Cannot find 'Mobile Data Network' button for iphone 4 using virginmobile.

Hi,
I use an unlocked iPhone 4 with the latest 7.1.2 iOS. (At least the latest you can get for that phone.)
I recently switched from O2 to Virginmobile to get better coverage. (The EE network is so much better.)
However I cannot send MMS and emails (whether I'm connected to WiFi or not). I cannot access internet when I'm not connected to WiFi.
I have called 789 at least twice to get this resolved. Each time they failed because of the missing button: 'Settings/Mobile/Mobile Data Network'.
Cellular Data Network etc is not there either. I cannot find the button anywhere.
Virgin did give me the details of what to enter should I one day find a way. Although I had got this off the internet already. I was calling them because I cannot find that button! They seemed to expect it to be there.
I have tried resetting all settings and also resetting just the network settings.
The button was available when I was using O2. MMS, email, internet all worked fine because I could set it up manually. The button dissappeared when I switched to Virgin.
So my questions:
Should I be able to see this button?
If yes, what has gone wrong?
If no, how can I set the apn etc settings correctly?
Please note that I have contacted Virgin via the community forum and over the phone to no avail. They suggest I talk to Apple to see if they know why the button has disappeared. They suggest it may be because the iphone has been unlocked.
My household has an iphone 3gs, two 4 and one 4S. All seem to be missing the button or equivalent.
Any help gratefully received.
Regards,
Ronnie

What does it say in your "About"? Go to settings>General>About and it should tell you your carrier. If you have carrier service but it does not show, you might want to contact them again. If the carrier name shows, but you do not get service, try Settings>General>Reset>Tap Reset Network Settings. You will need to enter your wifi password back in afterwards.

Since upgrading my iPhone 5 to ios 7, I cannot get the internet, email to work on 3g. I get the message ""could not activate mobile data network. You are not subscribed to a mobile data service". How do I fix it?

I've contacted o2, tried all of their suggested updates and changes, reset my phone 3 times and still no luck.
Any help appreciated.

Hi, l have the same problem, were you able to resolve?

HT201699 I'm using an iPhone 4 which i purchased last month, there seems to be some kind of problem with the mobile data network

Hi,
I bought a new iPhone 4 last month, totally fell in love with it untill there was this problem regarding the apn disappearing. I manually added the apn info and it worked fine for some time but soon after I disabled the mobile data/3g connection and enabled it later I always use to get a msg saying "Could not activate mobile data network" even after it being active( 3g symbol always used to be poped up at the top). Though the apn is filled with a valid data it shows me the same msg over and over again. It some times works on rebooting but the rebooting the handset everytime i want to use the connection sounds very pestering. Please suggest me with somehting to get rid of this problem...

Why does my iphone 4s has mobile data instead of cellular data?

"Mobile data" and "cellular data" are the same thing - just depends what your carrier chooses to call it.

Could not activate mobile data network - iPhone 3GS

Hi, I really need some help please.
Last week I started to get this message everytime I tried to use internet services, email, web or apps. I was on 4.1.2 and the phone was officially unlocked and running a T-Mobile sim with auto-update carrier file installed.
I reset the phone, restored it and never worked, subsequently, I have done this many times, reset network settings, hard reset, soft reset and I eventually upgraded to 4.2.1. This still never solved the issue.
After countless restores and resets and iTunes updating the carrier files, nothing is working. I contacted T-Mobile who said there are no connectivity issues, must be the handset. I then contacted Apple who advised the handset is out of warranty and an 'out of warranty' repair will cost minimum £146.
The phone works fine calling, messages and on Wi-Fi it's only internet services that do not work. Is there anything else I can try or has anybody experienced the same problems?

Thanks for the advice. That was one thing I hadn't tried purely becuase it is such a pain in the ***. I reset the phone and set it up as a new one and bingo, it worked fine. I then went to restor from backup, after which, same issue, Could not activate mobile data network, so another reset and now I'm pretty furious that all my phone contacts, apps and messages have all gone.
Next question would be how to transfer phone contacts from phone to sim. I have lost all new numbers that have gone into the phone for the last year, so if I reset again, restore from backup, transfer numbers to sim, then reset again and set up as new phone I should be able to recover numbers at least.

What's wrong with my mobile data network?

I've had this 2nd hand iPhone 4 for almost 2 months and everything has been working perfectly until today. I was using viber and sending messages to my friends and it suddenly stopped working and i have no idea why, i thought i just lost my 3G for a while so i waited a few hours for it to come back up, this started around 3pm and it's 12am right now and it's still not working... Everything else worked such as skype, twitter and the internet but for some reason i couldnt send and receive messages on viber and imessage. I also didn't get any notifications from ANYTHING during the whole time until i connected to my wi-fi at home which i then got flooded with messages, tweets and etc.
I think that theres something wrong with my mobile data network and i dont really know what it is since everything was working fine this afternoon and it just suddenly stopped? Connecting to Wi-fi makes everything work fine and i actually receive notifications and am able to send and receive messages to my friends on viber and imessage.
Can anyone help me?
My carrier is CSL and it has unlimited data if anyone n

I havent contacted my carrier and i really dont think they will be able to help since i go to them every month to pay my phone bill and they can barely speak english...
I've turned my phone on and off 3 times and ive also reseted my network settings

TS4148 I need to change the mobile data network from Vodafone to orange I need the passwords and address to do it my self

I'm trying to find out the mobile data network info on my iPhone 3GS it's on Vodafone at the moment but I want to use my orange sim so I need to change the pan details help

Assumption ...you are in UK
If you purchased the iPhone from Vodafone it will be locked to them
You will need to request they unlock the iPhone before you can use
it on Orange no other way
In UK Apple are the ONLY source of unlocked new iPhones

I bought an unlocked 3G and when I try to use the internet, it says 'Could not activate mobile data network'.

Hi all,
I have recently acquired an iPhone 3G 16GB. It is unlocked and I have put my sim card in (Virgin Mobile) and used it without problem when calling or sending text messages. The internet all works fine when connected to a wi-fi network.
In the top left hand corner it says '3G', however if I try anything related to the internet (Safari, Twitter etc.) a message will appear reading 'Could not activate mobile data network'. This is very inconvenient for me. All internet related activities work fine when connected to a wi-fi network.
Is this a problem with all unlocked phones? Is there a solution to this? Or am I simply unable to use the internet without wi-fi on this model?
Any help would be greatly appreciated, all questions may sound silly, but this is my first iPhone and I am very inexperienced with them!
Thanks

First, you don't have a 3G if you have iOS 6.1.4. The 3G cannot go higher than iOS 4.2.1. That is not related to your problem, but worth knowing.
Let's try the obvious first. Tap the Settings icon. Then tap General. Then Cellular. Is Cellular Data on? Is there an entry for APN? If there is contact your carrier and ask what the APN settings should be. If there is no entry don't worry; the APN is automatic with your carrier.

I'm sorry, but you are going to have to try a little better to explain your issue and what your question is, or post in your native language.

Further, if you are not in your home cellular carrier's area, you need to set Settings > General > Cellular > Data Roaming = "On".

Mobile data network setting

The settings for the mobile data network (APN, User Name, MMS etc.) disappear from time to time for unknown reason.
What can I do to prevent this?

Hello Lil Bizz,
Welcome to the Apple Support Communities!
I understand how frustrating it can be when Wi-Fi on your iPhone is not working as you would expect. In this situation, I would recommend the steps in the attached article to help troubleshoot this situation.

My iPhone 3GS won't let me use my mobile data network since the 5.01 update, does anyone know how to rectify this yet??

Is there a new update from 5.01 that fixes the data network problems yet??

Straight after upgrading mine to 5.1 this morning, I got a very long SMS from O2 telling me how I can connect to the Internet and check all my settings.
Maybe worth checking all of yours are still correct. Maybe they know it can cause a problem
