Inbound pilot week: MO live checks on the rented DID

Inbound pilot week: MO live checks on the rented DID.

Essential Mobile Originated (MO) smoke tests for new DIDs

When launching a pilot project on a newly provisioned virtual number, performing systematic Mobile Originated (MO) live checks is the first line of defense against message delivery failures. Our platform utilizes Just-In-Time (JIT) provisioning accompanied by a temporary prepaid hold, eliminating static number pools and ensuring pristine line reputation. During day one of testing, verify that your DIDs are routing correctly across major carriers.

Webhook payload verification and inbox event streams

Inbound messages generate instant HTTP POST requests to your designated application URL. You must verify that your listener correctly parses parameters such as originator number, destination DID, message body, and timestamp. For complete schema details, inspect our guide on inbox events on rented numbers.

Mandatory STOP and HELP keyword processing checks

Regulatory compliance requires immediate and automatic handling of standard opt-out commands. Sending inbound test messages containing STOP, QUIT, UNSUBSCRIBE, or HELP helps confirm that account-level suppression rules function as intended before full production volume. Review the STOP and HELP policy to understand how the platform handles these mandatory signals.

Avoiding auto-reply loop risks and balance exhaustion

A critical mistake during inbound pilot week is configuring automated replies without strict safeguards. If an incoming message originates from another automated system or an auto-responder, a looping condition can trigger continuous billing. Consult our guide on inbound auto-reply loops to configure message deduplication, preventing your wallet from draining unexpectedly.

Pilot week operational thresholds and prepaid limits

To maintain network quality and protect your account from accidental overspending during early pilot testing, platform operations operate on predictable billing mechanics. Accounts start with a USD 20 prepaid floor to cover initial JIT number reservations and inbound message processing fees. As your pilot expands and inbound volume approaches USD 1,000/month, a soft review is triggered to ensure your traffic profile remains compliant.

Start with IOSOR

On the rented DID in week one, send a real MO from a handset. Prove the inbox event, the signed webhook, and STOP/HELP before any volume. Export the live-check sheet. This is a pilot proof, not an incident-week flood throttle.

IOSOR takeaway

A rented DID is not live until an MO comes back.

Do: handset MO, inbox row, webhook 2xx, keyword ACK. Don’t: call the number live because outbound MT already delivered.
