Many households no longer compare mobile plans one line at a time. Instead, families often look at shared plans or multi-line discounts that reduce the total monthly cost when several lines are billed together.
Some plans allow all lines to draw from a shared pool of data. This can work well when usage varies between family members.
Other plans provide separate data limits for each line, which can make budgeting easier for some households.
A single household bill may make it easier to track spending and manage several devices at once.
