HI. My husband and I both purchased the international combo $40 before we left for Paris. Problem is that now that we are in France we can't text or call anyone (not even 611). A message appears saying outbound calls are blocked. I have tried turning off the phone, taking out the battery and SIM card and nothing works. We have a Samsung Galaxy 4. Please help. We would really like to talk to our 3 year old son.
