"Garbage customer service and plan. I purchased a plan with international roaming. Called o2 numerous times and tried to get the data to work and their solution was to use wifi!!! What was the point of me getting the plan if it won't work? They refuse to give me a supervisor to talk to and they said it's part of my contact but won't tell me what they're referring to and blamed the network in Toronto and New York saying it must be down ... I was their for two weeks, doubt it was down that long. Either way 3 and ee were so much better by all means."
