I appreciate all your responses but dont want to cause any problems.
To be clear i live in NY and I travel to Europe and Argentina, I dont seem to have problems in B's As with Wifi and Broadband connections but in Italy especially I spend time in an area with no hard line phones nor any cable or Wifi, I am trying to use my laptop or if necessary change my mobile phone (Cingular) for a blackberry with internationally service (cingular has it) Cingular is now selling aircards for laptop Sierra 860 and Option gtmax (plus another one) and they say that they are good internationally. I tried calling Cingular but of course the people I speak to do not seem to know anything about them or the service plans and whether there are roaming charges. Or do I have to sign up with vodaphone or timm.

In any event since I am totally confused I appreciate any help...thanks
