Key Takeaways

  • A pre-trip inspection photo is a yard record. The customer or shipper gets a short SMS only if the job is delayed — not the tire close-up.
  • Crop odometer and defect. Do not MMS the whole bay.
  • Free is 1 device, 300 SMS lifetime, and 300 contacts. Platform price is devices plus send volume; MMS still bills the carrier.
  • Driver login / gate OTP stays off the inspection radio.
  • A failed inspection pages fleet and the assigned driver — not the retail consignee list.

Summary

Scenario 321 is field MMS for fleet and DVIR inspections — not household meters, not key safes, not claims. The yard photographs a defect before the unit rolls. That is evidence for maintenance, not a customer gallery. Service pricing is devices plus SMS send volume. You bring the phones and operator credit. Free is 1 device, 300 SMS lifetime, and 300 contacts.

Starter allows 2 devices: inspection radio vs OTP. Uncapped platform volume is not unlimited carrier MMS. Confirm types in Developer Center.

defect crop · fleet inbox · delay SMS

bay panorama never hits the APN

Fleet inspections are yard evidence

Internal: cropped defect, unit id, odometer. External: delay SMS only when a load will miss. Do not attach a marketing footer to a red-tag unit.

Transactional notifications, features.

If two inspectors fail the same tractor, the inbox owner publishes one driver SMS. Two MMS “do not roll” texts ten minutes apart are how you get a driver who ignores both.

Odometer and plate crops

Worker crops, strips EXIF, refuses empty frames. Test APN on the yard prepaid. DLR. MCP wraps REST only.

Fail stickers vs driver SMS

Auto-reply: “fail logged, unit id.” Never “you may depart.” Webhooks, setup.

Devices, volume, and airtime

A full yard of MMS will empty prepaid. Prefer portal for masters. We meter devices and platform volume. Free (1/300/300) is one lane proof.

Yard-shift operations

Charge, pairing, unit-id required. Downloads, pricing.

Decision guide

Ship when shippers cannot receive defect stills. Delay if techs MMS the camera roll. Not a CodeCanyon fleet pack.

Fleet checklist

  • Crop defect + unit id.
  • One driver SMS per fail.
  • OTP isolated.
  • Yard APN tested.
  • Developer Center types confirmed.

Next steps

Scenario 201 meters, scenario 261 keys, GSMA MMS.
