How do calls show up on a phone bill, and do they use Wi-Fi or data?
Calls may show up on your phone bill, but it varies based on your carrier.
For some plans, your phone bill may show the incoming number and that the inbound call is being forwarded. For other plans that don't display forwarded calls, you might not see the calls on your phone bill since all inbound calls are being forwarded to a Firewall number.
Firewall will use data for inbound calls, and the amount of data used depends on how long the inbound call is. Your data usage rates will vary based on your carrier and phone plan. If you want to use your minutes for inbound calls instead of data, you can use the switch to cell feature after answering an inbound call.
