Twilio Lookup alternatives for UK mobile number risk checks

Q: What is a good alternative to Twilio Lookup in the UK?

If you need UK SIM swap, call divert and line type with a published GBP price and self-serve sign-up, TDS Risk Trust Score is £0.35 per check. Twilio Lookup remains a strong fit for global modular lookups and teams already on Twilio.

Q: How does TransUnion TruValidate compare on UK price?

TransUnion publishes UK prices on its G-Cloud price list: Mobile Risk £2.38 and Mobile Know Your Customer £4.91 per check pay as you go, falling to £0.52 and £0.95 at the highest volume tiers, plus £5,000 API setup and £5,000 annual maintenance from year 2, excluding VAT. TDS Risk is £0.35 per Trust Score check and £0.45 per Mobile KYC check, with no setup fee and no contract.

Q: How does Telebase compare for UK SIM swap checks?

Telebase lists $0.20 per SIM swap check on its UK page, with carrier data included and no annual commitment. Its SIM swap answer is SWAPPED or NO_SWAP. TDS Risk returns a riskLevel timing band and the exact simTimestamp, plus call forwarding, phone risk, line type and reason codes, for £0.35 per Trust Score check, and Mobile KYC identity matching for £0.45.

Q: Do I need approval from the mobile networks?

Not with TDS Risk. You use TDS's existing carrier approval across EE, O2, Three and Vodafone, so there is no separate network sign-off and you can go live in about 10 minutes. Other providers publish their own onboarding steps, for example, Twilio requires carrier registration for SIM swap and call forwarding, and Telesign enables SIM Swap on full-service accounts.

Q: Does Twilio publish a UK price for Lookup?

No. Twilio does not publish UK-specific prices for Lookup on its pricing page. Contact Twilio for UK pricing.

Q: Does Twilio publish a SIM swap price?

No. Twilio's Lookup pricing page lists SIM swap and call forwarding as "Contact sales". Docs say carrier registration is required.

Q: Is Vonage Number Insight still the right product name?

Vonage states that Number Insights will sunset on 4 February 2027 and encourages migration to Identity Insights. Prefer Identity Insights for new builds.

Q: How much does TDS Risk cost next to these options?

£0.35 per Trust Score check and £0.45 per Mobile KYC check, excluding VAT, pay as you go, no contract, 20 free checks on sign-up.
