I'm travelling in Japan now and I noticed something strange.
I have both "Use packet data" and "Data roaming" disabled in settings but for some reason "Data roaming" sometimes enabled itself!
I did some testing if some app turned it on and finally found out that checking for OTA update when using wifi enables Data roaming Very dangerous for your phone bill if you don't notice it Luckily I had "Use packet data" disabled so no harm done.
I'm pretty sure you have the roaming for that happen since the setting didn't change back in Finland when checking for OTA update.
nice info, thanks !
Interesting, by your statement, it should affect all of us whenever we roam. But I have been roam to other countries before, I did not notice such issue.
What is the ROM you are using? Stock or custom ROM?

You mean checking for a firmware update? If so why would you do that in a foreign country?

Well after many searches and a lot of trial and error, I think ive finally solved my problem of dropped/no phone signal for NAND builds, which in turn has also made my battery life way better since the phone is no longer constantly searching for signal Basically its 4 steps, ive tried each individually with no changes but for some reason when applied all together it works wonders. They are as follows:
1: dial *#*#4636#*#* and go to phone information and choose 'gsm auto PRL'
2: go to settings>mobile networks and check 'use only 2g networks'
3: go to settings>wireless networks>wifi>advanced and change wifi sleep policy to 'never'
4: go to app store and download "wifi keep alive" (free). choose wifi behavior 'always on' and advanced options 'enable workaround 2'
using these 4 steps i reduced my time without signal from 74% to 12% in 16 hours, and im getting 4-5 green bars all the time, at home and work hope this helps
I'm not an expert, but doesn't that mean you are stuck in 2G-Mode for Data Transfer? I believe 3G if available would be faster..... or am i wrong?

yeah, it stays in 2g for data but for me its an acceptable trade off to actually be able to recieve calls. plus you can always switch 3g back on if you plan on doing something that uses a lot of data and switch it back off when youre done
damm i was excited until i saw that you have to disable 3G
Is this a common problem?
or... you could just go to settings/wireless&networks/mobile networks and change the network mode to gsm only (which is 2g) so, same thing.. and you know what? i still have signal issues, just not as bad..

yea i think that option is only on Desire or froyo builds, on all of the GB's ive used it says 2G. i suppose its not gonna work for everyone, it probably still depends on your coverage area, but it definately helped me A LOT. ive been using these settings for the past 3 days and my time without signal has dropped down to 0-5% from the 55-75% it was before, and im no longer missing calls
very useful tips
I ticked the "Use 2G only" checkbox in my wireless settings and all connection problems seem to be gone! (for now)... My data connection used to be terrible... voice connection shaky.
Thanks a lot!
I get error 78 when roaming. Cannot get a data connection!!! Help can anyone data roam?
If you are asking if you can use data while your phone is roaming then yes. My phone roams with data 24/7.

where would you be located? maybe the problem is my area?
Depending on your rom, you may have to allow it in settings. I know in my "mobile network settings" on MIUI there's an option to allow or disable data roaming. I'm not sure of the default, but mine is disabled. I don't remember changing it, but I may have.

Go to Menu, settings, Wireless & Networks, Mobile networks, make sure "data roaming" is checked on.
stock rom and yes allow data roaming it enabled.
When i have it roam it grabs data then loses it ending with error 78
happened on unrooted and rooted. two different evos

I had this problem also. You have to call sprint and have them update your profile,and or provisioing(is that a word) on their end. After that all was good, also when you flash a new rom always update your profile, and prl after first boot.

If you are on the west coast, sprint is experiencing 3g outages. I got a different error code, but it's probably related to the same outage as sprint may not be able to authenticate your device on the roaming network.

I have been told by sprint today about the outage
I can currently access 3g on sprints side but nothing on roaming. however my wife with a blackberry style can data roam
Just activated it today, no data in Chicago either.
Just yesterday i installed stock rom froyo for my sister's defy and those 3 options are missing in Mobile Network settings...
The Data enabled, Data roaming and National data roaming options are missing, What to do?

I'm on stock now.
I got charged for using data in roaming even though my Nexus 4 had "Data roaming" set to off.
Allegedly my phone downloaded 18Mb while in roaming.
Has anybody else had this happen to them?
Is there a log on the phone that can confirm the data transfer at particular time of the day?
Thanks!

I have the same problem with my S4.
I got an international version SM-G900i from Amazon. I have an ATT sim card. The text and phone calls work fine but I could not get any data roaming. Though from other posts I got the data roaming, I was not able to set onto the ATT 3G/2G network in the network operator selection. My network is always shown as Maritime. Does anybody know why this happens and ways to change it?
Thanks a lot.

Have you checked apn setting and made sure they are correct for ATT?
Well,,,,

I tried configure the APN setting based on a link online for ATT APN. Now I am losing signals even for calls and texts....I think there might be other things that are wrong...
Error message for no ATT service
Tried different variety of ATT APN setting. Still could not get it to work....the phone shows a signal but gave me an error message that Selected network(AT&T) not available

I'm not sure what did you mean by "data roaming"??
Anyway, the problem for now is no network register. The APN settings will NOT affect at this step, so not not try to mess up with it right now.
Try to get into Settings > More networks > Mobile networks, and set Network mode to Auto connect, and Network operator > Select automatically.
That may help the device to register on the Home network.
Problem solved....or maybe not but it is working!

Okay. Thanks. I switched it back to the auto-selection mode. By data roaming....I mean 3G data. My phone is working now. I checked ATT billing usage report, it did not increase the data usage dramatically so I guess everything is fine.

Glad that your phone works now.
BTW "data roaming" and "3G data" are different things. "data roaming" is "3G data" when you are roaming to another network (not your home network).
