Can I add a second calling plan to my Oi VoIP account?
Yes. You can have a separate calling plan for each port on your telephone adapter. For example, you can have a 500 minute plan to Europe with a local U.S. phone number associated with one port, and an unlimited plan to the U.S. and Canada with a U.S. toll-free number associated with the other port. You can also add additional phone numbers to each calling plan. To add a calling plan, login to the online account center. Click the Manage Plan link on the left side of the page and then click the Add Calling Plan link and follow the instructions.
