When I recently bought a SIM card for the first mobile phone of my 10 year old nephew I was positively surprised that unlike most other prepaid offers I have seen for a long time, packet switched network access is enabled by default but all attempts to browse the web are redirected to a landing page from which a tarrif has to be selected before Internet access is granted and the prepaid account is charged. This is great as even if he should accidentally activate Internet access while browsing through the menu structure and playing with the device it will still be free of charge until an option from the landing page has been selected. No accidental activation and subsequent charing, I hope that is something I will see more often in the future on prepaid offers!
