Q: ios 6 no internet on 3G

I would suspect that this is an actual carrier issue because if this affected all iOS6 devices, this thread would be much more popular.  Another option is to select Settings > General > Reset > Reset Network Settings.    This solved one of my 3G issues before with Sprint.

Cheers

It's NOT a Carrier Issue, No one had this problem before the IOS 6 upgrade. I've reset my "Network Settings" and still NO Data on 3G!!

I'm on Straight Talk Not AT&T, So I know its NOT a Carrier Issue with AT&T.

Okay so I've driven around my area this morning and my 3G works everywhere expect the small village where I live. I also had an email from orange saying they are transferring me to EE which is the new 3G network, according to orange. I will ring orange later and let you know what they say

I am from Romania and my carrier is Vodafone.

I have an iphone 4S and I've upgrade this morning to iOS 6 after that ... surprise ... no internet connection !!!

In my opinion is a bug of the iOS 6 !

If you work at Apple I kindly suggest you to tell to your manager about this issue because will affect millions of devices and this means millions of unhappy Apple users !

I've confirmed as well that the Data Roaming toggle only works temporarily for me. Internet over 3G will work for a bit, but then just hang there and timeout. I can then toggle to the next option (OFF or ON) and it magically starts working again, but eventually will just fail again. Very frustrating.

I'm on Verizon. Full signal. I never had issues of data over 3G failing in these coverage areas before the IO 6 upgrade.

How did everyone else do the update? Was it OTA or through iTunes? I did mine through iTunes, and I'm curious if we can figure out if we all did something similar when we upgraded.

Problem solved :-) My 3G is up and running :-)

I found that the iOS6 installment somehow changed the existing Cellular Data Network settings of the APN (the 1st one).

For fixing this issue follow the path:

Settings > General > Cellular > switch Cellular Data from ON to OFF in order to enable the Cellular Data Network > click on Cellular Data Network and here I think that based on the country/ contract/ carrier/ you have 3 options:

1. you know your APN settings and you modify them, turn the Cellular Data back to ON, switch off your and after that switch on phone and it works (my case :-)

2. click on Reset Setting (you have to scroll down), turn the Cellular Data back to ON, switch off and after that switch on your phone and it works

3. you dont know your settings and therefore you call your carrier customer care and they will help you (Vodafone, Orange, ...)

Good luck and if it works please let me know and spread the word,

I had the same issue while in China using China Unicom. I verified it was not a sim issue or carrier issue by switching my sim chip with someone else. Their sim did not work either in my phone. My sim worked in their phone.

Next, I did as Mada1981 recommended and turned off the data then I went to Settings-->General-->Reset. Then I executed the "Reset Network Settings". It rebooted my phone and now 3G works fine.

I now need to go back and register my Wifi networks.

Option 1 worked for me... IOS6 simply deleted all settings (fields were empty). I'm from Serbia, my carrier is MTS.

I haven't had to reset network settings.

Thank you. Your solution works for my Orange UK service and roaming is now working ! GREAT

For those who still hanging on problem.

Access www.unlockit.co.nz from iPhone (over WiFi or E, if its posible).

Then  choose Create APN, and then select your country and operator. It will install a profile on your phone, changing APN settings.

After this, restart phone.

For me this not solved, but make my 3G less flawless.
