On one hand, mobile professionals have had to deal with spotty cell coverage (especially indoors), painfully slow data download speeds, and unpredictable, outrageously expensive fees for international long distance and roaming, particularly for data transfer such as text messages and email. Meanwhile, Wi-Fi has made accessing data and the Internet affordable, but only if you’re carrying a laptop. And Wi-Fi didn’t help you make cheap calls unless you had a dedicated VoIP mobile phone.
With De-Fi, now you can do everything on ONE mobile phone that can call (and receive calls from) most countries for one simple, affordable flat rate, with all of the reliability benefits and data/Web access of Wi-Fi when you’re in a Wi-Fi hotspot.
De-Fi’s ground-breaking technology lets you reap all the benefits of Wi-Fi – including high-quality, carrier-class IP-based telephony – but provides traditional cellular as a backup when Wi-Fi isn’t available… all with one device. De-Fi’s software operates in the background, automatically detecting and connecting to allowed hotspots when they’re available, and switching seamlessly to cellular when they’re not.
