I bought Three 10GB data only package a few times. Last month I used all 10GB in roaming mode. This month with a new package of 10GB data, when reaching 2GB in roaming mode, my data use was cut off. Rather than reference to the 12GB monthly data limit as advertised in their website and in my personal Three area, they now refer to an unclear document under their priceguide, which document I don't know. They set a data limit of 12GB per year or per rolling two months (still not clear) rather than per month. Anyway Three lost a customer today. They offered me to buy add-on data but I don't want to do business with a company which is not transparant about their pricing structure and data roaming policy. Byebye Three.
