Isolated Operation

When you lose network coverage during a phone call, Private call, group call, or data transfer, the call or data transfer ends. But you can make and receive new group calls on the Hub you last used.

If the One Touch PTT settings on your phone would prevent you from making group calls on the Hub you last used, these setting are overridden while your phone is in Isolated Operation.

Important: You cannot make Emergency Group calls in Isolated Operation, even if the Hub you last used is the designated emergency Hub. You must have network coverage to make Emergency Group calls.

If the designated emergency Hub is the Hub you last used when you lost network coverage, your phone treats the Hub you used before the designated emergency Hub as the Hub you last used.
