Pricing
Vonage Number Insight pricing is country-variable rather than a single global rate. Exact costs depend on the country of the phone number and the tier of lookup requested (Basic, Standard or Advanced); per-country rates are available from the Vonage dashboard after account creation.
Telebase is €0.20 per SIM swap check (€200 per 1,000 checks) regardless of the country queried, and invalid numbers and failed requests are not charged. Carrier, number type and active status are all included in that price. The rate does not vary by country, in contrast to the tiered, country-variable model described above. New accounts start in the sandbox with test keys, which are never charged. See carrier lookup API pricing compared for a three-provider overview.
The replacement: Vonage Identity Insights
Vonage's replacement for Number Insight is Vonage Identity Insights, a new product that includes SIM swap detection alongside carrier and number type data. Telebase's SIM swap signal is built on the GSMA Open Gateway / CAMARA network standard that the industry is converging on for SIM swap queries.
Teams currently on Vonage Number Insight will need to evaluate whether to migrate to Identity Insights or move to an alternative. The migration is not automatic: Identity Insights is a different product with different integration requirements. If you are mid-evaluation, factor in the February 2027 deadline.
Which is right for you
You are already using Vonage Communications APIs for SMS or voice, and consolidating vendors matters more than per-query cost. Migrating to Identity Insights keeps you in a familiar integration and support environment.
You want fraud and KYC signals on a flat per-query price with no annual commitment; you want SIM swap access without running your own carrier registration; or you are evaluating alternatives before the Number Insight sunset and want to compare against a specialist tool.
