I cant use the 3G internet on my Iphone?

[princeasia123]

I just bought my iphone yesterday which is locked on 02, and also i got a brand new SIM CARD for 02 which with a £15 topup i get Free browsing.

I can use Wi-Fi Internet, but when i try to use 3G internet, i get an error message saying 'Could not activate cellular data network. You are not suscribed to a cellular data service'

I got this Free internet SIM so i could use my internet whilst roaming

How cna i solve this?
SugarBear - but how do i do that? got any instructions anyone?

You answered your own question. You are not subscribed to a cellular data service. You have to activate a data service package.

I think you will need to topup first or call 4444
