Motorola Nextel i365is
Any one have any information about this. We have a substantial investment.
Your new phones would offer the same PTT service, but on the CDMA network instead of the iDEN network.
As far as I know, Sprint has yet to announce any CDMA Direct Connect phones that are rated I.S. (and therefore suitable for a refinery.) You should contact Sprint to find out what replacement options they might be working on (but haven't announced) to fill your need.
Either way, Sprint will be contacting your company sooner or later to work out replacement phones. They won't be leaving customers stranded; there will be plenty of notice and special offers to upgrade.
