Call and text worry-free on every plan

  • Free calls to the US & Canada

    With OpenPhone, you can make as many calls as you want to local and toll-free US and Canadian numbers. 

    JustCall limits your inbound and outbound calls on most plans. Outbound calls are limited to 1,000 mins/user/month and inbound calls are limited to 1,000 mins/user/month on the base plan.

    JustCall also charges extra for inbound calls to toll-free numbers. 

  • Free texting to US and Canada numbers

    JustCall limits businesses to 250 SMS and MMS messages per user per month in its base plan. 

Get as many numbers as you need

  • Every user gets their own number

    OpenPhone gives every member of your workspace a dedicated local or toll-free number. Share numbers for dedicated departments or locations. 

    JustCall limits teams to 1 local number per account on their base plan. 

  • Get a toll-free number on every plan

    Want to offer customer support nationwide with a toll-free number? 

    OpenPhone offers toll-free numbers in every plan.
