection.i went to setting/mobile network then i set data connection: on,3g connection: on and my country APN.My Hd7 work well ,but only "use 3g connection when availale". it almost switch to 2g network
Anybody have ideas to solve it ?it really really necessary for me
Sorry for my bad English,hope you understand my problem
Go to the dialer. Type ##3282#. Go to settings, under 'Network Type', choose 3G only. If it's already on 3G only (I think it moves back and forth between 2G only and 3G only while on Automatic mode), change it to 2G only, then back to 3G only. This will keep it on 3G only.
thank you very much.i solved it
hello friends I have a t-mobile hd7 but I'm from Colombia, they know how I can make it work on 3G network here in Colombia because it only works on 2g

[Q] 3g problems nexus one

hello every body
i have this problem with my nexus one when i am connected to 3g service (umts,hsdpa,Etc'). i can't make calls or receive any calls, i can't use the internet (data) or get sms and Etc'. but i have full bars reception. when i check the vi in setting to "use only 2g" the phone work great.
i tried everything downgrade/upgrade roms,radios. i tried to go back to my first backup and even do PASSIMG but nothing help i googled it every where but nothing
please some one can help???
without 3g the smartphone is useless
thanks,
shushkis
What network you on? I would at least see how old the sim card is.
Lots of time if you have an older sim card it just can't handle a newer system.
I am connected through Orange IL
and i tried switching sims even with other networks.
and more the phone worked fine at the beginning it just happened i remember i switch to one of CY roms and it happened
Have you tried a full wipe and reinstall the rom?
yes of course i tried customized roms and stock roms but nothing helped
I would check your apn settings...
apn connected to taking or getting calls?
i thought it's just for internet connection
Its just a guess.
If its a problem on multiple ROMs, its likely to be either hardware or settings. Settings are cheaper and easier to test, and that's the only setting I can think of...?
Of course, doing a full wipe (including system), installing a new ROM, and testing before you restore any apps and settings may be another way to test, but since the apn settings are pre-baked into most ROMs, it wouldn't rule our the apn...?
OK I tried to put apn settings and it didnt help
you say hardware?
but when I check in settings "use only 2g" the transceiver works great .
maybe the nexus have two transceiver one for 2g and one for 3g?
seems un-logical
No there are two radios one for 3g and one for 2g because 2g is for calls and 3g for data but when 3G is unavailable the phone will use the 2g for the data.
The Same Trouble
shushkis,
I have the same trouble, my 3G connection works so bad, but if I use only 2g connection, all works good... I have no idea what happend with my N1. I have a N1 for 3G 850 (AT&T) model.
Thanks for advantage.
So maybe the problem is the hardware? if the N1 have two inidvidul transcivers?
I have also the same problem. I've tried many different roms and radios. I use 900/2100 3G. What's strang is that 3G works perfectly at home, but when moving to another tower I get emergency calls only warning. 2g works fine.
I just started having 3G issues at home. With 3G on the phone reboots like once an hour, but on 2G I've gone days without a reboot. My 3G signal is not the best at home, but I don't know why that would make the phone reboot. I'm on T-Mo USA.

The one I'm using is only a couple months old, and it works well in my Desire HD, and my Moto Defy. It's only the N1, but I guess maybe it could be that. I'll look into more.
If it's only a few months old, then it may nor be the SIM that is the problem. I suggested it because a number of T-Mo users were having similar problems after a recent network upgrade, and a new SIM seems to fix the issue for most...

[Q] How to save the "Network-type" in 4636 hidden menu

Hi,
I own a LG Optimus 2x (P990) running on stock GB with 0725 baseband. One major problem I'm facing with it is it keeps losing the signal completely. After researching online, I found out about the 4636 hidden menu (*#*#4636#*#*) and then changing the network type to GSM auto (PRL). This helped a little. However, the settings dont "stick". After few days, or sometimes, a couple of hours, they go back to WCDMA preferred which causes a complete loss of connectivity for me. How do I save these settings? I dont really use 3G as its not feasible in my region yet. Can someone please suggest something?
Why didn't you just change it at the settings menu under wireless & network? You can set to 'only use 2g network'.

I've tried that before going into the hidden menu. Same thing happens. After sometime, it kinda forgets that its supposed to use GSM and reverts to WCDMA
Happens to me too, i am on temasek's Kang, although it happens randomly and isnt that frequent in my phone so i dont worry bout it much.
Even its random for me. But when it happens, I end up missing calls and texts coz of it. Its soo irritating when the phone is unable to perform its basic functions correctly. I really dont understand why does the device revert back to WCDMA when i'm telling it to use GSM
Turn OFF and then ON phone.
Set to 2G only and save
Turn phone OFF/ON
I was just fighting against the opposite, I want it to be on WCDMA only but the config was resetting every time I restarted the phone or causing signal loss. A few minutes ago I matched the RIL with the baseband even with recommendation and it just worked!
