Are 900mhz ISM radios dependable for e-com

[ULTRA2]

I just want to get comments on these radios if they're dependable during emergency use

ISN radios are not designed for voice, nor emergency operations. They are normally used for OT device control and monitoring. Usually the power is low, the ranges isn't very far per watt, and in general are typically programmed for some specific industry business.
