Review: Kyocera DuraPlus for Sprint
The DuraPlus uses Sprint's CDMA network - rather than the older iDEN network - for PTT calls. Most users won't be able to notice the difference between the two. Only the most seasoned veterans of Sprint Nextel's iDEN services might be able to tell the two types of PTT services apart, but I doubt it. That’s a good thing.
Once you've added some DirectConnect contacts, reaching out to them is a breeze. In my tests, the delay in the time it took to send/receive PTT messages was just as short as it would be with an iDEN-based handset. The system works with other CDMA DirectConnect devices as well as older iDEN handsets.
The quality of the calls coming through the PTT service was acceptable, but even via speakerphone, not quite as loud as they should be.
The DuraPlus doesn't offer any surprises in the phone call department. Press the green send key to get at a list of all your calls. The most recent call in the log is highlighted with enlarged text, so it stands out nicely. Use the left soft key or text key to automatically send the highlighted number a message. The in-call options range from the typical phone book access to 3-way calls. You can also set up to 98 speed dials if you wish.
The contacts functions are simple and straightforward. From the contact list, the left soft key automatically initiates a text message.
