Send and Receive SMS

Hi,

How can we receive SMS messages sent from our web applications to test the SMS functionality. Do you have a virtual phone# or something similar to receive SMS?

Thanks

No — LambdaTest and TestMu AI do not provide virtual phone numbers or a way to receive SMS on their devices.

What this means:

  • You can use their real devices to test apps

  • But you cannot receive real SMS messages sent to those devices

  • The phone number and SMS inbox are not accessible for testing

Why this happens:

  • Cloud device providers do not expose real phone numbers

  • SMS is restricted for security and privacy reasons

How to test SMS functionality instead:

  1. Use an external SMS service Services like Twilio or MessageBird give you real phone numbers and APIs to read incoming messages. Your app sends the SMS to that number, and your test retrieves the message using their API.

  2. Mock or bypass SMS in test environments Instead of sending a real SMS, return the OTP through:

  • an API response

  • logs

  • or a database

  1. Use a real physical device If you need true end-to-end testing, use a real phone with a real SIM card.

LambdaTest and TestMu AI are not built for receiving SMS. To test SMS flows, you need to use an external service like Twilio or a real device.
