I am Canadian and am in the States until Saturday, I signed up through text for U.S. Data with Unlimited Minutes & Text 3 days $30 Unlimited minutes 150 MB of data Unlimited outgoing texts Free incoming texts but I have NEVER done this before and my phone keeps telling me: "Data roaming: you have lost connectivity because you left your home network with data roaming turned off." But when I go into the data roaming section, it warns me if I turn on data roaming, "using mobile data while roaming may result in additional charges". YIKES!! Please help? I am sure it's a simple answer but compltetely foreign to any of this, what's the right answer so I am not paying for extra?! Turning on the roaming, or leave it off?!?! HELP!
