No. FluxChat links your existing WhatsApp or WhatsApp Business number the same way WhatsApp Web does. Keep using WhatsApp on your phone as normal.
FluxChat isn't an official Meta product. Use it for messages people expect from you, like receipts, vouchers, reminders and replies, and it works well. Sending large promotions to people who don't know you can get any number restricted by WhatsApp, so FluxChat paces messages and sets daily limits to help.
No. After you link the number, messages go out even when your phone is off. Open WhatsApp on the phone at least once every 14 days to keep the link active.
Yes. That's what it's built for: payment receipts from PesaFlux, WhatsApp next to SMS on FluxSMS, and vouchers and reminders from Spidlan.
Monthly per number, by M-Pesa. The free trial needs no payment details.
