I purchased a new Samsung S3 in Victoria BC last week and went on a business trip to Ontario secure in the knowledge I could contact my associates here as required. I bring up the keyboard and type in a number and it immediately shows an orange bar saying "call ended". What am I missig here? There are 4-5 bars on the reception and I am connected to the local hotel internet with no problem for email, but I can't use the phone. Hwlp please!!!!
