Thousands of niche apps—including otr—implement SMS verification to prove humanness during signup, password recovery, or payment setup. Even when otr is not a household name, the same telephony rules apply: VoIP and public recycled numbers fail because abuse teams maintain global blocklists.

Testers, privacy users, and operators launching otr integrations should order a dedicated carrier line per verification rather than risking a personal SIM on an unfamiliar app's data policy.
