All incoming calls received over Wi-Fi calling are $0.
Wi-Fi calls placed to countries other than the U.S. from outside the U.S. are subject to the following:
- If you have a Simple Choice rate plan:
  - Wi-Fi calls made from any Simple Global country to any other country are $0.20/min (same as cellular).
  - Wi-Fi calls made from non-Simple Global countries to other countries are charged atWorld Class rates.
- If you do not have a Simple Choice rate plan, Wi-Fi calls made to other countries are charged atWorld Class Calling rates.
Keep in mind, you must disable data roaming when traveling internationally to avoid incurring data roaming charges.

All text messages (SMS) and picture messages (MMS) received over Wi-Fi are $0.

For Pay In Advance prepaid lines, calls made over Wi-Fi deduct from the plan bucket just like regular calls.
