Hello Pav! We do block the Data once it's reached $50 to avoid going over this cap. Once the $50 is reached, we block the data and send a message to our customers and give them the option to accept the charges if they would like to use more data. The roaming plans that we have to offer are available on our website http://koo.do/Im7Mcg .We currently don't have a $5/day option , but who knows what the future holds :)? There have been a few Ideas posted on our Community by our other members about our roaming plans, and you can go like them! Have a great day!
