Another "Could not activate cellular data network" user !!

I've been a long standing O2 and always wanted an iPhone.  I took the route of buying a PAYG phone from them, and had it unlocked after 6 months (worked out about £5 than buying an unlocked phone from apple, plus the O2's rate including data usage was more appealing for my use), however at work there is no O2 3G signal, but a good Vodafone one


So I have a vodafone PAYG SIM, topped it up with £15, and then used £5 of that to buy the Web package to test things out.  In my account it is definately active and showing lots of red dots (expires Sept 4th), but I still can't use the 3G outdoors (when I go into the settings page, I see Voda with 3 blue bars next to it and 3G in blue).  There is a Voda mast right next to where we work, so it's not a signal problem!


I've upgraded my iphone to iOS 4.3.5


Definately not in airplane mode

Can receive/send phone calls and texts

General -> Network :  Cellular data is ON


Cellular data has the following settings

Cellular Data
username - wap
password - wap

username - wap
password - wap
MMS Proxy -
MMS Max Message Size = 307200
MMS UA Prof URL - blank


Yet I still get "Could not activate cellular data network" .  Swap in my O2 SIM, and go outside, O2 is fine.  I have done this in 2 locations where a Voda USB dongle works fine.  I'm banging my head against a wall as I'd really like to move to Voda, but this is stopping me. Any ideas please?

Hi sweepdog.


Thank you for your post. :smileyhappy:


I understand how frustrating it can be when you are paying for something you are not able to use it.


I would love to help you with this and due to the details you have provided means I am going to need to look into your account to check if any bars are currently on there and get them removed, to do this I have sent an email for you to complete and reply to in order for me to rectify this. 


Hope to hear from you soon.


Many Thanks
