Agree the destination, network, test number and route reference. Confirm intermediate providers only where partner logs make them visible.

A2P focusedOTP & account verification
SMPP integrationAn agreed technical setup
Customer trafficDefined scope & limits
Match message IDs, timestamps and delivery reports with receiving-point evidence and available partner logs.
Prepare the agreed scenario
Record the intended destination, test number, sender and time. Use the customer’s own or expressly authorized traffic.
Evidence to review
Scenario reference, send event and original message ID where available.
Review the provider segment
If a hub is part of the agreed route, compare its supplied records. Map identifiers between systems where that information is available.
Evidence to review
Provider response, mapped message IDs and timestamps supplied by the partner.
Check the operator hand-off
Review the operator-side evidence and the available delivery status. An accepted submission is different from a final delivery result.
Evidence to review
Operator response or logs and final DLR, where shared for this test.
Verify the receiving point
Confirm what arrived at the agreed handset or SMPP endpoint. Compare the observation with the delivery report and follow up on differences.
Evidence to review
Receipt event, receiving endpoint and time. A SMPP receipt is not handset evidence.
Observed outcome
Record the receiving point, message ID and available timestamps. A gateway acknowledgement alone does not confirm handset delivery.
Repeatable check
Match the DLR to the receipt evidence. Review missing or delayed messages with the partner, then repeat the same scenario after a change.

Finding
A positive DLR was returned, but receipt was not observed on the controlled endpoint. This is a strong discrepancy requiring investigation, not automatic proof of fraud.
Example target: ≤ 5 sThis target is illustrative and is agreed separately for each project.
Next action
Match the message ID and DLR to receipt evidence. Investigate the discrepancy and retest; the example alone does not establish a cause.

Illustrative report with fictional data. No SMS are sent; these are not actual measurements of the applications shown.
Application names are used as examples and do not imply a partnership.
Evidence rule. A delivery mismatch can confirm a technical anomaly. Confirmed fraud or route attribution requires correlated operator, SMSC, signalling, CDR or billing evidence.
What we check
Receipt, timing and DLR accuracy. Sender, content and bypass checks use the evidence available from your network.
Route validation
Test selected destinations and mobile networks using agreed numbers and application scenarios.
Delivery verification
Compare the available delivery report (DLR) with receipt on the test number. Flag mismatches for review.
Delivery analysis
Record available delivery times. Compare repeated tests to find delays and recurring issues.
Detect route anomalies
Signs of SIM-box bypass
Check for signs of A2P termination through local SIM cards. Compare sender changes and receipt evidence with operator logs.
Evidence needed
An agreed reference message, receiving-point observations and operator routing or signalling records. A local sender number alone does not prove SIM-box activity.
Sender and content changes
Compare the received Sender ID, text and encoding with the expected message. Flag unexplained changes.
Evidence needed
The sender’s reference text and ID, the received message and applicable sender-normalisation rules. Separate unexpected changes from agreed transformations. A DLR alone does not show the received content.
Flash-call verification paths
Check for short verification calls in place of the expected SMS. Review caller numbers and timing with the operator.
Evidence needed
Call observations from an agreed test device or operator call records, including caller number and timestamps. SMPP alone cannot observe calls. A flash call can be a legitimate verification method; the event itself does not establish fraud.
From test to report
- 01
Application scenarios
Agree applications, countries, networks, receiving points and test limits.
- 02
SMSC and message analysis
Filter supplied SMSC/SMPP records by message ID, sender, destination, time and status.
- 03
Patterns across tests
Compare delays, missing messages and recurring changes by application, network and route.
- 04

What we doSet test windows, volume limits and acceptance criteria.
Next stepA shared scope with clear responsibilities.
Connect

InputConnection parameters, IP whitelist and routing configuration.
What we doConfirm the setup with the technical team and agree the first test window.
Next stepBoth teams are ready for the agreed test.

What we doShare findings → agree who investigates → repeat the same scenario after changes.
Next stepConfirm the retest result, then agree further monitoring, volumes and commercial terms.
Testing is performed on customer-owned or expressly authorized traffic. Destinations, applications and volumes are confirmed for each engagement.
SMPP integration
You confirm numbers, network access and routing. Together we agree the connection roles and delivery checks.
Example: receiving messages from the operator
The operator routes the agreed incoming A2P traffic for allocated test numbers to the Routesms SMPP receiving endpoint.
- Agreed senderCustomer-owned / authorized trafficSMS
- Agreed routeProvider segments where applicableSMS
- Mobile operatorTest numbers & gatewaySMPP
- RoutesmsSMPP receiving endpoint
Review data: the receipt at Routesms, plus source-side logs and DLR only when the relevant party supplies them.
Confirmed observation: receipt at the SMPP endpoint.Example: submitting tests to the operator
If included in the agreement, Routesms submits test messages through the partner’s SMPP endpoint to the selected receiving point.
- RoutesmsAgreed test submissionSMPP
- Partner endpointOperator / messaging gatewaySMS
- Agreed routeOperator-side routingSMS
- Test receiverAgreed handset or endpoint
Review data: submission response, available DLR and evidence from the agreed receiver. Keep acknowledgements and receipt observations separate.
Confirmed observation depends on the receiving point used.The diagram shows possible connection roles, not a default configuration. Receiving an SMS at an SMPP endpoint verifies that endpoint, not delivery to a physical handset.
- 01
Confirm the test scope
Countries, networks, approved numbers, sender scenarios, traffic direction and acceptance criteria.
- 02
Exchange connection details
Endpoints, IP allowlists, ports, bind roles and credentials through an agreed secure channel. Confirm transport protection and access rules.
- 03
Validate the SMPP session
Check the bind, connection health and agreed message direction. Align throughput limits, addressing, encoding and DLR handling.
- 04
Run a limited pilot
Run agreed test cases. Capture IDs, gateway responses, delivery reports and receipt evidence where available.
- 05
Review and retest
Assign each issue to the responsible team. Repeat failed or delayed scenarios and compare the new result.
- 06
Agree the next scope
Confirm monitoring frequency, support contacts, limits, volumes and commercial terms based on the pilot.
What does each confirmation mean?
submit_sm_resp
Acknowledges the submission request. A successful response does not mean that the SMS reached the handset.
DLR
A delivery report states the provider’s reported outcome. Correlate it with the original message ID and receipt evidence.
deliver_sm
Can carry a received message or a delivery receipt. Interpret the message type and configured endpoint before drawing conclusions.
