Failing data roaming with iPhone

I have a iPhone bought in Belgium (bought legally unbundled from operator) and I am using it now in China with a China Mobile SIM card. I have a normal voice & data package which allows me to access my mails and the internet using my Nokia phone.
When using the iPhone, it constantly claims: "Could not activate cellular data network. You are not subscribed to a cellular data service" which is not true as I can easily access with the same SIM card the data services with another phone.
Any suggestions?

Hi,
what do you mean by connection settings?
there is a window called "Cellular Data Network" with APN, Username and Password but I do not have such info and it is not needed for any other phone I have been using in the last many years to get data.

Erroneous data roaming on iPhone 6

I've had a couple of instances where small amounts of roaming data usage on non consecutive days are reported by my carrier (Rogers) after travelling abroad in Europe. The phone is an iPhone 6 running IOS 8.2 ((12D508) and both Data Roaming and Cellular Data were turned off. The phone also says in Settings that "0" bytes were used while roaming. The data usage is very small. 29 kb on one day and 285 kb on another.
Does anyone have any ideas on what could be going on. The carrier has kindly reversed the charges incurred but is unable to explain other than suggest I might have turned roaming on briefly which I know I didn't.

Queen_TheHeard,
You asked:
"Are there settings on the iphone 6 that could assist with data consumption?"
If you go to Settings...Cellular, and scroll down the page, you will see a list of all your apps. The ones that have used cell data indicate how much they have used (74.2 KB, 1.5 MB, etc). You can turn off cell data for any apps you want to use only with wifi.
System Services, near the bottom of the list, will tell you what iphone processes (other than apps) used data.
At the bottom of the screen is a Reset Statistics option. You can reset this at any time to track data usage from that point on.
You may also want to log into your Verizon account online and see list of when and how much data was used. This might tell you how/when your high amounts of data were used.
Hope this helps!

How to disable data roaming with Nokia 97mini

Hello one and all,
Is it possible to disable data roaming on Nokia 97mini? I would like to be able to go abroad and have it automatically stop syncing my email etc... but still be able to use it for SMS and voice calls. I know that the iPhone has the ability to turn off data transfers when roaming on another network.
Can other so called 'smart' phones such as the Nokia 97 mini also do this?
I have searched in vain in the supplied user manual.
All help greatly appreciated.
T

I don't believe there's such an option, sorry. S60's got plenty of options for managing call roaming but as far as I know data roaming hasn't come up.
Help I'm trapped in a sig factory.

Data security with iPhone sync to First Class over Rogers network

I manage about 20 iPhones over the Rogers network in Southern Ontario. We use them to sync Contact and Calendar info to our First Class email system and to collect email via an IMAP connection to First Class. I've got some users concerned about data security when they sync their calendars and contacts and about the vulnerability of their email. Most of these concerns come from former BlackBerry users who felt their data was encrypted with a BlackBerry and now isn't with the iPhone. Oh ya, I've set up the calendar and contact sync by using instructions my Apple rep gave me. Basically you set up an Exchange account and leave out the domain name and the iPhone syncs with First Class perfectly.
Any thoughts?
Thanks

The iPhone's Mail client supports SSL for the incoming and outgoing mail server, but supporting a connection using SSL depends on the email account provider. If you control this, enable connecting to the incoming and outgoing mail server via SSL and require doing so when accessing the account with the iPhone's Mail client.
I don't know what security is included when connecting to an Exchange server via ActiveSync for over the air syncing for contact info and calendar events, but since this is used by businesses, the connection should be secure.

Satellite Pro A200 failing to connect with iphone hotspot via wifi

Apologies if I get some of the technical jargon wrong but I pretty useless when it comes to IT issues.
I have a Satellite Pro A200 and had problems connecting to various wifi connections.
The computer would see the wifi connection and connect to it but i wasn't able to connect to the internet.
The office issue has now been sorted by our IT support guy (security settings on the new router we too complex for my PC or something like that) but he wasn't able to solve the problem of not being able to connect to my iphone to use the 'hotspot' feature via wifi.
Does anyone know a way of solving this or is it a simple fact of the laptop being too old and really needs updating?
Thanks for any assistance anyone is able to give.

> Does anyone know a way of solving this or is it a simple fact of the laptop being too old and really needs updating?
This is not a question of notebook age
As far as I know not all mobile phone providers support this
You should firstly ask your mobile provider if you can use the tethering function.
If this would be supported my mobile provider, then you have to connect the iphone to the notebook firstly
For that youve got two options: you could use the BT connection (in such case check if notebook supports BT too) or via USB cable provided with the iPhone.
(PS: As far as I know tethering is support by iOS3.0 and higher)
After the iphone has been connected to the notebook you need to enable the tethering on iphone.
Under Settings -> Network you should see the option internet tethering this need to be enabled.
Now you should be able to see that in Network & sharing Center of the control panel.

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.

Anyone noted Bluetooth connection issues with iPhone 4s and Ford sync?

My wifes iPhone 4 with IOS 5.0.1 auto connects to Ford Sync at least 75% of the time on first attempt. My new iPhone 4S with IOS 5.0.1 takes 4-5 attempts and rarely if ever connects without multiple attempts. Any one else seeing issues with failed Bluetooth connections with iPhone 4S phones?

Look at the right panel for links to other threads concerning problems with Fords. And it's not just Fords, cars in general. No solutions seem to be given.

IPhone 4 with iOS 5.0.1 - Data Roaming Off/On control missing

My iPhone 4 with iOS 5.0.1 does not have the Data Roaming Off/On control under Settings>General>Network. Where did this critical control go? It is still referenced in the iPhone user Manual for iOS 5. Note that this is very different from the Cellular Data Off/On control. The Data Roaming control should be default Off to prevent using very expensive data when roaming outside the USA.

Do a reset (Hold Sleep/Wake and Home buttons about 10 secs or more till Apple logo appears)
Is your iPhone belongs to your company?

Face time with wifi only. I have a 4Gs iPhone traveling to Japan. Can I use face time with another 4Gs or IMacback in the States using just wifi and with I have my Celluar Data and Data Roaming off?

Face time with wifi only. I have a 4Gs iPhone traveling to Japan. Can I use face time with another 4Gs or IMacback in the States using just wifi and with I have my Celluar Data and Data Roaming off?

Thanks, After changing my settings in face time per your suggestion, (it needed to be done), I turned off cellular data and data roaming and made a call using face time. It worked! Great way to stay in touch while overseas without the need for those egregious phone data plans.

With two iPhones 4, turning on Facetime on both iPhones, turning on Data Roaming, Enable 3G, cellular data. Wifi has been enabled on, Wi-Fi is on, 'ask to join networks' is on. I cannot get the two iPhones 4 to do 'FaceTime' with each other. Changes?

May 16, 2011: The two iPhone 4 phones, being next to each other, cannot do FaceTime. with Data Roaming = On, Wi-Fi = On, 'Ask to join Networks' = On, Enable 3G = On, Cellular Data = On,
Why is Facetime on one iPhone 4 not connecting to ther other iPhone 4 when both have the 'FaceTime' icon showing on both?

I will through that note and have applied the items in that note on both iPhones. Both iPhones are in the same physical location. Both appear to be connected to a wi-fi network. Still no FaceTime connection. Is it such that both iPhones must be connected to a Wi-Fi and that wifi must be a network without a password needed to join it? I thought 'Data Roaming = On' was such that iPhone 4 would then find a wifi network without a password needed and one could use FaceTime.
Is that the incorrect assumption? If yes or no, what specific items are needed to be checked before I do this again or be checked while attempting FaceTime.

Getting data off an iPhone 4 with failed backup?

I have an iPhone 4 which I tried upgrading to 6.1.3 while it was NOT CONNECTED TO A COMPUTER. The upgrade failed, and my phone gives the USB to iTunes icon. When I plug it in to a computer now, iTunes says it is in recover mode and I must restore it before I can use it with iTunes.
This iPhone was only ever backed-up on a computer that was lost, so there isn't any record of any of it's data on any other machine. Since I wasn't connected to iTunes when attempting to upgrade, it wouldn't have created any backup during upgrade on a computer. The phone has lot of pictures of my kids on it that I would really love to get, but I don't know if there is any way to access the data from the phone. I'm hesitant to perform any restore with iTunes because I expect it will overwrite the data.
Are there any programs that I can use to recover data DIRECTLY FROM THE PHONE, or forensic specialists who mught be able to access it? Or do I need to just accept the loss and move on?
Peter
I already tried:
Plugging into a PC (it said device driver failed to install properly)
PLugging into a Mac with iTunes and iExplore (says the phone needs to be restored before it can be used with iTunes)

There are a number of commercial products on the market that "claim" to be able to recover data from an iPhone. You can Google them yourself...they all run about US $100 & whether any work or not, I can't say. These folks know what they're doing, but they are not cheap:
http://www.drivesaversdatarecovery.com/
If using a PC, have you tried to see if Windows Explorer sees the pics in your camera roll or the Camera/Scanner wizard? Even in recovery mode, they might be able to see the pics...they see the phone as a digital camera.

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.

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

I have a production mobile Flex app that uses RemoteObject calls for all data access, and it's working well, except for a new remote call I just added that only fails when running with a release build. The same call works fine when running on the device

I have a production mobile Flex app that uses RemoteObject calls for all data access, and it's working well, except for a new remote call I just added that only fails when running with a release build. The same call works fine when running on the device (iPhone) using debug build. When running with a release build, the result handler is never called (nor is the fault handler called). Viewing the BlazeDS logs in debug mode, the call is received and send back with data. I've narrowed it down to what seems to be a data size issue.
I have targeted one specific data call that returns in the String value a string length of 44kb, which fails in the release build (result or fault handler never called), but the result handler is called as expected in debug build. When I do not populate the String value (in server side Java code) on the object (just set it empty string), the result handler is then called, and the object is returned (release build).
The custom object being returned in the call is a very a simple object, with getters/setters for simple types boolean, int, String, and one org.23c.dom.Document type. This same object type is used on other other RemoteObject calls (different data) and works fine (release and debug builds). I originally was returning as a Document, but, just to make sure this wasn't the problem, changed the value to be returned to a String, just to rule out XML/Dom issues in serialization.
I don't understand 1) why the release build vs. debug build behavior is different for a RemoteObject call, 2) why the calls work in debug build when sending over a somewhat large (but, not unreasonable) amount of data in a String object, but not in release build.
I have't tried to find out exactly where the failure point in size is, but, not sure that's even relevant, since 44kb isn't an unreasonable size to expect.
By turning on the Debug mode in BlazeDS, I can see the object and it's attributes being serialized and everything looks good there. The calls are received and processed appropriately in BlazeDS for both debug and release build testing.
Anyone have an idea on other things to try to debug/resolve this?
Platform testing is BlazeDS 4, Flashbuilder 4.7, Websphere 8 server, iPhone (iOS 7.1.2). Tried using multiple Flex SDK's 4.12 to the latest 4.13, with no change in behavior.
Thanks!

After a week's worth of debugging, I found the issue.
The Java type returned from the call was defined as ArrayList. Changing it to List resolved the problem.
I'm not sure why ArrayList isn't a valid return type, I've been looking at the Adobe docs, and still can't see why this isn't valid. And, why it works in Debug mode and not in Release build is even stranger. Maybe someone can shed some light on the logic here to me.
