How to get a US business number for calls, SMS & WhatsApp

Short, practical answers to the questions people ask most about business phone numbers — and how to do each one with G100.

Two clear paths

Pick the WhatsApp path that matches you

G100 separates everyday WhatsApp on your number from bulk Cloud API marketing. Don't buy the $10 add-on unless you need broadcasts and templates.

Path A · $1.95/mo

Personal WhatsApp on your US number

Buy a G100 US number, then register that number on WhatsApp or personal WhatsApp Business — for everyday chats, OTPs and calls/SMS in one app. No Cloud API required.

  1. Create a G100 account & buy a US number ($1.95/mo)
  2. Open WhatsApp → register using your G100 number
  3. Call, text and chat — personal number stays private

Path B · +$10/mo add-on

Bulk WhatsApp Cloud API

For marketing at scale: official WhatsApp Business Cloud API with shared team inbox, broadcasts, message templates and automation. Number still billed separately at $1.95/mo.

  1. Start with a WhatsApp-ready G100 number
  2. Add the Cloud API add-on in the dashboard ($10/mo)
  3. Connect via embedded signup — inbox, broadcasts, templates
