[Q] Captivate Unlocked, How to scan networks manually and set n/w to 2G/3G?

Hi,
I am using Samsung Captivate(unlocked) in India on Airtel's network.
Under 'Network Operators' menu, phone displays a read-only setting called 'Default Setup'. there is no way I can scan network manually.
this is problem for me while I am roaming. while roaming, I want the setting to be 'manual' so that I can hop onto my fav network.
usually(in any other phone), there would be a setting to set the network to manual or automatic mode.
other problem is that, there is no place to set the network mode(i.e 2G/3G).
are there any tweaks I can do to enable these settings on Captivate.
I am on JH7 update with out any kind of root.
Thanks

You would have to type in the apn fields manually then. Unless theres a secret menu somewhere which I haven't found yet. Oh and for the 2g 3g theres multiple threads on the q and a section about that
Yay no more fc

This is for me who came back from Dubai and found my stupid captivate would not connect back to AT&T network.
I could not chnage the network as "default setup" was greyed out and phone gave continued warning could not connect to etisalat ( dubai provider).
I found out through a lot of hard searching that I needed to use samservmode then
DEBUG SCREEN > PHONE CONTROL > NETWORK CONTROL -> PLMN AUTO/MANUAL set to AUTO
That fixed it and got me back on AT&T

Thanks for this thread.
i just returned from Nigeria and much to my surprise in Atlanta I couldn't get the
AT&T network back on.

doesn't work
I tried the app and it's not working. But for some reason AT&T is back on the air.
So I'm OK for now but can't get the Default Mode to turn to automatic.
Anything else i need to do to phone so SamServMode will work. Or am I not saving the changes properly?

[Q] Mobile Data Issue!

Hey there! I have a Verizon Galaxy S3 running Cyanogenmod 10.1 nightlies. I was just sitting there watching tv, I picked up my phone and saw that my service bar was empty and had a little "R" over it. I tried using the phone and there was an automatic answer saying "Welcome to Metro PCS. You are not a registred customer". WHAT?? I'm on Verizon with a CDMA/LTE radio. As far as I know there is no HSPA radio in my phone. I restored back to a nandroid backup I made on new years eve and that did nothing. So I flashed a new radio and now instead of calling at all It reads "Mobile network not available" and the little "R" is gone, but the service bar area is still blank! What do I do?
Edit: Flashed the latest nightly and new gapps, and now 4G seems to be working, but the phone crashes every time I call anyone, and no texts can be sent through or received.

Here's what you should do. Go to: Verizon Galaxy S III Android Development --> Sticky Rollup Thread! (Are you in Panic? Look here)--> [Tool][Win] Repair IMEI & Roaming ERI issues and follow the directions in that thread. It will send you back to stock, but once you're there you can start from scratch and be in the clear! Hope this helps! :good:

Did you flash a Metro PCS nightly instead of the verizon version (d2vzw/sch-1535)? Also did you... settings> more> mobile networks> and change CDMA Subscription to RUIM/SIM and System Select to Automatic then reboot?

Help request: LTE Data works,"no service" otherwise. IMEI/number, but no texts/calls.

Software: Android 5.0.1 Skydragon M8 v2.0 Sense 7
Many people have posted issues with LTE where their cellular signal was fine for "2G" functions like calls and texts.
I'm having the opposite problem. After leaving airplane mode (landing at an airport today), I have a "No Service" message in the status bar drop down (notification tray), and the Settings>Network information page shows "Not Registered." However, I do have an IMEI (see details below). However, LTE data works perfectly fine.
I've obviously tried changing the settings in Settings>Mobile Data (preferred network to Global / LTE / LTE/legacy 3GPP mode) connection type global/auto/LTE/etc), to no avail. If LTE is connected it works flawlessly, but I cannot make calls or texts, and show not registered on the network. Data roaming is set to deny, but even allowing roaming does not change the situation.
Before this happened, I HAD gone through all the XTended Settings, and even 'looked' at (but did NOT change) some advanced settings pages, including the 'hidden' HTC network info page ( *#*#4636#*#* ). Again, however, I didn't change anything -- unless by accident?!
Does this sound familiar to anyone? Anyone know if I may have inadvertently changed something and can change it back (a setting that would persist in the hardware through NANDROID restores and factory resets...). Or, any other advice to restore the cellular service connection to normal?
I've tried a full NANDROID restore (multiple times) to a working copy, and a factory reset. I have limited access to a PC since I'm traveling, so re-flashing the VZW firmware or stock recovery or lollipop/verizon RUU would be challenging.
I did spend a good 45 minutes (at a library, my only PC access!) searching the forums and web, but to no avail.
Settings information:
OPperator Name: Verizon
Signal Strength -114 (I've had better but still have the same issues)
Mobile Network type: LTE
Service state: In service
IMS service state: Not Registered
Roaming: Not Roaming
Phone Identity page:
IMEI shows up (15-digit number...how can I verify I didn't mess this up?)
Phone Number is correct
IP Address: 100.66..... (looks good)
Any help is GREATLY appreciated!

I'm having the same issue. When i try to make a call my LTE bars drop to nothing and it says call failed no network available. Any ideas or help would be nice. I was using venom rom as well. I'm currently trying to flash the newest RRU to see if that resets things. I'm wondering if it somehow my sim card. I took it from my droid turbo. I've made sure to turn off advanced calling on my VZW account though.

I had this same issue, running from ruu then rooted. I didn't noticed until I started seeing voice mail notifications but never heard the phone ring. When I tried to dial out I got the immediate call lost message. I couldn't figure what was causing it so I just did a reset. I made sure not to restore any systems data from prior to the Lollipop upgrade. At this point everything is working, the only thing I haven't installed yet is the xposed framework and sense 6 toolbox.

What kind of reset did you do? I know my issue is slightly different, but I did a full RUU-flash yesterday (latest lollipop version) and still no luck. Unfortunately I'm out of the country now and access to a computer is limited, and I don't even have a SIM card yet to check if cellular service would work anyway.
I do intend to do a flash of the stock recovery and radios once I have the time and access, but that may be a while...
Still, I'll keep checking this thread to see if anyone posts any other options

Just go into settings and to Backup & Reset , this will return your phone to a fresh install and remove all non bundled apps.
Before doing the reset try going into Settings then Call then change Preferred Network to Global, or toggle from LTE then back to Global.

Can't turn on data using the Verizon G5 on AT&T?

I just bought a used Verizon LG G5 (VS987), however my carrier is AT&T. After putting in the Sim card, calling and texting works but when I go to turn on mobile data in the settings, I get a popup that says "Add Mobile Service Please contact Customer Service at (800) 922-0204 for assistance."
I have called both that customer service number for Verizon ^ and also AT&T. I made sure that my IMEI was updated on our AT&T plan, and I have the right APN settings put in. When I called Verizon, the guy didn't really have much to say except that the device is unlocked but full access to features can't be guaranteed, and I am aware that Verizon and AT&T use different wireless bands, which he explained, but I should be able to at least have some kind of data. We both agreed that this is just some piece of Verizon software keeping me from using data, and he suggested rooting the phone to get a workaround.
One suggestion that I saw in some forums and tried was that resetting the network settings in Backup and Reset does turn mobile data on by default, however I get the same Verizon popup as soon as I open any browser, and other apps just say there is no connection, although when I do this I can see that I am getting either HSPA or 4G data, it just seems like it's being blocked by this Verizon stuff. Messing around with other setttings such as Data roaming and System select didn't change anything.
Does anyone have any experience using a Verizon G5 on AT&T? I saw a video of someone demoing T-Mobile 4G data on the Verizon model, and another user on XDA said that he put in his T-Mobile sim and it worked perfectly. My best guess on where to go from here is to unlock and root, and see if I can install a custom rom to get around this. Does anyone know if there is a stock LG rom without all of the Verizon bloatware installed, maybe a stock rom for the unlocked model of the G5? Any suggestions on how to get this to work are appreciated, and I think this is posted in the right place, I'm an active reader on XDA but this is one of my first posts
Thanks to anyone that reads all of this!

Update: I reset the phone to factory settings and set it up with the sim card from AT&T in it. Since then I can turn on mobile data, and the notification bar shows I have data (mostly HSPA), however I have no connection when I try to load a webpage. Tomorrow morning i'll stop by the AT&T store and see if there's anything they can do.

Did you add the correct APNs for AT&T in the phone when you put in your sim? you need it for internet and MMS
Did you which it to Gobal or other option that is not LTE/CDMA?

Same problem here

Was your problem solved? I'm having the same problem with another Verizon LG Device. If it was solved, what did you do?

Lg g4 h810 works 2G only

Hi,
I bought this phone Lg G4 h810, it shows AT&T logo whenever i boot it and the problem is despite of network mode on lte/wcdma/gsm/auto it always runs on2G internet speed and shows E sign.
I am from india and many service providers are still not offering4G internet service. But this phone doesn't even runs on wcdma. My previous phone lenovo was nicely running on wcdma and always showed the sign H.
My cellular operator is idea cellular and i had a word with them, they sent me settings and all and help me input the settings manually too, but nothing worked.
I checked even the frequencies, idea cellular is offering UMTS B1(2100) and UMTS B8(900 gsm). I checked this on LG website and these bands are compatible with the phone i bought, but still i can't get anything more than2G. Why so?
Plus there is one more problem, when i switched it on for the first time it showed update available And when i tried to update, it showed error and now always there's an icon on top left corner of phone saying couldn't install system update. I tried restarting and updating the device many times, but it's still the same.
Any help is much appreciated.
Thanks in advance.

Have you put your Company APN?

Yes i did, the company executive even helped me to manually save the settings to run the internet in a 3G mode. But all efforts in vain.

Did you solve the issue?

Anything new? I have the same problem.

I have this problem too

Try hidden menu with *#546368#*810# and under Field Test menu / Modem settings if there is VoLTE on/off chose VoLTE and restart. I have done that and my phone starts working with 4G. Don't forget to set up good APN if it's not automatically set by network provider.

Hi
Under VoLTE there is another entry named "Session" and in there
RPR(on/off) switch
I enabled it and restarts but it is again on 2g
Anyone further on this issue??

I have this problem too
I was flash the stock firmware,custom firmware customizing the build.prop,changed the settings in the engineering menu *#546368#*810# disconnected volte,changed LTE bands forcibly. Nothing helps,dont work 3G LTE - 2G only(. I realized that I need to re-flash (change) the original QCN file for H810 and re-register IMEI , but I can not find QCN it freely available.

Hello there, i had the same issue. The fix that worked for me was searching for network manuallly and reconnecting again to my carriers LTE network. Worked as a charm. The issue maybe was a brutal handover as I had been travelli g from a city to another one 200 km away. So somehow I had been disconnected from the LTE network and left stranded in the 2g one. Try it it should work
