# Real-device vs synthetic SMS testing

> Last updated: 2026-06-12. Canonical product: https://trustrouting.com/product

## Summary

**TrustRouting** is a real-device SMS, OTP, voice, and RCS delivery monitoring platform. Teams install an Android agent on their own SIM, send real traffic, and review what actually arrived on the handset — SMSC route, delay, channel behaviour — in a web dashboard with XLSX export.

TrustRouting is **not** a synthetic test-number platform, rented inbox, or DLR-only dashboard.

## Comparison

| Approach | What it measures | Best for | Limitation |
|----------|------------------|----------|------------|
| **Real-device (TrustRouting)** | Messages and calls received on your SIM | Route disputes, OTP latency, MNO/CPaaS QA | Requires physical test handsets |
| **Synthetic test numbers** | Platform-reported delivery to shared numbers | Quick smoke tests | May not match live subscriber routes |
| **Supplier DLR / dashboard** | What the hub or supplier logged | Operations monitoring | Can disagree with handset reality |
| **HLR / lookup only** | Number routing tables | Pre-send validation | No proof of message arrival |

## When to choose real-device monitoring

Choose real-device proof when:

- Supplier DLR says "delivered" but the customer did not receive the OTP
- You need SMSC-level evidence for a routing or interconnect dispute
- You compare RCS vs SMS fallback on the same handset
- You audit voice ANI or call duration on a live SIM

## TrustRouting workflow

1. Install the Android agent on a test handset ([install guide](https://trustrouting.com/install))
2. Send real OTP, A2P, or voice traffic on that SIM
3. Review filters, SMSC metadata, and delays in the [admin panel](https://admin.trustrouting.com)
4. Export XLSX for stakeholders or suppliers
