Three ways to test and verify

Everything in CallVerifier revolves around manual call verification, SMS testing, and Truecaller bulk campaigns—so your team always knows where to work.

Manual call verification

Start verification calls yourself: pick country and provider, dial the target number, and follow status end-to-end. Full call history, timelines, and screenshot capture when your workflow records evidence—so every manual test is traceable.

SMS testing

Exercise SMS flows across providers and numbers: send tests, inspect delivery behaviour, and work through number inventory with filters built for operators—not spreadsheets.

Truecaller bulk testing

Run bulk testing campaigns with a Truecaller module: add numbers, generate jobs across number × provider combinations, and track pending, in-progress, completed, and failed work in one campaign view.
