One number, everything a business phone needs
The app handles the number, the calls and the follow-up. AI takes the calls you can't.
A business number in one minute

AI answers when you can't
Missed calls, repeat questions and booking requests are handled by the AI agent, following the answers you write down.
Every call recorded and summarized
Read a short summary instead of replaying the whole call. The caller gets a text confirmation too.
Texts and bulk messages
Send and receive texts on the same number, and reach all your customers at once.
Share the line with your team
Several people can pick up the same number, so calls don't depend on one phone.

FAQ
Common questions
What is a 070 number?
070 is the Korean prefix for internet phone numbers. Businesses use it as a main line that works on a smartphone app instead of a desk phone.
Do I need any hardware?
No. Install the ZeroCall app (iOS or Android) or use the web app, open a number, and start taking calls.
How much does it cost?
Plans start at KRW 1,800 a month. Your first number is free for the first month, and plans above Basic get the Basic fee (KRW 9,000) off the first month. Prices exclude VAT and are prepaid.
Can we keep our existing main number?
Yes, for business customers. We port the number to ZeroCall, so the number your customers know stays the same.
Who runs ZeroCall?
Flover Inc., a registered facilities-based telecommunications carrier in Korea. We operate the lines and numbers ourselves.
