Weird APN / 3G issue - Captivate General

hi,
I'm on day 2 of trying to sort out my wife's new Captivate, so would appreciate any help at all. Phone is rooted, unlocked and has decent signal, but I cannot connect to 3g.
I'm on Optus network via TPG (Aussie network). I've tried many APN settings, and I'm at the point where I don't think this is the issue (yes, I know this is normally the issue).
I tried going into *#*#4696#*#* and doing WCDMA preferred, and WCDMA only, made sure AUS radio band was selected and did 'Enable data'.... also no help
I've also made sure data is enabled on the sim/account. If I insert the sim into another phone, it works with 3G. So it's something to do with the phone for sure.
Optus' 3g info says "2100MHz frequency band. Enabled with High Speed Packet Access technology (HSPA)". So WCDMA is the correct setting I think.
To be clear, I've never gotted the little 3G symbol at all (or an 'H' symbol that I've seen someone mention). I first tried emulating my own Vibrant's settings exactly, which didn't help.
Any ideas would be great.
thanks.

I'm completely out of options ... is there a chance this is an issue with bad contacts? I fixed my Vibrant's GPS by prying up one of the contacts...

All fixed. If anyone else has this trouble - flash back to stock, following this guide http://forum.xda-developers.com/showthread.php?t=884364
Note - I already had stock, so no idea what the hell was going on, but whatever.

'Bands' tab and Advanced config questions

I've searched the forums for an answer to this and I've found partial answers. I'm hoping I can get a response that will work for me.
Firstly, in the 'Bands' tab, I'm looking for some clarification on the options available. Under 'network type' there is 'Auto', 'GSM', and 'WCDMA'. Auto, I understand. GSM I'm assuming means GSM network (T-Mo, AT&T and not CDMA). WCDMA, according to Wikipedia, is basically the network that allows 3G speeds over GSM networks.
Now, when I set the network to GSM, I get an EDGE icon in place of the 3G. When I set it to WCDMA, I get 3G, as well I should.
First question: If I set the network to WCDMA, will it force my Fuze to ONLY connect to 3G? Where I live, I'm finding it hard to find a 3G dead zone to test without traveling 30 miles...
Second question: Does forcing 3G only improve battery life? I read in one post there are separate radios for 3G and EDGE/GPRS (which makes sense as to how you're able to talk and use the data connection simultaneously) and by forcing one, the phone doesn't constantly scan for the other.
My third question has to deal with having my device automatically disconnect the data connection after it finishes its business. I read in several posts that 'Advanced Config' has an option to set the data timeout, but I've read through the menus several times and have seen no such option. Are there multiple versions of advanced config floating around? Barring that, could someone just tell me what registry entry to add/edit to set the timeout? I read in yet another post that the phone automatically disconnects after 30 minutes, but that doesn't seem to be the case, as I tested mine and we're going on over an hour with no connection drop. (No email is being checked and weather is disabled. Prior to me starting this particular data connection, the phone had been connectionless for almost 16 hours.)
AdvancedConfig/Menu/More settings/Connections.
There is also that option in DiamondTweak.
WCDMA means 3G only, which means that your phone isn't searching for GSM signal. I haven't noticed battery improvement when forcing 3G, although that would be logical.

Foreign Carrier Data Connection Issues [Solved]

Hey guys, I recently unlocked and rooted my Infuse 4G from ATT
Im currently living in Panama and using CLARO, I got the correct APN settings,and everything, and the internet works.. "Sometimes" I have gone to the store to obtain help incase it was something on their network, but there is nothing wrong with the network, Next I tied Replacing my sim into my friend who just got the Galaxy S 2, And it worked fine.
The problem In my case seems to be That I cannot maintain a stable Data Connection, It keeps dropping and activating back randomly, if I reboot the phone it will bring data back to it 75% of the time.. but only for a short period.. maybe 5-10 mins at most, then it disappears again.
Im just wondering if anyone that is using the Infuse 4g in a foreign country has or is experiencing a similar issue, or if anyone can explain why this is happening and if there is a way to fix it.
Im waiting for Infused to come back up to put gingerbread on the phone and hopefully fix this issue.. but I fear it will require more.
To answer my own question I found a solution and testing a second
**Just want to add when I say toggle Softkey, I mean the button to the far left at the bottom**
Solution#1 to get Infuse 4G DATA working on Claro Network Panama:
Goto phone type *#*#197328640#*#*
Goto Debug-->PHONE CONTROL-->NETWORK CONTROL-->BAND SELECTION-->GSM BANDS-->GSM 1900-->Toggle Soft Key-->back-->toggle soft key-->END
This will give you a stable EDGE connection on the Infuse 4G
I will post a possible 3G fix after I have tested the setting for more than a day.
OK so Im pretty confident I got the 3G working now, if you experience this issue of losing Data on the network in other foreign countries to USA/CANADA this might help you out aswell.
**Just want to add when I say toggle Softkey, I mean the button to the far left at the bottom**
So again goto phone dial *#*#197328640#*#*
Goto DEBUG SCREEN-->PHONE CONTROL-->HSPA CAT CONTROL-->HSDPA DISABLE-->Toggle soft key-->Back-->toggle soft key-->END
If you followed my steps to gain access to EDGE you must do this also
DEBUG SCREEN--> PHONE CONTROL --> NETWORK CONTROL -->BAND SELECTION --> AUTOMATIC --> TOGGLE SOFT KEY --> BACK--> TOGGLE SOFT KEY --> END
so that you can access the other bands for 3G
Hope this helps people.
Also Would like to Add that Im using INFUSED v2.0.4 http://forum.xda-developers.com/showthread.php?t=1220088
and I switched to the ROGERS MODEM http://forum.xda-developers.com/showthread.php?t=1173704
With these settings applied.
The other way around this is if you install the Infused ROM it'll give you the option to manually lock to the network. The AT&T ROM has ATT roaming partner preference built in... super annoying, but is what it is. I had issues where putting in a foreign SIM I could only attach to networks AT&T had roaming agreeements with even though it wasn't an ATT sim and the non-ATT stock ROM solved it for me.
I saw network locking also in the debug menu, is that what you are talking about?
I cannot find any network locking within the normal menus.. if there is could you guide me to it please.
well I tried the lock via the debug menu.. and did not work when I enabled HSDPA.. maybe the issue isnt a foreign carrier issue or combination of a foreign carrier or just the fact that its a carrier that offer 4G but only on contract.
I was speaking to a friend last night, and he said when he was in the US he was experiencing a similar problem with ATT and the people at ATT said the phone will experience these issues on networks that have the ability of 4G or the HSDPA+ higher speeds since we know that its not real 4G.. so the phone attempts to connect or do whatever it does to obtain those higher speeds of HSDPA+, but is being refused by the network because you need to be on contract or have it enabled.. which then in turn causes it to disconnect all together from the data network.
So it made sense to disable to the HSDPA in the scenario.. I might add that by doing this on CLARO you do not get the full 3G experience its slower from about 2Mbit down to .50 Mbit but its still better than edge. and the HSUPA works fine with a 2Mbit Upload.
Im going to obtain a contracted SIM today with 4G enabled.. and remove all the steps I listed above to confirm that this is actually case.
I will post my results when I get the chip.

[Q] Rogers APN Settings/CM7 Data Switching

I am having the data switching problem (stays in edge - wont switch to 3g/4g) on my Infuse when I install CM7. I have seen the 1 APN suggestion to fix this issues with AT&T but was wondering if there is a similar solution for Rogers.
as a work around I tried switching my preferred networks from WCDMA preferred to WCDMA only (i live in Toronto - so no issues having access to 3g/4g network at all times) but it reverts back to preferred, data switches back down and gets stuck in edge.
I am having the same issue. All I am getting is edge.
I have a nexus one though.
It only just started though. Probably within the 2 or 3 days..
Not sure what's changed
Same here.
It only runs on Edge. If I put my N1 on 3g, it works intermittently. Only when it wants to, and even though it shows it as being connected, it is not, as text messages come in hours later, and calls go straight to voicemail without showing anything on the phone .
I checked the APN settings, called Rogers, they confirmed all my settings were correct, but still, nothing.

[Q] Network mode cannot set to 3G

Just got my Nexus 5 today.
However, in Wireless&networks / Mobile networks / Network Mode, I can only set it as 2G or LTE but not 3G.
I am currently on b-mobile in Japan and my Nexus 4 works fine on the network.
Wondering is it some sort of bug of KitKat or is it somewhat related to the SIM card I am using...

Probably the sim card. Mine gives me the option, but another n5 on a different network (o2/UK) doesn't.

hmm, in my case, I can see the 3G option, just that whenever I select the 3G option, the system would automatically reset it when I navigate to other page.
Is that also the case on your N5 with O2/UK sim card?
On the other hand, I will test my N5 on different sim card tomorrow.
I have the same issue. If I select 4g, the dot stays when I go back, but I only get a full bar 2g connection. If I select 3g and go back, no dot is there but I only get a 2g connection.
Sometimes this was solved in previous handsets by going into the service menu and selecting 3g/2g from there.

I also tried forcing the N5 to use 3G only (by going into the test menu with "*#*#4636#*#*" code) but it still does not work...
OK, so I tried the SIM cards from my colleges, and my N5 can connect to 3G without problem.
It's weird that my SIM card works perfectly well on N4 but NOT N5...
Did not experience such SIM card computability issue before...

Works for me now. Went into that test menu and selected GSM/CDMA auto PRL and I now have 3g. Didn't have to reboot.

I am also having the same problem, purchased the Nexus 5 from carphonewarehouse, can set on 4G or 2G, but when i set to 3G and comeback, it resets. Is that a SIM card problem? I tried to go on testing mode and apply GSM/CDMA auto PRL, that also not working. Is that a KitKat bug?
Same problem on Orange/EE in the UK. I can see the 3G option but phone won't let me change to 3G. Option never sticks. Just stays on 2G. Any ideas? Is this a known bug?
Thanks 101

i think it's not a bug.i think it's a hardware problem. i'm having it with vodafone italy.
Same here on T-Mobile Austria :/
Already changed SIM card, without success. Maybe provider related issues?

I'm on straight talk TT&T with a new SIM card, but sometimes the network mode doesn't stick. No idea why...
replaced a new 3G SIM, no luck
Just replaced a new 3G SIM Card didn't work the 3G option for me - Chunghwa Telecom Taiwan.
But I can select 2G, and dial number to make a phone call, so the SIM slot seem works fine, maybe just configuration issue?!
And, also I find a very annoying defect of my Nexus 5 32G(White), when hard-reset or flash to Factory Image, my Nexus 5 32G white goes crazy!! it just keep stuck and loop at Google Logo (not even show the 4 circle animation), and won't boot at all!
And I finally find a way to make it boot, by keep trying repeat flash factory, erasing userdata, erasing cache etc. is every had this issue?
EE/T-Mobile (uk) and I can't select 3g either, well I can but it doesn't stick.
I have a similar problem, except I can only select 3G / 4G, and not 2G because the 2G option isn't even displayed!! So infuriating. It still works through the *#*#4636#*#* menu, if I select GSM only then it does indeed go to 2G.
Is it possible that the SIM is somehow telling the phone OS it can't do 2G only? This didn't happen with my old carrier (same phone, only just switched). I have a feeling it's caused by the same thing that makes my phone number show up as 'unknown' now, too.
I have the same issue, I tried two different SIM, on is a Straight Talk sim that is set up to use the ATT network and used a T-Mobile sim card, both were unable to keep 3G as a setting.
My Nexus 5 seems that reluctant to drop from 3g to 2g when 4g is selected i have given up and now just manually select 2g to make sure i have a signal (im out in the sticks a bit). Sat at the PC with 4g selected i get no signal whatsoever, with 2g selected i get an indicated full signal strength.
Why on earth the N5 is so reluctant to dip its toe in the 2g territory when no data is on is beyond me.

Please help! No 3G or GSM, can't call, but LTE works fine.

I really need help with my device, I searched all over XDA and no-one seems to have the same issue as me.
Here is some information:
1) Nexus 6P (H1511)
2) 6.0.1 Absolute stock, no rom, no root, no custom recovery. Build number MMB29P.
Recently got a new Nexus 6P and imported to Russia. All of the major bands here are supported. And the phone worked excellent for a few weeks, but then it lost all 3G or GSM connectivity. Just randomly,didn't do anything with it, the only thing I did is move to another city but than I got back, the issue didn't resolve. LTE works perfectly but can't call or receive calls, can receive sms though. Reseting network settings and factory reset changed nothing. Tried manualy set network to WCDMA or GSM with *#*#4636#*#* command, the moment I switch to anything besides LTE the connection is lost. Contacted the provider, no problem on their side, my SIM works good in other phones, my phone with other SIMs - no.
I don't think it is a hardware issue because a few times I managed to get everything working after an hour of switching networks and bands with no particular order in the *#*#4636#*#* testing mode.
After a while I figured that if I set phone to "GSM only" on USA bands in testing mode, but at the same time set it to "LTE prefered" in the normal network settings menu. I am able to set phone to Band mode 7 and set the network back to 2G in network settings keeping it on " GSM only" the whole time and only after this compicated algorithm and after a reboot 2G and 3G starts working. But any reboot after that revertes everything back to only LTE stage. Also if I get everything working but than reset network settings everything stops working again.
I have no idea what caused such an issue, I really hope someone can help.
Sorry couldn't post screenshots because of the "10 posts rule".
