this is the worst ever mobile provider .you call their customer service and they act as if they are doing the customer a favor. They are rude and will tell you to call back whilst your problem is not solved, because they want to pick another customer. they care about the amount of calls they pick rather than the satisfaction of the customer. I wonder if they are trained.
you even ask a simple question and they beat about the bush. i have spoken to about 8 different customer service and they are all extremely rude.(German customer services).will never recommend this provider to any human being.
