Are 900mhz ISM radios dependable for e-com

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.

ISM radios are limited by power and antenna type. You'll have about 3/4 of a mile coverage.

ISM radios, such as the Motorola DLR200 DLR600 and DTR700 radios, for communicating with other radios you will need to know the Group Profile ID Number and have your radio programmed accordingly.  For Direct Connect, you would need to know the 11-digit Private ID numbers of the radios you want to communicate directly with and have that info programmed in your radio.

The radios do come with a factory default program and will communicate with other factory default programmed radios, but good luck and finding anyone with a factory default program when the SHTF that is nearby within no more than a mile.  These radios cost almost $500.
