Not a bad idea for a product line, my only question would be how would they manage the dslam for the number of lines?

For example what would happen if the dslam has 100 lines, considering that ADSL lines are dedicated to a telephone line, if they have 100 pre-paid customers on that dslam, with very small usage would that mean Eftel could not add more customers, and potentially not cover the operational/capital costs of running the dslam
