Hi everyone,
I have a d2vzw running Carbon ROM Kitkat. I spent the weekend back in the UK and enabled global mode, which connected to Vodafone's GSM/HSDPA network using the original Verizon SIM. So I had phone and SMS service - no problems at all.
However, I couldn't get a data connection. It was connected to the HSDPA network (enhanced 3G). Under Settings-->More...-->Mobile networks there is the option ("Access Point Names") to choose an APN. However, none showed up. I tried to add an APN manually, but as soon as I set Vodafone's MCC and MNC, it refused to save the APN info.
Oddly enough, the correct APN settings are all on the phone in Carbon ROMs "apns-conf.xml" file, they're just not showing up.
I tried everything to remedy this, but no luck.
So, here are two questions to harvest your collective wisdom:
First, is there a solution to this? I like Carbon ROM, but I have to have global data access for my work. If I can get my d2vzw running Carbon connected to international GSM networks and APN for internet, then I'd really like to.
Second, does anyone know of a KitKat ROM that DOES do this properly on the d2vzw?
Thank you so much,
M
I haven't checked in on AOSP ROMs in a while, but last time I did, none of them could do this, you need to run a Touchwiz-based ROM. AOSP ROMs like Carbon use a reverse-engineered radio interface which is not quite as good as the Samsung one which is included with TW ROMs, and this is one problem with it.
The bottom line is that if you want all the hardware features of your phone to work, you have to use a TW-based ROM, because Samsung hasn't opened up the hardware.

Thanks, Jacquestrapp. That's helpful. Perhaps I will flash a TW-based ROM and then keep it as a nandroid backup for when I go travelling.
I have been using my Verizon S3 in the Philippines as an international phone for months with excellent service. I am able to connect to the GSM network and transmit data at H+ speeds. I am on CM 10.1.3 official on Baseband MF1 and have been able to successfully switch to GSM using the PhoneInfo app. To assign proper APNs, I use the HiAPN app. Be very careful with Phone info: I once broke my connectivity messing with the settings too much ("Select radio band") and had to revert to Twiz and turn on the GSM bands using the "secret menu" to turn those back on. If you have a Twiz backup, try dialing *#2263# to choose the bands your phone has access to (seems impossible on other ROMs) if you keep having problems.
The thread here (see post 106) is enormously helpful.
The info about Twiz and reverse engineering is useful -- I haven't been able to get reliable service beyond CM 10.1.3 (very low signal, inability to send SMS, but somehow can receive SMS and voice calls), so I have been sticking to 10.1.3, unfortunately. I want to upgrade to 4.4, but haven't been able to do it without breaking GSM functionality. Has anyone gotten GSM and data to work on a 4.4 ROM?

My phone acts weird on the network mode 'gsm/wcdma(automode)'
It works perfectly when I select 'GSM only'. This means that I have the APNs right
But as soon as I select the automode so that I can use 3g, phone starts acting weird. For starters the internet does not work. I also lose my voice service. The bars show that I do have voice service, but on making any call the call doesn't go through, and on ending the call the call remains on the notification bar. But if I dont end the call, then it does eventually shut by itself (~15secs) and then the bars disappear and I lose service. At this point my phone has automatically gone into flight mode. On turning flight mode off... the cycle repeats (with some exceptions):
1.notification shows service coming back: 3G, full bars for voice service. (Sometimes 3g doesn't appear at all, and at this point internet does not work but I can make calls)
2.but internet does not work (but if I keep trying it might work for a few seconds. Noticed that because network mode is on auto. Notification bar shows switching to GSM, and then back to WDCMA. On repeating this the internet lasted longer ~a min or two)... and then doesn't start at all (basically its very random)
3.make a phone call and call doesn't got through, lose service and goes into flight mode
I use an unlocked rogers samsung captivate on fido network (unlocked phone on network that share the same bandwidth). I also use a custom ROM: firefly 3.0. Specs are:
model number: samsung sgh-I897
fireware version: 2.2
basband bersion: I9000UGJK4
kernel version: 2.6.32.9
I have gone back to stock rom, and even back to the custom rom I upgraded from (pheonix 4~). I have tried different modems and a lot of ROMS. I am willing to repeat it all if its necessary
Please help. I've spent over a month trying to figure this out. And relying on gsm just doesn't cut it. It would be great if someone could even point me in the right direction.
Is this a phone, sim card, or service provider issue?
I believe this is a service provider issue...do you know what bandwidths their 3g is broadcast on? The captivate can only pick up 850 and 1900 if the frequency is outside those it will not connect.

I use fido in canada which broadcasts on 850 and 1900. I do connect to 3g, but it is only briefly. But then I lose 3g and also my voice connection.And my phone goes into airplane mode automatically! My voice service (bars are full) is consistent when I am on GSM. This is independent of the ROM I use. Why does this happen? What is the connection between 3G and voice service.
based on *#0011#
ECIO on 1900 ~ -8
ECIO on 850 ~ -12

When the phone is on 3G, voice will also use the WCDMA signal instead of GSM. So, if your phone is on 3G and it can't connect, you will likely lose the voice as well.
Some Canandian carriers have separate APN for 3G and GSM. So, just because your phone works fine in GSM mode, doesn't mean your APN is correct on 3G.
Then, some custom ROMs based on EU i9000 ROMs can't handle 850 band at all. So, you need to be careful with what kind of modem is loaded with your custom ROM.
Looks like a kernel issue. Firefly is supposed to include Speedmod kernel and it looks like you have the stock Captivate kernel which I recall does not play well with anything other than a i897 modem. I use to run across the same problem (no voice in calls even though I had signal) when I first started messing with modems/kernels. Flash the latest speedmod kernel and see if that works.

make sure that your modem and kernel are compatible. The KB1 modem will not play well with a I9000 based kernel.

I made some assumptions and just included the kernel version. Ive never messed around with kernels. I am using the one that came with firefly:

This is really odd. But my phone is fixed. 3G is working and I have no idea how. I went through my usual application download and install cycles. The only system apps that I incorporated were a cache cleaner called 'history eraser' and a service starting app called 'autostarts'. And my phone is back to normal. Something to do with freeing system resources. Anyone have any ideas? I would think Samsung would need to fix this.
Hopefully Im not speaking too soon. But in the past two months this is the only time when my 3g has worked more than 10 mins
like I thought. I spoke too soon. After a reboot, the 3g stopped working. But it does not act as oddly as before: going automatically to flight mode and my voice service works even when the setting is on gsm/wcdma(auto).
Please help. Anyone have any ideas?
If this doesn't miraculously fix itself again, I am going to reinstall everything for troubleshooting puposes. I have to figure out if this is random or if autostarts,cache cleaner and any other app makes a difference
voodoo lagfix
I read somewhere that the voodoo lagfix changes the file system and the kernel. Could this be the reason why I cant connect to 3g
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.
Hi,
I have a galaxy skyrocket i727 from AT&T with last Gingerbread firmware(2.3.6 from at&t).Now i am in india.Recently i did a factory reset and now i have lost data connectivity(though i get full signal and can do calls or messages).
Even before i used to select frequency bands manually to swap between 2g-3g by dialling *#*#197328640#*#* and i used to get data fine.As there is no such option of selecting 'gsm only' or "wcdma preffered/gsm" in wireless&networks menu of the AT&T Firmware.
So the main question is if i put the unofficial ICS ROM like AOKP or UCALC4 than will i get this 2G to 3G selection in settings?Will the phone select indian frequency bands automatically?
thanks!
You may have lost your apn and that's why you can't get data, check under settings mobile network apn if there is anything there(I think that's how it goes in GB) if there isn't check your provider's site or call them and ask how you should configure it.
About your second question, it depends on what rom you will flash, some support it and some don't.

Thanks for replying!
My APN is ok.I requested new apn after deleting older ones and even did a manual "Add new apn" perfectly.Thats why i am asking this question ,because there is no reason for getting "no data".Everything is perfect except that there is no "E" or "H" symbol with up-down arrows beside the network strength bars!
Stupid question but did you enable data?

yeah dude!Obviously!
enabled - disabled it several times!rebooted after selecting apn etc etc But no good
Well sometimes we ignore the obvious so I had to ask. Check your apn again to be sure, make sure the internet apn and not mms apn is checked if you have 2, and it's defined as internet or internet+mms in case of one combined apn.
If this wont fix it something must have happened in the factory reset and you should try upgrading to ICS and see if it still works.
Hey.. BTW I have a question for you , how did you unlock your phone yo use it in India ? I know there are unlock codes, just curious if you got it from at&t or you had to go the eBay way ?

- You need to be SIM Unlocked and have a RAT Unlocked Radio (HINT: Roger I-727R radios)
and
- You need a ROM to support those, if you using TouchWiz I have supported this always from the beg. im my
ROM (see my sig.)
And I do travel there once a quarter, no issues for me. I have an IDEA Card and it works perfect, even ROAMING to 3G where IDEA piggy backs on other providers..

when i initially read your name ,i guessed you were indian!
Thanks for the reply.I just flashed the sk8erwitskil,s Latest Cyanogenmod 9 with UCLF6 libs just to check if i was able to switch radios,but right now i am in "2G/gsm only" area.Data is working fine,but cannot turn on wifi...it keeps saying "turning on".
My phone is sure sim-unlocked on idea network,and on UCLF6 Modem(is this thing same as a "radio"?).Initially i was on stock at&t GB firmware.Btw ,which place in india do u travel?
If wifi error persists i will flash EMBRYO Rom
I have a rooted ISW13HT (HTC J by KDDI in Japan) and I can switch to the HK radio for traveling overseas and unlocking the sim, however for mobile operators who require an APN, it doesn't work in the default ROM. For whatever reason, in the default version of the ROM (I'm still running 2.05.970.3) there is no option to edit the APN and it seems that KDDI has probably disabled it as it seems to be included in every other ROM version that I read about or tried. Currently when I travel I'm loading the HK ROM and using that since it has APN settings but this is far from ideal and I would like to just use my home ROM 100% of the time. I have to use the Japan ROM at home because of the Osaifu Keitai (Felica) function which seems not to work on other ROMs, or at least the Mobile Suica refuses to work on the HK ROM saying that the OS isn't supported and that is an essential function for me to use the train everyday.
I'm sure there has to be a way to edit the KDDI ROM to re-enable the APN Settings function, could someone lead me through this or point me in the right direction. I've tried searches and nothing turned up for me.

Wanted to bump this and see if anyone has come up with a solution yet. It's been quite a while since I asked before.
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!
Same here
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.
