• Q4. How do I make a phone call with my JMP number?

The easiest way is to make a call from your Jabber app, if you are using a supporting app such as Cheogram Android, Conversations, Snikket, or Movim. Simply add a contact just as you would for messaging and then select the voice call option in your app.

• Q10. JMP currently only provides numbers in the USA and Canada. These numbers can make and receive both calls and messages with any country in the world.
