Send the same kinds of alerts you already send by SMS — voucher codes, welcomes, usage warnings, router and billing notices — on WhatsApp. You link one business number to NettPortal, then choose SMS, WhatsApp, or both for each alert on Notifications.
In plain language
Grow → WhatsApp is where you connect the phone. Grow → Notifications is where you turn WhatsApp on or off for each message type. Connecting the number does not replace SMS; you pick the channel per alert.
Each WhatsApp send uses 1 SMS credit from your organization (same pool as SMS). Both SMS and WhatsApp for one event uses 2 credits. This is not SMS Marketing (bulk campaigns) and not a personal chat app for staff.
viewSettings (Managers / operators typically have it). Agents cannot open these pages.Link a SIM used only for this ISP — not a personal WhatsApp. A personal account can be limited or banned. If that happens, customers stop getting alerts.
Fastest if the phone camera can see this screen. On the phone: WhatsApp → Linked devices → Link a device, then scan the code in the popup.
Use this when you cannot scan. Enter the WhatsApp number (local format is fine; the country code is applied from your organization country). On the phone: Linked devices → Link with phone number, then enter the 8-digit code.
If you already typed an international number such as +234…, that number is used as-is.
After the first successful connect, every alert type is set to Both (SMS and WhatsApp) so WhatsApp is on without turning SMS off. Change this any time on Notifications.
If WhatsApp is not linked yet, that section shows Connect WhatsApp instead of the channel buttons.
SMS stays short and fixed: voucher code, password if they have one, then Usage: and the status link.
WhatsApp sends a short receipt (code, plan, price, usage link) in one of three wordings, picked at random for each buy. If there is no usage URL, that line is left off.
Customer texts (vouchers, welcomes, usage, PPPoE) use your linked number. Router, multi-WAN, and billing alerts use NettPortal WhatsApp. Those still spend your SMS credits.
