Each data plan has a monthly limit. When more than one line of service has the same data plan, the data allotment is pooled for use by all lines on the same plan. If the modem data use exceeds the plan limit for a month, an email will be sent to notify the customer contact. Data overages are logged each day. When overage charges beyond the pool limit reach $50.00, customers will be notified and billed. For information about current additional charges, review the Cellular Data Service Provisioning Order form.
