Just got in the mail. Nice toy
Tried with call back and direct dial sims. All worked fine. Tried Beyond Wireless/AT&T-USA, Fido-Canada, Digicel-Bermuda, UM+, and Yackie Mobile. May also try with a T-Mobile/Tuyo chip when in a T-Mobile coverage area.
Dialing is by menu or virtual keyboard.
Texting is by handwriting recognition.
Amazing they can fit a phone in something this small. Receiver sensitivity is good. Tried calls both talking at my wrist (should be interesting trying that in public....), and via bluetooth.
Also has an MP4 audio/video player that plays either vertically or horizontally for video. Haven't converted files for it yet, but intend to. Also can play ebooks.
Instruction manual is in English and Chinese. No diagrams but can figure out most watch functions through the manual and rummaging through the menus on the phone.
USB cables provided to charge headset or phone. Cables connect either to a PC or to an included AC Adapter (110-240V AC; has rounds pins). Spare battery provided and sim cards easily install under the battery pack on the back of the phone.
USB drivers weren't included but were easily found by Windows XP on the internet (3 drivers were downloaded by the hardware installer when I plugged in the USB cable). USB cable can be used to either use the phone as a USB drive or as a communications cable to teather a device.
All in all a good value for US$157 with postage on ebay.
