The only vendor I know of who has profitably went with any type of PTT function is the US company NexTel with a motorola iDen service. There was an attempt by Verizon to market a similar product (I believe it was also iDen technology, but could be mistaken) but network provisioning was half-hearted and had lags that literally ranged to minutes for a message to be received. For something marketed as "Walkie-talkie", quite disastrous to sales and client retention. The Verizon package died a quick and horrible death leaving only NexTel as a vendor providing such a service (I've heard some rumors of Sprint toying with it, but since acquisition...) Of course the iDen standard is a bit different than the standard proposed by OMA. I DO know that I saved quite a bit using iDEN PTT comms at work and at home due to the flat rate, but the plans were substantially higher as there is no competition. In the US there is little incentive to substantially increase the levels of service to what is fairly standard elsewhere in the world. Vendors lock their phones to only be capable of operating on THEIR network, even if their competitor uses the same equipment, services are primitive compared to anything available on the Pacific rim and Europe, indeed primitive compared even to the middle east! That's what "one stop shopping" and "off the rack" purchasing does for you.
