Yallo Sanctions must be imposed against this fraudulent provider

They offer you a cheap contract but your first invoice will be a nightmare. Roaming and extra cost ended for me in total cost from more than 230chf. There is no provider in the whole world that calculate these crazy prices.honest providers will block roaming after you passed the border. Yallo is cheap in there offers but very expensive in the end. My suggestion is that the law must protect us against these kind of money-makers.
