Frequently asked questions

Are these tools free?

Yes. Every tool on this page is free to use, with no sign-up and no limit on how often you use it.

Is what I type stored?

No. The tools run in your browser. Numbers, messages and volumes you enter are not sent to Unecast or stored.

Do the tools work for any country?

Yes. The link generator knows the number format of 245 countries and territories, the pricing calculator covers all 47 of Meta's WhatsApp pricing markets, and the formatter and SMS counter work with any language.

Where do the numbers and rules come from?

From the original sources: WhatsApp's help pages for links and formatting, Meta's developer documentation and rate cards for pricing and limits, and the 3GPP standards for SMS. Each tool links to its sources and says when they were last checked.
