Why use a temporary number for Ultraio

A disposable non-VoIP number is the safest way to verify Ultraio: you avoid SIM-swap exposure, keep your primary number off Ultraio's servers, and can spin up additional accounts for business, testing or travel. Free public numbers are usually already burned — a dedicated number from VoIPStore is fresh and high-deliverability.
