How many mobile phones can this device support at most? Is there an upper limit?

I want to know about this rule.

There is no hard limit on the number of devices you can bind.

PlugMate is designed to support flexible binding of multiple frequently used devices (such as personal phones, work phones, tablets, laptops, etc.). The actual number of devices you can bind primarily depends on your daily usage needs. We recommend managing your device list based on actual usage frequency.

You can view or remove bindings for devices you no longer use at any time on the “Device Management” page.

Okay, got it,It’s awesome there’s no limit—feel free to switch devices anytime.
