More than one have a Blackberry and want to connect to the Internet via wifi without being charged anything.
The forums are many who complain that even with Wifi enabled phone company charges them every time they connect to the Internet or chat.
1 In the menu: Manage Connections / Mobile Network Options / Data Service / sure to select Disable . But watch out! there are people that if you do not go the wifi internet, or in the case of RIEF, later or try to connect to another network lets go suddenly the Internet than before YES I was going:
"Can not connect to the internet. Try again later.
Contact your service provider if the problem persists."
That making a wifi network diagnostics says "ip address is not Valda", where is your case, leave it enabled.
2 º And most important ( and really the only thing to do) , to ensure that under no circumstance you will charge for connecting to the Internet, call your company (22,155 in the case of Vodafone , with a total cost of 0.59 € per call) and say you want me to turn off data service and not under any circumstances want you can charge for connecting to the Internet (and if they do have an obligation to return the money.) So you can leave as quietly enabled data service and avoid any shocks and headaches later.
Easy is not it? but before vodafone calling 123, what you off, but now you have to go to the "Service" (that you read what it says on your screen in 99% of cases even without meaning what you say) as its so.
