Can you test any SMS traffic?

No. Only traffic owned by the client or explicitly authorized by its owner. Unauthorized or third-party traffic is rejected at review.

Receipt confirmation, delivery latency, sender ID presentation, content integrity and, for voice, call completion and OTP audibility outcomes.

Which markets are covered?

Coverage depends on active testers per country and network. Submit your markets and we confirm feasibility during scoping.

Testing Service

Verify delivery where it matters.

Authorized testing of message receipt, voice-call completion, delivery latency, sender presentation and authentication outcomes — on real devices and live networks.

Discuss Coverage

What we test

SMS receipt confirmation

Did the message arrive, on which device and network.

Delivery-time measurement

Latency from send to receipt, per route and market.

Voice-call completion

Does the call connect and complete as expected.

Sender ID & calling-line

How sender information is presented to the recipient.

Content integrity

Does the message or call arrive complete and unaltered.

End-to-end OTP outcomes

Does the authentication journey complete for a real user.

Authorization first: iSmart Tester accepts testing only for client-owned or explicitly authorized traffic and endpoints. We never generate traffic on public third-party applications.

Structured failure evidence

When delivery fails, you need more than "it didn't arrive".

Timing

Send time, expected window, actual arrival or silence.

Network context

Country, operator, device and signal conditions.

Reproduction

Repeated attempts and consistent documentation.
