could not activate mobile data network

[Anonymous]

I put my pay monthly 3g sim which has data plan into a iphone 3gs but can only connect to internet via wifi. How do i get it to connect to internet away from my home.

VVM will only work with iData so you will need to call CS (202) and request the data is changed to iData. After 24 hours you need to change the apn back to the original settings (reset should sort this), then unique iPhone features will work.

Another helpful reply - Thank you.

Before I call O2 - does anyone know if I am doing anything wrong by doing this, and will O2 agree to make the change or will they want to change the tariff?

The (broken) Samsung phone was hers - on an O2 tariff (that includes data), the iPhone is my old one (originally on an O2 tariff) now upgraded to an iPhone 5 (on an O2 tariff). I'm not sure I want to pay any more for her to use a 4 year-old phone!

It's free to change and no problem at all.

I cannot activate my mobile data network on iPhone c ??

It usually means your apn is wrong or data is turned off? - Try a network reset first and if not hold power and home button until the apple logo appears on screen.
That should sort it out, if not come back and e'll go through the apn's manually.
