Why use temporary phone numbers for SMS and calls?

Temporary numbers give you flexibility: you can test international calling and messaging, separate work from personal life, and keep your real number away from one-time sign-ups.

International calling & presence

Test how your product behaves with numbers from different countries, check routing, and simulate global users without buying a full phone plan in each region.

Unlimited testing for SMS flows

Reuse public numbers as many times as you need for OTPs, login codes and notification templates, without spamming your real phone or your team members.

Safer than using your primary line

Keep your main number private. Use disposable lines for short-term trials, marketing funnels, and any signup where you don’t fully trust the destination.

Primary, secondary & alternative lines

Use your real number as a primary line, then add temporary numbers as secondary or alternative lines for beta tests, side projects, or short-lived campaigns.

Business & dedicated testing numbers

Keep a dedicated pool of test numbers for your business. Separate production traffic from staging, QA and automation, while still seeing real SMS content.

Online verification without friction

Quickly spin up signups, trial accounts and onboarding flows. Use temporary numbers for low-risk verification, and reserve your personal line for critical accounts only.
