You must have a Plivo phone number if you wish to receive calls. You can rent a Plivo phone number in more than 60 countries from Phone Numbers > Buy Numbers on the Plivo console.
In the Plivo console, click on Phone Numbers > Buy Numbers. Specify filters for type and capability, and/or number characteristics for location, rate center, or LATA, then click Search. Plivo will display a list of all available phone numbers.
Click Buy Number next to the phone number of your choice.
On the Buy Number pop-up, review the information, then click Buy Number & Continue.
The number will be added to your account, and the monthly fee for the current month will be deducted from the credits in your account.
