free incoming call with Sero plan?

I want to switch to Sero plan, but before this I want to know if it includes free incoming calls. It’s not said anywhere on the website. If it doesn’t, then can I add them to the sero plan?

The Sero plan doesn’t include free incoming calls and you even can’t add such to the plan, but it’s not necessary as it comes with loads of minutes.

You can add earlier nights. There’s an option for nights starting at 7 for $5 and starting at 6 for $10.
