Branded SMS & OTP in Pakistan: Buyer Checklist
Branded sender IDs build trust — but only if OTP still arrives and logs stay auditable.
Why branding changes open rates
A named sender beats a random number for bank-like trust. Operators gate masking — plan 24–48 hours for approvals.
OTP is a reliability product
Login and payment OTP must prefer delivery certainty and clear failure codes over fancy dashboards.
API checklist
Ask for send, status, webhooks, idempotency guidance, and sample payloads your engineers can paste today.
WhatsApp as complement
Some flows notify on WhatsApp after SMS. One vendor for both reduces glue code.
WhattNexus approach
Use WhattNexus SMS routes for OTP/branded traffic and WhatsApp modules for conversations and campaigns — one login, shared reporting culture.
