What is Data Roaming

What is Data Roaming, do i need to leave it on when im in my home network area or does it not matter if it is on/off?

Data Roaming applies when roaming internationally/out of the country on an AT&T partner network.
Roaming internationally must be requested by you and approved by AT&T before doing so. This is beneficial to those who want to minimize their data roaming charges when out of the country since this is billed in full for all data downloaded and uploaded when checking and downloading email and web browsing, etc. There are no such charges when connected via Wi-Fi when roaming internationally - only when using the cellular network for data access.
Also for those who are in the country but live near the border of Mexico or Canada where cellular towers located across the border can be picked up without your knowledge.
It is off by default and you should leave it off unless you travel outside the country and need internet access other than via Wi-Fi.
Scratch the AT&T and U.S. reference - I now see you are located in Scotland but the same applies when what is considered roaming internationally on an O2 partner network.

What is data roaming? Does it cost extra?
Why doesn't my iPhone automatically connect to AT&T service? Sometimes I have to go directly to Carriers in the Settings to connect to AT&T 3G. Thank you in advance.

There is no local data roaming or call roaming in the U.S. as a subscriber with AT&T. Wherever AT&T has coverage in the U.S. is included.
AT&T does not own all the towers in the areas where they have coverage in the U.S. AT&T calls this "off net usage"
The following was copied from AT&T's wireless service agreement.
+If your minutes of use (including unlimited services) on other carrier networks ("off-net usage") during any two consecutive months exceed your off-net usage allowance, AT&T may, at its option terminate your service, deny your continued use of other carriers' coverage or change your plan to one imposing usage charges for off-net usage. Your off-net usage allowance is equal to the lesser of 750 minutes or 40% of the Anytime Minutes included with your plan. AT&T will provide notice that it intends to take any of the above actions, and you may terminate the agreement.+

What is Data Roaming USA

What is Data Roaming USA

Rodlburr,
Happy to answer that for you. Roaming is the general term for anytime your mobile device is communicating with a network other than Verizon Wireless. Data refers to the data signal that is used to transmit data such as email and web. USA refers to roaming inside the United States as opposed to Global which is billed differently. "Data Roaming USA" is domestic communication with a data network other than VZW. Most calling plans include it.
I might be able to provide further insight if you could tell us why you are asking. Is this a feature you see on your line, something listed on your bill or something you see on the phone?

How can I keep data costs low? And what is Data Roaming?

Having trouble staying within data limits and having to pay a fee any suggestions for how to avoid this??? Also, does Data Roaming affect anything?

Well data roaming can seriously affect your bank balance! It is what you use when wanting to use data services abroad and can be very, VERY expensive, depending on where you're from and where you are. Best to keep it switched off when abroad apart from when you definitely want to use it, and use wi-fi as much as possible.
If you are generally struggling to say within your data limit, then maybe it is not enough - how much is it? Avoid downloading music, podcasts, apps and app updates on cellular data - stick to wi-fi for that. But it may be that you need to up the data amount in your plan, and altering the plan may be cheaper than paying every month to top up.

IPhone, VPN and 'data roaming' (UK)

I had great difficulty setting up a VPN link to my university server. Even with identical settings to those on my laptop(s) the iPhone persistently produced the immediate message 'the server does not exist' (Oh! yes it does!). This applied on the EDGE, and more than one WiFi network. (And of course I checked the name very carefully!)
Anyone else with similar problems might like to know that I have solved this, for reasons I am unclear about, by:-
1 - substituting the (hopefully static) numeric IP address for the VPN server name
2 - turning 'on' Data Roaming (default being off)
Neither of these two measures works on their own but the combination works fine. Whilst the first might be easily explained by some DNS issue I do not see why the second measure is necessary, and there are dark warnings about charges in the handbook. What is 'data roaming' and why should it make a difference even when logged into the phone's home network?
Comments appreciated!

When you are outside the normal O2-UK coverage zone (i.e., in another country), then the phone is "Roaming". The Data Roaming switch can be used to control whether the iPhone tried to make a GPRS/EDGE data connection when the phone is roaming. I.e., when your phone is connected to a non-02 network.
If you are in the UK and connected to 02 while trying to connect to your VPN server, then you should not need to turn Data Roaming on. However, if you are trying to connect to your VPN server whilst outside the UK, then I would expect you to need to turn on Data Roaming (unless you are using WiFi)
Hope that clear things up.

Roaming on other carrier's data networks.

Leaving data roaming ON while abroad: what apps use data in the background?

As a quick preface, I've had an iPhone since Week 1 in the summer of 2007. I've been working outside the U.S. for well over a year now, so I've been roaming with my iPhone for almost the entire time I've owned it. I had kept data roaming turned OFF since the fall of '07, when a software update brought it as an option, but visual voicemail continued to work as always even when data roaming was OFF (under software versions 1.x).
After hearing about the early bugs with iPhone software v2.0, I stuck with the last version of 1.x until about a month ago. While I like almost everything about 2.2, I was dismayed to notice that visual voicemail no longer worked if data roaming was turned OFF. (Apparently, the visual voicemail "loophole," for lack of a better phrase, was closed with 2.0 or a subsequent version of the software.)
This has left me facing a conundrum: Turning data roaming ON might leave me susceptible to a big data roaming bill, while leaving it OFF leaves me in the dark as far as the existence and Caller ID of new voicemail(s).
QUESTION: Does anyone know of the DEFINITIVE list of which iPhone apps use data roaming in the background? That is, if I leave data roaming ON but NEVER use the email app or Safari or YouTube or any other app that accesses the internet and would incur data charges (or, at least, never use any of those apps unless connected to a WiFi network), which apps will use data in the background anyway, WITHOUT me actually launching the app?
Back in the 1.x versions, I'm not aware of any apps that used data unless the user actually launched an app, but I've noticed that, under 2.2, Apple's App Store app routinely connects to the internet on its own to check for updates if I have data roaming enabled. (I'd like to turn this OFF, but doing so doesn't appear to be an option.)
I'm hoping App Store is the only app that has this (bad) behavior, and that I'd be safe leaving data roaming ON while consciously avoiding using data over the EDGE network, but I have no idea if apps like Stocks, YouTube, Weather, etc., have been updated, in 2.x or even 2.2, to check for updates in the background, and thus run up data roaming charges.
If anyone can shed any light on this, it would be much appreciated. Thanks very much.

The iPhone is officially unlocked and can be used with whatever provider/SIM card.
But imagine, we are a team of around 20 people, travelling to all kind of different countries all over the world (changing, not the same person is always travelling to the same countries), and of course (I didn't mention this in my first post), we also have to stay in contact by phone. In addition, also whatsapp is based on the phone number as far as I know, which is our main "quick" communication tool. It would never work out that all of us inform the others all the time about the changing phone numbers, depending on which country each individual is at the moment.
Your answer unfortunately just confirmed what my researches so far resulted in... there really seems to be no apple-like easy solution to manage data roaming for apps individually. In the beginning I was sure to quickly find something in the appstore, since I assume my situation is not such an exception. I guess I have to start learning how to program apps! :-)
Anyway, thanks for your answer! As I mentioned before, every idea is appreciated.

I am heading to Mexico for a quick business trip, I only want to receive texts and make a call or two. What do I need to turn off to avoid ANY additional charges? Cellular Data/Data Roaming/MMS/visual voicemail? And should I turn wifi on and leave it on?

Global data charges with data roaming OFF

I have an issue with both my iPhone 4 and 4S getting incoming global data "leakage" I will call it.
Both are running iOS 6.1.3, which is the latest software update. Both phones are used fairly regulary along the San Diego border with Mexico, and often times on the Mexican side within 2-3 miles of the border. My phones are always set as follows: "Cellular Data -> On" Roaming = "Voice Roaming -> On" and "Data Roaming -> Off" with the iPhone 4S also having "International CDMA -> On"
However, both phones consistently receive incoming global data hits in very minor amounts (0.1 KB to 5.5. KB) when they are in an area where the signal is switching between my USA carrier (Verizon) and the Mexican cellphone towers. I know this because almost every time it happens it is when we are crossing the border or close to the border where the towers are competing for the signal to my phones. In one case I watched as my iPhone 4 switched from Verizon 3G to Extended network and shortly thereafter I received a push notification (message) from my WhatsApp application. The next day it showed the hit on my daily usage as a 6.9 KB hit even though data roaming was set to OFF.
Please don't respond to tell me that the solution is to switch Cellular Data -> Off when I am near the border. I already know this will solve the problem, but the issue is that we want to use the full functionality of our phones in this area as our employment and our residence is right along the border and we don't want to have to suspend data completely every single time we cross the border, which is nearly every day.
The data hits have thus far been in the range of less than 500 KB per month total (almost no impact at $5 per MB) so my concern is not so much with the minimal expenses incurred, it is more the principal of the issue and the problem.
I want to know if there are other users experiencing the same issue so I can have some more evidence to get Verizon to push Apple for a fix. Apple iPhones have consistently had "Data/WiFi/Roaming" issues on its phones since 2008 (or more as far as I can tell) and I believe this is a related issue that has never fully been fixed.
Thanks in advance for your replies of similar situations, regardless of what country this happened in.

Thanks for clarifying. I do hope you had a wonderful trip! You mentioned you were turning the cellular data on occasionally to use a little data. When your data is turned on, even for just a few minutes, your phone sees that connection as a window to look through your applications for any notifications that you've missed and download email and other messages, occasionally resulting in a significant amount of data usage. What were the countries that you visited? When you log in to view your statement on http://bit.ly/xB4iTc, does it show you had a $25 Global Data or $29.99 Global Value plan for any part of your trip?
Thank you

AT&T service iPhone International Data Roaming - excessive fees

For info:
I mailed below message to AT&T Customer care: [email protected]
Am sure for many international travelers this will be a nice customer service improvement.
Send them a mail as well. It may help all of us traveling overseas.
"I do have following concerns on AT&T's iPhone International Data roaming service.
I voiced them as well to your service center reps.
The feature is a nice useful service.
But I encountered a number of flaws:
- Long time for service calls.
- Misrepresentation of costs (overcharge of 150%), and
- Resulting in excessive costs.
I am fully aware of all stories on international calls/data roaming with iPhone (ref suggestions on AT&T FAQ)
No need to fill me in on that.
Here is what happened:
- before a month of overseas travel (mid Dec - mid Jan), I had the service activated:
it took me 1/2 hr waiting at the phone before I got to speak a AT&T service rep.
- I was told the service will be charged pro rata (ie days of usage) and for a month travel that would be 25 USD.
and I had to call back upon return to disactivate/cancel service.
- Upon return I called back AT&T service center , again a long on hold waiting time,
and I was told I needed to wait for my next invoice statement to see the my completed overseas period on the bill, and could only cancel the service then.
- This week I received this next statement, called back AT&T service center , again a long on hold waiting time,
and now I was told the service would be cancelled only as from this very day, and no retroactive cancellation.
I was told the reason is to allow bills from overseas carriers to be taken into account for the invoicing and the international feature.
In other words, if I had cancelled immediately upon return, overseas charges booked into my bill after my cancellation call (but incurred before) would be hitting me at full charge.
Thanks for doing so, but all this results in a 2.5 months service period for this feature, while I had only wished a 1 month service period and was told I would incur only a 1 month service charge !
A number of suggestions,
- make the feature true pro rata charges, now it is a misrepresentation and an excessive overcharge.
- AT&T has a nice individual account profile online, why can one not activate/disactivate the service there ? Will be much faster.
- or have the service activated with a separate credit card purchase/billing ?
Hey, and advertise it on iPhone/Apple.
Loads of people who are traveling overseas will be interested ! "
Cheers
Tom

DexGtr,
If you go to Settings -> Network, there is an option to turn off data roaming.
However, if she hasn't updated her firmware since she purchased it that option may not be available.
iPhone Firmware updates are downloaded via iTunes. Connected the iPhone to iTunes, and if it doesn't prompt you to update, then click on "Check for Updates" in the iPhone Summary tab.
Hope this helps,
Nathan C.

GPS does not appear to work with data-roaming off and no wi-fi network

I have been using an application called imarkmyspot to produce way-points for synchronising with my camera. When I am in my home country this works fine and a GPS location is found quickly.
I've recently been abroad and had data-roaming turned off to avoid high expense. The point is that in this situation the GPS does not work (with imarkmyspot or Goggle Maps) unless I can access an open wi-fi network.
So my question is, is this correct? Does GPS only work with either data access on or when within range of an open wi-fi network.
If this is feature (bug) of the iPhone then this makes applications such as imarkmyspot rather useless when travelling. Alternatively it could be imarkmyspot that has this problem of course. But I'm quite sure Google Maps did not work either in this situation either.

The iPhone's GPS does work without a data connection.
Two weeks ago on a work-related trip I knew I'd be traveling a rural highway that would leave me without data/voice from any source for at least 45 minutes (no GSM service). Before leaving a city with data, I zoomed out using Google Maps far enough to show most of my route, then "nudged" the map so the application wouldn't try to get a data update for the map. I simply used the top power button to turn on and off the screen. The iPhone and GMaps tracked me through for the entire blacked-out section of my trip - I made sure the device had a decent view of the sky and it got a fix and nailed the location within a few seconds.
Ironically, I'm returning that device in the next few hours for an exchange. The GPS hardware, it seems, has failed about a week ago - the device gets A-GPS fixes now (it shows the nearby 3G and EDGE towers), but won't lock in for more than a second or two. My iPhone's GPS worked, and now it doesn't - AppleCare told me my GPS hardware has failed - and you're may be exhibiting the same failure.
Some A-GPS devices use their sources to get close by - like my TomTom GO and the ephemeris files it grabs from their servers to get updates on where satellite locations are - and then use the on-board chip to nail the device's position. From what I understand of the iPhone's assistance mechanism, the data tower's and Wi-Fi physical location needs to be correct and available in an accessible database somewhere - my iPhone was showing me near Houston TX (2200 mi/3500 km distant from my actual location) when using 3G data until the data source was updated.

Skype Abroad - No Wifi and No Data Roaming

I will be going on a trip to Turkey in a few weeks, and I am trying to understand if I can make calls with the Skype app on my Droid without a wifi connection and with data roaming turned off. I thought I read somewhere that Skype has it's own 3G network or some other method that I can use to make calls with the Skype app. I would be buying Skype credit in advance. Is what I am saying possible?
My goal is to be able to use Skype to make phone calls without wifi and without getting charged for data roaming by cell phone carrier. Thank you for your help.

Sure, I know about SGO.
The poster was asking how he can use Skype app abroad, without roaming charges, without any internet connection. This is not possible, unfortunately.
If we are talking about SGO usage in Turkey, this won't work either, as there are no local SGO numbers there.

Data Roaming in Japan with the Android Bionic - or not...

I signed up for a global data plan using my Android Bionic. I can receive calls without a problem and I'm able to place calls. However despite my best efforts I am unable to use any data on my phone (every time I try I get the message "No Data Connection" . I have enabled data roaming and checked all of the settings I can find. Anybody care/able to tell me what I'm doing wrong? It's a major inconvenience to not have data access while here. FWIW, I'm in Kobe, which according to the map should have full voice and CDMA data coverage.

Hey everyone,
So I just called the verizon customer service whom connected me to global data customer service (or whatever the name was...)
Basically most cities in Japan doesn't support CDMA network, which is required for Bionic (and I'm assuming for Nexus as well) for data roaming. Most of Japan's network is using GSM. I believe some Verizon android phones supports GSM, though not sure which ones they are.
I asked her when I signed up for the global service plan, why the customer rep didn't check my phone's incompatibility for Tokyo. She said that the customer service will usually only check at the country level, and not by cities. On their system, Japan is shown as eligible as some cities does support CDMA.
I also asked which cities support CDMA network, and she said Sendai, Yokohayam, Osaka, Toyama. Probably there's few others but that was enough as a list for me.
David, I didn't check if Kobe has CDMA coverage (as you stated), so for your case, I'm not sure if my issue applies.
Btw, I stopped my global data service plan immediately, as there's no use. However the lady that helped me out was very helpful in detail so kudos to her!

Data roaming won't work in Ireland

Hi,
I visited Dublin last weekend (cheers!) and took my iPhone with me (coming from Switzerland). There was no data roaming all the time, even though I had it activated in my settings. The E logo just did not show up, and data connections were refused with an error message.
I figured out the EDGE settings for the different irish carriers and entered them - no change (ok, now I read you have to use your home carrier's settings, so this was futile anyway).
Any idea what could have gone wrong?
A.
PS. Yeah, I know it's expensive... but looking up streets would still have been valuable.

My carrier is T-Mobile (the same as in Germany). The handbook told me to get my carrier to enable roaming, but I was informed thas roaming (speech and data) is generally enabled, I didn't have to do anything. I am aware, that I can switch off data roaming.
Thank You!
I am still looking forward to my holydays in Ireland.
Bye beye,
Roland

HT1807 I have an iPhone 3s. How do I turn OFF data roaming?

I am traveling in Mexico. I have an iPhone 3s. How do I turn OFF data roaming? Under SETTINGS I don't see Network. I don'r see it under SETTINGS/General either.

What you should do, if you don't want any nasty surprises, is put your phone in Airplane mode. That turns off all iPhone radios, but you can go back into settings & turn WiFi back on.
Do not rely on the data roaming setting to protect you.
