I pay around 19EUR but get only 5GB data, and I'm fine with that. When in CH I buy an extra bundle, but even then the costs stay very far below a crazy 70EUR. D

I pay around 19EUR but get only 5GB data, and I'm fine with that. When in CH I buy an extra bundle, but even then the costs stay very far below a crazy 70EUR. Data is blocked when I haven't paid for roaming, so no risk there.
