They had to get an north american plan for it to even work it appears. What a ripoff to start with. You should see this is not too good
The difference between the US and NA plans is you add $49 for whooping 100MB of Canadian/Mexican data!
Dupe the camera card or burn a CD and send it home overnight would be cheaper
On the other hand if you call, they probably say you need the 5GB North American plan without mentioning those 5GB are still US. Knowing at&t i'll bet on this tho.
That $20,000 bill probably cost at&t $100...They will ask for $2000 and settle at $200, the poor little company ... They don't really care if someone can afford that, I bet they make 50% or more after settling. The few people that pay thousands make it all worthwhile
