iPhone 3GS - 3G Problems. (O2)

[PaulMacC]

I got my 3GS @ Christmas, working fine ever since but today the 3G says "No Internet Connection" when I try to connect. I've been trying everywhere, the WiFi works perfectly but the 3G doesnt. I'm on PAYG and get free 3G for 1 year, I got my 3GS at Christmas so yeah. Can anyone post their settings for 3G within their iPhone if your on 02?

Using iPhone with an O2 Pay & Go SIM card

Your iPhone is automatically set to Pay Monthly, so once you've activated the iPhone you'll need to change the settings to Pay & Go to get the things like mobile internet to work. Here's how:

* Go to settings menu, choose General
* Choose Network, then Cellular Data Network
* In the cellular data APN box, change idata.o2.co.uk to payandgo.o2.co.uk - you don't need to change the username and password.
* Then, in the MMS APN box, change idata.o2.co.uk to payandgo.o2.co.uk - you don't need to change the username and password.
* Visual voicemail isn't available for Pay & Go customers. You don't need to update the APN in this box.
* When finished, switch your iPhone off and back on again
* Finally top-up by a minimum of £10 if you've not topped up already.
