No incoming calls. You only get free incoming SMS.
People who choose this option are those who want to put on hold their mobile services, but still keep their mobile phone number. If you cancel your plan, you will loose your phone number.
The plan with nothing can still be used for Addons or Pay as you Go (by the minute and per outgoing SMS). In order to do this, you must add funds in your Fizz Wallet.
I only have a data plan and it's perfect for me. I don't text (sms) because I'm always using messenger. And the 60min addons for 3$ is fine when client or family have to call.
Btw, fyi, without SMS you still can receive them for free. So I'm still able to receive my confirmation number from my services like Amazon or Steam, and my client or friends still can leave my a message in sms. I'll just have to call them or leave a message on messenger instead of sms.I'm saving a lots of money with Fizz
