Predictable and Cost-effective

Data pooling is a cost-effective mobile plan option for organisations with many staff using devices. Sharing monthly data between all devices means those who use less data don’t get charged for wasted data that isn’t used. Similarly, those who use more data don’t receive high bills and excessive charges because they will use excess data in the pool that would otherwise be wasted.
