Especially with mobile roaming data traffic in Zone RoW, the costs can rise quickly. As a prevention mechanism each SIM card has a Warning Profile related to the Data Usage, which is known as “Bill Shock Prevention”. The Data service is suspended when the Bill Shock limit is reached during the calendar month. This will be followed by a message with instructions to reactivate the data service if you wish and are aware of the possible costs. If the user chooses not to do so, the data service will automatically resume as of the next calendar month.


The profile can be related to the size of the Data bundle, but this is not a necessity!
