Companion Chinese deep-dive (Shenzhen Lezhao Electronics): Robot mower overseas connectivity
A robot mower that loses its connection does not stop politely at the dock. It stops exactly where it is: half a lawn cut, a map it can no longer upload, an OTA update frozen at 60%. The customer does not open a connectivity ticket. They leave a one-star review that says the product is broken.
The data need is small. The stability need is not.
Positioning, job status and map deltas come to a few hundred megabytes a month. Volume is not the engineering problem. Uptime is. A mower is judged on whether it finished the lawn while nobody was watching — which makes connectivity the product, not a feature of it.
Guarantee one: switch carriers when the signal fades
Backyards sit behind walls, at the edge of a cell, in a garden where one operator is weak and another is fine. A single-operator SIM clings to the dying tower and fails slowly. A multi-operator or multi-IMSI profile hands the device to whichever network is actually serving that address.
Guarantee two: recover in under thirty seconds
After a reboot or a tunnel of dead signal, the device should reattach without the user touching anything. Reconnect time is measurable and comparable — ask every SIM vendor for it, then treat it as the number that predicts your ticket volume.
Guarantee three: coverage follows the sales map
If the product sells into Germany, Texas, Dubai and Japan, the SIM must already hold commercial agreements in all four. "It roams" is not the same as "it attaches locally", and the difference shows up as latency, as blocked ports, and eventually as returns.
Questions to put to a SIM vendor before you commit
- Which operators per country, and is it local attach or roaming?
- What is the measured reconnect time after a power cycle?
- Can a line be suspended for seasonal channel stock without losing the number?
- Can per-device usage be capped and alerted, so one firmware bug cannot drain a batch?

FAQ
How much data does a robot mower need per month?
A few hundred megabytes. Positioning, job status and map deltas are small; the peaks come from OTA updates. Size the plan for the OTA, not for the mowing.
Will one SIM work across the markets we sell into?
With a multi-country plan, yes. The thing to verify is local attach per country rather than roaming, because roaming policies change without notice.
What happens when a mower goes offline in a customer's garden?
The device should reattach automatically after a reboot, and the platform should raise an alert on the line so support sees it before the customer calls.
