[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

same here
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] [Solved] APN settings USA AT&T GoPhone

Hi
I am currently in the US for holiday. Bought two prepaid att go phone cards already in Germany and activated them. The Data connection in my wifes SAMSUNG SIII mini (stock) works as it should.
In my HTC ONE SV I only get EDGE working. No matter which APN settings I use as soon as I switch on something else as GSM only in Network data plan.it disconnects completely from Mobile and states "Service not available"
My SV is unlocked and rooted and running with the Russian ROM
Any quick suggestion what can help,
Edit: I went to a AT&T shop here. They were very helpful but couldn't get it working. Tried more things and at one point all APN settings were gone. After that I tried for the first time the "Reset to default" and it loaded the ATT Phone settings.
After a restart everything works. I have here with H sign in taskbar a download of 5Mbps and upload of 1Mbps.
I attach the screenshots of the settings

[Q] Android 4.3 update - APN internet settings not working (no mobile data)

Flashed 4.3 onto my note 2 and can't get any internet to work. I've followed the standard APN settings listed on the talkmobile website and geeksquad but still no internet?
CM 10.1 (4.2.2) had internet working fine but I can't get anything to work now.
A bit of googling has suggested that the APN settings in android 4.3 are different - there's MVNO type and MVNO value, but I can't find settings anywhere for talkmobile and customer services didn't know what I was going on about. Lots of people seem to have had issues but can't find a concrete solution for my network operator
Any ideas? Don't really want to have to downgrade since I had terrible battery life with CM 10.1, though I'll have to if I get internet back!

[Q] Modifying APNs with 4.4.2 (NE1)

Hello,
I've been putting off asking the question as I thought that somebody else had to have gone through this already but I've had poor luck looking through the forum and Google hasn't been able to help.
I'll be traveling to Italy in the near future with my Verizon Samsung Galaxy S3 (Build KOT49H.I535VRUDNE1). I would like to pick up a TIN or WIND SIM while I'm there, primarily for data usage. From what I've read, once I install the 3rd party SIM, I'll need to update the APN settings to get data to work.
Stock, it looks like the APN settings are uneditable. I rooted the phone with towelroot (if only everything were so easy) and then checked the APN settings to see if I could add another network. No dice.
Poking around on the web, it looks like in the past, people have been able to work around this by downloading build prop editor and adding the following two lines:
ril.sales_code=LOL
ro.csc.sales_code=LOL
I gave this a shot and was surprised to see the APN menu gone when I went back into my network settings. Through trial and error, I determined that the inclusion of ro.csc.sale_code=LOL changes my Mobile Networks options from:
- Mobile Data
- Global Data Roaming Access
- Roaming
- Signal Strength
- Network Mode
- Access Point Names
- Network Operators
to:
- Mobile Data
- Data Roaming
- Network Mode (GSM is not an option in here)
- System Select
- Dial Up Networking
There is no option to modify APN settings there. Am I missing something silly? Did something change in KitKat 4.4.2 that has caused this approach to "unlocking" the APN settings to become invalid? Is everything really ok and I'll have access to the APN settings when I insert the italian carrier's SIM card?
I'm game for other approaches as well. At one point, I thought I saw an article that talked about setting up a pointer to the APN settings prior to updating the prop file but I haven't been able to relocate that.
Any suggestions would be appreciated.
Thanks!
Aaron

In the event somebody else is looking for the answer, I got my hands on a TIM sim card today, installed it in the phone and the APN menu reappeared and let me enter a new APN. Looks like the answer as of today for this phone is TowelRoot, SuperSU, BuildProp and install the 3rd party sim.
Take care,
Aaron

Verizon Galaxy S6 G920V lost LTE and ability to edit APN

Hello all and thank you for your time,
I recently updated my Verizon GS6 from Lollipop to Nougat using the Verizon Wireless Software Upgrade Assistant because the update wouldn't occur using the phone's update software feature. Since updating I've lost the ability to use the LTE network by any means at all. I have no data whatsoever, as the APN settings have been altered through this update. I am registered to Straight Talk Wireless and the phone is trying to connect to Verizon using a generic APN. I'd love to change the APN setting but the phone will not allow me to edit anything but the name of the APN. Adding or editing further is completely colored out.
So far I've tried:
1. Soft resets
2. Hard resets
3. Wiping the cache
4. Swapping SIMS of all 4 networks
5. Turning Wi-Fi on and off Turning Mobile data on and off
6. Searching all throughout the internet for answers
So if no one has the answer how to fix this situation is it possible to reverse my update and head back to Lollipop? Is it possible to root the phone to somehow access the APN settings by other means?
Any help would be greatly appreciated as I need to use data for my job.
Thanks!
