Viigo can use TCP settings and do not require a BB data plan, however you will need data transfer active on your plan, (this is default on in Norway atleast)
The options are acessible trough Options -> Advanced -> TCP.
But you need to fill inn your correct carrier specific settings, or else you run the risk of beeing overcharged.
You should contact your carrier and ask for the correct settings and if your plan allows data traffic, note that you will be charged for that traffic.
JSanders is correct, it don't seems like you use it as a PDA only ;p
