Help with Orange Tarrif.

[Datamonkey]

Hey up guys,

I have a k800i with orange at the moment,

Im a heavy texter, but i am also using my phone with my tomtom 510 for traffic routing.

Now this i understand uses the 3g side of things for downloading the traffic data,

What tarrif should i go on? Also anyone know how much its likely to download data size wise?

Just dont want to pay £50 to tomtom for the yearly use, and then find its costing me £50 a month on data costs from orange lol

I have set it up to update every 30mins en-route.

Any advice/help any other users?

Cheers
